* Global stocks in rout as AIG, HSBC unnerve investors

NEW YORK, March 2 (Reuters) - Global stocks plumbed new multi-year lows on Monday after AIG's record $61.7 billion quarterly loss and an $18.1 billion capital request by HSBC slammed financial markets, sending the dollar to near three-year highs and government debt up as investors sought safe havens.
Oil prices plunged 10 percent as the deteriorating world economy threatened to cut further into fuel consumption.
Insurer American International Group's <AIG.N> quarterly loss, the largest in U.S. corporate history, heightened worries about the health of the global financial system and boosted the appeal of government debt and the dollar as low-risk havens. For details, see [
].The worldwide rout in equity markets pushed the Dow and S&P 500 stock indexes below key levels, while the FTSEurofirst 300 <
> index of leading European shares ended a whisker away from a lifetime low.The latest bailout of AIG, which lost a total of $99.29 billion last year, unnerved investors who have been seeking assurances that the credit crisis that began in mid-2007 is finally abating. The worsening global economy has only exacerbated sentiment.
"The weight of the evidence is that we're still in a very risky condition in the general economy, and so we're going to new lows," said Joseph Battipaglia, market strategist for Stifel Nicolaus in Yardley, Pennsylvania.
"You can conclude there is a deteriorating confidence in the government's ability to stem the financial crisis -- plain and simple."
The decision by HSBC, Europe's biggest bank, to raise funds via a rights issue to help it overcome big losses contributed to fears that the downward trend is picking up pace.
Stocks sold off worldwide. European shares closed down 5 percent and Asian stocks fell about 4 percent.
U.S. stocks fell 4 percent or more as the Dow closed under the 7,000 mark for the the first time since May 1997 and the S&P 500 slid below 700, before closing slightly higher. [
]Global stocks, as measured by MSCI's all-country world equity index <.MIWD00000PUS>, fell almost 5 percent to an almost six-year low.
All 30 components of the Dow closed in the red, and only seven stocks in the S&P 500 rose. Declining shares outnumbered advancing shares by more than 15 to 1 among the 3,168 issues that traded on the New York Stock Exchange, and more than one out of every five of those issues fell to 52-week lows.
Analysts said the news reaffirmed suspicion that more turmoil lies ahead, spurring investors to sell stocks for safer, dollar-denominated alternatives such as Treasuries.
"This is just creating an overall environment where if things get worse at AIG, we could see further write-downs and more problems in the financial sector," said Mark Frey, head of FX trading at global payments dealer Custom House in Victoria, British Columbia.
