The Spanish government agreed to open the books of Spanish regional governments and the regional savings banks to reduce concern in financial markets about Spain's debt. Spain's government debt is 53.2% of GDP in 2009, which is lower than Greece at 127%, Italy at 116%, Portugal at 76%, Ireland at 65%, and Germany at 73%. Spain's problem is the a large amount of private debt accumulated during15 years, in the low interest rate environment after joining the eurozone. Joining the euro sent interest rates in Spain down because it removed the risk of devaluation. The government was restrained by the Maastricht treaty criteria but private investors and regional banks could borrow freely, and they borrowed extensively, with money going into home building and construction. The fear is that the Spanish government will end up taking on much of this debt. The other problem is that Spain needs to refinance much of that debt in 2011, at a time when investors are nervous about eurozone debt. Spain's central government will need to raise 170 billion euros in 2011, regional governments another 30 billion euros, and Spanish banks another 90 billion euros. The government has set up a special facility for Spanish banks to draw on of 99 billion euros....
