NEW YORK, Dec 3 (Reuters) - A U.S. appeals court on Tuesday handed President Donald Trump another defeat in his bid to keep his financial records secret, directing Deutsche Bank AG and Capital One Financial Corp to comply with subpoenas from congressional Democrats demanding the material.

A three-judge panel of the Manhattan-based 2nd U.S. Circuit Court of Appeals ruled 2-1 against Trump's bid to block two House of Representatives committees from enforcing subpoenas issued in April to the two banks seeking the documents. Trump is expected to appeal the case to the U.S. Supreme Court.

The 2nd Circuit rejected Trump's arguments that Congress lacked a valid purpose for seeking his records and that disclosure of the material would compromise his and his family's privacy and distract the Republican president from his duties.

The material sought by the committees include records of accounts, transactions and investments linked to Trump, his three oldest children, their immediate family members and several Trump Organization entities.

"The Committees' interests in pursuing their constitutional legislative function is a far more significant public interest than whatever public interest inheres in avoiding the risk of a Chief Executive's distraction arising from disclosure of documents reflecting his private financial transactions," Judge Jon Newman wrote in the ruling.

Trump had sued the two banks in an effort to prevent the disclosure of his financial records. U.S. District Judge Edgardo Ramos ruled in May that the subpoenas could be enforced, prompting Trump to appeal.

"We believe the subpoenas at issue are not valid," said Jay Sekulow, a lawyer for Trump. "In light of the 2nd Circuit decision, we are evaluating our next options including seeking review at the Supreme Court of the United States."

The Supreme Court's 5-4 conservative majority includes two justices appointed by Trump.

Democratic House of Representatives Speaker Nancy Pelosi called the ruling "another victory for the rule of law, our constitution and our American democracy."

Leaders of the two House panels that issued the subpoenas - Maxine Waters of the Financial Services Committee and Adam Schiff of the Intelligence Committee - said in a statement the ruling "ensures that a significant amount of the materials sought by our committees will continue to be produced."
