One of the patterns I keep watching in this Hormuz saga is how quickly physical logistics adapt to constraints that markets initially treat as catastrophic. Those of us working in energy have learned that the system almost always finds a way. Ships get bigger, routes get longer, storage gets drawn down, and the barrels keep flowing.
The past month seemed to prove that lesson once again.
Tanker-tracking data showed oil moving west of Hormuz had largely returned to pre-conflict levels. Saudi Arabia had pushed roughly 34 million barrels through the Strait since the June reopening agreement. UAE exports had recovered as well, supported by the Fujairah bypass system and a fleet of less-than-transparent tankers willing to operate where others would not. The recovery was real.
Then Tuesday happened.
Following attacks on commercial vessels near the Strait, a U.S. military response, and the collapse of what had been described as a ceasefire, crude prices jumped more than 6 percent and erased much of their return to pre-conflict levels. The market was reminded of something it occasionally forgets: adaptation reduces risk, but it does not eliminate it.
Fewer Ships, Bigger Ships
To me one of the most interesting parts of the recovery was not the volume itself. It was how that volume moved.
Transit counts through the Strait remained well below historical norms. Before the conflict, roughly 25 to 30 ships passed in each direction every day. Yet export volumes recovered far more quickly than vessel counts. The difference came from a shift toward VLCCs, the two-million-barrel supertankers that can move enormous volumes with fewer voyages.
This is exactly what an engineer would expect from a constrained system. If each transit carries additional risk, the logical response is to reduce the number of transits and maximize the payload of each one. Fewer voyages. Larger parcels. It is the same principle that drives pipeline batch optimization or truck routing at a fuel distributor, just scaled up to the most strategically important waterway on Earth.
The efficiency is impressive, BUT, it also concentrates risk. When a single vessel carries two million barrels of crude, one missile can create a much larger disruption, a much larger insurance claim, and a much larger headline.
The Ceasefire That Wasn’t
The immediate market reaction to Tuesday’s incidents was revealing.
By Wednesday, tanker crossings reportedly fell to just 13 vessels, compared with an average of roughly 33 per day during the preceding week. Shipowners do not wait for official declarations. They watch the same AIS screens as everyone else and reprice risk in real time.
The temptation after June’s recovery is to assume the system will simply adapt again. Maybe it will. But adaptation is not free. Longer voyages increase shipping costs. War-risk premiums raise insurance expenses. Greater reliance on dark-fleet activity reduces transparency. Every workaround consumes some of the buffers that make the global energy system resilient in the first place.
Roughly one-fifth of global petroleum liquids still moves through this single chokepoint. You can reroute around it at the margin. You cannot replace it.
Diesel Is Where the Pain Lives
Crude oil captures the headlines. Diesel is where the economic consequences show up.
The NYMEX 3-2-1 crack spread, a widely watched measure of refining profitability, surged to a record $64.58 per barrel on July 8. At the same time, European diesel margins moved above $60 per barrel after Russia restricted diesel exports in response to Ukrainian drone attacks that have damaged significant refining capacity. Those developments matter because distillate inventories were already tight.
The EIA expects U.S. distillate inventories to finish the year at multiyear lows due to refinery closures, strong export demand, and sustained inventory draws. Diesel remains the bloodstream of the physical economy. It moves freight, powers agricultural equipment, supports industrial activity, and heats a significant portion of the Northeastern United States.
When distillate inventories are thin, disruptions travel quickly. A geopolitical event thousands of miles away can show up in transportation costs and fuel prices much faster than most consumers expect. For fleet operators, farmers, and energy-intensive businesses, that reality deserves more attention than the daily movement of crude futures.
What the Strongest Quarter in Years Really Means
Against this backdrop, Wall Street expects the energy sector to report one of its strongest quarters in years. FactSet estimates suggest energy will deliver the highest year-over-year earnings growth of any S&P 500 sector, with refining and marketing profits rising more than 200 percent.
That should not necessarily be interpreted as a sign of strength. Record refining profits often signal the opposite. They are evidence that the system is operating with limited spare capacity, constrained inventories, and elevated geopolitical risk. Exceptional margins are frequently the market’s way of rationing scarcity.
The oil market adapted remarkably well in June. It will probably adapt again. But every adaptation draws down a little more of the slack that makes the next disruption manageable. That is the lesson I keep coming back to.
Resilience is not an inexhaustible feature of the energy system. It is kind of like inventory.
And inventories, unlike narratives, can eventually run out.
