The world’s emergency oil stockpiles, deployed at record scale to cushion the shock from the Strait of Hormuz closure, are approaching a critical threshold that analysts say will be reached in approximately two to three weeks, making mid-April the pivotal window for either a diplomatic resolution or a sharp escalation in global energy costs.
Oil industry executives and market analysts have converged on a view that the Strait of Hormuz must be reopened by mid-April or the supply disruption will intensify materially, as the stopgap measures now holding prices in check begin to expire simultaneously. The warning reflects an arithmetic reality that is increasingly difficult to dismiss: the emergency releases, the temporary sanctions exemptions on Russian and Iranian oil, and the rerouting options available to Gulf producers are all time-limited instruments, and their combined effect is now being measured in weeks rather than months.
According to geopolitical strategist Marko Papic of markets advisory firm BCA Research, the global oil market will hit a supply cliff in mid-April when releases from the Strategic Petroleum Reserve (SPR), as well as Russian and Iranian oil exempted from sanctions, run out simultaneously. There is no comparable substitute for oil pumped directly from the ground and delivered to buyers, and the industry’s ability to resume normal delivery is itself in question because Gulf producers have had to shut in production as storage fills and tankers remain unable to transit the strait.
The International Energy Agency (IEA) has described the disruption caused by the war as the greatest global energy security challenge in the agency’s history. Crude and oil product flows through the Strait of Hormuz have collapsed from around 20 million barrels per day before the conflict began to a trickle, and with limited capacity to bypass the waterway and storage filling rapidly, Gulf countries have collectively cut oil production by more than 11 million barrels per day.
The IEA coordinated the largest emergency reserve release in its 52-year history on March 11, committing 400 million barrels from member nations’ stockpiles. The United States alone committed 172 million barrels from its SPR over 120 days. Analysts at Macquarie estimated that the 400 million barrels represent roughly 16 days of normal Gulf transit volume, underlining the scale of the gap between the buffer deployed and the supply lost.
JPMorgan Commodities Research calculated that the coordinated release amounts to approximately 1.2 million barrels per day, noting this is roughly the maximum rate the system can manage, and that the volume is insufficient to counter the potential loss of approximately 12 million barrels per day from a prolonged Hormuz shutdown.
Brent crude ended trading on Friday at $103.14 per barrel, having surged to nearly $120 earlier in the month as fears of infrastructure damage and production shutdowns intensified before settling back as emergency reserves reached the market and diplomatic signals briefly lifted sentiment.
Commonwealth Bank of Australia mining and energy commodities research director Vivek Dhar warned that if physical shortages emerge once emergency buffers are exhausted, prices may need to surge sharply to curb demand particularly in developing economies with Brent potentially rising to between $120 and $150 per barrel to force the demand destruction required to bring the market back into balance.
The resolution path remains genuinely uncertain. The White House has described the outlook as improving, with an official saying the prospects of an agreement are becoming clearer, while also noting that US forces are repositioning in the region. President Donald Trump has simultaneously signalled both a willingness to strike Iran’s Kharg Island oil export facility and a preference for a negotiated outcome. That dual posture has kept options markets volatile, with traders pricing scenarios from a near-term diplomatic settlement to a prolonged closure extending through the northern hemisphere summer.
Kuwait Petroleum Corporation’s Chief Executive Sheikh Nawaf al-Sabah said at a recent energy conference that even after hostilities end, Gulf producers could require three to four months to return to full production as shut-in wells are brought back online, meaning the supply recovery will lag any ceasefire by a significant margin.
For energy-importing developing economies, the mid-April deadline carries direct and immediate consequences. Ghana, which holds approximately 500,000 metric tonnes of petroleum products in offshore stocks at Lomé and additional vessels anchored near Tema, has built one of the more substantial buffer positions in West Africa but the National Petroleum Authority (NPA) has already raised domestic price floors twice since the conflict began, and analysts have warned that a second leg of crude price increases would test even that buffer.
The next two to three weeks will determine whether the emergency architecture constructed since February 28 holds long enough for diplomacy to work or whether the market moves to price a prolonged disruption for the first time.
