Annual inflation in the eurozone remained stuck below zero in March, defying analysts' forecasts and the European Central Bank's efforts to boost consumer price pressures in the 19-member currency bloc, dpa reported. The change in consumer prices inched up to minus 0.1 per cent in March from minus 0.2 per cent, according to the preliminary estimate released on Thursday by the European Union's statistics office Eurostat. Analysts had forecast a rise to zero in the March inflation rate. The release of the latest inflation data came after the ECB unveiled earlier this month a package of new monetary measures aimed at heading off the threat of deflation in the eurozone and firing up the region's sluggish economy.
