H1 2025: Six Developments Reshaping Global Trade

The first half of 2025 has been one of the most turbulent periods for supply chains in recent memory. From renewed tariff wars to fresh geopolitical flashpoints, logistics professionals have had to contend with a constantly shifting landscape.

At the same time, structural challenges around skills, safety, and sustainability have continued to grow. Here we review six developments that defined H1 2025.

1. Tariffs return to the fore
The pause in US tariff escalation ended in August, with the White House reintroducing “reciprocal” tariffs that apply baseline duties of 10% to all countries and higher rates of 10–41% depending on origin. The UK sit at the low end, while Syria faces the steepest levels. Brazil has been singled out further, hit by an additional 40% levy. Canada also saw tariffs raised from 25% to 35% on certain goods, justified by Washington’s claim that Ottawa has not done enough to curb fentanyl flows.

The executive order applies from 7 August 2025, with a grace period allowing cargo already loaded onto vessels before that date to arrive until 5 October 2025. To add complexity, US Customs will also impose new fees on Chinese-built or operated vessels from 14 October, potentially forcing alliances such as the Ocean Alliance into costly fleet reshuffles. Carriers are already working through how to redeploy capacity to avoid penalties, with COSCO and OOCL particularly exposed.

2. New shipping alliances reshape networks
The recomposition of global shipping alliances in Q1 has reshaped carrier strategies. The launch of the Gemini Cooperation between Maersk and Hapag-Lloyd marked one of the most significant realignments in recent years, focused on achieving 90%+ schedule reliability. Shippers are already seeing more dependable services, but questions remain about whether premium pricing will follow.

Other alliances, particularly Ocean and THE Alliance (now Premier Alliance), are recalibrating networks, with competition sharpening across Asia–Europe and transpacific trades. For shippers, the alliance changes mean rethinking service contracts and adapting to new network structures that could endure for much of the decade.

3. Houthi attacks deepen Red Sea crisis
The Red Sea crisis, triggered by Houthi rebel attacks, has now stretched on for nearly two years. In July 2025 the threat escalated further with the sinking of the Magic Seas, a Greek-operated vessel targeted for its links to companies calling at Israeli ports. Analysis suggests that one in six vessels globally could now be considered threatened under the Houthis’ broad definition of violators.

For container lines, this effectively rules out a return to Suez Canal routings before 2026 — and possibly not until 2027. Rerouting around the Cape of Good Hope adds up to two weeks to Asia–Europe journeys, pushing up costs and insurance premiums, and putting additional strain on fleet capacity. The Red Sea instability has been a reminder of how localised conflicts can have global consequences for supply chains.

4. Logistics skills shortages persist
The UK continues to face a significant shortfall in logistics skills, with the Road Haulage Association estimating a deficit of around 50,000 HGV drivers. The ONS also reports 6,000 fewer courier and delivery drivers than the previous year. With 55% of HGV drivers aged between 50 and 65, the demographic imbalance remains a long-term concern.

Factors include reduced access to EU workers post-Brexit, poor industry perception, and limited uptake of government training schemes. Although the crisis is not as acute as during the height of the pandemic, the ageing workforce and lack of young entrants mean structural shortages will continue. Rising wage costs, recruitment struggles, and bottlenecks in road transport all add to the burden on UK supply chains.

5. EV shipping challenges raise alarm
The growth of electric vehicle (EV) trade has created new safety risks at sea. Several high-profile fires on car carriers have been linked to lithium-ion batteries, sparking concern among insurers, regulators, and shipowners. Insurers are pushing for tougher loading protocols, enhanced crew training, and more advanced fire suppression systems.

For supply chains, this adds cost and complexity to automotive logistics, with carriers facing higher insurance premiums and the need to retrofit vessels. It is also slowing the momentum of EV exports, just as demand for cleaner vehicles accelerates globally.

6. Sustainability regulations tighten
Sustainability regulation is reshaping procurement strategies. The EU’s Carbon Border Adjustment Mechanism (CBAM) is beginning to impact trade in carbon-intensive products such as steel, aluminium, and cement, with importers required to report embedded emissions.

At the same time, sustainable aviation fuel (SAF) is moving toward a tipping point. UK and EU mandates are pushing airlines to integrate SAF into their fuel mix, with new investments underway to scale production.

While tariffs and geopolitics grab headlines, sustainability is quietly becoming a decisive factor in supplier choice, cost structures, and long-term resilience planning. For many organisations, compliance with emissions and ESG frameworks is no longer optional but critical.

Outlook
H1 2025 has exposed the vulnerability of supply chains to political shocks, armed conflict, safety risks, and structural labour shortages. Tariffs, alliances, and attacks have disrupted networks, while long-term challenges around sustainability and skills remain unresolved.

The message for supply chain leaders is clear: resilience, agility, and visibility will be critical in the second half of 2025, as disruption becomes the new normal.

H1 2025 has underlined how vulnerable global supply chains have become and staying ahead demands visibility, expertise, and a trusted partner by your side.

Asian Cargo Surge Threatens to Overwhelm North Europe Ports

North Europe’s container gateways face a turbulent August and September as a surge of inbound cargo from Asia collides with already stretched terminal operations.

Strong import demand through the first half of the year has driven double‑digit growth in volumes, with the peak season now set to push many ports to breaking point.

For months, operators have battled chronic congestion, with delayed vessel arrivals throwing schedules into disarray and container yards struggling under sustained high occupancy. The anticipated wave of summer imports will magnify these pressures, raising the risk of longer delays and service disruption well into the autumn.

Rising volumes, falling reliability
Exports from Asia to Europe have maintained strong growth into the second half, with China–EU shipments in particular climbing at a double‑digit rate year‑on‑year. This pattern typically sees July sailings arrive in Europe through August and September, concentrating peak loads into an already fragile network.

Schedule reliability has deteriorated sharply. On‑time arrivals for Asia–North Europe services have dropped from more than two‑fifths in May to less than one‑third in July. Larger vessels deployed to circumvent southern Africa are adding to the strain, extending berth stays and raising yard utilisation. Prolonged transit times are feeding greater volatility and unpredictability across the supply chain.

Not all ports are equally affected, but the most severe congestion has been concentrated at London Gateway, Antwerp, Hamburg, and Rotterdam. Antwerp and Hamburg are further hampered by high barge delays, worsened by low water levels restricting inland waterway capacity. Some gateways still report healthy throughput, yet overall capacity buffers are now minimal.

Carrier work‑arounds
Lines are adjusting strategies to ease bottlenecks. Some are replacing transhipment legs with direct calls to Scandinavian ports, reducing container moves by two‑thirds on certain routes. Others are diverting volumes away from heavily congested hubs or shifting calls to less‑utilised terminals such as Le Havre, Zeebrugge, Bremerhaven, and Wilhelmshaven.

Carriers are also moving boxes from deep‑sea terminals into inland depots to free yard space, although low Rhine water levels continue to limit barge utilisation. With inland capacity already tight, this offers only partial relief.

While tactical adjustments may prevent a complete choke‑point, the outlook for the remainder of the summer remains challenging. Persistent high demand, combined with limited progress in clearing congestion, suggests the sector will remain under pressure until at least the final quarter of the year.

Metro’s sea freight teams are actively monitoring port performance, vessel schedules, and rate movements across all major trade lanes. We work with customers to secure priority bookings, optimise equipment and container allocation, and design alternative routings to avoid bottlenecks and minimise disruption.

Tighter Transshipment Rules Put Southeast Asia’s Supply Chains Under the Spotlight

The latest US trade agreements have introduced tougher measures targeting the rerouting of Chinese goods, reflecting heightened scrutiny on supply chain flows through Southeast Asia.

While these rules are designed to curb “origin washing” — the mislabelling of goods to disguise their true country of origin — the underlying reality is more complex, with genuine production shifts also reshaping regional trade.

Much of the recent manufacturing growth in  Southeast Asia countries including Vietnam and Indonesia stems from legitimate relocation of production, rather than disguised transshipment. Chinese manufacturers, facing steep US tariffs since President Trump’s first term, have increasingly invested in factories across Southeast Asia, seeking competitive labour costs and tariff advantages. This process has enabled these host countries to increase domestic value‑added in exports while reducing reliance on Chinese‑sourced inputs.

In Vietnam, for example, the domestic share of value in strategic exports to the US has risen steadily, driven by sustained foreign investment and capacity building. This mirrors China’s own transformation after joining the WTO, when its foreign content in exports fell significantly over time as local supply chains matured.

The New US Approach to Transshipment
In their recent trade deal President Donald Trump announced a 20% tariff on Vietnam’s exports, but 40% on any “transshipping” of production elsewhere. In the agreement with Jakarta, if there is any rerouting of output from a higher-tariff country, then the evaded duty will be added to the 19% rate for Indonesia.

This aims to prevent goods subject to heavy US duties from entering the market via a lower‑tariff partner after minimal additional work. In practice, enforcement involves tighter certification regimes, closer customs inspections, and stricter rules of origin documentation.

While legitimate outsourcing is allowed under WTO rules, the US measures blur the line between blocking illegal rerouting and discouraging lawful production relocation. This creates uncertainty for businesses investing in diversified regional supply chains.

Implications for Supply Chain Strategy
The new measures could:

  • Increase compliance costs – Exporters must strengthen origin verification, certification, and documentation to avoid tariff penalties.
  • Slow diversification plans – Firms considering shifting production from China to Southeast Asia may reassess timelines and risk exposure.
  • Disrupt regional supply chains – Interconnected production networks risk being treated as transshipment hubs, even when substantial value is added locally.

For Southeast Asian economies, the challenge lies in demonstrating clear value addition and avoiding the perception of serving as simple conduits for Chinese goods.

If these rules are applied broadly, they could reshape the regional manufacturing landscape. Instead of encouraging investment in new production capacity, the measures may discourage multinational manufacturers from fully committing to Southeast Asia for fear of tariff exposure.

For supply chain planners, this environment demands careful mapping of production footprints, investment in compliance infrastructure, and contingency planning for potential trade disruptions.
