HKMA Seventh
Distinguished Lecture:
"Basel II: Back to the Future"
4 February 2005
Speech
by
Jaime Caruana
Chairman of the Basel Committee on Banking Supervision
and Governor of Banco de Espana
1. Introduction
Let me begin by expressing
my gratitude for this invitation to participate in the "Hong
Kong Monetary Authority Distinguished Lecture". I am honoured
to join the list of prestigious speakers who have discussed critical
issues in economics and finance in this forum, issues made
especially prominent by the important role that the Hong Kong
Monetary Authority plays in promoting financial stability under the
leadership of Joseph Yam. From my perspective as Chairman of the
Basel Committee on Banking Supervision, I am indebted to Mr Yam for
his support and initiative in contributing to the development, and
now the implementation, of the new bank capital framework, or
"Basel II".
"Nothing endures but
change," wrote the ancient Greek philosopher Heraclitus more
than two thousand years ago. In a world where change is the only
constant, success depends on the depth of our awareness of the risks
and rewards on the horizon and on the quality of our preparations to
respond to them appropriately. That is true not just in the banking
industry, but certainly also in the formulation of public policies
geared to promoting more sustainable economic growth through greater
financial stability.
Today I would like to
address the importance of adopting a forward-looking approach in our
framework for financial stability. At the same time, following the
advice of the Italian statesman and philosopher Machiavelli that
"whoever wishes to foresee the future might consult the
past", I would like to make the case that, to ensure a sound
regulatory system for the future, we must look carefully back at the
lessons of the past.
It seems especially
appropriate to discuss, here in Asia, the important relationship
between financial stability and sound growth. After enduring a
period of regional financial distress in the late 1990s, Asia’s
re-emerging dynamism and growing stature can be seen in many
indicators: for example, in its capacity as an importer of raw
materials and foreign direct investment, and as an exporter of
manufactures, financial capital, etc. Asia is a central partner with
the rest of the world through its roles both in trade and finance.
Indeed, in a recent address
at the Centre for Banking and Monetary Studies in Geneva, Mr Yam
offered an accurate overview of Asia's vibrant potential. He set out
some impressive figures such as the amount of foreign reserves held
by Asian economies, the amount of portfolio and direct investment
going into and coming out of the region, and the high level of rates
of private-sector saving, which is increasingly institutionalised
and professionally managed. Certainly, Hong Kong is a prime example
of the enormous potential that is being realised in Asia. Because of
the openness of its economy and the vitality of its business
environment, Hong Kong serves as an important reference point for
the world.
Hong Kong
has captured the world’s attention artistically as well,
especially through the recent work of the screenwriter and director
Wong Kar-wai. His recent film, 2046, has rightly enjoyed acclaim,
but it is the film’s unique perspective on time that might be
interesting to contemplate today. In his film, as many of you may
know, an author writes a book about the future, but gradually we
realise that he is actually exploring his past. With apologies to Mr
Wong and with deep respect for his beautiful film, I might venture
to say that we can draw some parallels with our discussion today. As
I have just suggested, I believe that in order to secure financial
stability in the future, we must explore and understand the risks
that have endured since the past.
If I may draw on my own
artistic license, I’d like to reinterpret the premise of Mr
Wong’s film slightly. Let’s consider an author, perhaps a
central banker or a supervisor, who lives in the year 2046 and has
the benefit of the perspective provided by the passage of the first
half of this century. What might such an author write about the main
determinants and evolution of financial stability during the first
five decades of the twenty-first century?
It is my hope that in that
book of the future, the Basel II framework would be portrayed as a
revolution in our approach to financial regulation. It would
represent the introduction of a new regulatory and supervisory
paradigm, one premised on the need to begin to depart from blunt
requirements and instead to develop rules that incorporate nuance,
rules that align capital requirements more closely to the actual
degree of economic risk a bank faces. Our author might write that
Basel II represented an important step forward in continuing to
replace static rules with rules that offer incentives for firms to
improve constantly their internal governance and management of risk.
And that it marked a milestone in the trend toward leveraging the
power of the market place to exert discipline over firms’
decisions and strategies, such that other marketplace participants
can better serve as effective allies of regulation and supervision
to achieve financial stability.
Yet I must confess that,
with the evolution in practices and technology that can reasonably
be expected by the year 2046, the Basel II capital framework
released in June 2004 might well be judged to be excessively simple.
Still, its greatest virtues might be considered its forward-looking
nature and its flexibility, and its ability to adapt to new
circumstances and to the emergence of better risk management
practices.
I was tempted by this flight
of the imagination to frame my remarks today as the views of that
author looking back at the work we are undertaking in 2005. In
truth, though, I thought it might depart too much from the usual
field of play of central bankers and supervisors. Instead, I’d
like to share my views on how the elements of Basel II take us
“back to the future,” not unlike the journey of Mr Wong’s
author in 2046 from the future to the past. In many ways, Basel II
brings us back to a traditional focus on risk, but with the benefit
of the most advanced techniques emerging today and into the future.
2. Overview
Specifically, I would like
to try to address four key points.
Firstly, I would like to
consider the current framework for promoting financial stability.
I will argue that, despite significant progress, our policy
and decision-making framework for financial stability is still
incomplete, especially if we draw a comparison with the framework
for monetary stability. That
said, there are a number of lessons we have learned in recent years
that can be useful for the future, and which we have taken into
account in designing the new Basel II capital framework.
One of the most important of these is the very real and
positive contribution that sound risk management practices can make
to promoting financial stability.
Therefore, in the second
part of my intervention, I would like to explore in more detail some
of the most important recent trends and developments in risk
management theory and practices, and also the impact that these
developments can have both on individual firms and on the economy as
a whole. I will cover three trends in particular: firm-wide
assessment of risk, risk aggregation and risk transfer.
This will lead me to the
third part of my intervention: the challenge of devising a
supervisory response which harnesses these developments for the
benefit of financial stability. As
I will argue, it is critical to ensure that our supervisory and
regulatory structures are compatible with the best practices in risk
management today. But I believe that our structures must go beyond
that and actually encourage firms to continue to improve their
measures of risk exposures and their approaches to mitigating them
in the future. This
forward-looking approach forms the basis of Basel II.
In the final part of my
intervention, I will explore some of the implications of Basel II
that received some attention in recent times: namely, the potential
impact of the new framework, both on capital flows and on global
competition.
My purpose today is not to
describe Basel II in detail, but rather to highlight the dynamic
processes that it stimulates. I
do not claim that Basel II covers all the areas and refinements
needed to complete the framework for financial stability, but it
does make a landmark contribution by incorporating a new
forward-looking approach, to banking regulation and supervision,
which is, at the same time, consistent with the lessons of the past.
3. Framework for
financial stability.
Beginning with my first
topic - the framework for financial stability - allow me to make a
final reference to the hypothetical book that might be written in
2046. I would not be surprised if the author of that future book
noted an interesting contrast that existed at the beginning of the
twenty first century. Although we have a well-developed framework
for debating and conducting monetary policy, our thinking on
financial stability is less advanced.
As an example, in the
monetary field we have agreed on a definition of monetary stability
– namely price stability. We have a framework of analysis that
allows the causes and consequences of price instability to be
studied. And, moreover, we have a highly developed decision-making
framework for pursuing monetary policy, which has almost universally
adopted the principles of central bank independence and primacy of
price stability as the goal of monetary policy.
In comparison, and despite
significant progress during the last decades, we are not nearly as
far along with financial stability, and there are areas where we
still have something to learn. We
don’t have a clear and measurable definition of the term financial
stability and, in most cases, nor do we have a clear policy or
decision-making structure for pursuing financial stability, unlike
in the field of monetary policy, in which many central banks follow
well-defined strategies which in one form or another respect the
principle of “constrained discretion”.
Achieving a coherent
approach to financial stability may be challenging, if only because
it requires a consistent combination of macro and micro elements and
because of the large number of interested and participating parties.
Also, it should foster financial innovation, and ensure a level
playing field.
However, I think that our
future author might take some comfort from the fact that
supervisors, central bankers, policymakers and others learned
valuable lessons in the late 20th and early 21st
centuries, which will remain valid for the rest of the century.
Let me outline four of those lessons.
First, we have learned of
the need for businesses and consumers to have access to credit on
fair and reasonable terms, through all stages of the business cycle,
so that the economy can grow through the financing of the best
opportunities.
We have learned that we need
an efficient and resilient payments system to maintain the flow of
funds through the economy at all times. We need financial markets to
remain active, liquid and trusted, regardless of events in the
economy. And we know that, for all these things to occur, our
financial institutions must be led by responsible individuals, must
operate transparently, and must serve the interests of depositors
and shareholders alike.
Second, we have identified
some characteristics of financial instability.
For example, financial instability may reveal itself via
excessive volatility in asset prices, which can move substantially
away from the value which, in principle, their fundamentals would
warrant. To be sure, a certain degree of volatility in asset prices
is simply the reflection of the normal workings of markets.
Likewise, poor results posted by a specific financial institution,
even its bankruptcy, may not have systemic implications.
However, financial instability may be very costly if it is on
such a scale as to cause harm in the real economy.
These considerations allow
us to draw a relevant conclusion: the pursuit of financial stability
calls for increased attention to a combination of micro and macro
factors and must be based on a broad range of tools which we should
all seek to strengthen.
Third, we have learned the
importance of sound macroeconomic policies and an appropriate
institutional framework, as well as of prudential regulation and
supervision, and consumer awareness and understanding. This is an
extremely important point and even though it is not my main subject
today, I would like to briefly underline two elements.
Firstly, there is a broad
consensus about the importance of promoting the implementation of
appropriate macroeconomic policies.
Nobody has any doubts today about the need to promote price
stability. However, this is not a sufficient condition for ensuring
financial stability, which demands other additional measures.
These include, for instance,
fiscal discipline, and the design of exchange rate policies that
ensure the consistency of the exchange rate system chosen with
domestic policies, and that contain vulnerabilities associated with
exchange rate instability in the different sectors of the economy.
Macroeconomic policies must also be consistent and sustainable over
time. Indeed, unstable macroeconomic settings are one of the main
causes of excessive volatility on financial markets.
Secondly, an appropriate
institutional framework is also needed. In particular, a set of
mercantile and civil laws must be in place, including the treatment
of bankruptcy situations; accounting obligations that ensure the
uniform representation of economic events; external auditing
requirements; guarantee funds providing appropriate safeguards;
independent supervisors with operational capacity, etc.
The legal structure and its application by the judiciary
should ensure the respect of property rights and equality before the
law; in sum, legal security.
The need for this set of
minimum prerequisites is reinforced by the "Core Principles for
Effective Banking Supervision”, which are invaluable as a tool for
the evaluation of supervisory systems.
In this respect, let me mention also the excellent work of
the Financial Stability Forum over the last years in bringing
together various standards issued by a number of bodies.
In summary, even though the
framework for financial stability is not as comprehensive as in the
case of price stability, significant progress has been made in all
of these areas in recent years.
There is a fourth lesson
that is particularly relevant for this presentation, and it is a
lesson that we have learned from periods of bank resilience in times
of stress. During the past few years, financial markets have
experienced a series of significant shocks.
However, the banking system has been able to cope with them
successfully. Financial innovation, the existence of deeper
financial markets with a great variety and availability of
instruments to transfer risks, and the improvement of the capacity
of financial institutions to understand and manage their risks are
key ingredients in explaining the resilience of the financial system
during the period of shocks. And that leads me to my next point:
important trends in risk management.
4. Recent trends in risk management
Financial stability is a key
precondition for sustained growth.
It is crucial, therefore, to find reliable ways of
identifying risks to financial stability and, in particular, to
banking stability, and to try to manage these risks in the most
effective way. Indeed, as experience has repeatedly shown, both
inside Asia and elsewhere, having a solid and well-run banking
system not only greatly reduces the likelihood of shocks originating
inside the banking system but also makes it less likely that shocks
arising elsewhere in the economy are amplified through the banking
system.
Financial service providers
have long competed on their ability to provide products and services
tailored to each customer’s needs and profile. Traditionally, a
bank’s balance sheet and earnings offered insight into the quality
and results of its transactions with customers, but those historical
measures reflect only the outcome of past decisions. A bank’s
ability to thrive in the future – and the ability of the banking
sector to act as a source of credit to businesses and consumers
alike – depends instead more on the kinds and levels of risk that
its transactions entail. For most of the history of banking, banks
could assess those risks only in a highly subjective manner and
without significant confidence in the quality of such assessments.
However, financial
innovation and advances in the measurement and management of risk
have fundamentally changed how banks and other financial service
providers approach their businesses. Three trends are particularly
prominent and have been analysed by the Joint Forum.
First, one of the most
notable advances in risk management is the growing emphasis on
developing a firm-wide assessment of risk.
Firm-wide risk assessment
Improvements in technology
and telecommunications have made it easier for firms to gather,
collect and analyse large amounts of data on their exposures and
business activities efficiently and increasingly in near “real
time.” To make the best use of firm-wide data, many organisations
have established a dedicated risk management function to foster more
highly integrated and systematic approaches to risk measurement and
management. The risk management function typically promotes the use
of common risk measures across business lines. It can then report
the firm-wide risk data to senior management.
Even though no single model
for organising an integrated risk management function has become
dominant, all firms that establish integrated risk management units
are highly dependent on the quality of their information technology
to collect, analyse and report firm-wide data efficiently and
effectively. Some participants have found that the greatest
challenge in developing a centralised risk management structure lies
in constructing compatible and efficient management information
systems across all of their businesses. As a result, they devote
substantial resources in terms of personnel and expenditures to the
maintenance and enhancement of their management information systems.
This trend is important for
two reasons.
For one thing, comprehensive
firm-wide assessment of risk and consistent reporting helps to
ensure that the firm is aware of the wide range of risks to which it
is exposed, that it understands the relative importance of various
risks and how they may interact, and that the firm is less likely to
ignore material sources of risk. This facilitates early detection
and resolution of problems.
For another, this integrated
risk management function requires a balance between the
centralisation of some functions within the group as a whole, and
the need to be close to local markets to incorporate better
knowledge of local needs, risks, sensitivities and regulations.
This, in turn, raises issues of co-ordination and communication for
both internationally active banks and also supervisors, about which
I will say more later.
Risk aggregation and quantification
Collecting risk data across
many business lines has catalysed further efforts to aggregate those
measures of risk by quantifying them in a more rigorous and more
consistent fashion. This quantification of risk is the second major
risk management trend identified in the Joint Forum report. It is
not a new concept. In the insurance industry, for instance,
actuaries have long sought to estimate the likelihood of various
events taking place. What is new is that, in recent years, financial
risk managers and researchers apply mathematics, statistics and
modelling to many risk exposures that were previously not thought to
be readily quantifiable.
In the banking industry, for
example, statistical and computational analyses developed for
evaluating exposures to market risk led, over the past decade or so,
to the application of similar techniques to credit risk. The
introduction of increasingly reliable estimates of the drivers of
credit risk, such as the probability of default, led to many of the
proposals that form the basis for the new Basel II bank capital
framework.
The Joint Forum found that
the “ultimate expression” of risk aggregation is the summation
of many types of risk into a single risk measure. This measure,
often called “economic capital,” estimates the amount of capital
a firm requires to protect itself against all risks with a certain
degree of confidence. The benefits of developing more aggregated
measures of risk across diverse business lines are especially
appealing to complex financial organisations whose activities span
many kinds of activities. As a result, it is not surprising that
large, mixed financial conglomerates have tended to invest most in
the development of economic capital estimates.
Using the concept of
economic capital and its elements, banks can develop sound policies
for monitoring exposure limits, risk-adjusted pricing policies and
sound provisioning practices based on the inherent risks of the
portfolios. They can also measure returns and assign capital on a
risk-adjusted basis.
Let me add a word of
caution. Despite the
significant progress made in the banking industry in the use of
models and new technologies, banks still depend largely on risk
managers’ expert judgement. Quantifying risk involves making
assumptions and judgements. And no model, and no software package,
no matter how sophisticated, can ever replace the skills of a
trained, experienced and conscientious risk manager.
That is why we have made sure that the Basel II framework is
much more than numbers and models.
Such judgement should be reinforced, however, with the best
possible information, techniques and tools for processing that
information. To the extent that risk assessment and control methods
become more formalised and rigorous, this will lessen the likelihood
of making bad decisions. It will also contribute to the prompt
detection of errors and deviations from targets, allowing banks to
implement corrective measures at an early stage.
The first two trends that I
have cited relate to the internal efforts firms undertake to
identify and measure their risks. The third trend I’d like to
highlight concerns the dramatic increase in the use of transactions
designed to transfer exposures to risk, especially to credit risk,
to outside counterparties and even to investors.
Credit risk transfer
This past autumn, the Joint
Forum released for public comment a study on the current use of
credit risk transfer activities among financial service providers,
along with a series of recommendations on how to promote sound risk
management practices in this area. In recent years, the markets for
credit derivatives, credit default swaps, collateralised debt
obligations and other products have grown tremendously, providing
financial service providers with new mechanisms through which they
can reduce their direct exposure to credit risk. Such tools may also
help to reduce concentrations of risks in particular firms.
I think that the emergence
of these new channels for re-packaging and selling off credit risk
serves as another means of looking forward to the future to manage
risk. In this sense, the rapidly expanding secondary market for new
credit-risk related instruments bears witness to the innovation and
the search for new ways of managing risk that is so vital to the
continued evolution of the financial sector.
However, we must remember to
look back at the fundamental risks involved in these practices. The
sale to outside parties of credit risk packaged into new instruments
helps, of course, to transfer the risk, but the credit risk still
exists.
While the transfer of risks
to institutions or households that are better able to withstand them
is a positive factor, and one of the structural explanations for the
resilience of the banking sector during recent periods of stress, we
should be conscious that this development may introduce some new
risks into the system, such as operational risks, which require
adequate treatment. Sellers of credit-related instruments face some
degree of legal risk, for example, when new instruments are issued
and their enforceability in courts has not yet been tested.
Likewise, the creation and management of the new products can put
strains on legacy risk measurement and management systems that were
not intended to handle them, creating new possibilities for
operations to fall short or even to fail in some way, creating
losses.
These advances in the
technology and practice of risk management introduce unique
opportunities for public authorities to promote greater stability.
I’d like now to turn to the efforts that banking supervisors are
undertaking to respond to these recent trends. This represents the
next topic I’d like to address today.
5.
The supervisory response: Basel II
Against this background of
increasingly sophisticated risk management practices, heightened
complexity in the financial markets and stronger interaction between
the real and the financial economy, the Basel II process started
more than 5 years ago. Rather than simply resetting the quantitative
standards, we sought to develop a new forward-looking approach that
would be more sensitive to the actual risks that banks take on, one
that would ensure a level playing field for banks that compete
globally, one that would be better able to evolve with, and indeed
encourage, future improvements in the measurement and management of
risk, and one that would be well-anchored on a solid corporate
governance structure and a sound risk culture.
If you allow me, I will draw
one more parallel between monetary stability and financial
stability. I would say that Basel II incorporates some of the key
basic principles that are also built in modern approaches to
monetary policy and which have successfully resolved the debate
between rules and discretion: a flexible and forward-looking
approach, anticipatory rather than reactive behaviour to risk, and
the need to take into account market views.
The new capital framework is
much more comprehensive than the 1988 Accord for many reasons: it
applies to a wider scope of entities within banking groups; it
offers a menu of different alternatives to fit different
circumstances; it encompasses additional risks, in particular
operational risk; it widens the recognition of credit risk
mitigation techniques; it sets out a thorough framework for
securitisation transactions; and, most importantly, it is based on
three mutually reinforcing pillars.
The first pillar aligns the
minimum capital requirements more closely to banks’ actual
underlying risks. Qualifying banks will rely partly on their own
measures of those risks, a rule that helps to create economic
incentives for banks to improve those measures.
The second pillar,
supervisory review, captures the view that capital supervision
requires banks to enter into a dialogue with their supervisors on
the processes and internal estimates that they develop to determine
how best to navigate the risks and rewards that they encounter. That
includes making decisions on how much capital beyond the minimum
requirement a firms should hold.
The third pillar, market
discipline, strengthens external incentives for prudent management.
It strengthens the ability of marketplace participants to reward
well-managed banks and to penalise poorly managed ones by enhancing
transparency in banks’ financial reporting
By relying on an
“efficient frontier” of three very different policy approaches,
Basel II is intended to help supervisors to promote the adoption of
sound practices today, to support efforts to improve those practices
tomorrow, and to nurture a stronger risk management culture overall.
In many ways, Basel II brings us back to a traditional focus on
risk, but with the benefit of the most advanced techniques emerging
today and into the future.
As I noted at the beginning
of my intervention, my purpose today is not to describe Basel II,
but rather to highlight those elements of the framework that set in
motion dynamic processes that will enhance banks’ safety,
efficiency and soundness, thereby strengthening the stability of the
financial system as a whole and ensuring that it can better serve as
a source for credit and growth for the economy.
The comprehensive framework
of Basel II provides four transmission channels for influencing
financial stability: first, by setting more risk-sensitive minimum
regulatory capital requirements, so that regulatory capital is both
adequate and closer to economic capital; second, by providing
incentives to encourage improvements in banks’ internal risk
management processes; third, the enhanced mechanisms to encourage
the marketplace to exert external discipline on banks and the
banking sector; and fourth, the necessary greater co-operation among
supervisors across jurisdictions.
Through these channels,
Basel II should remove distortions potentially hindering capital
flows, improve the efficiency of the allocation process, and
increase the stability and resilience of the financial system.
The way I see this improved dynamic “risk-based
efficiency”, as I would call it, is that, given the same situation
of an economy in terms of risk appetite and risk absorption
capacity, the financial system will be able to provide more and
better allocated financing flows, something that may help to
increase the potential growth of the economy, without reducing the
safety and soundness of the system.
All in all the potential
impacts of this new regulatory approach may be profound and
wide-ranging. I would like to explore some of these implications
that have received some attention.
6. How Basel II will
affect the flow of capital across borders.
Let me start reflecting on
how Basel II will affect the flow of capital across borders.
Some observers suggested that the new capital framework’s
heightened sensitivity to risk may reduce the flow of foreign
investment in developing economies, since exposures to those
economies might typically be considered of higher risk.
I believe that, in the short
run, Basel II will not have a material effect on the flow of
capital, whereas in the medium and long term Basel II’s
forward-looking elements will probably take over and higher risk
efficiency will improve the financing of all kinds of economies.
The first part of this
comment, the lack of any short-term material effect on capital
flows, is based on the notion that Basel II seeks to align capital
regulations more closely to banks’ current practices, which today
are already risk-sensitive. Therefore,
it will not change the way that banks actually evaluate risk to
decide whether to invest in emerging market economies.
Yet some observers have
assumed that a more risk-sensitive approach might drive up not just
capital requirements, but also the pricing of credit to emerging
market countries. This argument assumes that regulatory capital
drives individual loan pricing decisions.
However, while regulatory capital is important and may
represent an overall constraint, research and discussions with banks
actually suggest that, when determining the price of a loan, banks
consider all of the economic risks associated with a particular
borrower. It seems that factors such as “economic capital” and
the level of competition are much more influential in individual
loan pricing than regulatory capital.
That finding should be no
surprise to any banker or supervisor – banks that are managing
their risks appropriately are already considering the risks that
they face when they lend to higher-risk borrowers, and thus lower
credit quality is already priced into a loan, even under the
existing less risk-sensitive capital rules today.
Furthermore, there are
additional elements in Basel II that can contribute to alleviating
concerns about the impact on capital flows to emerging markets. Let
me mention the reduction in capital charges for retail lending,
residential mortgages, small and medium enterprises (exposures below
€ 1 million) and well-provisioned past-due loans.
Also, the recognition of credit risk mitigants, such as
collateral and guarantees, is significantly better in the new
framework of Basel II.
If we take a medium or
longer-term perspective, the different channels that I mentioned
before will ensure better access to financial flows for the same
risk. Furthermore, market dynamics may reinforce this process and
those banks that adopt higher standards of risk management and
capital and countries that embrace the new supervisory approach
could be perceived by markets as less risky, resulting in lower risk
premiums and better access to financial markets.
Given the advantages of
Basel II, it may be that the timetable set by the markets for banks
and countries to evolve to Basel II will perhaps be more demanding
than the soft transition that the supervisory community and other
institutions are proposing.
From a different
perspective, I think that what should be of concern to emerging
markets is not just the level of capital flowing into a country, but
also the volatility of the level of capital inflows. Abrupt changes
in capital flows can be just as harmful as lower levels of flows.
Volatility erodes confidence in the future supply of credit,
rendering long-term planning meaningless.
I believe that banks
adopting especially the advanced approaches to credit risk will
increasingly take longer-term views of their international
investments, as stress testing and other requirements will ensure
that they consider how their risks would react to certain changes in
the market environment. More formalised and disciplined risk
assessment processes may provide for early detection of deviations
or mistakes, and that may facilitate making smoother corrections at
an early stage, reducing the probability of sudden changes in
investment decisions. This, in turn, should benefit emerging market
economies by improving the degree of confidence that they can have
in the future level of capital inflows.
This is very much related to
the discussion about procyclicality, an important issue that we at
the Committee have taken up and addressed seriously. In particular,
some have suggested that the ratings-based approaches will drive up
the cost of credit for borrowers precisely at times when its supply
is falling, namely during downturns in the business cycle.
This is a very complex point
and deserves a whole lecture in itself.
Given the time constraints today, I would like just to
summarise my own views. Of
course, I fully respect the different opinions that may exist on
this issue, but in my opinion, there are some elements that make me
think that the concerns over procyclicality are exaggerated.
There is some degree of procyclicality inherent in banking
behaviour. The question that we should consider is whether Basel II,
or any regulation, will unduly exacerbate this behaviour.
Furthermore, it is also important to consider the trend around which
cycles will fluctuate. I think that under Basel II, in the context
of a more efficient and sound financial system, fluctuations will
occur around a superior trend. This superior trend represents a
better relationship between the capacity of the economy to absorb
risks and the ability of the banking system to provide credit.
Furthermore,
one cause of pro-cyclical behaviour is low capitalisation and weak
risk management. Undercapitalised
banks will tend to make abrupt decisions to cut lending when there
is news of a downturn, and banks which have not assessed risks
properly may likewise be forced to react abruptly.
Pillar 2 of Basel II requires banks to have a capital
strategy that takes into consideration the fluctuations of capital
through the cycle and to hold additional buffers of capital that
will help to offset potential problems.
Basel
II’s more forward-looking approach to granting credit introduces
“risk awareness” and “early detection” factors that will
provide additional defence against credit disruptions and
procyclicality. I also believe that when
banks have the right incentives to manage their risks appropriately,
to hold sufficient capital and to improve transparency, the banking
system will become more resilient, more stable and better able to
serve as a source for credit and growth.
Nonetheless, the Committee
recognises that any risk-sensitive capital framework will cause the
minimum capital requirement to fluctuate for the same exposure if a
borrower’s creditworthiness strengthens or weakens. To mitigate
excessively wide swings in capital requirements, the new framework
incorporates a number of elements such as the requirement to use longer time horizons
in the design of internal rating systems and in the average
calculations of key variables, and also the need to carry out stress
tests and conduct calculations in downturn conditions. All these
elements will ensure that bank managers are conscious of how
risk-drivers change through the cycle and in stress conditions, and
that they incorporate these elements into their decision-taking
processes and capital strategies.
Let me add a final comment
to this important issue. It is clear to me that we could also do
more, beyond the strict solvency standards, and study how other
regulations, such as those related to provisioning, can contribute
to reducing pro-cyclicality.
7. Basel
II impact on global competition.
Another broad concern that
the Committee has worked to address is Basel II’s impact on global
competition. In particular, some have asked whether banks that
choose Basel II’s advanced approaches will enjoy benefits over
those that choose simpler approaches or remain on the 1988 Accord.
Basel II reflects also the
existing diversity of banks and jurisdictions and the sense that no
single-policy approach, and no single hard-and-fast rule, could be
applied to all banks of all shapes and sizes. Consequently, the
Basel Committee sought something bolder than a single, universal
rule. The so called “menu approach” of
Basel II offers different alternatives to different kinds of
banks and jurisdictions, but in developing this approach significant
efforts were made to ensure that the level playing field is
maintained.
We should understand that
adopting an advanced approach requires significant investments and
does not automatically reduce a bank’s capital requirements. In a
more risk-sensitive capital framework, capital requirements for an
advanced bank may actually rise relative to the current rules if the
bank’s exposures are actually riskier than the measures under the
1988 Accord would have suggested. Furthermore, some national
supervisors in emerging economies may set higher capital
requirements than implied by Basel I, perhaps even higher than those
implied by Basel II, depending on the risk environment.
The issue of competition
between banks has also come up in the context of competition between
countries. Here, we should remember that Basel II is intended to
help ensure that international competition in banking markets is
driven by the strengths of each bank, rather than by differences in
each country’s rules.
One way that the Committee
has sought to promote a consistent application of the new framework
is by providing detailed requirements where necessary. As I have
already mentioned, these details may add to the appearance of length
and complexity, but a balance is necessary to ensure greater
consistency and a more level playing field.
However, given the need for
a framework which can be adapted to a wide range of circumstances,
co-operation among supervisors is clearly the most important tool in
achieving an appropriate level of consistency. To a large extent,
the need for greater collaboration is a natural result of the
increased level of internationalisation and integration in the
financial sector. We
have seen some structural developments over recent years that
certainly pose challenges for both home and host supervisors alike,
such as the emergence of locally significant - and
systemically important - subsidiaries of foreign banks. Also, a
local unit in a foreign country may be systemically important for
the group.
But I think that, at least
in some areas, Basel II will act as a kind of catalyst for action.
Under the new framework, internationally active banks will
use systems whose recognition and on-going validation will
indisputably require vastly increased collaboration among
supervisors. Co-operation is a key word, but so too are convergence,
communication and confidence. Communication is vital not only
between supervisors or between supervisors and the industry but
also, and very importantly at this stage, within banking groups so
that all units are aware and understand the implementation plan.
Additional co-operation and
communication among supervisors will enhance confidence, reliance
and convergence of supervisory practices.
And some reliance and convergence will be necessary if we
want to avoid redundant work, inefficiencies in the use of
supervisory resources and an excessive burden for the industry.
We are placing great emphasis on all these issues in our
“Accord Implementation Group”, which is working together with
many supervisors on what we call “real” case studies, and which
is making good progress.
8. Conclusion
Let me take a few moments to
draw some conclusions. What
I have tried to do today is to highlight the anticipatory and
forward-looking elements of Basel II.
But, as with many things, I think that the real value of
Basel II will be best evaluated with the benefit of perspective.
This brings me back to our author of 2046.
It may be that Basel II does
not cover all the areas and refinements that are necessary to
complete the framework for financial stability. It may be that Basel
II raises new issues and requires a lot of work to be implemented.
However, it is my view that Basel II cannot be assessed in a static
way.
I believe that we will need
some time to be able to fully judge the real benefits of Basel II.
In my opinion, the main strengths of the framework do not come from
its quantitative regulatory requirements, although these are
certainly important. Neither do I believe that the most fundamental
aspect is when exactly the new framework will be implemented in
different countries. This will just be a transitional issue.
One of the essential
strengths of the incentive-based approach of Basel II is the dynamic
way in which it will contribute to financial stability by promoting
risk sensitivity and strong risk management practices across banks,
reinforcing market discipline and enhancing cooperation. These are
key elements, because, in the end, no regulation in itself can
prevent problems in badly-managed banks.
And
Basel II represents a tremendous opportunity for banks themselves.
By stimulating them to upgrade and improve their systems, business
models, capital strategies, risk management systems and disclosure
standards, Basel II should improve their overall efficiency and
ability to compete globally.
It is my view that, if
supervisors and banks in 2046 look back at the evolution of
financial regulation over the years, they may well think in terms of
"before Basel II" and "after Basel II".
