Aug 6 (Reuters) - Oil prices held steady on Thursday amid market caution over whether talks between Iran and Oman will restore flows through the Strait of Hormuz, while reports of attacks on Saudi tankers in the Red Sea and Gulf of Aden renewed supply tensions.
Brent crude futures gained 9 cents, or 0.11%, to $79.54 a barrel by 0928 GMT. U.S. West Texas Intermediate futures added 5 cents, or 0.07%, to $75.27 a barrel.
"Traders still remember the short-lived Memorandum of Understanding
signed in June, so there is understandable anxiety that any new deal could prove equally fragile," said Tim Waterer, chief market analyst at KCM Trade.
Iran and Oman have reached an understanding on the geographic coordinates for a shipping route through the Strait of Hormuz, and a joint announcement is being finalised, provided certain third parties do not interfere, Iran's Foreign Ministry spokesperson Esmaeil Baghaei said on Wednesday.
A proposed deal between Iran and Oman to help end the U.S.-Iran conflict would give Tehran control over ships entering the Gulf through the Strait of Hormuz, a senior Iranian source and two regional officials told Reuters on Wednesday, one of the biggest concessions yet to Iran.
Before the conflict began in late February, the Strait of Hormuz handled about one-fifth of global daily oil and liquefied natural gas supplies.
GEOPOLITICAL RISKS PERSIST
"Until we see sustained, verifiable increases in volumes, the market will continue to price in a degree of supply risk," Waterer added.
Gulf countries' crude oil and condensate exports were largely steady in July and remained about 40% below pre-war levels, shipping data showed.
Iran has warned Gulf states that any new U.S. attack on its territory would trigger retaliation against critical energy infrastructure across the region, according to five sources, as Tehran seeks to raise the cost of military action by threatening Washington's closest regional allies.
Yemen's Iran-aligned Houthis said on Wednesday they had launched a missile attack on a Saudi oil tanker off the coast of the kingdom's Red Sea port city of Yanbu and another missile attack on a Saudi oil tanker in the nearby Gulf of Aden. There was no confirmation from Saudi Arabia on either incident.
"Houthi attacks so far have not significantly disrupted oil and gas supply but this might change if attacks escalate further," said Roberto Cominotto, equity research analyst at Julius Baer.
Meanwhile, Saudi Arabia has slightly lowered the official selling price for its flagship Arab Light crude oil to Asia in September, a pricing document reviewed by Reuters showed.
And elsewhere, a major oil refinery in Russia's Yaroslavl region is on fire after a big Ukrainian drone attack and emergency services are working to put out the blaze, Mikhail Evrayev, the regional governor, said on Thursday.
