Fear that Europe’s debt crisis is infecting Germany, the strongest economy in the region, sent stocks reeling Wednesday.
The Dow Jones industrial average dropped 236 points, leaving it down 4.6 percent over the past three days. The Standard & Poor’s 500 index fell for the sixth day in a row, its worst losing streak since August.
Traders were spooked by the poor results at an auction of German debt, which drew too few bids to sell all of the 10-year notes being offered. Germany has Europe’s strongest economy, and traders have bought its debt as a safe place to store value during turbulent times.
The weak buying suggests that Europe’s crisis might be infecting strong nations that are crucial to keeping the euro currency afloat. Germany bears much of the burden of bailing out weaker neighbors such as Greece and Portugal.
Borrowing costs for Italy and Spain rose from levels that already were considered dangerously high. Europe lacks the resources to bail out those countries, which have its third- and fourth-biggest economies.
The Dow fell 236.17 points, or 2.1 percent, to close at 11,257.55. It has slumped this week as Congress neared a deadlock on cutting the budget deficit and as Europe’s debt woes appeared to worsen. The Dow has now given back more than half of its big October rally. It jumped 9.5 percent last month, the biggest gain since 2002.
The Standard & Poor’s 500 index fell 26.25, or 2.2 percent, to 1,161.79. All 10 industry groups fell sharply, led by energy companies, materials makers and banks. The index is headed for its sixth straight decline, the longest losing streak since August.
The Nasdaq fell 61.20, or 2.4 percent, to 2,460.08.
The dollar rose sharply against the euro as investors moved money into assets considered relatively safe.
Fears about Europe also dragged U.S. bank stocks lower. Investors were unnerved by the Federal Reserve’s announcement late Tuesday of a fresh round of stress tests of the biggest banks, said Peter Tchir, who runs the hedge fund TF Market Advisors.
The Fed said 31 banks will be tested to see how they would withstand a recession that would push unemployment above 13 percent by early 2013. The jobless rate now stands at about 9 percent.
The announcement undermined weeks of market-boosting talk by Fed officials, Tchir said. The stress tests, apparently related to fears about European exposure, exposed a darker view of the market held by some central bank officials, he said.
“They went ahead and put weakness into the market for the first time” in months, Tchir said. “No one was that afraid, and now all of a sudden, they’re saying ‘Our own Fed is worried.’ That really spooked people.”
Trading was light ahead of the Thanksgiving holiday. U.S. markets will be closed today and will have shortened hours on Friday. Volume on the New York Stock Exchange was 3.8 billion shares, below the average of 4.7 billion over the past 100 days.
