"An ongoing need still clearly exists" for the program, which also is aimed at making sure loans flow to the troubled commercial real estate market, Bernanke said in brief remarks to a conference here sponsored by the Congressional Black Caucus Foundation.
The Term Asset-Backed Securities Loan Facility goes to the heart of efforts by the Fed and Obama administration to get credit flowing more normally again, a key ingredient to a lasting economic recovery. The Fed has extended the TALF - which has the potential to generate up to a $1 trillion in lending for households and businesses - into next year. It was originally set to expire at the end of this year.
Under the program, which got off to a slow start in March, the Fed provides loans to investors. They use the money to buy newly issued securities backed by auto and student loans, credit cards, business equipment, commercial real estate and loans guaranteed by the Small Business Administration.
In the first phase, the Fed was making $200 billion available for the loans. However, investors have requested far less than that.
Still, Bernanke said the program is responsible for indirectly financing nearly 3 million loans to households - excluding credit cards - and nearly 400,000 loans to small business.
The program has attracted 121 borrowers so far, including investors of all sizes, he said.
But analysts say it is still difficult for many consumers to secure loans, one of the forces threatening to restrain the budding economic recovery.
In fielding questions after his remarks, Bernanke said the TALF program helped drive down rates on auto loans, which have "improved considerably."
Bernanke also said he was "hopeful the situation in the auto industry is going to improve." Auto sales - and production - have gotten a lift from the now-defunct government Cash for Clunkers program, where people got a rebate of up to $4,500 to buy new cars and trade in old gas guzzlers.
The Fed chief also pledged to reach out even more to minority-owned companies to make sure they are being included and helped by various government emergency lending programs.
