NEW YORK (

TheStreet

) --

Citigroup

(C) - Get Report

was among the weak performers in the financial sector Thursday following reports the bank was considering a plan to pare back its retail banking operations.

Citigroup

shares opened higher but were lately down after the

Wall Street Journal

reported that the bank, which is 34% owned by the U.S. government, would narrow the focus of its U.S. branch network and plans to limit its overall consumer lending in the U.S. primarily to credit cards and "jumbo" mortgages.

The report, citing people familiar with the matter, said Citigroup would concentrate its branch network in six major metropolitan areas, including New York, Los Angeles, San Francisco, Chicago, Washington and Miami. Citi's proposal also includes selling branches in Texas and a look at whether it will continue to maintain a presence in Boston and Philadelphia, the

Journal

reported.

Citigroup was lower by 9 cents, or 2%, to close at at $4.43.

Other bank stocks also finished lower after the

Federal Reserve

announced plans to pare back two emergency-lending programs. The central bank said it will reduce its 28-day term-auction facility to $25 billion from $75 billion. The Fed also offered a schedule for unwinding its 84-day term-auction facility into January 2010.

Financial stocks were also rattled by the National Association of Realtors' report that existing -home sales fell 2.7% in August. Economists polled by

Reuters

had expected existing-home sales to rise in August and build on gains from July.

and BofA in revamping overdraft fees for customers. The bank said it is eliminating fees for Wells and Wachovia customers when they overdraw their accounts by $5 or less. Wells also will not charge customers more than four overdraft fees per day, the company said.

Already, JPMorgan said starting in the first quarter of 2010 it will make overdraft protection opt-in for all customers. Bank of America said starting next month it won't charge overdraft fees when a customer's account is overdrawn by less than $10 for one day.
