NEW YORK, May 28 (Reuters) - U.S. stocks rose as oil prices surged over $65 a barrel on Thursday on a drawdown in inventories, while U.S. Treasury debt recovered some ground a day after worries about a record $1.75 trillion budget deficit sparked a sharp sell-off.
The Japanese yen fell broadly after the spike in U.S. bond yields and surprisingly strong U.S. durable goods orders data suggested the recession may be easing, attracting investors in the safe-haven Japanese currency back into riskier assets.
The U.S. dollar also remained under pressure against the euro as the economic data reduced the need to hold it as a safe haven also, and as worries about a soaring U.S. fiscal deficit bolstered hopes that the Federal Reserve would step up debt purchases.
U.S. government debt prices jumped in a volatile session, with 30-year long bonds rising more than two full points as traders welcomed the end of $101 billion in new issuance auctions that had reinforced worries about the growing U.S. debt burden.
Crude oil prices jumped to a fresh six-month high after the Organization of Petroleum Exporting Countries (OPEC) decided to keep output unchanged. U.S. government data also showed a steep drop in U.S. crude inventories, suggesting demand may be rising again as the summer driving season begins..
"Gasoline demand over the Memorial Day weekend is a critical point in judging the health of the U.S. economy," said analyst Phil Flynn at Alaron Trading in Chicago. "I don't think the increased demand over the holiday was a fluke."
U.S. crude oil for July delivery <CLc1> settled up $1.63 to $65.08 a barrel after hitting an intraday high of $65.44. It was the highest settlement since Nov. 5.
London Brent crude <LCOc1> rose $1.89 to settle at $64.39.
OPEC Secretary-General Abudullah al-Badri told Reuters Financial Television that U.S. demand was showing signs of recovering after the financial crisis battered global consumption and sent oil prices tumbling from near the record of $150 of last July.[
]OPEC ministers meeting in Vienna opted to leave target output levels unchanged as they bet a strengthening economy and signs of rising demand would support prices. [
]U.S. stocks climbed as the jump in crude oil prices drove up energy sector shares and as data on U.S. durable goods orders signaled the economy was stabilizing.
Chevron Corp <CVX.N> and Exxon Mobil Corp <XOM.N> were top gainers on the blue-chip Dow.
"We had the OPEC meeting today plus we had inventory numbers and both were favorable for oil, and that's helping that whole sector," said Owen Fitzpatrick, head of U.S. Equity Group at Deutsche Bank Private Wealth Management in New York.

"Yesterday had the smell of an overshoot," said Alan Ruskin, chief market strategist at RBS Greenwich.
Ruskin and others cited speculation that the recent pullback in Treasury yields to six-month highs might soon push the Federal Reserve to step up its purchases of government, agency and mortgage bonds.
