Amid decent signs of economic amelioration in the 17-nation area that has single currency in circulation, the latest inflation report is supporting the case for the ECB to keep borrowing costs at current level to stimulate the economy. European statistics office Eurostat said consumer prices stood at the annual rate of 1.1% in September, down from 1.3% recorded in August, and below analysts' projection, who expected the same figure as a month earlier. This is the lowest level since February 2010, which is far below the ECB's target of slightly under 2%. September's drop was mainly due to a decline in energy prices, which slid 0.9% on the year, while costs of food, alcohol and tobacco slowed significantly to 2.6% over the same period.
