In a stark warning to the global oil market, Saudi Arabia’s state-owned oil company, Aramco, has alerted stakeholders to the potentially disastrous ramifications of an ongoing blockade in the Strait of Hormuz. As tensions escalate with Iran amid the US-Israel conflict, oil shipments through this critical maritime route have been severely hampered, with Aramco’s chief executive indicating that the situation could lead to “catastrophic consequences” for the world economy.
Current Shipping Blockade and Its Impact
The Strait of Hormuz, a vital conduit for approximately one-fifth of the world’s oil and liquefied natural gas, has experienced a dramatic reduction in tanker traffic. Since the US military strikes on Iran 11 days ago, the number of vessels transiting the strait has dwindled to single digits, representing a significant decline from the typical daily average of 100. This blockade has effectively removed around 20 million barrels of oil per day from the global supply, thereby creating a precarious situation for energy markets.
Despite this disruption, Aramco maintains that it can manage to deliver approximately 70% of its regular crude output by rerouting through the east-west pipeline to the Red Sea port of Yanbu. This logistical pivot is expected to enable the company to meet customer demands, with projections of reaching full pipeline capacity of 7 million barrels per day in the coming days. However, Amin Nasser, Aramco’s CEO, cautioned that the situation remains critical, stating, “the longer the disruption goes on…the more drastic the consequences for the global economy.”
Market Reactions and Price Fluctuations
Interestingly, oil prices saw a decline on Tuesday despite the dire warnings, largely attributed to remarks from former US President Donald Trump suggesting a potential swift resolution to the conflict. The price of Brent crude, the international benchmark, fell by 14%, settling around $85 per barrel. While this is a decrease from the peak of $119 earlier in the week—the highest since Russia’s invasion of Ukraine—it remains considerably above pre-crisis levels of $72.

Simultaneously, stock markets on both sides of the Atlantic experienced a relief rally. The FTSE 100 increased by 1.6%, while Germany’s DAX and France’s CAC saw gains of 2.4% and 1.8%, respectively. US markets also exhibited positive trading sentiments, signalling a complex interplay between geopolitical tensions and investor confidence.
Global Responses and Strategic Stockpiling
In response to the escalating crisis, leaders of the G7 have urged the International Energy Agency (IEA) to prepare contingency plans for the release of emergency oil stockpiles. Although they did not authorise an immediate stock release—something that has only occurred five times in IEA history—the discussions signal a recognition of the potential need for intervention.
The IEA mandates its 32 member countries to maintain a reserve of at least 90 days’ worth of emergency crude supplies. Currently, IEA members collectively hold over 1.2 billion barrels in public reserves, alongside an additional 600 million barrels in industry stocks held under government obligations. Notably, China, the world’s largest energy importer and an IEA non-member, is believed to have up to 1.4 billion barrels in storage, further contributing to the global supply landscape.
Why it Matters
The situation in the Strait of Hormuz is emblematic of the intricate balance between geopolitical stability and global energy security. As Aramco’s warnings illustrate, the ramifications of a sustained blockade could ripple through economies worldwide, affecting everything from consumer prices to inflation rates. The potential for intervention by global leaders highlights the fragility of the current oil market, where even the slightest disruption can provoke significant volatility. For businesses and consumers alike, the stakes are high, making it imperative to monitor developments closely as the situation unfolds.
