Oil prices inched lower on Wednesday, extending the previous session's declines as investors assessed the US-Iran peace deal, though uncertainty over the full resumption of shipping through the Strait of Hormuz limited further falls.
Brent crude futures dipped 16 cents, or 0.2%, to $78.80 a barrel by 0340 GMT, while US West Texas Intermediate fell 25 cents, or 0.3%, to $75.80 a barrel.
Both benchmarks fell about 5% for a second straight session on Tuesday to stand at three-month lows, on hopes that a US-Iran deal would allow oil flows through the Strait.
"Markets are broadly stripping out the embedded geopolitical risk premium in oil prices," said Priyanka Sachdeva, senior market analyst at Phillip Nova.
"That said, the path toward normalization remains far from straightforward. While political agreements may be progressing, physical tanker traffic through the Strait has yet to fully recover."
The deal would provide for the United States to lift its blockade of Iran's ports, while Tehran would allow oil tanker traffic through the Strait, effectively blocked since US and Israel strikes on February 28.
"Oil markets retreated on expectations the Strait of Hormuz would reopen following the peace agreement, but traders held off further selling pending details," said Hiroyuki Kikukawa, chief strategist of Nissan Securities Investment.
WTI is likely to stay volatile in a range of $10 above or below $80 a barrel, he added.
Before the closure, about a fifth of global crude oil and liquefied natural gas supplies flowed through the Strait.
Details of the interim peace deal began to emerge on Tuesday, with President Donald Trump saying it would rule out a nuclear weapon for Tehran and a US official saying it would allow Iran to sell oil upon signing.
The memorandum of understanding, not yet public, extends by another 60 days a tenuous ceasefire agreed in April, so as to allow room for talks toward a permanent truce.
Still, industry officials say a full return to pre-war production and refining levels is likely to take weeks, months or even years.
Israel has distanced itself from both the April ceasefire and the latest US-Iran pact, fueling uncertainty about whether it will hold.
Israeli drone strikes targeted three vehicles in southern Lebanon on Tuesday, killing at least four and wounding others, Lebanon's National News Agency said, prompting a rare public rebuke from Trump.
China's crude oil throughput fell 9.1% in May on the year to its lowest in almost four years, data showed, also signaling that refiners were starting to draw on stockpiles amid the Iran war.
The American Petroleum Institute report showed US crude stocks fell 8.3 million barrels in the week ended June 12, the sources said.
It exceeded expectations for a draw of 4.6 million barrels, with official numbers due from the Energy Information Administration at 10:30 a.m. ET (1430 GMT) on Wednesday.
