NEW DELHI, May 2 (Reuters) - Oil prices rose on Thursday, rebounding from three days of losses, on expectations the lower levels may prompt the U.S., the world's biggest crude consumer, to start replenishing its strategic reserve, putting a floor under prices.
Still, prices fell more than 3% on Wednesday to a seven-week after the U.S. Federal Reserve kept interest rates steady, which may curtail economic growth this year and limit oil demand increases.
Crude was also pressured by an unexpected increase in U.S. crude inventories and signs of an impending Israel-Hamas ceasefire that would ease Middle East supply concerns.
Brent crude futures for July gained 58 cents, or 0.7%, to $84.02 a barrel by 0633 GMT on Thursday. U.S. West Texas Intermediate (WTI) crude for June climbed 53 cents, or 0.7%, to $79.53 a barrel.
"The oil market was supported by speculation that if WTI falls below $79, the U.S. will move to build up its strategic reserves," said Hiroyuki Kikukawa, president of NS Trading, a unit of Nissan Securities.
The U.S. has said it aims to replenish the Strategic Petroleum Reserve (SPR) after a historic sale from the emergency stockpile in 2022 and wants to buy back oil at $79 a barrel or less.
In the Middle East, expectations grew that a ceasefire agreement between Israel and Hamas could be in sight following a renewed push led by Egypt.
Still, Israeli Prime Minister Benjamin Netanyahu has vowed to go ahead with a long-promised assault on the southern Gaza city of Rafah despite the U.S. position and a U.N. warning that it would lead to "tragedy".
"As the impact of the U.S. crude stock-build and the Fed signalling higher-for-longer rates is close to being fully baked in, attention will turn towards the outcome of the Gaza talks," said Vandana Hari, founder of oil market analysis provider Vanda Insights.
"As long as the latest bout of optimism over a ceasefire sustains, I expect a continued downside bias in crude," Hari added.
The U.S. Energy Information Administration (EIA) said crude inventories rose by 7.3 million barrels to 460.9 million barrels in the week ended April 26, compared with analysts' expectations in a Reuters poll for a 1.1 million-barrel draw.
Crude stocks were at the highest point since June, the EIA said.
The U.S. Federal Reserve held interest rates steady on Wednesday and signalled it is still leaning towards eventual reductions in borrowing costs, but put a red flag on recent disappointing inflation readings.
Any delay in rate cuts could slow economic growth and dampen demand for oil.
Still, continuing supply reductions by the Organization of the Petroleum Exporting Countries (OPEC) and its allies, known as OPEC+, will support prices.
Analysts at Citi Research expects OPEC+ to hold output cuts through the second half of the year as it meets on June 1.
However, "if prices move to a bull case $90-100+ range, OPEC+ would likely ease cuts, providing a soft ceiling for oil," they said in a note.
