NEW YORK, Sept 29 (Reuters) - U.S. stocks slid on Monday after Wachovia Corp <WB.N> became the latest major U.S. bank to succumb to the global credit crisis, increasing fears about the banking sector's stability as lawmakers geared up to vote on a $700 billion financial bailout plan.
As U.S. lawmakers met in Washington, analysts questioned whether the rescue plan was sufficient and whether it would come soon enough to shelter the economy and stem the financial turmoil that was spreading around the world.
European authorities were forced over the weekend to step in and rescue a slew of European banks, while U.S. regional bank Wachovia sold most of its assets to Citigroup <C.N> in a deal brokered by the Federal Deposit Insurance Corp. Global money markets remained frozen, even as central banks, including the Federal Reserve, pumped cash into world markets in an attempt to boost liquidity.
"A lot of people are saying this bailout is not enough, that it is at best a partial solution. Fear and pessimism are on the rise, especially given what happened over the weekend with the European banks and most significantly with Wachovia," said Eric Kuby, chief investment officer of North Star Investment Management Corp., in Chicago.
"Even if there was to be a relief rally, we first have to get a vote on the bailout. We started Monday with more fear than when we left on Friday."
The Nasdaq fell more than 4 percent, led by Apple Inc <AAPL.O>. The stock of the iPod and iPhone maker tumbled as much as 17.5 percent on concerns the company will suffer as the economy slows.

The Nasdaq Composite Index < > was down 99.03 points, or 4.54 percent, at 2,084.31.Shares of Bank of America Corp <BAC.N> led financials down in the S&P 500, with a drop of nearly 6 percent, while American Express <AXP.N> was a drag on the Dow, with a slide of more than 6 percent. The S&P financial index <.GSPF> fell 5.2 percent. Regional banks' shares fell sharply, as investors tried to work out who could be the next victim of the credit crisis.
Apple Inc <AAPL.O> fell 14 percent to $110.21 after several brokerages slashed their recommendations on the tech bellwether.
Energy companies' stocks fell as U.S. front-month crude <CLc1> dropped more than $8 to below $99 a barrel, as the financial turmoil spread to Europe, fueling concerns about the global economy and lower demand.
Shares of Exxon Mobil <XOM.N> fell 2.4 percent to $78.70, while the S&P energy index <.GSPE> tumbled 6.2 percent.
"There's a monster amount of fear out there. This is global contagion. It's no longer just the United States," said Joe Saluzzi, co-manager of trading at Themis Trading in Chatham, New Jersey.
In Europe, the British government took over troubled mortgage lender Bradford & Bingley <BB.L> and three European governments partially nationalized banking and insurance group Fortis <FOR.BR><FOR.AS>.
