The ongoing conflict between the US and Israel against Iran has raised alarm bells in the oil market, with Saudi Aramco warning of severe repercussions if the situation continues to disrupt shipping through the strait of Hormuz. The state-owned oil giant has indicated that while it can still manage to supply approximately 70% of its usual crude exports, the broader implications for the global economy could be dire if the blockade persists.
Shipping Disruptions Create a Supply Crisis
The strait of Hormuz, a vital passage for oil transportation, has seen a dramatic decrease in tanker traffic since US airstrikes targeted Iranian interests 11 days ago. With the waterway being responsible for the transit of about a fifth of the world’s oil and liquefied natural gas, the blockade has effectively removed 20 million barrels per day from global circulation. This disruption has led to heightened concerns over energy prices and market stability.
Despite the turmoil, oil prices experienced a surprising decline on Tuesday following comments from former US President Donald Trump, who suggested that hostilities might end soon. The price of Brent crude fell by 14%, settling at around $85 a barrel, although this figure remains elevated compared to the $72 recorded prior to the military actions. The spike earlier in the week saw prices peak at $119, the highest since Russia’s invasion of Ukraine in 2022, further intensifying fears of an economic downturn.
Aramco’s Response and Market Strategies
Amin Nasser, Aramco’s chief executive, highlighted the gravity of the current crisis, stating, “While we have faced disruptions in the past, this one by far is the biggest crisis the region’s oil and gas industry has faced.” In response to the blockade, the company is ramping up shipments via its east-west pipeline to the Red Sea port of Yanbu, aiming to maximise output to its full capacity of 7 million barrels per day in the coming days.

From this capacity, around 2 million barrels will be directed to domestic refineries, leaving 5 million barrels available for international markets. This strategy is crucial as the number of tankers navigating the strait has plummeted from approximately 100 per day to mere single digits, following threats from Iran’s Islamic Revolutionary Guard Corps against vessels using the route.
Global Responses and Strategic Reserves
In light of the escalating crisis, leaders of the G7 nations have called on the International Energy Agency (IEA) to explore options for releasing emergency oil stockpiles to stabilise the market. However, they have yet to authorise any stock releases, an action that has only occurred five times in the history of oil markets.
The IEA mandates that its 32 member countries maintain a minimum of 90 days’ worth of emergency crude supplies, totalling more than 1.2 billion barrels in public reserves. Additionally, China, which is not an IEA member, is estimated to hold record-high levels of crude, potentially up to 1.4 billion barrels.
The prospect of coordinated action to mitigate the volatility has provided some relief to the markets, with Brent crude settling below $90 a barrel by the end of the trading day. This development highlights the precarious balance between supply and demand amid geopolitical tensions.
Why it Matters
The implications of the ongoing US-Israel conflict with Iran extend far beyond regional borders, threatening to disrupt global oil supplies and, consequently, the world economy. As energy prices fluctuate, the potential for inflation and economic instability increases. With Aramco’s warning of “catastrophic consequences” should the situation persist, the need for strategic intervention becomes critical. The ability of global leaders to respond effectively to this crisis may define the landscape of international energy markets for years to come.
