The European Central Bank said improving sentiment toward the Euro area spurred demand for the region's debt, even as the Euro's share in global foreign-exchange reserves fell. Foreign demand for Euro area portfolio investments rose to 3.7% of GDP in 2013 from 3% a year earlier, reaching the highest level since the onset of the financial crisis. The capital inflows indicate an improving economic recovery and a rebalancing of investments away from emerging market securities. Sustained interest in the region's debt pushed the single currency 7% up against a basket of 39 currencies last year, the second largest appreciation since 1999. Policy makers have been concerned over the Euro's strength and its impact on the fragile economic recovery, and released a new package of measures designed to boost lending, growth and inflation in June.
