Unemployment in the 16 countries that use the euro spiked to a ten-year high in May, reinforcing concerns any recovery will take time with so many people out of work, according to AP. Eurostat, the statistics office of the EU, said Thursday the seasonally-adjusted unemployment rate for the euro zone in May stood at 9.5 percent, up from April's 9.3 percent. The increase was expected in the markets in light of the ongoing fall in output across Europe _ in the first quarter of 2009, the euro zone economy saw output plunge by 2.5 percent as the global recession hit the industrial sector in particular. The unemployment rate was at its highest level since May 1999. Spain is the euro zone's biggest casualty. Its jobless rate rose to 18.7 percent in May from 18 percent in April. The lowest unemployment rate in the euro zone was in the Netherlands where only 3.2 percent of the working population were without a job in May, and Austria, where only 4.3 percent were jobless. The unemployment rate in Germany, Europe's biggest economy, was unchanged at 7.7 percent in May. Unemployment is a lagging indicator, so the number of jobless will likely continue to rise for a while even when the recession officially ends. Recent economic releases have stoked hopes that the euro zone may start to see some sort of recovery towards the end of the year but that high unemployment levels will continue to weigh on consumption and sentiment. The unemployment news comes just hours ahead of the European Central Bank's latest interest rate decision. Though the rate-setting governing council is set to keep its benchmark rate unchanged at the record low of 1 percent, its president Jean-Claude Trichet is expected to note the recent improving economic signals though maintaining his view that recovery will take time. Including the eleven countries that don't use the euro but are in the EU, such as Britain and Sweden, the unemployment rate rose to 8.9 percent in May from 8.7 percent in the previous month. May's rate was the highest since June 2005. The EU-wide rate has been swelled by the Baltic countries, which are in a deep recession following the collapse of debt-fueled economic boom. Latvia, whose economy slumped by a staggering 18 percent year-on-year in the first quarter, saw its unemployment rate, climb to 16.3 percent in May from 15.3 percent in April.
