Oil edged up on Wednesday, a day after prices fell through $100 a barrel for the first time since April, but gains were limited by caution ahead of U.S. inflation data that could weaken the market.
Brent crude futures were up 45 cents, or 0.5%, at $99.97 a barrel at 0630 GMT. Nymex gained 44 cents, or 0.5%, to $95.27.
Investors have sold oil positions on worries that aggressive interest rate hikes to stem inflation will sharply slow economic activity and hit oil demand. Prices fell by more than 7% on Tuesday in volatile trading.

Economists polled by Reuters expect the figures to show that U.S. inflation has accelerated, to 1.1% monthly and 8.8% annually.

US crude stocks rose by about 4.8 million barrels for the week ended 8 July. Gasoline inventories rose by 3 million barrels, while distillate stocks rose by about 3.3 million barrels, according to market sources citing American Petroleum Institute figures on Tuesday.
Meanwhile, the market also is closely watching U.S President Joe Biden's visit to the Middle East, where he is expected to ask Saudi Arabia and other Gulf producers to raise oil output to help stabilise prices.
In a monthly report issued on Tuesday, OPEC expected that global oil demand would rise in 2023 and that the market would remain tight. It estimated that an additional 900,000 bpd of oil would be needed from its members in 2023 to balance the market.
