So, you've got a massive oil supply shock. The natural first thought for governments is: break open the emergency stash. But what if the stash is just too small for the problem? That's the sobering math coming out of JPMorgan (JPM) regarding the ongoing tensions and potential blockade in the Strait of Hormuz.
The idea is simple enough. If Iran-related conflicts choke off oil flowing through the Strait, the G7 nations could coordinate a release from their Strategic Petroleum Reserves (SPR). According to JPMorgan estimates shared by The Kobeissi Letter, that move would yield about 1.2 million barrels per day. For context, that's roughly in line with past emergency releases, which have topped out around 1.4 million barrels daily.
Here's where the math gets uncomfortable. Right now, JPMorgan notes, about 16 million barrels per day of oil are effectively "trapped" in the Gulf, unable to reach the global market if the Strait is blocked. Do the division: 1.2 divided by 16 equals 0.075, or 7.5%. A coordinated global release from strategic stockpiles would therefore address less than one-tenth of the potential daily supply shortfall. It's like using a garden hose to put out a house fire—helpful in a very localized way, but not nearly enough to solve the core problem.
"While emergency reserves can provide temporary relief, they are not a substitute for lost supply or a solution to flow constraints," the report concludes. It's a crucial distinction. Reserves can buy time, but they can't unblock a critical maritime chokepoint or replace the steady flow from major producers.
Complicating matters, the biggest player in the SPR game isn't operating at peak capacity. The same JPMorgan note points out that the United States' own reserve is facing headwinds. Thanks to ongoing site modernization and simply having lower inventories on hand, its operational capacity is expected to be less than the one-million-barrels-per-day rate it managed back in 2022. So, the primary source for any major release might be starting from a weaker position.
The scale of this potential crisis is what has other Wall Street giants sounding the alarm. Analysts at Goldman Sachs (GS) have warned that this situation, driven by the U.S.-Iran conflict, constitutes the largest oil supply shock on record. They argue that even a "massive" drawdown of 400 million barrels from the International Energy Agency's collective reserves might not be enough to counteract a loss of 10 million barrels per day of supply.
To understand how big that is, Goldman notes this disruption has already slashed Persian Gulf exports to about 3% of their normal levels. That impact, they say, surpasses previous epoch-defining oil crises like the 1973 OPEC embargo and the supply shocks during the 1990 Gulf War. In other words, we're in uncharted territory.
The takeaway for markets and policymakers is stark. Strategic petroleum reserves are a vital tool, but they have limits. When a crisis stems from the physical closure of a geographic bottleneck like the Strait of Hormuz—through which a huge portion of the world's seaborne oil trade passes—the solution can't just come from a tank farm in Texas or a salt cavern in Louisiana. The numbers from JPMorgan and Goldman Sachs make it clear: this is a problem of a different magnitude, and the usual emergency playbook might only cover the first page.
