A new whitepaper from DP World’s Marine Services unit has drawn attention to the strain on global maritime networks as geopolitical tensions, climate pressures and shifting trade policies increasingly challenge the movement of goods by sea.
Sources indicated on 25 September 2026 that more than 80% of world merchandise trade by volume moves by sea, and that the networks carrying an estimated $14 trillion of containerised goods are under test. The paper was published to mark World Maritime Day 2026 and focuses on resilience in maritime trade.
Scale and exposure
The figures cited underline the sheer scale of maritime trade and the exposure of international supply chains to external shocks. With the bulk of merchandise still ocean-borne, any sustained disruption to container networks risks ripple effects across manufacturing, retail and energy markets.
The whitepaper, as described in the report, frames those risks around three broad pressures: geopolitical disruption, climate-related impacts and changes to trade policy. It does not merely catalogue vulnerabilities but sets resilience as the central concern for operators and governments.
Operational pressures and responses
Shipping and port operators already face an array of operational challenges, the whitepaper notes, from rerouting and congestion to adapting infrastructure for more extreme weather. The emphasis is on adjusting practices and investments so the flow of containerised goods remains reliable despite shocks.
Industry responses discussed in the paper include strengthening logistical links, building capacity buffers and enhancing coordination between maritime stakeholders. The document highlights that resilience requires both private-sector action and policy support, particularly where critical chokepoints or specialised assets are involved.
Policy and strategic implications
Changes in trade policy are singled out as a shifting backdrop that can reframe route economics and investment priorities. The whitepaper suggests that policy volatility, alongside geopolitical friction, complicates long-term planning for ports, carriers and shippers.
Climate pressures add a further layer of uncertainty, affecting both the frequency of disruptive events and the need to adapt infrastructure. The combination of these forces means that resilience is not simply an operational aim but a strategic objective for national economies that depend on maritime trade.
A cautionary reminder
By publishing its analysis to coincide with World Maritime Day 2026, DP World’s Marine Services has put a spotlight on a systemic issue: a very large share of global trade travels by sea, and the networks that carry it are valuable and vulnerable. The reported estimate of $14 trillion in containerised goods emphasises why even limited disruptions can have outsized consequences.
The whitepaper, as reported, calls for closer cooperation among carriers, terminal operators and policy-makers to shore up networks. That cooperation, the paper implies, should focus on visibility across supply chains, investment in resilient infrastructure and policies that reduce unnecessary friction in international maritime logistics.
Looking ahead
If the observations in the paper are borne out by events, the maritime sector will face continued pressure to adapt rapidly. Operators may prioritise investments that offer flexibility and redundancy, while regulators will be asked to consider how rules and incentives can support a robust global trading system.
reports’s report of 25 September 2026 brings the debate into public view on a day dedicated to the sector. The scale of goods in transit underscores the strategic importance of maritime resilience for economies worldwide.
