Oil's Physical Shock vs. Financial Reality: A Balance Sheet Analysis **Strait of Hormuz Closure Creating Short-Term Oil Squeeze, But J.P. Morgan Sees $60-Brent Comeback**

The war in the Middle East has triggered the largest supply disruption in the history of the global oil market. The effective closure of the Strait of Hormuz, a vital artery for over 20% of global oil transit, has forced Gulf producers to slash output by at least 10 mb/d. This unprecedented curtailment is projected to cause global oil supply to plunge by 8 mb/d in March, a shock that is only beginning to be absorbed.

The physical impact is stark. With crude and product flows through the strait collapsing from around 20 mb/d to a trickle, producers are forced to shut in production. This has already led to more than 3 mb/d of refining capacity in the region shutting due to attacks and a lack of viable export outlets. The vulnerability is most acute for diesel and jet fuel markets, which rely heavily on Gulf exports and have limited flexibility to ramp up output elsewhere. The IEA notes that runs elsewhere will be increasingly limited due to feedstock availability, creating a tight supply chain for these critical products.

Financial markets have reacted violently to this physical shock. The Brent crude oil price has surged to a four-year high of almost $120 a barrel, a climb of over 50% from the start of the year. This price spike reflects the immediate scarcity, but it also introduces new risks. The conflict is expected to curb global oil demand by around 1 mb/d during March and April due to widespread flight cancellations and disrupted LPG supplies, adding a layer of economic uncertainty on top of the supply crunch.

The bottom line is a market under severe strain. The sheer scale of the production cut-10 mb/d from the Gulf alone-creates a massive hole in the supply ledger. While non-OPEC+ producers like Russia and Kazakhstan are stepping in, their ability to fully offset the loss is constrained. This physical shock is the foundational pressure behind the price surge, and its resolution will hinge entirely on the return of shipping flows through the Strait of Hormuz.

Underlying Fundamentals: A Market of Surplus

The physical shock is severe, but it is not yet enough to overcome the market's underlying fundamentals. Even with the war-induced disruption, the broader supply-demand balance points toward a surplus, not a deficit. J.P. Morgan Global Research sees this clearly, forecasting that Brent crude will average around $60 a barrel in 2026. Their bearish view is rooted in the expectation that global supply will outpace demand, a condition that has already been visible in recent data.

The numbers support this outlook. While global oil demand is projected to expand by 0.9 million barrels per day in 2026, the increase in supply is set to be even stronger. Non-OPEC+ producers, including U.S. shale, are expected to provide a significant buffer, accounting for the entire projected growth in global output. This dynamic means that even after the Gulf's 10 mb/d curtailment, the market is likely to see a sizable surplus later in the year. The IEA notes that global oil supply is set to rise by 1.1 mb/d on average in 2026, with non-OPEC+ producers driving the entire increase.

This creates a critical vulnerability for specific products. The diesel and jet fuel markets are the most exposed because they rely heavily on Gulf exports and have limited flexibility to ramp up output elsewhere. The region's refining capacity has already been hit hard, with more than 3 mb/d of refining capacity shutting due to attacks and a lack of export outlets. Runs in other regions will be increasingly limited by feedstock availability, tightening the supply chain for these critical products. The physical shock is hitting the most rigid parts of the system first.

The bottom line is a market caught between two forces. The immediate scarcity is driving prices to four-year highs, but the structural trend of strong supply growth is pushing the market toward a surplus. For the price rally to be sustained, the supply disruption would need to be prolonged and severe enough to permanently alter production patterns. For now, the fundamentals suggest that any geopolitical rally will eventually subside, leaving the market to grapple with the underlying oversupply.

Financial Signals and Market Mechanics

The price spike is a direct financial signal of the market's fear. The Brent crude oil spot price jumped from an average of $71 per barrel on February 27 to $94/b on March 9 following the onset of military action. This surge, driven by high uncertainty about the conflict's duration and its effect on flows through the Strait of Hormuz, has added a large risk premium to oil prices. The primary risk that would cause prices to continue rising is an extended closure of this major world oil transit chokepoint.

This sensitivity is most visible in the gasoline market. Crude oil and gasoline prices rallied sharply in early March, with April RBOB gasoline posting a 1-week high. The market's reaction underscores how disruptions to Middle Eastern supplies-where a significant portion of the world's crude originates-quickly transmit to refined products at the pump. The rally was further supported by a jump in the crude crack spread, which encouraged refiners to purchase crude to make more gasoline.

Financial mechanics also point to a potential backstop. The U.S. Strategic Petroleum Reserve (SPR) is designed to provide temporary relief during supply shocks, assisting consumers and keeping critical parts of the economy running. While it is not a long-term answer, its existence can go a long way toward softening crippling price hikes during emergencies.

The bottom line is a market pricing in extreme uncertainty. The recent price moves reflect a scramble to assess actual disruptions to oil flows, with the risk premium currently outweighing underlying fundamentals. For the rally to be sustained, the supply disruption would need to persist long enough to fill storage behind the chokepoint and force more production shut-ins. If flows resume, the model suggests global oil production will continue to outpace consumption, leading to rising inventories and eventually weighing on prices later in the year.

Catalysts and Risks: The Path to Resolution

The market's trajectory hinges on a single, unfolding variable: the duration of the conflict and the resumption of shipping flows through the Strait of Hormuz. This chokepoint is the central catalyst. The primary risk that would cause prices to continue rising is an extended closure of the Strait of Hormuz, which is a major world oil transit chokepoint. If this reduction in vessel volume persists, oil storage behind the chokepoint will quickly fill, causing oil producers to shut in even more production, lending further support to oil prices.

The next major test arrives this Sunday with the OPEC+ meeting. While the group is expected to agree to a modest increase in production quotas for May, the move is widely seen as symbolic. The real signal will be the size and timing of the increase. As one source noted, the group needs to "react, at least on paper," to position itself to add more barrels should the strait reopen. A larger-than-expected increase could signal confidence in a near-term resolution, potentially capping the rally. A smaller or delayed hike might be read as a sign of lingering uncertainty, supporting higher prices.

Watch for two other key data points to gauge the disruption's material impact. First, monitor inventory draws in OECD countries. A sustained draw would indicate the physical shock is tightening the global balance more than the market's current model assumes. Second, look for signs of demand destruction. The conflict is already expected to curb global oil demand by around 1 mb/d during March and April due to widespread flight cancellations and disrupted LPG supplies. If this demand loss persists or deepens, it would provide a powerful offset to the supply shock, accelerating a price correction.

The bottom line is a market waiting for a resolution. The physical disruption is severe, but the underlying supply-demand balance points toward a surplus later in the year. The path forward depends on whether the conflict's duration is long enough to fill storage behind the chokepoint and force a prolonged production cut. If flows resume, the model suggests global oil production will continue to outpace consumption, leading to rising inventories and eventually weighing on prices. The next few weeks will reveal which force-geopolitical shock or structural surplus-wins.
