RoydadNaft –  Oil prices reached their highest level since late September on Wednesday after a major winter storm disrupted U.S. crude production, while a weaker U.S. dollar and ongoing disruptions in Kazakhstan provided further support.

According to Roydad Naft, at 10:17 GMT, Brent crude futures pulled back, falling 39 cents or 0.6% to $67.18 per barrel. U.S. WTI crude fell 22 cents or 0.4% to $62.17.

Both benchmarks had risen around 3% on Tuesday.

The U.S. dollar was hovering near its four-year low against a basket of other currencies (.DXY), signaling weakness that makes dollar-denominated commodities like oil cheaper for holders of other currencies.

On the supply side, crude exports from U.S. Gulf Coast ports dropped to zero on Sunday before recovering on Monday, after a massive winter storm swept across the country, according to ship-tracking service Vortexa.

Kazakhstan production gradually resuming

Lost production in Kazakhstan also supported higher prices, although the OPEC+ member hopes to gradually resume output at the Tengiz field within a week. However, sources say it could take longer.

Meanwhile, the operator of the CPC pipeline, which handles about 80% of Kazakhstan’s oil exports, has restored full loading capacity at its Black Sea terminal after repairs to a mooring point damaged by drones.

On the supply front, the OPEC+ group—including OPEC, Russia, and other allies—is expected to maintain the pause on production increases for March at its February 1 meeting, according to OPEC+ delegates.

Elsewhere, U.S. officials are working on a general license that would lift some sanctions on Venezuela’s energy sector, which could put downward pressure on prices.

A U.S. aircraft carrier and support ships have arrived in the Middle East, U.S. officials told Reuters, increasing President Donald Trump’s options for defending U.S. forces or taking potential military action against Iran. This has heightened concerns over supply disruptions from OPEC’s fourth-largest oil producer.

On the demand side, U.S. crude and gasoline inventories were expected to rise in the week ending January 23, while distillate stocks were likely to fall, according to a Reuters survey.

Official government data will be released at 15:30 GMT.
