For some background on why we're not going to see prices come back down to Feb 2026 levels I can recommend a very recent interview with Professor Jefferey Sachs. 

In essence Sachs sees America's problems primarily as self-inflicted consequences of an overextended foreign policy, excessive military spending, political capture, and unsustainable debt. He argues that Trump's policies are not reversing American decline but accelerating it.

Therefore the Iranians will retain control of the SoH and remain an important player in world energy markets and there is nothing the US can do to stop this.

So back to the topic of this thread "Fuel prices and security of supply"? Fuel prices will remain elevated to prices prior to March 2026, and supply will remain fragile. The difference is being made up by withdrawals from reserves currently, which will need to be replaced putting upward pressure on price.
