Annualized eurozone inflation fell to 0.5 per cent in March, Wednesday, amid fears that the currency bloc could slip into deflation, dpa quated the European Union's statistics office Eurostat as confirming. The figure, backing up an earlier estimate, keeps consumer prices in what European Central Bank (ECB) chief Mario Draghi has called the "danger zone" of an inflation rate below 1 per cent. On Saturday, Draghi assured the International Monetary Fund that the bank was prepared to use "unconventional instruments" to tackle low inflation. The Washington-based crisis lender has estimated that the risk of deflation in the eurozone stands at 20 per cent.
