WASHINGTON - A commission created by Congress to look into causes of the financial crisis will question the chief executives of Goldman Sachs Group Inc, JPMorgan Chase & Co, Morgan Stanley and other big banks at its first public hearing next month.

The Financial Crisis Inquiry Commission said on Wednesday it may also hear from Brian Moynihan, the new top executive at Bank of America Corp, at its hearing on January 13-14.

Lloyd Blankfein, Jamie Dimon and John Mack, who head Goldman Sachs, JPMorgan and Morgan Stanley, respectively, have already confirmed they will testify at the hearing.

The 10-member panel will hold hearings throughout 2010 -- a period in which the Senate will be debating financial regulatory changes. The House of Representatives on December 11 approved a comprehensive bill to tighten government oversight of the financial industry.

The Financial Crisis Inquiry Commission is required to report its findings to Congress and President Barack Obama by December 15, 2010.

The panel's chairman, former California Treasurer Phil Angelides, told Reuters in September that former Treasury Secretary Henry Paulson and executives from housing finance companies Fannie Mae and Freddie Mac, and insurer American International Group might be among witnesses eventually called to testify about the crisis that shook global banks and froze credit markets.

Angelides, a Democrat, said the panel would also look at credit rating agencies and regulators.
