Oil Rallies as Iran Halts Talks and Israeli Forces Advance in Lebanon

Oil markets convulsed on Monday as Iran abruptly suspended all communication with the United States, scuttling hopes of a lasting ceasefire and sending crude futures sharply higher. Brent crude, the international benchmark, spiked as much as 6.9 per cent to $97.40 a barrel in late European trading, while West Texas Intermediate surged 8.1 per cent to $94.47. The trigger, reported by the Tasnim news agency close to Iran’s Revolutionary Guards, was the breakdown of indirect talks after Israeli forces intensified operations in southern Lebanon, a condition Tehran had insisted must be part of any settlement. “As long as Israel does not leave occupied territories in Lebanon and halt operations in Gaza, there will be no negotiations,” the agency stated.

The escalation caught markets off guard, reversing much of the optimism that had driven a 19 per cent slump in Brent over May. Only two weeks earlier, Washington and Tehran had agreed to prolong a ceasefire originally brokered in mid-April for an additional 45 days. Over the weekend, however, the US and Iran traded military strikes – Washington targeted radar and command facilities, while Tehran-backed groups retaliated – and Israel ordered ground forces to advance against Hezbollah positions. From Tehran’s perspective, the American inability to restrain its ally rendered the diplomatic track meaningless. In the Persian Gulf, nerves frayed further after Iranian officials threatened to block the Strait of Hormuz and the Bab el-Mandeb waterway, through which a fifth of global oil supply passes.

Yet the rally lost steam after President Donald Trump told reporters that discussions with Iran were still “advancing rapidly”, contradicting the Iranian narrative. By the close, Brent had settled at $94.98 a barrel, a gain of 4.2 per cent, well off its intraday peak. Analysts in London noted that the wild swings reflected a market grappling with two irreconcilable messages: from Washington, a promise of imminent diplomacy; from Tehran and the battlefield, an accelerating cycle of violence. The divergence left traders betting on a prolonged risk premium, especially given the lingering threat to chokepoints.

Beyond the immediate price moves, the episode underscores the brittleness of the wider Middle Eastern security architecture. The April ceasefire had offered a fragile respite, but it failed to address the underlying drivers of conflict – Israel’s multi-front campaigns, Iran’s regional network of militias, and the absence of a binding framework for de-escalation. With Brent still far below the $114 a barrel touched in early April, the market is priced for disruption, not catastrophe. Yet any sustained closure of Hormuz, however unlikely, would upend those calculations. For now, the onus rests on diplomatic channels that appear, for the moment, severed.
