* Prices fall as stocks jump on stronger economic data * Volumes seen dropping as U.S. East Coast prepares for snowstorm * Treasury to sell $72 bln in new 3, 10 and 30-year bonds By Karen Brettell NEW YORK, Feb 8 U.S. Treasuries fell on Friday, erasing some of Thursday's gains, after stocks jumped and as investors prepared for $72 billion in new supply next week. The Treasury will sell $32 billion in three-year notes on Tuesday, $24 billion in 10-year notes on Wednesday and $16 billion in 30-year bonds on Thursday. A stronger-than-expected reduction in the trade deficit on Friday was also seen helping riskier stocks gain, reducing demand for safe haven bonds. "We're just following stocks at this point," said Rick Klingman, a Treasuries trader at BNP Paribas in New York. "The trade deficit number implies that there is going to be a decent upward revision in GDP, so I think that helps with the stocks." A rise in exports and lower imports of oil helped push the U.S. trade deficit to its narrowest point in nearly three years in December, data showed on Friday. Benchmark 10-year Treasuries yields fell 6/32 in price to yield 1.99 percent, up from 1.96 percent late on Thursday. The note's yields fell as low as 1.93 percent on Thursday after comments from European Central Bank President Mario Draghi raised speculation that the bank would cut interest rates to stem the region's strengthening currency. Ten-year Treasuries are now trading in the middle of what traders see as a range between around 1.90 percent and 2.03 percent. A dramatic selloff in late January and early February pushed the 10-year notes to more than eight month highs of 2.06 percent on February 4. Trading volumes are expected to taper off on Friday as residents on the U.S. East Coast prepared for a large snowstorm in the region. The Federal Reserve will buy between $1 billion and $1.5 billion in Treasury Inflation-Protected Securities (TIPS) due between 2020 and 2042 on Friday as part of its ongoing bond purchase program.
