The escalating Iran war is triggering a new energy crisis that threatens to strain public finances across Europe and Asia. Governments are facing a difficult choice: spend heavily to shield citizens from soaring fuel costs or risk political backlash by maintaining fiscal discipline. £53 million in Britain is earmarked to help heating oil users, while Portugal has cut diesel taxes and Greece capped fuel margins. South Korea expands energy vouchers. 20 percent of global oil and LNG through the Strait of Hormuz faces disruption, with Asian markets particularly vulnerable. 397 billion euros in EU energy subsidies doubled in 2022, and Britain's debt interest now consumes £1 in every £10. 0.5 percent growth in Germany could halve if prices persist.

Thailand's fuel fund faces deficits again, risking sovereign downgrades. This crisis arrives as governments rebuild budgets after pandemic spending, making the choice between economic relief and fiscal stability starker than ever.
