Trump’s tariffs, transatlantic uncertainty, and what it means for BSOs outside the EU

In our last blog post, ‘Buy European vs Open Europe: What Current EU Trade Debates Mean for BSOs Outside of the EU‘, we examined the strategic tension within Europe between industrial protection, strategic autonomy, and outward-facing trade openness. That debate now enters a new phase. Proposed tariff escalation from Donald Trump is emerging as a structural stress test for Europe’s trade model and, by extension, for Business Service Organisations (BSOs) operating outside the EU that depend on relatively stable transatlantic frameworks.

In early 2026, global trade policy has once again been jolted by renewed tariff activism from the United States. Policy proposals and political signalling around higher and more flexible tariffs, including broad-based import levies and the use of alternative trade authorities, have reintroduced a level of uncertainty not seen since the height of the 2018–2020 trade tensions.

For BSOs operating outside the EU, particularly in the UK, Asia, and emerging markets, this moment is not merely geopolitical theatre. It has direct implications for market access, supply chains, investment flows, and the evolving strategic logic behind ‘Buy European’ versus ‘Open Europe’ approaches discussed in recent EU policy debates.

This post considers what recent tariff developments mean, not only for Brussels and Washington, but for external partners navigating an increasingly fragmented and legally contested trade system.

The return of tariff volatility as a structural risk

Recent developments highlight several overlapping shocks to the global trade environment:

• Heightened legal and institutional scrutiny of executive tariff authority in the United States
• Policy pivoting toward new tariff instruments and alternative legal justifications
• Continued political signalling around broader and more aggressive tariff use

A February 2026 U.S. Supreme Court ruling limiting the use of emergency economic powers (IEEPA) to impose tariffs, alongside growing legal and congressional scrutiny of executive tariff authority, clarified that emergency economic powers legislation does not provide a blanket legal basis for imposing tariffs. This ruling constrains one of the most flexible legal pathways for rapid tariff escalation and introduces a new layer of legal contestation into trade policymaking.  This legal development underscores that tariff policy in 2026 is being shaped not only by executive strategy but also by judicial and legislative constraints.

Paradoxically, this does not necessarily reduce tariff risk. Instead, it increases policy volatility. When one legal mechanism is limited, policymakers may pivot toward alternative statutory tools, investigations, or temporary tariff measures. For businesses engaged in transatlantic trade, this creates a regulatory environment characterised by iteration rather than stability.

Implication for BSOs:
Tariff unpredictability is no longer a cyclical disruption, it is becoming a baseline operating condition in transatlantic trade governance.

The EU’s strategic dilemma: retaliate, negotiate, or re-regionalise?

The European Union is seeking clarity from Washington while signalling that unilateral tariff increases could strain existing trade understandings and cooperation mechanisms. At the same time:

• There is heightened caution in transatlantic trade engagement
• Retaliatory trade instruments remain politically viable
• There are greater policy coordination discussions among G7 economies

This matters for BSOs because EU responses to external tariff pressure tend to reinforce one of two strategic pathways:

1. Strategic Autonomy (‘Buy European’ Logic)

Higher external tariff risk strengthens the internal case for:

• Supply chain localisation
• Preference for EU-based suppliers
• Alignment with industrial policy and resilience agendas

2. Strategic Openness (‘Open Europe’ Logic)

Alternatively, tariff uncertainty can incentivise diversification of trade partnerships, including deeper engagement with the UK, India, ASEAN economies, and other third-country partners. In practice, the EU is increasingly pursuing diversification as a hedging strategy against geopolitical trade risk.

A Fragmenting Trade Map: The US–EU relationship is no longer the sole anchor

Tariff tensions and broader geopolitical shifts are already contributing to evolving trade patterns. For example, Germany’s trade with China has at times rivalled or exceeded its trade with the United States, primarily due to deep industrial integration and structural trade ties, with tariff uncertainty acting as a secondary diversification factor rather than a sole driver.

Similarly, European exports to the U.S. market have remained resilient overall, but with rising uncertainty surrounding future tariff regimes and regulatory conditions.

The emerging structural trend is not market exit, but risk diversification:

• Firms are not withdrawing from the U.S. market
• They are increasingly hedging against tariff and policy volatility

For BSOs outside the EU, this diversification creates new demand in areas such as:

• Trade facilitation and advisory
• Regulatory interpretation
• Market entry strategy
• Supply chain restructuring support

What this means specifically for BSOs outside the EU

Increased Demand for Trade Navigation Services

As tariff regimes become more fluid and legally contested, companies operating across the EU and U.S. require:

• Dual compliance strategies
• Scenario planning for tariff escalation or legal shifts
• Rules-of-origin and sourcing optimisation

BSOs positioned as policy interpreters, rather than purely operational intermediaries, gain strategic relevance in this environment.

Supply chain reconfiguration will accelerate

The renewed focus on tariffs as an industrial policy tool reinforces a broader trend toward geopolitical supply chain rebalancing. Likely developments include:

• Nearshoring to EU-adjacent regions
• Greater intermediary roles for the UK and EFTA-aligned economies
• Increased use of jurisdictions perceived as tariff-stable

The UK and other ‘third countries’ as strategic intermediaries

Tariff differentiation and bilateral arrangements mean ‘third countries’ may not be uniformly affected by U.S. tariff measures. This creates a potential strategic niche for non-EU BSOs to:

• Act as neutral trade bridges
• Host regional headquarters for tariff-sensitive firms
• Provide regulatory and geopolitical risk advisory

In a more fragmented trade landscape, institutional neutrality can become a competitive advantage.

The Legal Dimension: Trade policy is now politically and judicially contested

The 2026 Supreme Court ruling limiting the use of emergency economic powers for tariffs introduces a critical new variable: legal instability within trade policymaking itself. Combined with ongoing congressional debates over tariff authority, businesses now face:

• Policy reversals or redesign
• Legal challenges to trade measures
• Temporary or transitional tariff regimes with uncertain longevity

For BSOs, this reinforces the need to monitor not only trade policy announcements but also the legal frameworks underpinning them.

Strategic Outlook: From globalisation to managed trade blocs

The broader takeaway is not simply higher tariffs, but the acceleration of a more managed and bloc-oriented trade environment:

• United States: tariff signalling linked to industrial and strategic policy
• European Union: strategic autonomy combined with diversification
• Emerging economies: opportunistic alignment within shifting trade corridors

With EU–US trade representing one of the largest bilateral economic relationships globally, even incremental tariff shifts can generate disproportionate ripple effects across supply chains, investment planning, and regulatory strategy.

Final Thoughts: From tariff shock to structural realignment

The renewed focus on tariffs in U.S. trade policy is less a temporary disruption than a signal of a more fragmented and strategically managed trade environment defined by:

• Policy unpredictability
• Legal contestation of trade tools
• Regionalisation over pure globalisation

For BSOs outside the EU, the strategic implication is clear:

• Competitive advantage will increasingly derive from the ability to interpret and navigate political and legal trade risk, not just facilitate transactions.
• Organisations that reposition as geopolitical and regulatory trade advisors, rather than purely operational service providers, will be best placed to capture value in an era where tariffs are, once again, a central instrument of economic statecraft.

Please note: At the time of writing, several tariff measures and proposals remain in the signalling or policy development phase rather than fully implemented frameworks.
