During the November 2011 to February 2012 period Spanish banks increased holdings of government bonds by 68 billion euros, and Italian banks by 54 billion euros under the ECB's Long Term Financing Operation. That program helped to lower bond yields of the two countries for the 1st quarter of 2012. With Spain's economy facing more austerity measures at a time of 23% unemployment, bond yields have moved back up for Spain in April 2012. The increased holdings of government bonds by Spanish banks increases risks at a time when banks in Spain have not increased lending in the economy and hold a large number of bad mortgages in the country's housing bust.
