The White House yesterday proposed the most far-ranging overhaul of the financial regulatory system since the stock market crash of 1929 and the ensuing Great Depression.

The plan would change how the government regulates thousands of businesses from the biggest US banks and investment houses down to the local insurance agent and mortgage broker.

Treasury Secretary Henry Paulson unveiled the 218-page plan in a speech in Treasury's ornate Cash Room. He declared that a strong financial system was important not just for Wall Street but also for working Americans.

The administration's plan was already drawing criticism from Democrats that it does not go far enough to deal with abuses in mortgage lending and securities trading that were exposed by the current credit crisis.

The plan would give the Federal Reserve more power to protect the stability of the entire financial system while merging day-to-day bank supervision into one agency, down from five at present.

It also would create one super agency in charge of business conduct and consumer protection, performing many of the functions of the current Securities and Exchange Commission.
