The Federal Reserve could later on Tuesday reinforce a view prompted by recent data that the US economy is recovering, buoying the demand outlook for the world’s largest oil consumer, but it is unlikely to kick off further quantitative easing.
Brent crude rebounded 66 cents to $126 early on Tuesday, after settling down on Monday for the first time in four sessions. The April Brent contract expires on Thursday. US April crude was up 63 cents at $106.97.
