Consumers face potential increases in energy prices and inflation due to disrupted oil supplies through the critical Strait of Hormuz, which handles ~21% of global petroleum transit. Supply chain delays and higher shipping costs will increase prices for imported goods.
Potential for increased international diplomatic intervention, possible OPEC coordination to stabilize oil markets, strengthened U.S. sanctions enforcement, and potential UN Security Council discussions. Allied nations may seek alternative energy sources and shipping routes.
