Retail and institutional deposits at Greek banks fell 19 percent in the past year and almost 40 percent at Irish lenders in 18 months. In Portugal, where banks raised the interest rates they pay savers, non-residents have reduced deposits by 19 percent since March 2010. In Germany, deposits by financial institutions, which account for one-third the total, declined 12 percent over the same period and 24 percent since the September 2008 collapse of Lehman Brothers Holdings Inc., ECB figures show. In France, where the erosion started last year, the same type of deposits, which make up half the total, are down 6 percent since June 2010. They have fallen 14 percent since May 2010 at Spanish banks, where they account for one-fifth of the total.
