Stefanie Johnston, partner & head of marine and Jarrod Parker partner & head of aviation, at law firm HF examine the challenges the marine and aviation sectors will face in 2026.

As climate pressures, cyber vulnerabilities and geopolitical instability converge, insurers in the marine and aviation sectors are navigating unprecedented turbulence and searching for new ways to adapt.

The oceans and skies are becoming more hazardous than at any point in recent decades and the industries that insure them are confronting volatility on multiple fronts. Once treated as separate disciplines, marine and aviation underwriting are increasingly handled by integrated teams, particularly in the London Market, reflecting how closely these risks now overlap.

Global commerce depends on both sectors working in harmony. A storm‑damaged port can delay aviation fuel supplies; a grounded aircraft engine can disrupt shipping schedules. The interdependence between air and sea is tightening, and insurers are recognising that these exposures form part of a single, interconnected ecosystem.

Climate, Conflict, and Connectivity

Climate change remains the most persistent challenge. For marine insurers, stronger storms, rising seas, and flooding threaten vessels, ports, and cargo routes. Aviation faces its own climate‑driven risks: extreme heat, turbulence, and unpredictable weather patterns that increase operational costs. Traditional actuarial models, built on decades of relatively stable data, are struggling to capture this new volatility.

Geopolitical instability adds further uncertainty. Ongoing conflicts in regions such as Ukraine and the Middle East have disrupted shipping lanes and flight paths, stranded assets and created complex war‑risk exposures. Sanctions and regulatory restrictions often apply across both industries, reinforcing why insurers increasingly manage these lines together.

Technological transformation is reshaping both sectors. Ships and aircraft are becoming more autonomous, data‑driven and reliant on connected systems. While this brings efficiency, it also heightens vulnerability. A single cyberattack could simultaneously disrupt maritime logistics and aviation operations, erasing the traditional boundary between physical and digital loss.

Marine & Aviation Lawyers

In this complex environment, legal advisers are taking on a more proactive role. Rather than stepping in only after an incident, we are now embedded earlier in the risk process helping insurers anticipate liability, clarify coverage and draft policies that reflect new realities like cyber, climate and technology-driven exposures.

We also play a key role when incidents cross borders or overlap between transport sectors. Coordinating multi-jurisdictional claims, navigating sanctions compliance and managing regulatory investigations require deep understanding of how marine and aviation laws intersect. Legal input helps ensure insurers and reinsurers can respond quickly and consistently, even when events span multiple legal systems.

Navigating a Shared Future

The coming decade will challenge the adaptability of marine and aviation insurers more than at any time in recent memory. The convergence of climate volatility, cyber risk and geopolitical instability is dismantling long‑held assumptions about how risk behaves. Yet this convergence is also fostering innovation. Shared expertise, integrated teams and collaborative risk management are enabling insurers to build a more holistic view of global transport exposures.

By working side by side (lawyers, underwriters and brokers) the industry can ensure resilience and innovation progress together. The seas and skies will never be free of turbulence but the strength of the market lies in its ability to evolve. Success will depend on foresight, cooperation and clarity: the foundations of an insurance sector designed to withstand even the most unpredictable conditions.
