A fresh wave of positive headlines from the Middle East sent the euro and sterling higher while crude oil prices tumbled, marking the sharpest one-day reversal in risk sentiment in weeks.
The euro and sterling rallied against the dollar on Sunday as reports of progress toward a ceasefire between the US and Iran fueled expectations that the conflict disrupting two of the world's most vital energy chokepoints may be nearing a resolution. Brent crude, the global benchmark, slid sharply below $95 a barrel, extending a weekly decline that had already erased more than 12% from the previous week's close near $100.69.
"The market is pricing in a material de-escalation probability that simply didn't exist 72 hours ago," said Elena Fischer, geopolitical risk analyst at Edgen. "If the Strait of Hormuz and Bab el-Mandeb return to normal transit, we're looking at a supply restoration of roughly 17 million barrels a day — that's a game-changer for inflation expectations across Europe and the UK."
The move lower in energy prices accelerated after Brent had touched $102 a barrel on Thursday, its highest settlement since May 22, before closing at $100.69. The subsequent slide below $95 represents a decline of more than 5% from that level. The US 3-2-1 crack spread — the margin from refining three barrels of crude into two barrels of gasoline and one barrel of diesel — had climbed to a record near $70 a barrel earlier in the week, signaling acute product shortages that are now expected to ease if supply routes reopen.
What a ceasefire would unlock
The Strait of Hormuz and the Bab el-Mandeb Strait together carry the equivalent of roughly a quarter of the world's oil supply. Traffic through both chokepoints had been severely restricted since February, when renewed US-Iran hostilities escalated into a broader regional conflict involving Houthi attacks on Red Sea tankers and a naval blockade against Saudi Arabia. The disruption pushed Brent to a four-year high of $126.41 a barrel in April before a temporary ceasefire memorandum and strategic reserve releases brought prices back down.
This time, however, the buffer is far thinner. The US Strategic Petroleum Reserve stands at roughly 311 million barrels, its lowest level since 1983, leaving limited room for another emergency drawdown. Commercial oil inventories and floating storage have also been depleted rapidly, the International Energy Agency warned in May, leaving only a few weeks' worth of supply.
Goldman Sachs had warned that Brent could exceed $120 a barrel in the fourth quarter if disruptions continued, while JPMorgan calculated each additional month of supply disruption could add $7 to $8 a barrel. Those scenarios now appear less likely if the current diplomatic track holds.
Currency and inflation implications
For the euro and sterling, lower energy prices offer a direct tailwind. Both currencies had been under pressure as surging fuel costs pushed inflation expectations higher, complicating the European Central Bank and Bank of England's policy paths. European diesel crack spreads had climbed to around $65 a barrel, signaling an acute shortage of the fuel used by industry and heavy transport, while the US national average retail diesel price surpassed $5.13 a gallon, up from pre-war levels of $3.53.
A sustained decline in oil prices would ease those pressures, potentially allowing both central banks to adopt a more dovish stance. The ECB had been grappling with the risk that energy-driven inflation would delay its rate normalization plans, while the BoE faced similar headwinds from diesel and jet fuel costs that had pushed the global average jet fuel price to $149.40 a barrel as of July 17.
The last time a similar diplomatic breakthrough occurred — the temporary US-Iran ceasefire memorandum in June — Brent retreated from above $120 to below $70 over the following months, and both the euro and sterling gained more than 5% against the dollar during that period. Whether this latest round of headlines produces a comparable outcome depends on whether the reported progress translates into a formal agreement, something that remains uncertain.
For now, markets are betting on peace. The question is whether Sunday's risk-on move holds when Asian and European cash trading opens Monday.
