Several Gulf stock markets declined after renewed fighting between the United States and Iran increased fears of further disruption to regional energy exports. Markets in Dubai, Abu Dhabi and Qatar recorded losses, while oil prices rose as investors reacted to the possibility of reduced shipping through the Strait of Hormuz. Gulf economies have expanded into tourism, finance, property and technology, but oil and gas exports remain central to government revenue and investor confidence. A prolonged conflict could increase insurance costs, delay shipments and weaken regional growth even in countries that are not directly involved in the fighting.
