The Strait of Hormuz remains effectively closed, posing a severe threat to global energy supplies that could have far-reaching economic implications. This critical maritime chokepoint, responsible for transporting approximately 20% of the world's oil and liquefied natural gas, is experiencing significant disruptions due to heightened geopolitical tensions. The closure has already led to a disruption of around 10 million barrels of oil per day, surpassing the impact of the 1973 Arab oil embargo. Energy analysts have modelled scenarios in which a sustained closure could remove between 8 and 10 million barrels per day from global circulation, representing roughly one-tenth of worldwide supply almost immediately. The situation is exacerbated by the withdrawal of insurance coverage and shipping operators' reluctance to navigate the strait, driven by increased risk perceptions. Despite military efforts to secure passage, the commercial and insurance sectors remain unconvinced, leading to a de facto shutdown of the route. Iran has now announced plans to make ships pay to use the Strait of Hormuz, adding another layer of complexity to the already volatile situation. Recent developments show that stock markets in the Gulf ended lower on Sunday as comments from U.S. President Donald Trump and Iran's foreign minister further dimmed hopes of a deal to end ship attacks and seizures near the strait.
International oil inventories are showing concerning declines according to major financial institutions. UBS reports that international oil inventories stood at a little over 8 billion barrels at the end of February, dropping to around 7.8 billion barrels by the end of April. The bank estimates that if demand trends continue, stocks could fall further to nearly 7.6 billion barrels by the end of May. The International Energy Agency's latest oil market report reveals that observed global oil stocks have declined by a cumulative 246 million barrels since the conflict began, representing nearly one full week of worldwide oil consumption. JPMorgan Chase has also flagged risks to international supply chains as inventories decline, estimating that only around 800 million barrels of stocks can be used without creating pressure on supply systems, as the remaining reserves are required to keep pipelines and storage infrastructure running smoothly.
Industry leaders are expressing growing concern about the sustainability of current supply buffers amid the escalating crisis. During Exxon Mobil's first quarter earnings call, Chief Executive Darren Woods noted that commercial stocks, government strategic reserves and oil in transit helped absorb some of the supply shock in March and April. However, Woods warned that if commercial inventories continue to fall while the Strait of Hormuz is disrupted, prices in the market could rise further. Rapidan Energy has assessed that refined product inventories could reach critical levels by July or August if present conditions continue, warning that such a situation could affect international economic activity, especially sectors that depend heavily on transport fuel. In an extreme scenario where Hormuz throughput is severely curtailed for an extended period, Brent crude could approach or exceed the $100 per barrel threshold that multiple energy analysts have identified as a realistic ceiling under sustained supply removal of 8 to 10 million barrels per day.
Africa faces disproportionate exposure to the Strait of Hormuz crisis due to its heavy reliance on Middle Eastern refined fuel imports. The continent imports approximately two-thirds of its total fuel demand, meaning equivalent supply losses translate into far more severe economic consequences than European economies that produce close to 80% of their fuel requirements domestically. According to the latest analysis, Africa's fuel import allocation has been reduced from approximately 800,000 barrels per day to an estimated 370,000 barrels per day during the crisis period. The compounding effects are particularly severe as fertilizer shipments transiting the Hormuz corridor reportedly declined by as much as 92% between February and March, creating a supply shock that threatens agricultural productivity across sub-Saharan African economies. However, one significant structural development has emerged: West African fuel exports surged to approximately 145,000 barrels per day during the crisis period, more than double the preceding three-month average, driven substantially by expanded output from Nigeria's Dangote Refinery. The IEA notes that Middle Eastern fuel exports to international markets have dropped sharply, with Africa accounting for roughly 800,000 barrels per day compared to 440,000 barrels per day supplied to Europe in 2025, but exports fell to just 700,000 barrels per day in April as supply disruptions intensified.
Analysts are pointing to potential economic consequences of the supply tightening and escalating crisis. Before reaching extreme shortage levels, rising fuel prices may begin to reduce demand on their own. Higher costs could slow consumption across transport and industrial sectors, easing constraints on inventories but adding strain to economic growth. The situation highlights the delicate balance between maintaining adequate energy supply and managing costs that could impact broader economic activity across multiple sectors. For Africa's commodity exporters, rising production costs erode export competitiveness at precisely the moment when global commodity prices may otherwise be elevated, creating an awkward offset dynamic for resource-sector revenues. The current crisis potentially represents the most severe energy supply disruption since the 1970s, with the structural reforms required to meaningfully reduce African exposure to Middle Eastern supply chains becoming increasingly urgent as the vulnerability mapping reveals the continent's heavy dependence on refined petroleum products rather than crude oil.
