The deployment of HMS Anson to the Arabian Sea and the ongoing blockade of the Strait of Hormuz by Iran significantly increase geopolitical risk, potentially leading to higher oil prices and increased volatility in global energy markets. This escalation could also boost demand for defense stocks as nations enhance military readiness.
The United Kingdom has deployed its nuclear-powered submarine, HMS Anson, armed with Tomahawk missile and Spearfish torpedo, to the Arabian Sea. This move, reported by Daily Mail and unconfirmed by India — Ministry of Finance (India), positions the United Kingdom for potential long-range strikes if regional tensions escalate. The deployment follows the United Kingdom's authorization for the United States to use British bases for strikes on Iranian targets threatening the Strait of Hormuz. Iran's ongoing blockade of the Strait of Hormuz, a critical global energy route, has been condemned by the United Kingdom and 21 other nations, further exacerbating tensions. Prime Minister of the United Kingdom, Keir Starmer, would authorize any missile launch from HMS Anson, which previously arrived in Australia as part of the AUKUS security partnership.
