WASHINGTON — Lending through the Federal Reserve Board's discount window fell 3.5% during the past week to $115.2 billion.
Traditional borrowing by commercial banks declined 3%, to $46.9 billion, and there was $60 million of loans to unhealthy banks, down slightly from $62 million a week earlier.
Loans to investment banks were down 22.4%, to $10.4 billion.
The Fed said it had extended $45.5 billion by Wednesday through the discount window to support American International Group Inc. The central bank also has a limited liability corporation designed to help the insurance giant. Loans there were valued at $18.3 billion.
Lending against asset-backed commercial paper held by money market mutual funds was of 45.1%, to $2 billion. The Fed has yet to make loans to another limited-liability corporation that will buy unsecured assets held by money markets.
Separate from the discount window, the Fed said it had purchased $238.4 billion in commercial paper by Wednesday, down 5% from a week earlier.
Meanwhile, the Federal Reserve Bank of New York purchased $30.4 billion of mortgage-backed securities from the government-sponsored enterprises during the past week: $25.5 billion from Fannie Mae; $3.2 billion from Ginnie Mae and $1.8 billion from Freddie Mac. Total purchases were down 59.3% from a week earlier.
