Oil prices slipped $1/bbl on June 16 in volatile trading after reports that Iran is seeking an end to hostilities with Israel, raising the possibility of a truce and easing fears of a disruption to crude supplies from the region.

Brent crude futures settled $1, or 1.35%, lower to $73.23/bbl. U.S. West Texas Intermediate crude futures fell $1.21, or 1.66%, to $71.77/bbl.

Iran has asked Qatar, Saudi Arabia and Oman to press U.S. President Donald Trump to use his influence on Israel for an immediate ceasefire in return for Tehran's flexibility in talks about its nuclear program, two Iranian and three regional sources told Reuters. Earlier, the Wall Street Journal had reported Iran was seeking a truce.

Traders pared bets that bombing by both sides could turn into a broader, regional war that would threaten energy infrastructure, Mizuho analyst Robert Yawger said.

On June 13, oil prices surged more than 7% after Israel began bombing Iran over claims Tehran was close to securing an atomic bomb.

June 13's surge put oil in "overbought territory" in terms of technical indicators, which is typically followed by a downward move, said Rory Johnston, an energy analyst and founder of the Commodity Context newsletter.

"As I see it, the initial run up in prices on Thursday/Friday was fueled by a large inflow of speculative cash, which brought us back into overbought spec positioning levels," Johnston said.

"When you're in that state, the market is especially vulnerable to sharp liquidations," Johnston added.

Both Israel and Iran have traded airstrikes, including on energy infrastructure, but key oil export facilities have not yet been hit.

"The Israelis have not touched Kharg Island, so that is the story right now," Mizuho's Yawger said, referring to the Iranian oil export hub.

Yawger said any strikes on Kharg Island would likely send oil prices soaring to $90/bbl.

"It all boils down to how the conflict escalates around energy flows," said Harry Tchilinguirian, group head of research at Onyx Capital Group. "So far, production capacity and export capacity have been spared and there hasn't been any effort on the part of Iran to impair flows through the Strait of Hormuz."

Electronic interference with commercial ship navigation systems has surged in recent days around the Strait of Hormuz and the wider Gulf, which is having an impact on vessels sailing through the region, naval forces said on June 16.

About a fifth of the world's total oil consumption, or some 18 MMbbl/d to 19 MMbbl/d of oil, condensate and fuel, passes through the strait.

Iran, a member of OPEC, currently produces around 3.3 MMbbl/d and exports more than 2 MMbbl/d of oil and fuel.

The spare capacity of OPEC+ oil producers to pump more to offset any disruption is roughly equivalent to Iran's output, according to analysts and OPEC watchers.
