Could Russia Follow the “Hormuz Playbook” In the Baltic and Black Seas?

Key Takeaways

• Iran shut Hormuz by insurance repricing, not mines
• Russia can threaten Danish and Turkish Straits with cheap drones
• A single $10k drone could halt $40‑80 million LNG cargoes
• NATO lacks mechanisms to counter insurance‑driven maritime closures
• Proposed fixes: monitoring cell, sovereign reinsurance, counter‑drone posture

Pulse Analysis

The "Hormuz model" reshapes how maritime security is assessed. In early 2024, a handful of drone attacks prompted Lloyd’s Joint War Committee to reclassify the Strait of Hormuz as high‑risk, causing insurers to withdraw coverage within 48 hours. Shipping firms, faced with unaffordable premiums, halted transits, effectively closing a chokepoint that handles a third of global oil. This insurance‑driven closure proved cheaper and faster than traditional blockades, highlighting a new lever of geopolitical coercion that operates below the threshold for collective defence responses.

Europe’s exposure is now evident in the Baltic and Black Sea corridors. Russia’s Geran‑2 and Gerbera drones, produced at a rate of roughly 3,000 units per month, can reach the Danish Straits from Kaliningrad and Belarus, while shadow‑fleet vessels provide sea‑launch options. Recent incursions into NATO airspace and the temporary shutdown of Danish airports illustrate a growing willingness to test the insurance market’s tolerance. A single successful strike on an LNG carrier could trigger Lloyd’s to label the Danish Straits high‑risk, prompting insurers to hike premiums or cancel policies, thereby choking off $40‑80 million cargoes with a $10,000 investment.

Policymakers must adapt to this hybrid threat. Establishing a permanent war‑risk monitoring cell that liaises directly with Lloyd’s and P&I clubs would give governments early warning of repricing cascades. Sovereign reinsurance facilities could backstop strategic LNG and grain shipments when commercial cover evaporates, preserving supply continuity. Finally, scaling NATO’s patrols into dedicated counter‑drone and mine‑countermeasure postures would raise the cost of a credible threat, deterring insurers from withdrawing coverage. Together, these steps aim to neutralise a weapon that attacks markets rather than ships, safeguarding Europe’s energy and food security.
