The International Energy Agency (IEA) has announced the largest coordinated release of strategic petroleum reserves in history, but markets quickly realized that what truly determines oil prices is not the total volume available, but the daily rate of release.
According to reports, the IEA confirmed on the 11th that its 32 member states have agreed to release a total of 400 million barrels from their strategic reserves. While this figure represents the largest collective action of its kind by the IEA, surpassing the approximately 183 million barrels released in two separate actions following the 2022 Russia-Ukraine conflict, key details remain undisclosed. These include the pace of the release, its duration, and the ratio of crude oil to refined products—details often more critical than the total volume itself.
Market reaction reflected this uncertainty. Oil prices briefly dipped to around $83 per barrel after the announcement but soon rebounded, with WTI crude climbing back above $90.
The core issue lies not in inventory levels, but in supply "flow." Commodity markets are priced based on the daily physical supply and demand that is actually traded, not on static stockpile numbers. The current price surge is driven by the near-total halt of traffic through the Strait of Hormuz, a chokepoint for about 20% of global oil shipments. With the escalation of conflict, significant volumes of crude from the Persian Gulf cannot be transported normally.
Data from Citigroup and JPMorgan indicate that the blockade is causing a daily loss of 11 to 16 million barrels of crude supply to the global market. Essentially, the market has suddenly lost a supply source nearly equivalent to Saudi Arabia's output.
Therefore, the problem is not a lack of oil globally. IEA member states hold over 1.2 billion barrels in public strategic reserves, with an additional approximately 600 million barrels of corporate inventories under government oversight. Absolute inventory levels are not scarce. The real challenge is that oil cannot flow from production sites to the market.
As one commodity analyst succinctly put it: "This is a flow problem, not a stock problem." Releasing reserves can add to available inventory but cannot replace the daily global oil trade conducted via maritime routes. Simply put, unless the 400 million barrels from IEA members can be converted into daily market flows quickly enough, they cannot fill the massive gap of 16 million barrels per day.
Consequently, the market's primary concern has shifted to the speed of release. Homayoun Falakshahi, a senior analyst at Kpler, emphasized that "the devil is in the details," with the key variable being the release rate. The IEA has not announced a unified schedule, stating instead that each member will set its own timeline.
Industry estimates suggest the actual daily release rate might only range between 1.2 million and 4 million barrels. Natasha Kaneva, Head of Commodities Strategy at JPMorgan, offered a more pessimistic forecast, estimating that the coordinated G7 release might reach a maximum of only 1.2 million barrels per day. At that pace, releasing the entire 400 million barrels would take nearly a year.
The United States is expected to contribute the largest share. U.S. Energy Secretary Chris Wright stated that the U.S. would release 172 million barrels from its Strategic Petroleum Reserve (SPR) over approximately 120 days, aiming to "buy time for the global market during the supply disruption caused by Iran." However, the SPR itself faces practical limitations. Current U.S. strategic reserves stand at about 415 million barrels, only about 60% of maximum capacity, following a 180 million barrel release after the 2022 conflict.
Theoretically, the maximum drawdown rate from the U.S. SPR is about 4.4 million barrels per day, but a 2016 Department of Energy assessment indicated a sustainable rate of only 1.4 to 2.1 million barrels per day. The actual release rate in 2022 did not exceed 1.1 million barrels per day.
Compounding the issue is a significant time lag. From policy implementation to physical market arrival, a cumbersome commercial process is required. After a presidential order, the DOE needs roughly 13 days to complete bidding, awarding contracts, and beginning deliveries. Subsequently, crude must be transported via pipeline or tanker to refineries and end consumers. This means that even if releases started immediately, SPR oil would not become effective supply until late March. Meanwhile, the daily supply shortfall of 16 million barrels would continue to accumulate. JPMorgan estimates that by the end of March, the cumulative supply deficit from the geopolitical conflict could exceed 100 million barrels. A daily replenishment of a mere 1.2 million barrels would be a drop in the bucket.
More critically, the blockade's effects are cascading upstream. With oil unable to be shipped, storage tanks in producing nations along the Persian Gulf are filling rapidly. Once storage reaches capacity, producers may be forced to shut in wells. Recent data reveals that major producers like Saudi Arabia, the UAE, Iraq, and Kuwait have already begun significant production cuts, totaling up to 6.7 million barrels per day, or about 6% of global output. This number will continue to rise for each additional day the Strait remains blocked, transforming a logistics issue into a permanent loss of production capacity.
From an investor perspective, the IEA's action is seen more as a policy signal aimed at stability. It demonstrates major consumers' commitment to jointly intervene to curb energy prices and attempts to reduce risk premiums. It also aims to buy time for the restoration of shipping through the Strait of Hormuz. However, if the blockade persists, reserve releases are unlikely to genuinely close the supply-demand gap.
As one energy trader noted, "Strategic reserves can cushion the shock, but they cannot replace normal global oil trade." Thus, the true significance of this record release plan for the market ultimately hinges on one question: When will navigation through the Strait of Hormuz resume?
