US tells Iran Israel won't escalate Lebanon attacks, easing crude risk

The United States told Iran that Israel will not escalate its attacks on Lebanon, according to a CNN report, a de-escalatory signal that helped push Brent crude down 9.5 percent for the week to $79.03 a barrel as oil tankers resumed passage through the Strait of Hormuz.

"The US communicated to Iran that Israel will not escalate its attacks on Lebanon," a person familiar with the matter told CNN. The message came as Vice President JD Vance postponed a planned trip to Switzerland for next-phase talks with Tehran, with the White House citing logistical issues for the delay.

Brent crude fell 1 percent on Friday to close at $79.03, capping a 9.5 percent weekly decline — the largest since mid-April. The drop accelerated after 25 commercial vessels transited the Strait of Hormuz on Thursday, the highest single-day count since April 18 and more than five times the average daily level recorded during the first 10 days of June, according to maritime tracking firm AXSMarine. The strait handles about 21 percent of global oil trade.

The de-escalatory signal comes as the US-Iran memorandum of understanding signed Wednesday faces its first major test. The agreement calls for an immediate halt to military operations "on all fronts, including in Lebanon" and 60 days of direct bilateral negotiations. But fighting between Israel and Hezbollah flared again Thursday evening, with Israel striking at least 80 Hezbollah targets across southern Lebanon and Lebanese state media reporting 18 civilians killed — the deadliest attacks since the deal was signed.

The Fragile Ceasefire

Israel said its strikes were a response to "repeated, ongoing, and blatant violations of the ceasefire" by Hezbollah, while Prime Minister Benjamin Netanyahu vowed to "exact a very heavy price from Hezbollah" for the deaths of four Israeli soldiers, including a lieutenant colonel killed by an explosive drone. He reiterated that Israeli forces would remain in a security zone in southern Lebanon "as long as necessary."

Iran's Supreme National Security Council said Friday it signed the memorandum but has "complete distrust" in the United States to uphold the agreement, warning that "any deviation or violation" would bring reciprocal action. Iran suspended plans to begin direct talks in Switzerland on Friday specifically over the fighting and Netanyahu's comments, which it described as violating the interim deal, according to two regional officials who spoke to the Associated Press.

France's foreign minister, Jean-Noel Barrot, called on the US to pressure Israel to halt hostilities, saying the agreement "involves the cessation of hostilities" and that "the Israeli government must respect it." He also called on Hezbollah to stop attacking Israel and begin a disarmament process.

Market Implications

The last time a US-brokered de-escalation in the region faced similar stress was in early 2020, when Brent crude swung more than 15 percent in two weeks after a US drone strike in Iraq before stabilizing as diplomatic channels reopened. The current setup — a signed framework facing immediate battlefield tests — leaves oil markets pricing a wide range of outcomes.

For now, the resumption of tanker traffic through the Strait of Hormuz and the US diplomatic signal have reduced the geopolitical risk premium embedded in crude. Brent's decline from late-May highs above $87 reflects growing market conviction that a broader regional war is being contained. But with Iran expressing distrust, Israel continuing operations in southern Lebanon, and next-phase talks delayed, the risk of a reversal remains elevated. Any renewed escalation could quickly erase this week's price relief.
