What if this isn’t a shock?
Markets see a shock. The bigger risk is the whole system has changed.
The war against Iran has produced an extraordinary volume of financial analysis: barrel-per-day disruption estimates, oil price forecasts, rerouting costs, inflation pass-throughs, insurance repricing. Much of it is sophisticated and useful. But almost all of it rests on the same unstated assumption: that this is a shock to be priced and eventually mean-reverted.
But what if it isn't a shock?
A shock is a disruption within a stable system. Prices spike, markets adjust, the system absorbs the blow and returns to something like its prior state. We have good models for shocks and financial risk management was built for them.
A regime shift is different. It's a change in the underlying rules – the institutional architecture, the security arrangements, the patterns of cooperation on which the system itself depends. After a regime shift, there is no prior state to return to, because the baseline has moved.
The problem is that shocks and regime shifts look identical in their early stages. In both scenarios, oil spikes, markets sell off and the news cycle is saturated. The difference only becomes apparent through a structural lens, and by the time it's obvious, the most valuable decision-making window has usually closed.
