Oil prices rose on Wednesday as doubts about ?a US-Iran peace deal and attacks on two ships fuelled concerns about disruptions to Middle East supplies, although ?industry data showed swelling inventories of US crude.
Brent futures were up 75 cents, or 0.84 percent, to $89.66 a barrel by 08:53 a.m. Saudi time, while US West Texas Intermediate crude climbed 72 cents, or 0.87 percent, to $83.92. Both contracts had risen more than $1 earlier in the session.
That followed Tuesday's rises of more than $1 ?for the highest closes of both contracts since July 31.
Prices had jumped about 5 percent on Monday as hopes ?began to fade for a peace deal between the US and Iran, after President Trump issued a ?new demand that Iran offer compensation for those killed in wars, attacks and protests.
"The Middle East is increasingly becoming a seesaw ?between 'deal' and 'war', keeping oil prices swinging like a pendulum between $70 and $90 a barrel," said Priyanka Sachdeva, head of market insights for ?Phillip Nova in Singapore.
The US and Yemen's Iran-aligned Houthis reported separate attacks on shipping in the Strait of Hormuz and the Bab el-Mandeb Strait on Tuesday.
Iran's top security official, Mohsen Rezaei, said the vital Strait of Hormuz would stay closed unless the US accepted Iran's conditions to end the ?war, including release of its frozen assets and an end to other regional conflicts.
The US may let Iran "bop along" or "hit ?them really, really hard," Trump said in a Tuesday interview.
Throughout the conflict he has alternated between threats of escalation and claims that a peace ?deal is ?imminent.
But the uncertainty could be profitable for some, Sachdeva added.
"We may be entering an environment where markets simply adapt to this weekly flip in narrative," she said. "That creates a highly volatile but opportunity-rich landscape for intraday traders, scalpers and short-term speculators."
Shipping data showed that vessels transiting the Strait of Hormuz fell to a one-week low of eight on Tuesday.
Before the war, 125 to 140 ?vessels passed through the crucial ?waterway each day.
On the supply ?front, a Reuters poll showed on Tuesday that US crude oil and fuel inventories were expected to have fallen last week.
However, market sources citing American Petroleum Institute data said US crude inventories rose sharply ?in the week ended Aug. 7, while gasoline and distillate stocks fell.
Crude stocks rose by ?about 9.1 million ?barrels, while gasoline and distillate inventories fell by 1.5 million barrels and 596,000 barrels, respectively, from the previous week, the sources said.
The crude build far exceeded expectations and, if confirmed by the EIA report later on Wednesday, could ease market concerns about supply tightness, Haitong ?Futures said ?in a note.
Official numbers from the EIA, the statistical arm of the ?US Department of Energy, are due at 17:30 Saudi time.
For longer-term supply, the EIA expected disruptions of about 600,000 barrels per day to Middle East crude ?oil supplies to persist through the end of 2027.
