UK Foreign Secretary Yvette Cooper Calls for Full Resumption of Shipping Through Strait of Hormuz

British Foreign Secretary Yvette Cooper urged the international community to ensure the full and uninterrupted resumption of commercial shipping through the Strait of Hormuz, a critical maritime chokepoint for global energy supplies, during her remarks at the Antalya Diplomacy Forum in Turkey on April 18, 2025. Cooper emphasized that freedom of navigation in the strait is vital not only for regional stability but also for the global economy, given that approximately 20% of the world’s oil supply passes through the waterway each day.

Her call comes amid ongoing tensions in the Gulf region, including intermittent disruptions to shipping linked to regional conflicts and maritime security concerns. Cooper reiterated the UK’s commitment to working with allies, including the United States and regional partners, to uphold international maritime law and support secure passage for all vessels, regardless of flag.

Why the Strait of Hormuz Matters

The Strait of Hormuz, located between Oman and Iran, connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is one of the world’s most strategically critical waterways, serving as the primary route for oil exports from major producers such as Saudi Arabia, Iraq, the United Arab Emirates, Kuwait, and Qatar. According to the U.S. Energy Information Administration, an average of 21 million barrels of oil per day flowed through the strait in 2024, representing about a fifth of global petroleum liquids consumption.

Any disruption to shipping in the strait can have immediate ripple effects on global energy markets, influencing oil prices and affecting economies worldwide. Historically, the strait has been a focal point of geopolitical tension, particularly during periods of heightened U.S.-Iran friction or regional instability.

UK’s Position on Maritime Security

Cooper stressed that the UK remains committed to preserving freedom of navigation under the United Nations Convention on the Law of the Sea (UNCLOS), which guarantees the right of innocent passage for all ships through international straits. She noted that the Royal Navy has regularly contributed to multinational maritime security efforts in the region, including participation in the International Maritime Security Construct (IMSC), a U.S.-led initiative aimed at enhancing surveillance and deterrence in key maritime corridors.

“We will not tolerate any attempt to impede lawful shipping,” Cooper said. “The free flow of commerce is not a negotiable principle — it is the backbone of global trade and energy security.”

She also highlighted the UK’s ongoing diplomatic engagement with Gulf states and its support for de-escalation measures aimed at reducing the risk of miscalculation or accidental confrontation at sea.

Recent Context and Regional Developments

In recent months, shipping through the Strait of Hormuz has faced intermittent challenges, including drone activity, close encounters between naval vessels, and occasional seizures of commercial ships — though large-scale blockages have been avoided. In early 2025, several incidents involving Iranian-backed groups and commercial vessels prompted heightened alertness among international naval forces.

The UK has maintained a consistent presence in the region through deployments of frigates and support vessels, often operating alongside allies from NATO and Gulf Cooperation Council (GCC) states. Cooper affirmed that these efforts will continue, with a focus on deterrence, coordination, and rapid response capabilities.

International Response and Calls for Cooperation

Cooper’s appeal was echoed by several other participants at the Antalya forum, including representatives from the European Union, Japan, and South Korea — all major importers of Gulf oil. There was broad consensus that safeguarding the strait requires sustained diplomatic engagement, robust naval coordination, and clear communication channels to prevent misunderstandings.

Analysts note that whereas military deterrence plays a role, long-term stability in the maritime domain depends on broader political solutions to regional tensions. The UK government has advocated for renewed dialogue between Gulf states and Iran, particularly on confidence-building measures related to maritime conduct.

Conclusion

As global energy markets remain sensitive to supply shocks, the Strait of Hormuz continues to be a linchpin of international trade and security. Foreign Secretary Yvette Cooper’s call for the full resumption of shipping underscores the UK’s commitment to upholding maritime freedom and working with partners to ensure stable, predictable access to this vital waterway. With energy security increasingly intertwined with geopolitical stability, maintaining open and safe passage through the Strait of Hormuz remains a shared interest of nations worldwide.
