Brent crude futures for November settlement rose three cents to $92.03 a barrel by 0449 GMT.
US West Texas Intermediate crude for October delivery was at $85.76 a barrel, up three cents. The October contract will expire on Tuesday and the more active November contract was at $85.29, down seven cents, or 0.1 per cent.
The dollar remained firm below a two-decade high versus major peers on Tuesday, ahead of a slew of central bank meetings around the world this week led by the US Federal Reserve, which is likely to raise interest rates by another 75 basis points to rein in inflation.
The stronger greenback makes dollar-denominated oil more expensive for buyers using other currencies and the expected rate increases have increased concerns that the tightening could trigger a global recession.
“Oil prices have been sliding in a downtrend since mid-June, and recession fears and a slowdown growth in China are still the major bearish factors in general,” said Tina Teng, an analyst at CMC Markets.
While other major economies are tightening, China, the world’s second-largest oil user on Tuesday left its benchmark lending rates unchanged as it tries to balance supporting its sluggish economic growth against the weakening yuan.
Fears of aggressive central bank tightening are still driving concerns for a “quickly weakening global economy” and pressuring crude prices, said Edward Moya, a senior market analyst at Oanda, in a note.
US crude oil stocks are estimated to have risen last week by around two million barrels in the week to Sept 16, a preliminary Reuters poll showed on Monday.
The US Energy Department will sell up to 10mn barrels of oil from the Strategic Petroleum Reserve for delivery in November, extending the timing of a plan to sell 180m barrels from the stockpile to tame fuel prices.
Signs that major producers are unable to meet their output quotas did give prices some support.
An internal document from the Organisation of Petroleum Exporting Countries and allies led by Russia, known as Opec+, showed the group fell short of its oil production target by 3.583m barrels per day (bpd) in August. In July, the group missed its target by 2.892m bpd.
The impasse over a revival of the Iran nuclear deal is also continuing to keep that country’s exports from fully returning to the market.
Russia said on Monday that unresolved issues remained in the negotiations while France’s foreign minister said that it was up to Tehran to make a decision as the window to find a solution was closing.
However, they are signs that higher oil prices this year are curbing demand. US vehicle travel in July fell 3.3pc from a year earlier, dropping for a second month.
