(Adds U.S. market close)
By Herbert Lash
NEW YORK, Feb 28 (Reuters) - European equities and U.S. equities declined and treasuries prices climbed as the dollar dropped to a new low against the euro on Thursday amid fresh signs of a possible U.S. recession.
Oil, which benefits from the weak dollar, jumped to another new high over $100, while gold continued its climb to record levels near $1,000 an ounce.
U.S. Treasury prices rose as investors scrambled for safety on fears that the worst has yet to arrive in the battered U.S. housing sector and on economic weakness that was highlighted in a fourth-quarter update on gross domestic product.
Investors were unnerved by reports that the U.S. economy barely expanded, with growth at just 0.6 percent, and that the number of workers filing claims for jobless aid jumped last week.
A second day of testimony by Federal Reserve Chairman Ben Bernanke in the Senate did little to help sentiment.
A safety-first focus set in early among investors after Freddie Mac, the second-largest U.S. provider of mortgages, posted a wider-than-expected quarterly loss of $2.5 billion before the bell trade opened on Wall Street.
Credit risk worries were fanned after Bernanke said that some small banks may go under as the housing slump takes its toll, although the U.S. banking system overall remained solid.
He added that the U.S. central bank is in a more difficult position now to respond to a slowing economy than it was during the last U.S. economic slowdown in 2001 following the bursting of the stock market bubble.
Bernanke's comments accelerated a fall in European and U.S. shares, with the major European stock indices closed down almost 2 percent and major U.S. indices were down more than 1 percent at midday. U.S. government debt surged.

"European equities are vulnerable to a slowdown in the (United) States spreading to Europe, exacerbated by the euro's strength, and on a currency-adjusted basis, they don't look massively attractive," said Andrew Bell, a strategist at Rensburg Sheppards Investment Management.
The FTSEurofirst 300 <

Bond prices jumped in the flight to safety and on the weak economic data. The benchmark 10-year U.S. Treasury note <US10YT=RR> was up 42/32, with the yield at 3.6868 percent.
"There's ongoing flight to safety in Treasuries because of credit risk. Equities look softer and we've got discouraging earnings reports from companies like Freddie Mac," said Kim Rupert, managing director of global fixed income analysis with Action Economics in San Francisco.
Cash moved into commodities again, as gold and oil set new records highs.
Investors have pumped cash into commodities in recent weeks, betting the Fed will keep cutting interest rates to prop up the flagging U.S. economy.
U.S. crude oil futures surged more than 3 percent to a record $102.70 and settled at $102.59, up $2.95 from the previous close.
Speculative buying on a weak dollar, ongoing supply concerns and a fire at a natural gas terminal in the United Kingdom pushed oil priced higher.
"Speculators own this market, and they are pushing it up as they see fit," said Stephen Schork, editor of the Schork Report.
The euro rose above $1.52 for the first time in its nine-year history as investors bet U.S. interest rates are set to fall further as Europe's benchmark rate stays unchanged.
The euro <EUR=> was up 0.61 percent at $1.5213 from a previous session close of $1.5121.
Gold raced to a historic high above $969 an ounce as the dollar's slump and strong oil prices boosted buying. Spot gold prices <XAU=> rose $11.10, or 1.16 percent, to $968.90. The Reuters/Jefferies CRB Index <.CRB> was up 8.16 points, or 2.01 percent, at 413.60.
"It's clearly the oil, clearly the weaker dollar, and people just want to have hard assets. I think people are very concerned. The economic news coming out of the United States is just bad," said Bruce Dunn, vice president of trading at Auramet Trading in Fort Lee, New Jersey.
