Oil Tumbles 5% as US-Iran Peace Talks Fuel Market Shift

(P1) A sharp drop in oil prices and a rally in risk assets are accelerating after reports that the United States and Iran are in the “final stages” of a deal, a development that could reopen the critical Strait of Hormuz and unwind months of geopolitical risk premium. Brent crude, the international benchmark, tumbled 5.1% to $105.15 a barrel, its largest one-day drop in over a year.

(P2) "While oil prices tumbled on Tuesday after Trump said the US is in the 'final stages' with Iran, physical markets remain 'in disarray,' with 55-day Persian Gulf-to-destination transit times meaning inventories continue to draw," Rabobank said in a note, highlighting the lingering supply chain challenges even if a deal is reached.

(P3) The market reaction was swift and broad-based. Along with the slide in oil, US Treasury yields retreated, with the 10-year note falling 8 basis points to 4.58%. This relief in borrowing costs helped fuel a rally in equities, with the S&P 500 climbing 1.1% and the tech-heavy Nasdaq Composite adding 1.5%. Haven assets saw a mixed reaction; gold bounced 1.3% from a two-month low to $4,543 an ounce, but the US Dollar Index was testing key technical levels.

(P4) The potential breakthrough in negotiations puts the significant geopolitical risk premium built into asset prices at risk. A confirmed reopening of the Strait of Hormuz, a chokepoint for about a fifth of the world's oil supply, would likely lead to a sustained period of lower energy prices. This could provide a tailwind for global growth and ease inflationary pressures, but it would also unwind profitable trades for investors who have been long energy and defense stocks for months.

Markets Reprice Geopolitical Risk

The shift in sentiment began after former President Trump, in a statement Tuesday, said planned military strikes were cancelled at the request of Gulf state leaders who assured a deal was near. This was followed by reports from Bloomberg that a South Korean supertanker, along with two Chinese vessels, was attempting a crossing of the Strait of Hormuz, a sign of tentatively improving flows.

The news sent a shockwave through energy markets. In addition to Brent’s slide, stocks across the energy complex sold off. Woodside Energy Group (ASX: WDS) fell 2.03%, Santos (ASX: STO) dropped 1.05%, and coal producer Stanmore Resources (ASX: SMR) declined 4.02%. The move lower comes after months of elevated prices. Goldman Sachs recently estimated that global oil inventories were being drawn down at a record pace of 8.7 million barrels per day in May.

Havens Retreat as Risk Appetite Returns

The drop in oil and the prospect of lower inflation sparked a rally in risk assets. The S&P/ASX 200 in Australia jumped 1.51%, with yield-sensitive sectors like Real Estate leading the gains. In the US, airline stocks caught a bid on the prospect of lower fuel costs, with Delta Air Lines (NYSE: DAL) also getting a boost from news that Berkshire Hathaway had built a significant stake.

The move is a reversal of the trend seen for most of the year, where spiking yields and war-driven oil gains threatened to choke off growth. The easing of tensions, if it holds, could provide central banks with more flexibility. The April FOMC minutes showed a clear hawkish shift, with officials open to rate hikes if inflation persisted. A sustained fall in energy prices would alleviate some of that pressure. The last time a similar geopolitical shock in the Gulf unwound, during the 1990-91 Gulf War, oil prices fell by over 30% in the subsequent three months.
