An internal IMF document that estimates Europe's banks are short of capital by $273 billion. IMF managing director, Christine Lagarde, tries to downplay the report by saying this is not from a stress test that the IMF conducts. In August, Lagarde, called for an "urgent recapitalization" of European banks. As France's finance minister, Lagarde, steadfastly insisted French banks were well capitalized. France worked hard to prevent requirements for significant capital reserves under the Basel III rules. The higher capital requirements were supported by the U.S.. Simon Johnson said in his blog, that as long as European banks had inadequate capital to act as a buffer against losses, European countries had no safe route for restructuring their debts.
