Oil prices rise on softer dollar, OPEC cut expectations

By Dmitry Zhdannikov, Keith Wallis and David Gaffen LONDON/NEW YORK (Reuters) - Oil prices rose in quiet trading on Thursday, supported by strong U.S. economic data, a pause in the U.S. dollar rally and optimism that crude producers would abide by an agreement to limit output. The dollar index , which tracks the greenback against a basket of six currencies, slipped by 0.3 percent as investors took profits after its rise to a 14-year peak earlier this week.
