Lender of Last Resort
There are advantages in central banks acting as both Lender of Last Resort and banking supervisor.
The
financial turmoil in the developed markets in Europe and America
caused by the US sub-prime mortgage problem will, in the coming
months, stimulate a lot of discussion over what went wrong, the
lessons to be learnt, and the remedies. This will likely be a
discussion of global interest, even though contagion to the emerging
markets has been limited up to now. There are, I am sure, valuable
lessons to be learnt by the emerging markets, particularly about
what not to do, as they continue to embark on financial
liberalisation and financial innovation.
Inevitably the discussion will also focus on the roles of central
banks and supervisory authorities in the maintenance of financial
stability, and how best this important work should be organised,
including the pros and cons of institutional separation of the
central bank and the banking supervisor. The recent trend, if one
can be discerned, is for separation, with some prominent examples of
this taking place in the developed markets, although the arguments
for doing so have not been convincingly articulated. There is a
lingering impression in those jurisdictions that have gone for
separation and among observers interested in the governance
arrangements of central banks and supervisory authorities that the
trend has been very much coloured, if not initiated, by political
motives.
Whether or not a central bank is also the banking supervisor, it is
clear that the role of Lender of Last Resort is for the central
bank. It is inevitable that occasional stresses in the financial
system will lead to a shortage of liquidity to an extent beyond the
ability of the banks to handle on their own. The central bank, as
the only institution able to create liquidity in the banking system,
has an important role to play as Lender of Last Resort, particularly
if the liquidity problem threatens systemic stability. Such
systemic liquidity problems, if allowed to persist could lead to a
general tightening of credit that would have adverse implications
for the economy. However, the role of Lender of Last Resort entails
significant moral hazard because the central bank might be seen as
too willing to underwrite the banking system and bail out banks that
are not as well run as others, indirectly encouraging imprudent
practices.
There is no internationally accepted approach to this dilemma
because the banking systems in different jurisdictions have very
different characteristics. Countries that rely on their banking
systems to meet the bulk, if not all, of the financial
intermediation needs of their economies will understandably have
different attitudes to those with diversified and integrated
channels of financial intermediation. In any case, I think the
central bank should play the role of Lender of Last Resort as
transparently as possible. Transparency has a useful tranquillising
effect on those, including of course depositors, who may, for one
reason or another, have worries about the banking system or
individual banks. Readers may be aware of our very clear stance on
the role of the Hong Kong Monetary Authority as Lender of Last
Resort and how we discharge that role. This is articulated in a
policy statement published in June 1999. It sets out the
conditions for receiving Lender-of-Last-Resort support, the
instruments that can be used and other operational details.
I
also think that there is a need for the central bank to have a
mechanism to monitor closely the financial positions of individual
banks, if only so that it can decide quickly whether
Lender-of-Last-Resort support is justified. It is essential for the
central bank to act quickly when a liquidity or a banking crisis
looms to contain it, or if possible nip it in the bud. There may
even be a need for the Lender of Last Resort to develop standing
arrangements with individual banks to maintain maximum readiness. I
think this is best achieved when the central bank is also the
banking supervisor. The flow of information within one organisation
is much smoother than that between two, particularly if they operate
under different legal frameworks, where provisions for central-bank
and banking-supervisor independence may represent barriers to the
effective and timely flow of vital information.
