Oil prices were near 2019 highs on Tuesday after Washington announced all Iran sanction waivers would end by May, pressuring importers to stop buying from Tehran.
Brent crude futures were at $74.29 per barrel at 04:42 GMT, up 0.3 percent from their last close and not far off a 2019 peak of $74.52 reached on Monday.
U.S. West Texas Intermediate (WTI) crude futures hit their highest level since October 2018 at $65.95 per barrel before edging back to $65.86 by 02:39 GMT, which was still up 0.5 percent from their last settlement.
The United States on Monday demanded that buyers of Iranian oil stop purchases by May 1 or face sanctions, ending six months of waivers which allowed Iran's eight biggest buyers, most of them in Asia, to continue importing limited volumes.
