The Federal Reserve Bank Board approved Capital One Financial's application to become a bank holding company.

The nation's sixth-largest credit card company, based in McLean, said the Fed's decision allows it to diversify from credit cards and its other businesses, which include auto loans, installment loans and small-business loans. As a bank, it will have access to low-cost consumer deposits, a spokesperson said.

The company will have to restructure some of its operations, such as venture capital and insurance, to conform to bank holding company regulations.

Capital One, founded in 1995, has been talking about buying a bank for several years, and a spokesman says that with the Fed approval it is likely to do so now, since banking is a "natural extension" of its diversification strategy.

The Fed said Capital One is well capitalized, with consolidated assets of $39.8 billion, which makes it the second-largest deposit-holder in Virginia. It will remain well-capitalized after the conversion, the Fed said in a statement. The company had 46.7 million managed accounts and $71.8 billion in managed loans outstanding as of March 31.
