Oil higher as OPEC delivers on output cuts, dollar dives

By Devika Krishna Kumar NEW YORK (Reuters) - Oil prices rose on Tuesday on a weak U.S. dollar and news that the world's top producers cut production this month more than forecasters had expected. "This is very high, a good number," an OPEC source said of the January compliance estimate. The currency tumbled against rivals on Tuesday and was on course for its worst January in three decades after comments from U.S. President Donald Trump and his trade adviser.
