NEW YORK - Wall Street is plunging, with the Dow Jones industrials down more than 500 points amid growing fears that the credit crisis is spreading around the world.

Investors are realizing that the Bush administration's $700 billion rescue plan won't work quickly to unfreeze credit markets, and many banks are still having difficulty gaining access to cash. European governments also took steps over the weekend to limit the damage from the growing global financial crisis.

The Federal Reserve also took fresh steps to help ease credit markets Monday.

The Dow is down more than 570 points at the 9,747 level.

NEW YORK (AP) - Wall Street tumbled Monday, joining a selloff around the world as fears grew that the financial crisis will cascade through economies globally despite bailout efforts by the U.S. and other governments. The Dow Jones industrials skidded more than 400 points and fell below 10,000 for the first time in four years, while the credit markets remained under strain.

The markets have come to the sobering realization that the Bush administration's $700 billion rescue plan won't work quickly to unfreeze the credit markets, and that many banks are still having difficulty gaining access to cash. That's caused investors to exit stocks and move money into the relative safety of government debt.

Over the weekend, governments across Europe rushed to prop up failing banks. The German government and financial industry agreed on a $68 billion bailout for commercial-property lender Hypo Real Estate Holding AG, while France's BNP Paribas agreed to acquire a 75 percent stake in Fortis's Belgium bank after a government rescue failed.

The governments of Germany, Ireland and Greece also said they would guarantee bank deposits.

The Federal Reserve also took fresh steps to help ease seized-up credit markets. The central bank said Monday it will begin paying interest on commercial banks' reserves and will expand its loan program to squeezed banks.

Investors took a bleak view of the future, seeing no end to the crisis in the near term. But analysts were more optimistic.

"These programs are going to be effective I believe," said Rob Lutts, chief investment officer at Cabot Money Management.
