U.S. President Barack Obama on Tuesday welcomed the repayments to the government of $68 billion in bank bailout funds but said the problems in the financial markets were not over yet.

This is not a sign that our troubles are over; far from it, Obama said in prepared remarks. The financial crisis this administration inherited is still creating painful challenges for businesses and families alike. But it is a positive sign.

He said that it was crucial that the country learn lessons from the worst financial crisis since the Great Depression and to ensure market players do not take reckless risk.
