Oil markets jolted global financial assets on Monday as a sharp escalation in the Middle East conflict sent crude prices surging and forced governments and investors to reassess the economic fallout from a potential supply shock.
Brent crude briefly climbed to $119.50 a barrel while U.S. West Texas Intermediate touched $119.48, marking the strongest intraday levels since mid-2022 and putting Brent on track for one of its largest single-day advances on record. The rally was driven by mounting concerns over disrupted production and shipping routes across the Persian Gulf, particularly the Strait of Hormuz, a critical artery through which roughly a fifth of the world’s oil supply moves.
The spike in crude prices came as several major regional producers — including Iran, Iraq, Kuwait, and the United Arab Emirates — began reducing production amid rising operational risks and storage constraints. Analysts warned that the situation could tighten global supplies further if the conflict deepens or shipping disruptions intensify.

“The violent reaction stems from the markets seeing no obvious offramp in the escalating Middle East conflict, now a high-stakes standoff where neither side appears willing to blink first,” IG market analyst Tony Sycamore said in a note. “The risk of more lasting economic damage continues to build by the day.”
The geopolitical escalation coincided with a political development in Tehran. Iran announced that Mojtaba Khamenei will succeed his father, Ali Khamenei, as Supreme Leader, signaling continuity in the country’s hardline leadership as tensions with the United States and Israel intensify.
The oil surge rippled through global commodity markets. Agricultural products rallied sharply as traders anticipated stronger demand for biofuel feedstocks tied to higher crude prices. Malaysian palm oil jumped about 9% while Chicago soybean oil climbed to its highest level since late 2022. Wheat futures rose to their highest since June 2024, and corn prices reached a 10-month peak.
Industrial metals showed a mixed response. Aluminium surged to its strongest level in four years, with benchmark three-month contracts on the London Metal Exchange hitting $3,544 per metric ton. Supply fears intensified after regional smelters such as Qatalum in Qatar and Aluminium Bahrain declared force majeure on shipments amid rising regional instability.
Other base metals, however, faced pressure from currency dynamics as the U.S. dollar strengthened. The greenback hovered near a three-month high, supported by rising U.S. Treasury yields and fading expectations for near-term interest-rate cuts.
The stronger dollar also weighed on precious metals. Gold fell more than 2% despite the geopolitical turmoil that typically boosts demand for safe-haven assets. Analysts said the decline reflected the combined impact of a stronger dollar, rising yields, and mounting concerns that higher energy prices could prolong global inflation.
Indeed, the oil rally immediately reverberated through bond markets. U.S. Treasury yields climbed as investors braced for renewed inflation pressure stemming from higher energy costs. Markets increasingly expect central banks to maintain tighter monetary conditions for longer if crude prices remain elevated.
Governments around the world have begun scrambling to cushion the economic impact of the energy shock.
Vietnam said it is planning to temporarily remove import tariffs on fuel products to secure adequate supplies amid disruptions linked to the Middle East conflict. The tariff suspension, expected to run through the end of April, is being prepared by the Ministry of Finance, according to a government statement issued late Sunday.
In West Africa, supply concerns are also emerging. Nigeria’s Dangote Petroleum Refinery suspended petrol loading operations over the weekend of March 7–8, highlighting logistical difficulties in maintaining a stable domestic supply during a period of volatile global crude markets. The disruption raised fears of renewed fuel shortages in Africa’s largest economy.
To stabilize supply, the Nigerian government — through the Nigerian National Petroleum Company Limited — has moved to secure crude feedstock for the refinery via third-party international traders. Ensuring reliable crude allocation to the facility is seen as critical to maintaining local refining output and preventing petrol scarcity across Nigeria and parts of the broader West African market.
In Asia, South Korea is considering direct price intervention for the first time in decades. President Lee Jae Myung said Seoul will “swiftly introduce” a fuel price cap to shield consumers from soaring energy costs, marking the country’s first such measure in roughly 30 years. The government is also exploring ways to diversify its energy import sources to reduce vulnerability to Middle East supply disruptions.
The wave of policy responses highlights how quickly the geopolitical crisis is translating into economic risk. Higher energy costs threaten to ripple through transport, manufacturing, and food supply chains, raising the prospect of a renewed global inflation shock just as many economies were beginning to stabilize.
For financial markets, the key uncertainty now is the duration of the conflict and the extent to which energy infrastructure or shipping lanes could be affected. Any prolonged disruption in the Strait of Hormuz, one of the world’s most strategically vital energy corridors, would amplify supply shortages and could push crude prices significantly higher, with broad consequences for global growth and monetary policy.
