Why British security extends along global trade routes

British commitments run from the Pacific and Indian Ocean through the South Atlantic and Antarctic territories. Trade coercion in the Strait of Hormuz and disruption in the Suez Canal show why maritime order matters to Britain even when no British territory is attacked. The economy depends on goods, shipping, finance, and insurance moving through a global system whose interruptions impose real costs. The Royal Navy's task is therefore partly to deter states from manipulating that system and to reduce the duration and cost of disruptions when they occur.
