Kharg Island wasn’t destroyed, and yet, oil surged, shipping stopped, and global markets reacted as if it had been.
This is what happens when war targets systems, not territory.
Great piece. The GCC workarounds have the same limitations as the Iranian one, they can’t handle the load. I would also flag that some of the restraint around attacking energy infrastructure on Kharg has to do with the fact that Iran would then effectively destroy GCC infrastructure, taking way more than 1.5 million barrels offline for much longer. In addition, forces in Yemen are on standby to close off the Red Sea access point if it becomes necessary.
Thank you, that’s a genuinely valuable addition and adds an important layer to the escalation logic. The symmetry matters here. Once energy infrastructure becomes fair game at scale, the exposure isn’t linear and it widens across the Gulf very quickly, especially if multiple routes are stressed simultaneously.
The Yemen angle reinforces that this isn’t just about Hormuz in isolation. If Red Sea access becomes contested at the same time, the system starts to lose its ability to reroute, which is really what keeps it functioning under stress. What this suggests is that restraint isn’t just about avoiding immediate price spikes, it’s about avoiding a scenario where too many nodes are stressed at once and substitution breaks down entirely.
The open question is how stable that restraint is if pressure continues to build. At what point does the logic shift from mutual vulnerability acting as a constraint to it becoming a justification for escalation?
One thing to watch: whether disruptions begin to synchronise across Hormuz and Red Sea routes, that’s the point where redundancy stops working and the system starts to lock up rather than adapt.
The functionality shock framing is the right distinction and it's underused.
What you describe at Kharg extends further: Iran has now demonstrated it can monetise the functionality gap rather than just exploit it. Charging $2mn per transit converts a disruption into a revenue model.
The strait doesn't need to reopen for Iran to benefit, it just needs to remain selectively functional. That changes the incentive structure permanently.
Thank you! That’s a sharp extension and it gets at something the piece only hints at but doesn’t fully develop. Framing this as monetising the functionality gap really changes the picture. Disruption stops being purely a cost-imposition tool and starts functioning as a lever, not just denying flow, but pricing conditional access to it.
The point about selective functionality too is especially interesting. A fully closed strait forces a coordinated response. A selectively permeable one, where passage exists, but only under certain terms — sits in a much more ambiguous space. It’s harder to escalate against, but it still reshapes behaviour across the system.
The open question is how far that model scales. Does this remain tied to geography like Hormuz, where control is physically enforceable? Or does this logic begin to appear in other systems — shipping insurance, chokepoint infrastructure, financial rails — where access can be modulated rather than outright blocked?
It feels like a shift from targeting bottlenecks to actively operating them under stress, which is a different kind of power altogether. It would be interesting to watch whether pricing power formalises — if conditional access starts showing up consistently in freight rates, insurance structures, or routing premiums, that’s when selective functionality will shift from tactic to system logic.
The insurance withdrawal mechanism you describe suggests the logic is already migrating. War-risk exclusions, P&I club decisions, flag-state bilateral deals — these are all forms of conditional access operated at a distance from the physical chokepoint.
Hormuz is where it became visible. The financial infrastructure is where it spreads.
