Shipping Shifts to Permanent Crisis Mode as Drones, Mines and Jamming Spread

Key facts

• BIMCO issued late-May guidance for Strait of Hormuz transits covering missile/drone attacks, signal jamming, mines and boarding attempts.
• Shipping executives and insurers at Posidonia described a shift to a quasi-wartime footing as overlapping crises become structural.
• EU Transport Commissioner warned against normalising chokepoint restrictions that could set coercive precedents in international waters.

The global shipping industry is re-baselining its risk assumptions around the idea that major-power rivalry, regional conflict spillover and coercion at sea will recur rather than recede. Executives speaking at the Posidonia shipping conference in Athens framed today’s environment as qualitatively different: layered crises emerging rapidly, with the wider regulatory and sanctions framework increasingly contested. The operational consequence is a shift from protocol-driven, calculable risk toward avoidance decisions, flexible fleet deployment and faster corporate decision cycles.

A concrete indicator is BIMCO’s late-May guidance for transits through the Strait of Hormuz. The document advises merchant crews on responses to missile and drone attacks, satellite signal jamming, mine threats and boarding attempts, supported by checklists and risk tables. This is not merely tactical seamanship; it reflects commercial shipping adopting threat taxonomies associated with modern conflict, including the normalisation of electronic warfare effects (jamming/spoofing) and unmanned strike risks against civilian tonnage.

Industry leaders also highlighted Russia’s “shadow fleet” as a longer-duration destabiliser, eroding compliance norms and oversight in the tanker market while complicating sanctions enforcement and safety standards. Combined with Red Sea attacks and Gulf tensions, insurers and operators described oceans as an arena of major-power contest “from the Arctic to the South China Sea,” implying broader premium inflation, route diversification and potential capacity constraints as ships divert or stand off high-risk chokepoints.

For Europe, the strategic exposure is twofold. First, any sustained disruption at Hormuz or the Red Sea directly affects European energy flows, industrial inputs and inflation-sensitive supply chains, while increasing pressure on European navies and partners to sustain credible freedom-of-navigation and maritime security postures. Second, European policymakers face a governance challenge: if coercive practices, de facto tolling, or episodic closures become accepted as routine, the precedent risks weakening the rules-based framework underpinning European trade. European Transport Commissioner Apostolos Tzitzikostas explicitly cautioned against treating Hormuz disruptions as a “new normal,” arguing that retreat would set dangerous precedents and undermine navigation principles built over decades.
