US officials weighing a short strike campaign against Iran keep the escalation tail live for crude. Polymarket prices only 2% for a final nuclear deal by October 31 and 18% for normal Hormuz traffic by December 31, so the market also doubts a de-escalation that would remove the premium.
Delta cut its forecast over fuel costs as Isaias took 1.46 million barrels a day of Gulf output offline. A storm outage on top of an existing war premium shows elevated energy costs passing through to corporate earnings.
Brent rose 4.1% and stayed above $100 while the US blockade at the Strait of Hormuz remained in force. Vitol's chief executive credited ship-to-ship transfers in the Gulf of Oman with keeping prices from going much higher, so the war premium is being held down by workarounds, not removed. Polymarket prices Hormuz traffic returning to normal by December 31 at 18% ($526K book), which agrees that the premium will last.
ECB minutes show the September rate hike was driven by an energy shock that policymakers now expect to keep headline inflation well above target into the first half of 2027. The war premium is feeding through into developed-market inflation and policy for a long time, not just briefly.
$104 crude set off a 1,045-point Sensex fall and a 10% jump in the India VIX volatility index. The war premium is moving income away from big importers and into their asset prices, as the thesis expects.
