Updated at 5.46pm: Rises in rents and oil prices helped push Hong Kong?s inflation up to 1.6 per cent in September compared with a year earlier, government figures released on Friday showed. The Consumer Price Index rise during September was larger than the 1.4 per cent increase recorded in August, figures from the Census and Statistics Department showed. The department said this was mainly caused by a rise in housing rents and oil prices ? which had increased fuel charges. In September, electricity, gas and water charges jumped 4.1 per cent year on year; food prices rose 2.4 per cent and transport climbed 2.1 per cent. For the first nine months of this year, consumer prices rose 0.9 per cent compared with the same period last year. A government spokesman predicted inflation would keep rising in Hong Kong. ?Looking ahead, consumer price inflation is expected to move up further, along with the gradual rise-back in private housing rentals and in business costs and with the further pass-through of higher oil prices to the retail level.? But he said overall price pressure was likely to remain moderate until year-end. Last year, Hong Kong emerged from 68 months of deflation.
