Transatlantic Crossroads: The Future of US-EU Relations in a Fragmenting World Order


By Ramon Morell | www.ramonmorell.com | May 3, 2026

As someone who has spent decades navigating the complexities of multinational corporations across various continents — from boardrooms in Europe to operations in Latin America and beyond — and who dedicates his professional life to analysing global financial markets and tutoring traders in the discipline of reading price action and macro trends, I have always believed that understanding geopolitics requires the same rigour we apply to reading markets: cold analysis, pattern recognition, and the courage to call what you see, not what you wish to see.

The Tectonic Shift We Can No Longer Ignore

The transatlantic relationship — once the bedrock of the liberal international order built after 1945 — is undergoing its most profound transformation in over seven decades.

This is not a temporary disruption.

This is structural.

Since the return of Donald Trump to the White House in January 2025, the signals have been unmistakable. The United States has accelerated a trajectory that, in truth, began long before Trump: a reorientation of American strategic priorities away from Europe and toward bilateral, transactional arrangements driven by narrow economic nationalism.

Tariffs, defense burden-sharing ultimatums, skepticism toward multilateral institutions, and an openly confrontational posture toward the European Union as an economic competitor rather than an ally — these are not aberrations. They are the new operating system of American foreign policy.

For those of us in Spain and across Europe, the question is no longer «Will the old alliance survive?» The question is: «What replaces it, and are we prepared?»


The Economic Fracture: Trade War by Another Name

Let us be precise about what has happened. The escalation of US tariffs on European goods — steel, aluminum, automobiles, agricultural products, and increasingly digital services — has created a trade environment that more closely resembles managed rivalry than partnership. The EU has responded with its own countermeasures, but always cautiously, always hoping for de-escalation.

As Melchor Armenta and I have discussed many times when analyzing financial markets, hope is not a strategy. Markets punish those who confuse wishful thinking with positioning.

The fundamental economic divergence is real:

  • The US is pursuing reindustrialization through protectionism, massive fiscal spending, and energy dominance built on fossil fuels.
  • The EU is pursuing decarbonization, regulatory leadership (AI Act, Digital Markets Act, CBAM), and strategic autonomy — but without the fiscal unity or military capacity to back it up.

These are not complementary visions. They are, in critical sectors, competing models of 21st-century capitalism.


The Defense Dilemma: Europe’s Unfinished Homework

Perhaps nowhere is the transatlantic fracture more consequential than in defense and security. The war in Ukraine — now grinding through its fourth year — has exposed a brutal truth: Europe remains strategically dependent on the United States for its own continental security, even as the United States grows less willing to underwrite that security unconditionally.

The signals from Washington have been blunt. NATO’s Article 5 guarantee, once considered sacred, is now openly treated as conditional — contingent on defense spending targets, trade concessions, and political alignment.

Whether one considers this fair or unfair is irrelevant.

It is the reality.

Europe’s response has been significant but insufficient. The EU’s defense spending has increased, joint procurement initiatives have been launched, and countries like Poland, the Baltic states, and the Nordics have dramatically bolstered their military capabilities. But the core problem remains: Europe lacks a unified strategic culture, a common defense industrial base, and the political will to act as a single security actor.

From Málaga, where I am living, I observe this with particular concern. Spain, like much of Southern Europe, has historically invested less in defense and more in social cohesion.

That calculus is now under severe pressure.


The Geopolitical Chessboard: China, Russia, and the Middle Ground

The US-EU divergence does not occur in a vacuum. It occurs on a chessboard where other players — China, Russia, India, the Gulf states, the emerging Global South — are actively exploiting the fracture.

China benefits enormously from transatlantic disunity.

Beijing’s strategy has always been to deal with Washington and Brussels separately, playing one against the other. A divided West is a weaker negotiating partner on trade, technology standards, and global governance.

Russia, despite its economic weakness and the quagmire in Ukraine, benefits from any erosion of Western cohesion. Every crack in NATO, every trade dispute between Washington and Brussels, every populist movement that questions European integration — these are strategic assets for Moscow.

The great irony is this: the threats that should unite the US and EU are instead accelerating their divergence, because they disagree fundamentally on how to respond.


Five Scenarios for the Transatlantic Future

Drawing on the analytical discipline we apply to financial markets — where scenario planning is not an academic exercise but a survival tool — I see five plausible paths forward:

1. Managed Decline (Most Likely — 40%)
The alliance does not formally collapse but becomes increasingly hollow. NATO persists as an institution, but its operational relevance diminishes. Trade relations oscillate between tariff escalations and temporary truces. The US and EU cooperate selectively (counterterrorism, pandemic response) while competing aggressively in trade, technology, and energy. This is the «slow divorce» scenario — no dramatic rupture, but a steady erosion of trust and interdependence.

2. European Strategic Autonomy (Possible — 25%)
A major shock — perhaps a US withdrawal from a key security commitment, or a severe financial crisis — forces Europe to accelerate integration. The EU develops genuine defense capabilities, deepens fiscal union, and begins to act as an independent geopolitical pole. This is the scenario Brussels dreams of but has never had the political courage to pursue fully. It would require Germany, France, and yes, Spain and Italy, to make sacrifices that are currently politically unthinkable.

3. Renewed Partnership (Unlikely but Not Impossible — 15%)
A change in US political leadership, combined with a major external threat (Chinese aggression in Taiwan, a broader conflict in the Middle East), could catalyze a transatlantic renewal. This would require both sides to make significant concessions — the US accepting European regulatory sovereignty, Europe accepting genuine burden-sharing. History shows that alliances are often revived by shared enemies. But the domestic political dynamics in both the US and Europe make this increasingly difficult.

4. Fragmentation and Bilateral Deals (Possible — 15%)
The EU itself fragments under the pressure, with individual member states cutting separate deals with Washington. Poland and the Baltics align closely with the US on security; France pursues its own path; Germany oscillates. Southern Europe — Spain, Italy, Greece, Portugal — finds itself caught between competing gravitational pulls. This is the nightmare scenario for European integrationists, and it is more plausible than many in Brussels wish to admit.

5. Open Confrontation (Low Probability but High Impact — 5%)
A full-blown trade war, combined with a security crisis in which the US and EU find themselves on opposite sides (unlikely but conceivable in scenarios involving Turkey, North Africa, or differing approaches to China), could turn the relationship openly adversarial. This is the tail risk — improbable, but catastrophic if it materializes.


A View from Spain: Where Do We Stand?

As a Spaniard, as a European, and as someone who has spent a professional lifetime building bridges between the English-speaking and Spanish-speaking worlds, I feel compelled to offer a specifically Mediterranean perspective.

Spain occupies a unique position. We are a NATO member, an EU member, a gateway to Latin America and North Africa, and a country whose economic model — tourism, renewable energy, agriculture, services — is profoundly shaped by European integration. A weakening of the EU is not an abstract geopolitical concept for us. It is an existential economic threat.

At the same time, Spain has deep cultural and linguistic ties to Latin America — a region where US influence is being contested by China, and where European engagement has been historically insufficient. Spain could and should position itself as a bridge — not only linguistically or culturally, but strategically.

The financial markets —which I follow closely from passion and my job as associated professor of financial trading at UNED and a trading coach — are already pricing in a more fragmented world.

The diversification of reserve currencies, the rise of regional trade blocs, the increasing volatility of commodity markets — all of these are symptoms of a world that is moving away from the unipolar, transatlantic-centered order of the past three decades.


The Uncomfortable Conclusion

Let me be direct, as I believe a blog post worth reading must be.

The transatlantic relationship as we knew it is over. Not because of any single leader or policy, but because the structural forces driving the US and Europe apart — demographic divergence, energy asymmetries, technological competition, differing social models, and the rise of non-Western powers — are stronger than the institutional inertia holding the alliance together.

This does not mean the US and EU will become enemies. It means they will become something more complex: competitors who sometimes cooperate, partners who sometimes clash, and former intimates who must learn to live as respectful neighbors rather than members of the same household.

For Europe, and for Spain specifically, this demands a maturity we have not yet demonstrated. It demands:

  • Fiscal courage — investing in defense and technology even when it means difficult domestic trade-offs.
  • Strategic clarity — defining European interests independently of Washington, without the comforting illusion that America will always be there.
  • Diplomatic creativity — building new partnerships with the Global South, deepening ties with Latin America, engaging pragmatically with China and India.
  • Internal cohesion — resisting the centrifugal forces of populism and nationalism that threaten to tear the EU apart from within.

The world is not ending. But a chapter is closing. And the next chapter will be written by those who see clearly, plan rigorously, and act decisively.

As we say in the markets: the trend is your friend, until it isn’t. The trend of transatlantic convergence has reversed. The question now is whether Europe — and Spain within it — will adapt in time.
