Escalating US actions against Iran carry significant risks for global crude oil supply, potentially sending prices to multi-year highs. Iran, despite sanctions, remains a key oil producer with substantial reserves, extracting crude at remarkably low costs compared to Western nations.

The primary threat lies with the Strait of Hormuz, a critical chokepoint for global oil shipments. Approximately 20% of global liquid oil consumption transits this waterway daily. Any disruption, even a doubt about security, could trigger sharp increases in shipping insurance premiums and divert vessels.

Iran's oil exports, largely destined for China, are vital for its economy. The country's relatively low production costs mean it disproportionately benefits from high global prices.

Neighbouring countries and the wider global economy also face risks. Potential Iranian retaliatory strikes could target vital infrastructure, while soaring oil prices risk reigniting inflation and impacting political agendas.
