* Brent premium to U.S. crude contracts * U.S. crude stocks seen lower last week - poll * Coming up: API oil data 4:30 p.m. EDT, Tuesday NEW YORK, Sept 13 (Reuters) - U.S. crude futures rose Tuesday as the dollar index slipped and investors anticipated weekly reports would show that crude stocks fell again last week in the United States. U.S. crude stockpiles were expected to have fallen 3 million barrels last week, a preliminary Reuters survey of analysts showed on Monday. Gasoline stocks were expected to have slipped 400,000 barrels, with distillates seen up 800,000 barrels. The dollar slipped back from Monday's 7-month high versus a currency basket of 77.784 . The U.S. currency fell against the traditional safe-haven Japanese yen, edging closer to its record low and raising expectations that the Bank of Japan could soon intervene to cap the rise. Front-month October Brent crude, approaching expiration on Thursday, slipped in choppy trading as its premium to U.S. crude continued to narrow. It was below $23 a barrel after surging to a record above $27 a barrel last week. The possible return of Libyan oil to the market and lowered demand forecasts from the International Energy Agency helped pressure Brent. The International Energy Agency in its monthly report on Tuesday cut its estimate of global oil demand growth this year by 160,000 barrels per day (bpd) to 1.04 million bpd and trimmed its 2012 demand growth estimate by 190,000 bpd to 1.42 million bpd. While Brent has been in backwardation, a condition where the front-month price is higher than months further out, U.S. crude has been in contango, with higher prices going forward. But the spread between front-month U.S. crude and the next month narrowed to less than 10 cents intraday on Tuesday.
