Oil prices jump ahead of US Fed rate decision

Oil prices climbed around 1% on Tuesday on bargain hunting, recovering some ground from the previous day's plunge, but gains were limited as investors remained cautious ahead of key policy decisions by the US Federal Reserve and other central banks.

Brent crude futures climbed 77 cents, or 1.1%, to $72.61 a barrel by 0640 GMT. US West Texas Intermediate (WTI) crude was at $67.68 a barrel, up 56 cents, or 0.8%.

Both benchmarks fell around $3 a barrel on Monday after analysts highlighted rising global supplies and concerns about demand growth just ahead of key inflation data and a two-day Fed monetary policy meeting concluding on Wednesday.

"Some investors looked for bargains after the previous day's heavy selling while others held back their positions with speculation that Saudi Arabia may cut production additionally," said Tatsufumi Okoshi, a senior economist at Nomura Securities.

Oil prices could fall further because of China's faltering economic recovery, he added, predicting WTI would trade in the range of $62.50 to $75 a barrel during the summer, but mainly below $70 a barrel.

Most market participants expect the US central bank to leave interest rates unchanged at its policy meeting. The Fed's rate hikes have strengthened the greenback, making dollar-denominated commodities more expensive for holders of other currencies and weighing on prices.

The European Central Bank (ECB) is expected to hike interest rates by another quarter percentage point on Thursday to tame stubborn inflation. But the Bank of Japan, which will announce its plan on Friday, is expected to maintain its ultra-loose policy.

In China, disappointing economic data last week raised concerns about demand growth in the world's largest crude importer, offsetting a boost in prices from Saudi Arabia's pledge to cut more production in July.

The market is also waiting for demand outlooks from Organization of Petroleum Exporting Countries (OPEC) and the International Energy Agency (IEA), due later on Tuesday, Nomura's Okoshi said.

"In our view, the latest fall in oil prices increases the probability Saudi Arabia will at least extend supply cuts currently in place for July," said National Australia Bank analysts in a note.

"On this basis, market speculation on the potential for further supply cuts at the next OPEC meeting is likely to drive oil price volatility."

Saudi Arabia last week said it would cut its July output by 1 million bpd to 9 million bpd, its biggest reduction in years, in a move to boost prices.
