Oil prices eased today in volatile trade as investors braced for the possible return of sanctioned Iranian oil exports to the market and on worries that rising U.S. interest rates would weaken fuel demand.
The prospect that the OPEC+ producer group could curb oil supplies limited the decline in oil prices.
Brent crude fell 4 cents to $101.18 a barrel by 1541 GMT, while US West Texas Intermediate crude fell 33 cents, or 0.4%, to $94.56 a barrel.
Talks between the European Union, the United States and Iran to revive the 2015 nuclear deal are continuing, with Iran saying it had received a response from the United States to the EU's "final" text to resurrect the agreement.
Investors also were waiting for scheduled remarks on Friday by US Federal Reserve Chair Jerome Powell, who is expected to Kansas City Fed's Economic Policy Symposium in Jackson Hole, Wyoming.
"The (market) is a little bit concerned about what Jerome Powell is going to say tomorrow about rising interest rates," said Phil Flynn, an analyst at Price Futures group in Chicago.
Powell is expected to summarize where the Fed stands in its fight to control inflation, including information about its rate-path hike in the long and short-term.
Limiting the downside for oil prices were comments on Monday by Saudi Energy Minister Prince Abdulaziz bin Salman that helped push prices to three-week highs, when he flagged the possibility that OPEC+ could cut production.
"It may (make) the chance of a move back below $90 in the near-term hard to come by unless a nuclear deal is agreed upon and OPEC+'s appetite for cuts put to the test," Oanda analyst Craig Erlam said.
Falling US crude and product stockpiles also helped support prices. Oil inventories fell by 3.3 million barrels in the week to August 19 to 421.7 million barrels, steeper than analysts' expectations in a Reuters poll for a 933,000-barrel drop.
The bullish impact was countered by a drawdown in gasoline inventories that was less than expected, reflecting weak demand.
US gasoline stocks fell by 27,000 barrels in the week to 215.6 million barrels. Analysts had forecast a 1.5 million-barrel drop.
