The End of Pax-Americana?
German Chancellor Friedrich Mertz’s recent declaration of the “end of Pax Americana” is a predictable piece of political theatre. Facing a increasingly restive disillusioned electorate and a stagnant economy Mertz tried to present a compelling villain for Europe’s woes, and Washington, with its new-old administration, is a perfect target. His pronouncement, no doubt spurred by the punitive realities of agreements like July’s so-called Trade Rebalancing Agreement—a capitulation reframed as a compromise—resonates with a European political class weary of perceived American predation.
This pattern of casting the transatlantic relationship as a slow-motion divorce is a perennial favorite. Commentators point to Washington’s brazen industrial nationalism, Brussels’ earnest talk of “strategic autonomy,” and the acrimony of tariff disputes. Even the recently released US National Security Strategy seems to make explicit the US’ own preference for a mutual separation. But while the narrative of a clean break—of Europe and the US going their own separate ways—may be emotionally and politically seductive on both sides, it is also a profound fantasy.
Beneath the political rhetoric and trade spats lies a stubborn, colossal, and often ignored reality: the transatlantic economies are conjoined by a financial bedrock so deep that divorce is not just painful, but functionally impossible. There are roughly seven trillion reasons—measured in direct investment—why this marriage, however strained and at times abusive, endures.
Yet to stop at the fact of mutual dependency is to miss a darker, more salient truth. This deep integration is not a partnership of equals. It is the foundation upon which a relationship of profound and growing asymmetry is built. The United States, recognizing the lock-in effect of these trillions, is increasingly exploiting the inherent weaknesses in the European project, particularly the euro’s flawed architecture, to tilt the financial and industrial playing field decisively in its favor. Europe’s dilemma is that its leaders can lament the end of an era, but they remain trapped within the unyielding structures that era created.
The Illusion of Autonomy and the Reality of Capitulation
Mertz’s rhetorical flourish did not emerge from a vacuum. It is the culmination of years of accumulating pressure, crystallized in the Trump administration’s 2025 “rebalancing” agreements. To call these deals mere trade pacts is to misunderstand their purpose. They are instruments of economic subordination, drafted with a contractual precision that echoes colonial tribute systems. For Europe, the July deal was a stark defeat. Baseline tariffs of 15% on most EU exports, with steel and aluminum shackled at 50%, eviscerated profit margins overnight.
The industrial logic is brutally transparent. Faced with ruin, Europe’s manufacturing crown jewels—its German automakers, French aerospace giants, Italian machinery exporters—have little choice but to relocate advanced production to US soil. They are lured by the subsidies of the Biden-era Inflation Reduction Act and bludgeoned by Trump-era tariffs. The result is a one-way transfer: production, high-value jobs, and critical technology flow westward. What remains in Europe risks being hollowed-out assembly lines dependent on imported, US-made components.
This predation extends beyond manufacturing. Energy dependency has been meticulously reconstituted. Europe is now contractually compelled to purchase $750bn of American LNG, at nearly twice the cost of pre-sanctions Russian pipeline gas, while financing the billions required for new regasification terminals. Simultaneously, Washington secured exemptions from the EU’s Carbon Border Adjustment Mechanism for its own exports, deftly turning European climate ambition into a weapon of asymmetric advantage.
The third chain is military. A mandated $600bn in US arms imports, sold as “burden-sharing,” entrenches a reliance on American hardware that guts the prospect of a truly autonomous European defense technological and industrial base. Europe may fly its own flag, but it cannot field a modern army without Washington’s supply chain, effectively rendering its remaining arms firms subsidiaries of Raytheon and Lockheed Martin.
The $7 Trillion Bedrock: Why Divorce is a Fiction
Given this extractive reality, the urge for divorce is understandable. But here, the narrative collides with an immovable object: the staggering scale of mutual financial ownership. Over the past five years, U.S. direct investment abroad has consistently exceeded $6 trillion. Europe accounts for the lion’s share—roughly 58%, or close to $4 trillion. Conversely, foreign direct investment into the U.S. stands at about $5.7 trillion, with Europe supplying nearly two-thirds. These figures, sourced from Bureau of Economic Analysis (BEA) data, represent not portfolio flows but deep entanglement: ownership stakes, integrated profit streams, shared intellectual property, and tangled supply chains.
This is not marginal exposure that can be unwound with policy tweaks. It is the economic equivalent of shared organs. A significant portion of this capital resides in the complex plumbing of global finance—in holding companies, financial affiliates, and special-purpose entities clustered in jurisdictions like the Netherlands, Luxembourg, and Ireland. Often dismissed as accounting fiction, these conduits are the vital infrastructure of transatlantic capital. They enable American multinationals to manage global operations and European firms to invest in the U.S., often for onward investment into third markets in the Global South. Untangling this web of relationships would be equally as intractability for the drafters of the recent US National Security Strategy however much they say they wish to do so.
Analyses by the OECD and IMF that reallocate investment to “ultimate host economies” confirm an underlying truth: strip out the conduit jurisdictions, and the transatlantic bloc’s overwhelming mutual exposure remains vast. This complex web completely undermines the idea of separate economic orbits. Disentanglement would require a traumatic, wholesale restructuring of corporate balance sheets, legal domiciles, and financial systems built over decades—a project with no political constituency among the corporations that dominate both economies.
Indeed, the past five years of geopolitical tension have done nothing to slow this integration. Despite the Inflation Reduction Act, “de-risking” talk, and tariff wars, transatlantic investment stocks have continued to climb. This reveals a relationship defined not by romantic interest but by dense, rational, financial interdependence. Firms rely on access to each other’s markets for financing, tax efficiency, and global reach. Governments may talk autonomy, but they are ultimately constrained by the interests of corporations with profoundly transatlantic balance sheets.
Asymmetry by Design: The Euro’s Fatal Flaw
This deep integration, however, is the stage upon which American advantage is played out. The relationship is symbiotic but not equal. Its fundamental asymmetry is rooted in monetary architecture. The euro was launched as a political project with a critical economic omission: it lacked the foundational institutions of a genuine fiscal union—no common treasury, no central fiscal authority, no unambiguous lender of last resort. This design flaw ensured that in times of crisis, member states would be forced to rely on international capital markets, where the US dollar is supreme.
The sovereign debt crises of the 2010s were not just economic disasters; they were mechanisms of financial capture. Weakened European states implemented austerity, selling off assets and restructuring economies under duress. Their banking systems, destabilized, became more deeply intertwined with and dependent on U.S. financial capital and dollar-denominated wholesale funding markets. The European Central Bank’s efforts to backstop the system, while successful in preventing collapse, further enmeshed eurozone stability within the global dollar system.
Thus, the grand project to create a rival to dollar hegemony instead locked Europe into a subordinate position within the global dollar ecosystem. The euro, without a unified sovereign behind it, is a currency that depends on the kindness of strangers—and the deepest, most powerful stranger is the dollar-based financial ecosystem. This structural weakness is relentlessly exploited. US financial institutions dominate currency and derivatives markets; dollar clearance provides unparalleled leverage for sanctions policy; and in times of global stress, the flight to dollar liquidity reinforces American financial centrality.
Washington’s recent policy suite—from the IRA to the trade rebalancing deals—is not a departure from this system but its logical extension. It uses America’s market size, financial depth, and the dollar’s “exorbitant privilege” to pull high-value economic activity onto its shores, knowing Europe lacks the integrated fiscal and financial tools to mount an equivalent response. The EU’s response is fragmented, slow, and often self-cancelling, hamstrung by the very institutional divides the euro was supposed to overcome.
Managed Friction, Not Rupture
The conclusion is bleakly pragmatic. A clean divorce is off the table. The $7 trillion in shared assets makes rupture economically cataclysmic and politically unthinkable. Instead, the transatlantic future is one of managed friction: loud political rhetoric, selective decoupling in strategically sensitive sectors like semiconductors and critical minerals, and the relentless exploitation of European institutional weakness by a US focused on its own industrial and financial advantage.
The relationship will endure, but increasingly on American terms. Europe will remain a premier destination for US capital precisely because it is a wealthy, stable market whose monetary design ensures it cannot mount a fundamental challenge. When Washington debates the cost of defending Europe, it is weighing more than treaty obligations; it is protecting the security environment for its $4 trillion in direct investment. The security guarantee is, in part, a subsidy for capital.
Chancellor Mertz is correct that Pax Americana, in its old, generously hegemonic form, is over. What has replaced it is not a new order of sovereign equals, but a more nakedly transactional and extractive framework. Europe is bound to the United States not by sentiment but by a financial gravity too strong to escape. Its leaders can declare independence from the podium, but they return to cabinets filled with balance sheets that tell a very different story—one of profound dependency, written in the unassailable language of trillions. The marriage will continue, even if the romance is dead.
