WASHINGTON — The Federal Reserve plans to release documents on Thursday identifying banks that received Fed loans to survive the financial crisis.

The central bank is being forced to take the action because commercial banks had lost a court battle to keep the information private.

During the crisis, the Fed had argued that releasing the names of banks that drew the emergency loans could cause a run on them, defeating the purpose of the program.

At the height of the financial crisis in the fall of 2008, the Fed loaned as much as $110 billion through its “discount” loan window.

The Fed has long acted as a lender of last resort, offering commercial banks loans through its discount window when they couldn’t obtain financing elsewhere. The Fed has kept secret the identities of such borrowers.

During the crisis, the Fed temporarily extended the emergency loan program to investment houses. The names of those borrowers, however, were released in early December, when the Fed also revealed details about all of its crisis-lending programs – except for commercial banks.
