He announced a new goal for the program to support financial markets, which supply consumer credit in such areas as credit card debt, auto loans and student loans.
Paulson said that 40 percent of U.S. consumer credit is provided through selling securities that are backed by pools of auto loans and other such debt. He said these markets need support.
"This market, which is vital for lending and growth, has for all practical purposes ground to a halt," Paulson said.
The administration decided that using billions of dollars to buy troubled assets of financial institutions at the current time was "not the most effective way" to use the $700 billion bailout package, he said.
The announcement marked a major shift for the administration which had talked only about purchasing troubled assets as it lobbied Congress to pass the massive bailout bill.
Paulson said the administration is exploring other options, including injecting more capital into banks on a matching basis, in which government funds would be supplied to banks that were able to raise capital on their own.
