Global crude inventories are draining at a record pace following the Strait of Hormuz disruption. JPMorgan and the IEA warn that the operational floor, below which refineries physically cannot function, could be breached by September 2026.
When Iran's conflict with Israel escalated into a full naval blockade of the Strait of Hormuz in February 2026, it did not just spike oil prices; it started a clock. A clock that, according to JPMorgan Commodities Research and the International Energy Agency (IEA), may run out of time by September.
The Strait of Hormuz is the world's most critical oil chokepoint, carrying roughly 21 million barrels per day, which is about 20% of global supply. With the Strait effectively closed, the world has been drawing down its stored reserves at an unprecedented rate. What was once a comfortable cushion of 8.4 billion barrels of visible inventory is now in freefall.
INVENTORY DRAWDOWN — THE TIMELINE
The table below tracks the trajectory of global visible oil inventories from the pre-war peak through to the projected operational floor. These figures draw on JPMorgan Commodities Research data using Kpler, IEA, EIA, OilChem, PAJ, Singapore, and JODI datasets.
THE TWO DANGER THRESHOLDS
JPMorgan's analysis identifies two critical levels. The first: 7.6 billion barrels is the 'operational stress level,' expected to be reached by June 2026. At this point, pipeline pressure drops, refinery throughput becomes erratic, and spot prices begin spiking unpredictably.
The second: 6.8 billion barrels is the 'operational floor,' the absolute physical minimum required to keep the world's refineries and pipeline networks running. This is not a financial threshold; it is an engineering one. Below it, fuel shortages stop being a price problem and become a supply problem. The IEA projects this could be breached as early as September if the conflict is not resolved.
CURRENT SCENARIOS
The market is currently pricing between the base and stress case. The resolution of the Hormuz blockade is the single most important binary event for global energy markets in the second half of 2026.
HISTORICAL CONTEXT: WORSE THAN 1973?
The 1973 Arab oil embargo cut global supply by roughly 7%. The 1990 Gulf War disruption removed about 4.3 million barrels per day temporarily. The current Hormuz closure is affecting anywhere from 8 to 15 million barrels per day, making it structurally the most severe supply shock in the post-war era.
The crucial difference from 1973 is that today's world runs on just-in-time energy delivery. Strategic reserves exist, but they were designed to buffer weeks, not months. The IEA's coordinated SPR release mechanism can inject roughly 180–200 million barrels over 90 days, which is meaningful, but insufficient if the closure extends beyond June.
WHAT THIS MEANS FOR INDIA
India imports roughly 35-50% of its crude oil needs, i.e., approximately 4.7 million barrels per day. With Hormuz disrupted, the country's three main supply corridors from the Gulf are under pressure. While India had been quietly building its Strategic Petroleum Reserve and had secured discounted Russian crude over the past two years, those buffers have limits.
POLICY RESPONSE: WHAT GOVERNMENTS ARE DOING
The IEA activated its emergency coordinated release in March 2026, which is the third such activation in history. Member nations agreed to release 1 million barrels per day from strategic reserves for 60 days. The US has been drawing down its SPR, which stood at approximately 370 million barrels entering the crisis.
India's government has kept retail fuel prices frozen since March, absorbing the subsidy burden through OMCs, a policy that is fiscally manageable in the short run but creates serious balance-sheet risk if prices remain elevated past Q2. The Ministry of Petroleum has accelerated talks with Russia, the UAE, and Angola for non-Hormuz-routed supply.
The RBI, meanwhile, flagged oil prices as the primary upside risk to inflation in its April policy statement, noting that a sustained $110+ Brent scenario would make the 4% CPI target 'significantly harder to defend' in H2 FY27.
THE BOTTOM LINE
The world has roughly 120 days between now and September to either resolve the Hormuz crisis diplomatically or engineer a demand destruction large enough (5.6 million barrels per day) to prevent the operational floor from being breached. Neither is easy.
For India, the calculus is stark: secure alternative supply routes, expand strategic reserves aggressively, and prepare contingency fuel pricing policy now before the stress level is reached in June, not after. The clock JPMorgan identified in February is still running. The market is watching whether policymakers move faster than the inventory drawdown.
