NEW YORK, March 7 (Reuters) - Brent oil prices hit a high for the year above $40 a barrel on Monday after data showed a smaller-than-expected build in U.S. crude stockpiles, helping U.S. stocks extend recent gains.
Brent LCOc1 was last up $1.87 at $40.59, while U.S. crude CLc1 rose $1.58 to $37.50. lifted shares of energy stocks, which led gains in the S&P 500. The energy index .SPNY climbed 1.5 percent. Biotechs also rallied, helping to support the broader market.
The Dow Jones industrial average .DJI was up 65.23 points, or 0.38 percent, to 17,072, the S&P 500 .SPX had gained 3.86 points, or 0.19 percent, to 2,003.85 and the Nasdaq Composite .IXIC had added 9.78 points, or 0.21 percent, to 4,726.80.

The euro tumbled against the dollar before Thursday's ECB meeting at which policymakers are expected to cut interest rates further into negative territory.

In the U.S. bond market, U.S. Treasury yields rose in volatile trading as traders increased bets the Federal Reserve will raise interest rates this year in the wake of a strong February jobs report and ahead of a ECB meeting. payrolls data showed 242,000 jobs were created last month and assuaged fears the U.S. economy could be headed into recession. It also revived prospects of further Federal Reserve interest rate hikes this year, something markets had priced out.
