However, hedge funds, private equity firms and investment banks are subject to substantially less regulation.

The credit crisis that has rocked Wall Street and made it hard for ordinary Americans to obtain credit has highlighted the discrepancy in regulation efforts.

But Henry Paulson, the US treasury secretary who has led the effort to rewrite regulations, rejects accusations that the current system created the problems.

"I do not believe it is fair or accurate to blame our regulatory structure for the current turmoil," he said according to a draft of a speech to be given on Monday.

Sweeping overhaul

The proposed changes would represent the most sweeping overhaul of the country's financial regulation since the Great Depression of the 1930s.

Christopher Dodd, chairman of the Senate banking, housing and urban affairs committee said in a statement that the recommendations deserved careful consideration.

But the Democrat senator said that he believed they "would do little if anything to alleviate the current crisis".
