Oil prices suffered a last-minute turn lower on Thursday, giving up their highest levels in more than three years as reported comments from President Donald Trump fueled a rebound in the U.S. dollar. Prices were poised to mark another finish at a more than three-year high, buoyed by ongoing declines in U.S. crude inventories and a sharp decline in the greenback. But they turned lower in the minutes ahead of the futures settlement, just as CNBC reported that Trump said the U.S. dollar will strengthen over time and that he wants to see a strong dollar. The ICE Dollar Index hit three-year lows Wednesday after U.S. Treasury Secretary Steven Mnuchin said a weaker greenback was good for trade. The index continued to fall Thursday but when news of Trump’s comments broke, it moved higher. Commodities often trade inversely with the dollar as moves in the U.S. currency can alter their appeal to holders of other currencies.

Prices for natural gas, meanwhile, continued to retreat even as data showed U.S. supplies of the commodity fell more than expected last week. March West Texas Intermediate crude fell 10 cents, or nearly 0.2%, to settle at $66.51 a barrel on the New York Mercantile Exchange, after settling at a three-year high of $65.61 Wednesday. Brent for March fell 11 cents, or nearly 0.2%, to $70.42 a barrel on the ICE Futures Europe exchange, after a $71.28 high. The contract had finished Wednesday at $70.53 a barrel, also the highest since December 2014.

Continuing a string of declines, the EIA reported Wednesday that U.S. crude supplies fell 1.1 million barrels for the week ended Jan. 19. “On balance, U.S. oil stocks are down more than 47 [million barrels] over the last 10 weeks, which has been a supporting factor behind the recent price gains,” said analysts at the Sevens Report. However, the EIA data also showed total domestic crude production climbed by 128,000 barrels a day to 9.878 million barrels a day, which some analysts said could hamper crude’s march higher. “Total U.S. production is quickly approaching the milestone 10 [million barrel-per-day] mark, a level that is expected to cause some bearish angst among traders,” the Sevens Report analysts said.

Meanwhile, natural-gas futures finished lower, though briefly pared some of its earlier declines after the EIA reported Thursday that domestic supplies of natural gas fell by 288 billion cubic feet for the week ended Jan. 19. S&P Global Platts said that, according to its poll of analysts, the market expected a decline of 272 billion, and the latest weekly drop was much larger than the five-year average withdrawal of 164 billion. “The 288 bcf draw was solidly bigger than consensus and means we are in a new world for consumption volumes,” said Richard Hastings, macro strategist at Seaport Global Securities. But February natural gas fell 6.2 cents, or 1.8%, to $3.447 per million British thermal units, pulling back from gains that have seen the contract soar nearly 8% so far this week. It climbed nearly 2% Wednesday, when it logged its highest settlement since Dec. 30, 2016 as traders bet that frigid weather would drive hefty declines in supplies of the heating fuel. Some analysts said call for milder weather next week could keep those prices from climbing too high.
