The drop in the CPI was in line with the median forecast by 10 economists surveyed by Reuters. In November, the index had fallen 1.7%.

December's decline was driven by an 8.4% drop in the transport sector, as well as lower housing, water, electricity, gas and other fuel prices, the Statistics Department said in a statement.
