The Census and Statistics Department (C&SD) released today (October 23) the Consumer Price Index (CPI) figures for September 2018. According to the Composite CPI, overall consumer prices rose by 2.7% in September 2018 over the same month a year earlier, larger than the corresponding increase (2.3%) in August 2018. Netting out the effects of all Government's one-off relief measures, the year-on-year rate of increase in the Composite CPI (i.e. the underlying inflation rate) in September 2018 was 3.1%. This increase was also larger than that in August 2018 (2.6%), mainly due to the increases in school fees and the upward adjustment in public housing rentals.

     On a seasonally adjusted basis, the average monthly rate of increase in the Composite CPI for the 3-month period from July to September 2018 was 0.2%, the same as that for the 3-month period from June to August 2018. Netting out the effects of all Government's one-off relief measures, the average monthly rate of increase in the Composite CPI for the 3-month period from July to September 2018 was 0.2%, the same as that for the 3-month period from June to August 2018.

     Analysed by sub-index, the year-on-year rates of increase in the CPI(A), CPI(B) and CPI(C) were 3.3%, 2.5% and 2.4% respectively in September 2018, as compared to 2.5%, 2.2% and 2.0% respectively in August 2018. Netting out the effects of all Government's one-off relief measures, the year-on-year rates of increase in the CPI(A), CPI(B) and CPI(C) were 3.6%, 2.9% and 2.7% respectively in September 2018, as compared to 2.8%, 2.6% and 2.3% respectively in August 2018.

     On a seasonally adjusted basis, for the 3-month period from July to September 2018, the average monthly rates of increase in the seasonally adjusted CPI(A), CPI(B) and CPI(C) were 0.3%, 0.1% and 0.1% respectively. The corresponding rates of increase for the 3-month period from June to August 2018 were 0.2%, 0.2% and 0.1% respectively. Netting out the effects of all Government's one-off relief measures, the corresponding average monthly rates of increase in the seasonally adjusted CPI(A), CPI(B) and CPI(C) for the 3-month period from July to September 2018 were 0.3%, 0.1% and 0.1% respectively, and the corresponding rates of increase for the 3-month period from June to August 2018 were 0.2%, 0.2% and 0.1% respectively.

     Amongst the various CPI components, year-on-year increases in prices were recorded in September 2018 for food (excluding meals bought away from home) (5.1% in both the Composite CPI and CPI(A)); electricity, gas and water (3.8% in the Composite CPI and 4.2% in the CPI(A)); housing (2.9% in the Composite CPI and 4.4% in the CPI(A)); miscellaneous services (2.9% in the Composite CPI and 1.7% in the CPI(A)); meals bought away from home (2.8% in both the Composite CPI and CPI(A)); clothing and footwear (2.5% in the Composite CPI and 3.1% in the CPI(A)); alcoholic drinks and tobacco (2.2% in the Composite CPI and 2.3% in the CPI(A)); miscellaneous goods (1.6% in the Composite CPI and 2.0% in the CPI(A)) and transport (1.3% in the Composite CPI and 1.1% in the CPI(A)).

     On the other hand, year-on-year decrease in prices was recorded in September 2018 for durable goods (-1.8% in the Composite CPI and -1.7% in the CPI(A)). 

     Taking the first 9 months of 2018 together, the Composite CPI rose by 2.3% over a year earlier. The corresponding increases in the CPI(A), CPI(B) and CPI(C) were 2.6%, 2.3% and 2.2% respectively. Netting out the effects of all Government's one-off relief measures, the Composite CPI, CPI(A), CPI(B) and CPI(C) rose by 2.5%, 2.8%, 2.5% and 2.4% respectively in the first 9 months of 2018 over a year earlier.

     In the third quarter of 2018, the Composite CPI rose by 2.5% over a year earlier, while the CPI(A), CPI(B) and CPI(C) rose by 2.8%, 2.4% and 2.2% respectively.  The corresponding increases after netting out the effects of all Government's one-off relief measures were 2.8%, 3.1%, 2.8% and 2.5% respectively.

     For the 12 months ended September 2018, the Composite CPI was on average 2.2% higher than that in the preceding 12-month period. The respective increases in the CPI(A), CPI(B) and CPI(C) were 2.3%, 2.1% and 2.1% respectively. The corresponding increases after netting out the effects of all Government's one-off relief measures were 2.3%, 2.5%, 2.3% and 2.2% respectively. 

Commentary

     A Government spokesman said that the underlying inflation rate went up to 3.1% in September, mainly on account of special factors including the upward adjustment in public housing rentals and increase in school fees as the effects of the government subsidy schemes introduced a year earlier dissipated.

     Looking ahead, the inflation rate may still be subject to some mild upward pressure in the rest of the year, as local costs have increased along with the sustained economic expansion, and as the earlier rises in fresh-letting residential rentals would also continue to feed through. The Government will monitor the situation closely, particularly the impact on the lower-income people.
