Global oil markets are experiencing a significant spike following recent military actions involving Iran and an alarming escalation of regional tensions. On Monday, Brent crude surged by 4.5 per cent, reaching $76.07 (£60) a barrel, shortly after crossing the $82 (£65) mark. In parallel, US crude oil prices increased by 3.9 per cent, reflecting the broader anxiety gripping the market as fears mount over a potential long-term closure of the strategically vital Strait of Hormuz.
Iranian Attacks Threaten Global Oil Supply
The price surge comes in the wake of assertions from Iran’s Islamic Revolutionary Guard Corps (IRGC) claiming responsibility for attacks on three oil tankers linked to the US and UK in the Gulf region. Coupled with missile and drone assaults on military installations and civilian infrastructure, these developments have sent ripples through the shipping industry. Vessel tracking data indicates that numerous oil and gas tankers are now anchoring in nearby waters, as traders prepare for possible further disruptions.
An official from the European Union’s naval mission, Aspides, disclosed to Reuters that Iranian forces communicated via VHF radio, warning that “no ship is allowed to pass the Strait of Hormuz.” While Tehran has yet to formally confirm any such directive, the country’s historical threats to obstruct this crucial waterway, through which approximately 20 per cent of the world’s crude oil flows, have raised alarm bells.
Market Reactions and Forecasts
The immediate ramifications for the oil market are stark. Jorge Leon, head of geopolitical analysis at Rystad Energy, stated, “The most immediate and tangible development affecting oil markets is the effective halt of traffic through the Strait of Hormuz, preventing 15 million barrels per day of crude oil from reaching markets.” He added that without swift signs of de-escalation, a significant increase in oil prices is likely imminent.

Analysts at Goldman Sachs echoed these concerns, indicating that if shipping through the Strait were to cease for a month, European natural gas prices could more than double. Their analysis suggests that such a disruption could elevate prices for Asian spot liquefied natural gas (LNG) by as much as 130 per cent, reaching around $25 (£20) per million British thermal units. A protracted halt lasting over two months could push European prices above €100 (£85) per megawatt hour, potentially leading to considerable demand destruction.
Vaibhav Chaturvedi, a senior fellow at the Council on Energy, Environment, and Water, noted the precarious implications of a US-Iran conflict on the global energy landscape. He warned of an impending rise in oil prices in the short term, with longer-term consequences likely to adversely affect the global economy if hostilities persist.
Historical Context and Future Outlook
The current scenario bears resemblance to the oil embargoes of the 1970s, which saw prices surge by approximately 300 per cent. Alan Gelder, a senior vice president at Wood Mackenzie, remarked that today’s market conditions could easily eclipse those historical price hikes, given the current climate of uncertainty surrounding supply.
John Gong, a professor at the University of International Business and Economics in Beijing, emphasised the severe implications of a strait closure. He described such an action as “totally unacceptable,” foreseeing detrimental effects on countries like China, Japan, and South Korea, which are heavily reliant on Middle Eastern oil supplies. China, in particular, imports an estimated 1 to 1.5 million barrels of Iranian crude daily, which could face significant challenges under tighter enforcement or conflict.
The economic fallout is not limited to these nations. Vivek Y Kelkar, a researcher focusing on geo-economics, highlighted that India, with its 90 per cent dependence on oil imports, is particularly vulnerable. He estimated that every $10 (£8) increase in oil prices could inflate India’s annual import bill by approximately $13–14 billion (£10–11 billion).
OPEC+ Response and Regional Market Impact
In a bid to mitigate price surges, OPEC+ countries have agreed to increase production by 206,000 barrels per day starting in April. However, the effectiveness of this additional supply is hampered by the reality that much of it would also need to traverse the Gulf, limiting immediate relief if shipping disruptions continue.

The economic strain from the conflict is already evident in the Gulf region. In response to Iranian strikes impacting airports and ports, the United Arab Emirates has ordered stock markets closed for two days. Meanwhile, Saudi Arabia’s benchmark index plummeted over 4 per cent, with Oman and Kuwait also experiencing significant market declines.
Why it Matters
The escalating tensions in the Strait of Hormuz underscore a critical juncture for the global energy economy, with the potential for sustained disruptions to oil and gas supplies threatening to reverberate through international markets. As nations scramble to secure energy resources and navigate rising costs, the geopolitical landscape of the Middle East remains precarious. The outcome of this conflict could reshape energy dynamics and economic stability not only within the region but across the globe, impacting consumers and industries alike.
