The Brent crude price began trading today 5 percent up, over 88 dollars a barrel, as markets have not ruled out stricter US sanctions by the US against Iran, which supports Hamas, responsible for the weekend’s shock attack on Israel.

European and US markets are also expected to rise today, reflecting anxiety over an escalated conflict that would be brought about by an Israeli ground military operation in Gaza and the involvement of the powerful Hezbollah from the Israel’s north, with the support of Iran and Syria.

Should the US impose stricter sanctions on Iran, global oil supply would be reduced, creating an opportunity for Russia to increase its share, analysts have noted.

Washington, since late 2022, has turned a blind eye to an increase in Iranian exports circumventing US sanctions, on the basis of an informal détente with Tehran, analysts have reminded. The US has pursued such a course knowing it would hurt Russia.

Israel’s energy-related interests in the eastern Mediterranean, including talks with Cyprus and other regional players for gas exports to Europe, will now be put on hold following the Hamas attack on Israel.

Earlier today, Israel’s energy ministry ordered US oil giant Chevron to halt operations at the Tamar gas field, off the coast of Israel. The company stated it is complying with the ministry’s request.

The development of a Cypriot LNG terminal, planned to receive Israeli pipeline gas, and, even more crucially, a recent push by Israeli Prime Minister Benjamin Netanyahu for decisions promoting exports from east Mediterranean fields within the next three to six months, are now being brought to a standstill.

As for the role of Turkey, statements made yesterday by President Recep Tayyip Erdogan, who called for restraint from both sides without condemning the Hamas attack on Israel and spoke again of a Palestinian state with Jerusalem as its capital, probably reinforce Israel’s reservations against Turkey.

At a recent meeting in New York, Netanyahu and Erdogan agreed to schedule an exchange of visits aimed at restoring relations between the two countries. Erdogan, at that meeting, had proposed the transportation of Israeli gas to Europe via a subsea pipeline running alongside the Turkish coast.

Operations by Greece’s Energean Oil & Gas, listed on the London Stock Exchange, at licenses within the Israeli EEZ have not been disrupted by the conflict, company officials informed, noting the Energean Power FPSO and all other company facilities are not situated close to the battle zone.
