* Iran says IAEA access to nuclear site images has ended
* Market widely expects eventual re-entry of Iranian oil
* Brent prices to reach $80/bbl in Q4 2021 - Goldman Sachs (New throughout, updates prices, market activity, comments; new byline, changes dateline, previous LONDON)
NEW YORK, May 24 (Reuters) - Oil prices rose on Monday as a demand bump fueled by COVID-19 vaccination drives gave traders optimism that the market can absorb any Iranian oil that would come on the market if Western talks with Tehran lead to the lifting of sanctions.
Prices also got a boost on expectations that a new deal is les likely than it was last week, said Bob Yawger, director of Energy Futures at Mizuho in New York.
“The Iranians and western powers cannot get the details worked out that will get this deal signed and delivered,” Yawger said.
Brent crude oil futures for July were up $1.72, or 2.6%, at $68.17 a barrel by 11:39 ET (1539 GMT), while July U.S. West Texas Intermediate was at $65.43 a barrel, up $1.85, or 2.9%.
Goldman Sachs said the case for higher prices remained intact even with a potential increase in Iranian exports. Its new base case for an October restart still supports an $80 per barrel forecast for this summer, it added.
“Even aggressively assuming a restart in July, we estimate that Brent prices would still reach $80 per barrel in fourth quarter 2021,” the bank said in a note.
Iran and the U.N. nuclear watchdog are extending a recently expired monitoring agreement by a month, both sides said on Monday, avoiding a collapse that could have pitched wider talks on reviving the 2015 Iran nuclear deal into crisis.
Former President Donald Trump withdrew the United States from the deal in 2018 and re-imposed sanctions.
Even if large volumes of Iranian crude return to the market, it is unlikely to stall the drawdown in global oil stocks,” said Stephen Brennock of oil broker PVM.
“Additional supply from Tehran is poised to be absorbed by the market as a result of a vaccine-spurred surge in demand over the coming months,” he added. (Additional reporting by Noah Browning and Jessica Jaganathan; Editing by Kirsten Donovan and David Gregorio)
