Markets took five weeks to price the Iran war and five months to unprice it

Start with the barrel, because it is the part that did not round-trip. Brent closed near $72 before the war and reached almost $120, a move of about 67 per cent, and it now sits roughly 20 per cent above that prewar close, which puts it near $86 and means something like 70 per cent of the spike has been handed back ^{[6][21][22][23]}. Anyone who bought the late-March low has almost 22 per cent on the S&P and 27 per cent on the Nasdaq ^[3]. So the equity discount was priced in five weeks and unpriced over roughly five months ^[2][3][26], and the cash cost was neither: the International Air Transport Association expects jet fuel to average 70 per cent more than in 2025 ^[8], and carriers have answered with surcharges, baggage fees, thinner schedules and, notably, plans for new routes that were quietly dropped ^[10].

That last item is the resource-allocation tell. Lufthansa Group took out 20,000 short-haul flights and Spirit Airlines, troubled long before this, evaporated ^[9], and Columbia economist Brett House's read is that with less choice and less competition there is very little pressure to bring fares back down over the next few months ^[11]. Capacity is the durable casualty; the index drawdown was the temporary one.

Geopolitical shocks may simply decay faster than the models built to price them. The IMF said in July that the economy was being shaped by two major forces pushing in opposite directions, with enthusiasm over artificial intelligence offsetting the war's drag on growth ^[5], which makes the round trip a net of two positions rather than evidence that war does not bite. Or rather, the more interesting version of the thesis: geopolitical discounts decay quickly when a capex boom is bidding on the other side of them, and nobody has yet observed the decay rate without that bid. Cerity Partners' Michael Ashley Schulman called it the financial equivalent of a Mission Impossible scene ^[12], which is closer to the mechanism than "resilience" is.

The reallocation the oil price forced is real money. Global EV share is projected at 29 per cent of vehicle sales in 2026 against 25 per cent last year, four points, a 16 per cent relative gain, achieved while demand fell in both the United States and China ^[13][24], with Singapore up 110 per cent, New Zealand 180 per cent and Colombia 300 per cent year over year ^[14]. Sphera's Scott Lehmann counts 26 countries and regions announcing clean energy and electrification measures in response to the war, and says the crisis is forcing investment faster than any policy framework would have ^[15]. That capital is being committed against a premium that may not survive a settlement.

Which is where the pricing gets awkward. Crypto Briefing reports prediction-market odds of about 11 per cent, call it one chance in nine, that Iran reconstruction funding is included in a US-Iran deal ^[17][25], with Trump and Iranian foreign minister Javad Zarif the principals and Qatar and Pakistan mediating ^[18]. Equities are trading as though the war is behind them while the settlement that would actually clear the fuel bill is priced as a long shot.

The thesis fails cleanly in two directions. If Brent gives back the remaining $14 and surcharges start rolling off inside two quarters, the durable-cost half of this is wrong and the shock really was shallow and short. If the AI leg wobbles and the indexes retest March while Brent holds near $86, the recovery rested on borrowed conviction rather than fundamentals, and the war discount stayed priced in the whole time.
