Global financial markets experienced a dramatic shift on Wednesday as hopes for a diplomatic breakthrough between the United States and Iran ignited a powerful rally in equities and sovereign bonds while sending oil prices plummeting over 8%. A report from Axios indicated that Washington and Tehran are moving closer to a one-page memorandum that could potentially end the war, with the U.S. awaiting Iranian responses on several key points within the next 48 hours. Although no final agreement has been reached, sources described the current stage as the closest the two sides have come to a deal since the conflict began.
European stock markets led the charge, with the broad STOXX 600 index climbing 2.2%. Economically sensitive sectors such as banks and mining companies posted outsized gains, while oil and gas stocks fell in tandem with crude prices. The risk-on mood was further amplified by a sharp decline in bond yields. The benchmark U.S. 10-year Treasury yield dropped 6 basis points to 4.35%, and Germany's 10‑year yield fell 7.5 basis points to 2.99%, as traders scaled back expectations for aggressive interest rate hikes from the European Central Bank. British gilt yields tumbled 10 basis points and Italian yields declined 12.5 basis points, reflecting broad-based demand for sovereign debt.
On the currency front, the U.S. dollar weakened, with the euro advancing 0.6% to $1.1762 and the British pound gaining 0.6% to $1.3618. The dollar's slide underscored a rotation out of defensive positions as geopolitical risks appeared to recede.
The most violent move came in crude oil. Brent crude, traded on the ICE, plunged 8.1% to $101 per barrel, while West Texas Intermediate cratered 9.2% to $92.86. Both benchmarks were on track for their largest daily percentage and absolute declines since mid‑April, compounding a 4% sell‑off in the previous session. The Strait of Hormuz, a vital chokepoint that has seen marine traffic halted since the war began in February, has disrupted roughly 13 million barrels per day of supply. According to ING Economics, inventories are visibly and quickly diminishing, leaving the market “more vulnerable with each passing day” and prone to heightened volatility, as noted by Warren Patterson, head of commodities strategy at ING.
U.S. inventory data added to the supply‑side concerns. The American Petroleum Institute reported a massive 8.1-million-barrel draw in crude stocks, alongside declines of 6.1 million barrels in gasoline and 4.6 million barrels in distillate inventories. Gasoline stocks now sit at just over 222 million barrels, the lowest level for this time of year since 2014, while distillate stocks are below 104 million barrels, the weakest since 2005. Patterson warned that such tightness would keep refined product cracks trading at elevated levels.
The diplomatic shift was further confirmed when President Donald Trump announced a pause to “Project Freedom” — the military escort strategy for commercial vessels through the Strait of Hormuz — while the U.S. pursues a “complete and final agreement.” Trump characterized the progress as “great,” injecting fresh optimism into markets that have been rattled by months of conflict. As Patterson emphasized, “Looking ahead, developments in the Middle East will remain key to price direction,” and restoring normal oil flows through the strait is essential to stabilize markets.
