523 European banks borrowed 489 billion euros from the European Central Bank on Dec. 21, 2011, under the newly created Long Term Financing Operation of the ECB. This is designed to meet the financing needs of European banks which are shutoff from normal financing of selling unsecured bonds to private investors because of market anxiety. Much of this is for replacing other outstanding ECB loans, with analysts estimating about 190 billion euros of new liquidity being injected into the banking system. This also has the effect of reducing the borrowing rates for government bonds. In Spain the government sold 5.6 billion euros of government bonds at an auction on Dec. 20, 2011, with the interest rates dropping from 5.7% a month earlier to 1.7%. Small and midsize banks in Spain helped surging demand by buying the bonds to use as collateral for three year loans from the ECB at 1%.
