NEW DELHI/TOKYO, Oct 1 (Reuters) – Oil prices fell 1% on Thursday as recovering crude exports from the Gulf and a surprise rise in US inventories eased supply ​concerns, while investors weighed renewed US-Iran diplomatic efforts to end their ‌conflict in the Middle East.

Brent crude futures fell 1.1% to $96.92 a barrel by 0420 GMT, and US West Texas Intermediate crude dropped 1.4% to $89.18 a barrel.

Both benchmarks rose about $1 a barrel on Wednesday. Brent recorded a monthly gain of around 14% in September, its ‌biggest ​since July, while WTI increased by about 5% ⁠on the month.

“Oil’s near-term bias ⁠remains negative as recovering shipments from the Gulf region, resumed Saudi exports through Yanbu and a buildup in US inventories ease supply concerns,” said Sugandha Sachdeva, founder of SS WealthStreet, a New Delhi-based research firm.

Saudi Arabia ​resumed oil tanker loadings from Yanbu, Reuters reported on Tuesday, after earlier restarting operations on its East-West Pipeline.

Meanwhile, US crude inventories rose by 922,000 ⁠barrels to 427.3 million barrels in the ⁠week ended September 25, the Energy Information Administration said, compared ​with expectations in a Reuters poll for a 264,000-barrel draw. [EIA/S]

“Renewed US-Iran diplomatic engagement ​could further reduce the geopolitical risk premium, although a breakthrough remains ‌uncertain,” Sachdeva said.

Iran said on Wednesday it had received a US response to its latest proposal to resurrect the collapsed ceasefire in the Gulf.

US President Donald Trump denied reports by Axios and CNN, however, that cited US officials ⁠as saying he was willing to give Iran sanctions relief and release frozen Iranian funds in return for “concrete” steps by Tehran on its nuclear programme.

Goldman Sachs estimates ⁠Gulf oil exports, including “dark ‌exports” involving ships operating with their location transponders turned ⁠off, have recovered to 23.3 million barrels per day ​over the ‌last week, in line with their 2025 average, as ​exports doubled ⁠in September, it said in a note on Tuesday.

Also, OPEC+ oil-producing countries are likely to keep their oil production targets steady for November when they meet on Sunday, two people with knowledge of the matter told Reuters.
