The core event dominating global financial markets is the ongoing war between the United States and Iran, which has led to significant volatility in oil prices and broad market uncertainty. Asian equity markets were mostly higher on Wednesday, with Tokyo's Nikkei 225 up 1.3% and South Korea's Kospi gaining 0.6%, though both gave up some early gains as investors awaited clarity on the war's duration and potential end [1]. Oil prices, which had spiked to nearly $120 per barrel—the highest since 2022—plunged Monday after U.S. President Donald Trump told CBS News he believed 'the war is very complete, pretty much,' raising hopes for a swift resolution [1]. However, both sides have since escalated their rhetoric, with U.S. Defense Secretary Pete Hegseth promising the most intense strikes yet and the U.S. military reporting the destruction of more than a dozen Iranian minelaying vessels near the Strait of Hormuz [1][3][10]. Iran has vowed to block oil exports, stating it would not allow 'even a single liter' to be shipped to its enemies [1][7].
Oil prices have remained volatile, with Brent crude trading at $87.78–$88.39 per barrel and U.S. crude at $83.76–$84.55 per barrel on Wednesday, about 10% below Monday's peak but still up over 40% year-to-date [1][3][9][10][8]. The International Energy Agency (IEA) has proposed the largest-ever release of oil from its strategic reserves, exceeding the 182 million barrels released in 2022, in an effort to stabilize markets [3][5][7][9]. IEA Executive Director Fatih Birol noted that member countries hold over 1.2 billion barrels of public emergency oil stocks, with an additional 600 million barrels in industry stocks [9]. G7 energy ministers convened in Paris to discuss the crisis, and countries are set to decide on the emergency release [9]. Market analysts, including Sasha Foss of Marex, warn that such releases may only buy a few days of relief, with the true resolution hinging on the reopening of the Strait of Hormuz; a prolonged conflict could push oil prices back above $100 per barrel [9][7].
The war's impact on monetary policy is significant. Commerzbank's Antje Praefcke argues that U.S. inflation data is unlikely to move the dollar in the near term, as oil and the Iran war dominate market focus [2]. If the conflict is resolved quickly, central banks may view the oil price spike as temporary, but a prolonged war could force the Federal Reserve to keep rates 'high for longer,' with markets already postponing expectations for rate cuts [2][8]. DBS notes that U.S. CPI is expected at 2.4% year-on-year for February, but elevated oil prices and higher 2-year breakevens (up 70bps year-to-date, now near 3%) are constraining Fed easing, with fewer than two rate cuts priced for 2026 [8]. The ECB's Peter Kazimir stated that a rate hike 'may be closer than thought' due to upside inflation risks from the Iran war [4]. In the UK, expectations for Bank of England rate cuts have been delayed, with markets now pricing a 98% probability of no change this month and the terminal rate forecast at 3.25% by end-2026 [5].
Currency markets have responded to these developments. The U.S. dollar has struggled for demand, particularly against the Australian dollar, and remains subdued ahead of U.S. CPI data [3][5][6]. The pound sterling has strengthened on optimism that the Middle East conflict may have a smaller inflationary impact than initially feared, aided by the prospect of the IEA's oil reserve release and Trump's comments about a possible quick end to the war [5]. The USD/CAD pair remains under pressure, with the Canadian dollar supported by expectations that oil prices are no longer high enough to limit Fed rate cuts [6].
Equity markets have been volatile, with U.S. stocks ending mixed as traders weighed the oil price pullback against the risk of further escalation [10]. Semiconductor stocks, including SK Hynix and Samsung, have been particularly affected, losing over $200 billion in combined value since the war began, though both rallied sharply on Tuesday [10]. Analysts warn that a prolonged conflict could impact the semiconductor industry's access to key materials and raise costs, potentially hitting demand for chips central to the AI boom [10].
Despite some market optimism following Trump's comments, the situation remains highly uncertain. The Strait of Hormuz remains effectively closed for most global oil supply, though TankerTrackers and Kpler report that 11.7–12 million barrels of oil have passed through since the war began [10]. The IEA's proposed emergency oil release may provide temporary relief, but the market's focus remains on the war's duration and the reopening of critical shipping routes [7][9][10].
CONCLUSION
The ongoing U.S.-Iran war has caused extreme volatility in oil and financial markets, with prices swinging sharply on hopes for a quick resolution but remaining elevated due to persistent supply risks. Central banks are delaying or reconsidering rate cuts amid inflation concerns, and equity and currency markets remain sensitive to developments in the conflict. The market's outlook hinges on the war's duration and the reopening of the Strait of Hormuz, with emergency oil reserve releases offering only temporary relief.
