Global Oil Reserves May Plummet if Strait of Hormuz Stays Blocked

• Inventories expected to reach near-record lows of 7.6 billion barrels by end of May, with only about 800 million barrels actually available without straining the system (the rest needed to maintain minimum pipeline and tank levels)
• JPMorgan forecasts critically low inventory levels of 6.8 billion barrels by September if Hormuz remains closed, while Rapidan Energy predicts product inventories will hit critical levels sooner in July or August
• Analysts expect oil prices will spike before third quarter 2026 to reduce demand and prevent a complete supply chain failure, likely causing 'a severe economic contraction' rather than allowing inventories to reach critically low levels

Summary: Global Oil Reserves at Risk from Strait of Hormuz Closure

Key Crisis Development:

The ongoing closure of the Strait of Hormuz is draining global oil inventories at a record pace, threatening critical supply chain disruptions and severe price spikes. The International Energy Agency warns that "rapidly shrinking buffers" may trigger future price surges, particularly ahead of peak summer demand.

Critical Data Points:

• Global oil stockpiles fell from 8 billion barrels (end of February) to 7.8 billion barrels (end of April), according to UBS
• Inventories projected to hit near-record lows of 7.6 billion barrels by end of May
• JPMorgan forecasts critically low levels of 6.8 billion barrels by September if closure continues
• Only 800 million barrels are truly available without straining the system; the remainder is needed for operational circulation in pipelines and tanks

Companies and Analysts:

Exxon Mobil CEO Darren Woods confirmed inventories initially cushioned the March-April disruption but warned prices will rise as stocks deplete. Analysis from UBS, JPMorgan (led by Natasha Kaneva), and Rapidan Energy provides convergent forecasts on the timeline to crisis levels.

Market Implications:

Analysts predict oil and product prices will spike significantly before inventories reach critically low levels, likely before Q3 2026 according to Rapidan Energy. JPMorgan notes product inventories could hit critical thresholds sooner (July-August). Price increases will curtail demand but trigger "severe economic contraction."

Rapidan warns the global economy could "seize up" with transportation infrastructure unable to source fuel at any price without intervention through demand-destroying price spikes.
