NEW YORK, Oct 28 (Reuters) - Investors snapped up stocks that had plunged during the worst October on record as a rally in equities marched across the world on Tuesday and dimmed the safe-haven appeal of government debt, the dollar and the yen.
Investors put aside any fears they may have of a deep worldwide recession even after U.S. consumer confidence fell to an all-time low in October, driving the Dow industrials up more than 3 percent.
The Dow had shed almost 25 percent in October as of Monday, and all U.S. equity markets, as measured by the Wilshire 5000 index, have lost about $4 trillion in value during the month.
A recovery in Asian equity markets overnight and a rise in European shares sowed optimism, along with signs of a further thaw in the credit markets. The rates banks charge each other to borrow funds in euros, the dollar and sterling fell.
Oil retreated from session highs, at first tracking a brief late-morning decline in U.S. stock markets and later hovering at Wednesday's U.S. settlement of $63.22 a barrel.
The yen fell across the board while the dollar retreated against the euro as the recovery in global stocks prompted investors to lock in recent steep gains in the dollar and yen.
European shares snapped a five-day losing streak, riding a huge surge in Volkswagen <VOWG.DE> shares, but banking losses took the edge off the rally's early stellar gains.
Downtrodden sectors such as technology, financials and energy led the U.S. stock advances, a day after a late slide sent equity indexes to their lowest levels in 5-1/2 years.
Shares of Apple Inc <AAPL.O> , maker of the iPhone and the iPod, were a top boost to the Nasdaq, while Exxon Mobil <XOM.N> led the Dow's climb after rival BP Plc <BP.L> posted a record profit.
Investors, however, remained wary about the economy's health, causing some to sell into any apparent strength.
"Overseas markets rebounded and I think that was a catalyst for us to open up stronger," said Alan Lancz, president of Alan B. Lancz & Associates Inc, an investment advisory firm based in Toledo, Ohio. "There's some nibbling in. But I wouldn't chase any rallies. I'd use them to reduce risk."

VW briefly became the world's biggest company by market value. Porsche rose 9.9 percent. [
]Banks stocks, however, were weak. Shares in French bank Societe Generale <SOGN.PA> slumped for a second day in a row, down 12.3 percent as traders cited a possible exposure to the share price surge at Volkswagen.
Moves in currency markets were technical, analysts said, as there has been no major catalyst to change the perspective on risk-taking, even as ongoing unwinding of leveraged trades away from risky assets remained entrenched.
"The FX market is still completely driven by equities," said Vassili Serebriakov, senior currency strategist at Wells Fargo in New York.
"I don't think there's any major reason to expect that this fall in the yen and dollar would be pronounced and long-lasting. Economic fundamentals are still weak all over the world," he said.
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.55 percent at 87.675. Against the yen, the dollar <JPY=> rose 3.65 percent at 96.18.

U.S. Treasury and euro zone debt prices fell as equity markets rose, dimming government bonds' safe-haven appeal.
