Oil prices were mixed on Friday following a potential renewal of supply risk, with Israel and Hezbollah trading accusations of ceasefire violations, and the postponement of an OPEC+ meeting having left investors waiting for a decision on OPEC's production policy.
Brent oil futures were down 7 cents, or 0.1 percent, at $73.21 a barrel by 0232 GMT. West Texas Intermediate crude oil futures were at $69.10, up 38 cents, or 0.55%, from Wednesday's closing price.
Trading remained limited due to the Thanksgiving holiday which closed US financial markets.
Israel and the Lebanese armed group Hezbollah exchanged accusations on Thursday over alleged violations of the ceasefire that came into force the day before. The deal initially appeared to ease the risk of supply disruption from a broader conflict that had led to a risk premium for oil.
Middle East oil supplies have been largely unaffected by Israel's parallel conflicts with Hezbollah in Lebanon and Hamas in Gaza.
Also on Thursday, Russia struck Ukrainian energy facilities for the second time this month. ANZ analysts said the attack risked retaliation that could affect Russia's oil supplies.
OPEC+, the Organization of the Petroleum Exporting Countries and its allies including Russia, postponed its next policy meeting from Dec. 1-5 to avoid conflict with another event. This meeting should make it possible to extend OPEC+ production cuts.
Iran has told the UN nuclear watchdog it will install more than 6,000 additional centrifuges at its enrichment plants, according to a confidential report by the watchdog released Thursday.
Analysts at Goldman Sachs said Iran's supply could fall by 1 million barrels a day in the first half of next year if Western powers tighten sanctions on its crude production.
