Global oil markets have been affected by the US Israel war with Iran, leading to higher jet fuel prices and increased attention on supply risks.

But how serious is the situation? While some experts point to tightening supply chains and regional bottlenecks, others say there is no clear evidence so far of immediate shortages.

Even so, the refining and distribution of jet fuel remains a potential vulnerability, as disruption can have notable impacts even when crude oil itself is available. With air travel crucial to trade and tourism, the resilience of fuel supply is a growing concern for economies and travellers. Can alternative suppliers and fuel sources help limit the impact of future disruption?
