Shipping, Security and Statecraft: Maritime Resilience in a Contested World

The UK’s resilience begins at sea. Shipping carries around 95% of UK trade, keeping goods, energy and materials moving – most often quietly and without much public attention. That invisibility should not, however, lead us to underestimate its importance. In a more contested and uncertain world, shipping is no longer simply a commercial service operating in the background. It is a strategic industry, central to national resilience, economic security and competitiveness.

For many years, shipping was taken for granted precisely because it functioned so effectively. Goods moved, supply chains held, and maritime capability remained largely invisible unless something went wrong. That era has now passed. The maritime domain is no longer simply the lifeblood of the global economy; it is now also one of the key arenas in which strategic competition is playing out. This is evident in disrupted sea lanes, attacks on commercial vessels, cyber threats, pressure on critical infrastructure, and the coercive use of geography.

In this context, maritime resilience is no longer a theoretical concern – it is a defining test of national resilience. For a country like the UK, the stakes are particularly high. We cannot be secure if we are not economically resilient. We cannot be competitive if our supply chains are vulnerable. And we cannot talk seriously about defence without also talking about the commercial maritime system that underpins it. 

Maritime Resilience as National Capability

In shipping, resilience is not an abstract concept. It is the ability to keep trade moving

while under external pressures. It depends on having the capacity, infrastructure, workforce and planning capability to absorb shocks and adapt at pace. Crucially, it is built in advance. Resilience can be improvised in the moment of crisis, but it is much better if built before the crisis.

From a defence perspective, this is fundamental. Military capability does not exist in isolation from commercial capability and capacity. Defence depends on supply, sustainment, movement and access. It depends on functioning ports, secure sea lanes, reliable logistics and the availability of commercial shipping services. A resilient commercial maritime base therefore forms part of the wider security posture of the state.

When shipping is disrupted, the effects are not confined to the maritime domain. They move rapidly through supply chains, into energy markets, onto factory floors and into households. With around 100,000 vessels calling at UK ports each year – roughly one every five minutes – maritime resilience is not an occasional concern, but a constant national requirement.

Competitiveness as a Strategic Asset

Too often, resilience and competitiveness are treated as competing priorities. In reality, they are mutually reinforcing, and both depend on shipping.

The UK maritime industry is a significant national asset. It directly employs nearly 100,000 people, supports over three-quarters of a million jobs across the wider economy, and contributes more than £16 bn in direct gross value added, rising to £46 bn overall. It outperforms other transport sectors in direct economic contribution, and in year-on-year growth.

Recent UK Chamber of Shipping analysis shows that the UK ranks 5th globally in maritime competitiveness, with particular strengths in our regulatory environment and governance, where we rank 4th, and in fleet and capital, where we rank 5th. This is a strong position, but not one that can be taken for granted. Our ranking must be continuously earned.

A competitive maritime industry is better able to invest, innovate, attract talent and respond to change. If the UK wants to remain a leading maritime nation, we need to think about our competitiveness in exactly those terms. It is about remaining an attractive place to do business, to invest, to innovate and to operate from. It is about the strength of the whole maritime ecosystem: operators, insurers, lawyers, financiers, brokers, ports and technology providers. The strength of that ecosystem will determine whether the UK is simply reacting to global change, or helping to shape it. 

Security at Sea: The Front Line of Disruption

Recent conflict in the Middle East has underlined that, irrespective of the geography, maritime security is not a distant issue. Attacks on commercial shipping and instability around key trade routes have immediate consequences for operational decision-making, trade flows, costs and confidence.

These developments sit alongside a broader risk landscape, including cyber threats, pressure on critical infrastructure, chokepoints and sanctions complexity. Commercial shipping is clearly not a combat force, nor can it be treated as somehow outside the security environment. Increasingly the sector operates at the front line of disruption in a contested geopolitical environment.

The implications extend well beyond the safety and security of the seafarers, ships and cargo, but for confidence and competitiveness too. Markets function most effectively where there is predictability; trade flows most efficiently where there is security. Investment follows environments that are stable and trusted. Where routes become less reliable, risks harder to manage or insure, and costs more volatile, the consequences are felt across the wider economy. The price of insecurity is therefore not paid only in risk, but in lost competitiveness.

Protecting commercial shipping is about more than safeguarding individual assets. It is about protecting the flow of trade itself, reducing friction, sustaining confidence and ensuring that insecurity does not become an accepted cost of doing business. Secure trade is competitive trade – and competitive trade depends on secure seas and freedom of navigation.

Partnership, Governance and Strategic Alignment

Mitigating these challenges requires closer alignment between government, industry and international institutions. Shipping is a global industry, and many of the risks it faces demand coordinated international responses. Common standards, predictable rules and stable governance frameworks remain critical.

In this context, the role of the International Maritime Organization is indispensable, providing the structure that enables shipping to operate safely, securely and competitively across jurisdictions. At the national level, stronger information sharing, more integrated resilience planning and a clearer understanding of maritime dependencies is essential.

There is also a broader strategic challenge. Industry must be more clearly recognised; not simply as part of the economy, but as a core component of national strategy. Countries that fail to recognise this are likely to be more exposed, less agile and less competitive.

Those that do will be better placed not only to withstand disruption, but to shape future conditions.

A Strategic Imperative

Shipping has always been fundamental to trade and prosperity. In today’s environment, it is equally fundamental to resilience, security and strategic competitiveness. That requires it to be better understood, better supported and more clearly recognised for the role it plays.

In a changing world, shipping is not on the margins of the UK’s strategic challenges. It is at the centre of them.
