Oil rose on Wednesday, firming its ground near a 10-month peak reached during trading a day earlier, as the market balanced supply concerns over Libya output and OPEC+ cuts with global macroeconomic headwinds.

Benchmark Brent futures edged higher by 8 cents, or 0.1%, to $92.14 a barrel by 0630 GMT, while U.S. West Texas Intermediate (WTI) crude climbed 13 cents, or 0.2%, to $88.97 a barrel.

Both benchmarks surged nearly 2% on Tuesday to close at their highest levels since November 2022.

"Bullish demand outlook by the OPEC and the U.S. Energy Information Administration's (EIA) prediction of a decline in global oil inventories reinforced market views of tightening supply going forward," said Satoru Yoshida, a commodity analyst with Rakuten Securities.

The news of OPEC member Libya shutting four of its eastern oil export terminals due to a deadly storm also lent support to oil prices, he added.

"But further gains may be limited as there is also downside pressure from lingering worries over weaker demand in China," Yoshida said.

The Organization of the Petroleum Exporting Countries (OPEC) stuck to its forecasts for robust growth in global oil demand in 2023 and 2024, citing signs that major economies are faring better than expected despite headwinds such as high interest rates and elevated inflation.

Keeping supplies tight, Saudi Arabia and Russia last week extended voluntary supply cuts of a combined 1.3 million bpd to year end. OPEC, Russia and allied producers are known as OPEC+.

Russian oil production is seen declining by 1.5% to 527 million metric tons (10.54 million barrels per day) this year, newspaper Izvestia reported on Wednesday, citing an interview with Energy Minister Nikolai Shulginov.

The EIA, meanwhile, said global oil inventories were expected to fall by almost a half million bpd in the second half of 2023, causing oil prices to rise with Brent averaging $93 per barrel in the fourth quarter.

Front-month Brent futures contracts traded as high as $4.68 a barrel above those for delivery six months further out on Tuesday, a spread last seen in November last year, indicating tighter market supply in the near-term.

But U.S. crude oil, distillate and gasoline stockpiles rose last week, according to market sources citing American Petroleum Institute (API) figures on Wednesday.

Crude stocks rose by about 1.2 million barrels in the week ended Sept. 8, against analysts estimate of a draw of about 1.9 million barrels. Gasoline inventories rose by about 4.2 million barrels, while distillate inventories rose by about 2.6 million barrels.

The market also awaited U.S. inflation data due on Wednesday, with the year-on-year core consumer price index increase expected to moderate to 4.3% in August from a 4.7% gain in July. Investors will focus on whether a softer core inflation reading will be sufficient for the Federal Reserves to keep rates on hold into next year.
