Lagarde warns Europe's post-war growth model is eroding beyond return

Christine Lagarde, president of the European Central Bank, told an audience in Geneva on Wednesday that the economic model which delivered prosperity to Europe for eight decades is coming apart. The conditions that drove continental growth, she said, are "eroding" and "unlikely to return to the form we once knew."

The assessment, delivered at the World Economic Forum's International Business Council, was unusually direct for a central bank president. Lagarde identified three pillars underpinning Europe's post-war success: expanding global trade, manufacturing built on access to cheap energy, and a stable, rules-based international order backed by American military power. All three, she argued, are now weakening.

Three pillars, all crumbling

The first pillar, trade expansion, has been under pressure for years. Lagarde noted that more than 2,500 trade restrictions were implemented globally last year alone. That figure, tracked by the World Trade Organization, reflects a sharp acceleration in protectionism that predates the current US administration but has intensified markedly since Donald Trump returned to the White House.

The second pillar, cheap energy, disintegrated when Russia cut pipeline gas flows to Europe in 2022. European manufacturers, particularly in Germany, had organised their competitiveness around Russian hydrocarbons at prices that no longer exist. The third pillar, the American security guarantee, is now in question as the Trump administration threatens to withdraw from NATO and demands that European allies spend far more on defence.

Lagarde's argument is that these three developments are not separate disruptions but interconnected failures of the same system. "That environment allowed European supply chains to deepen, and enabled firms to organise investment around efficiency rather than resilience," she said. "Today, that global order is under pressure. Geopolitical tensions are bringing critical dependencies and chokepoints into sharper focus, while Europe faces growing security threats on its doorstep."

The tariff damage

The trade pillar has suffered the most visible recent blow. Shortly after returning to office, Trump imposed a 20% baseline tariff on goods imported from the European Union. That rate was later reduced to 15% when Brussels and Washington agreed on a trade deal, but the agreement's durability remains uncertain. How certain European goods, notably steel, will be taxed by Washington is still unclear.

A 15% tariff on EU exports to the United States is not a marginal cost. For exporters operating on thin margins, it erodes competitiveness against domestic American producers and against rivals from countries with lower or zero tariff rates. The uncertainty may be more damaging than the tariff itself: firms cannot plan investment when the rules governing their largest export market might change with a presidential statement.

The broader point Lagarde was making is that the era in which trade liberalisation was the default assumption of international commerce has ended. For decades, European companies could assume that market access would gradually expand. That assumption shaped supply chains, investment decisions and corporate strategy across the continent. Reversing it requires a fundamental rethinking of how European firms operate.

Security and the cost of capital

The security dimension of Lagarde's argument is less frequently discussed in economic terms but is central to her case. When the American security umbrella was credible, European firms could treat geopolitical risk as a secondary consideration. Investment flowed to where it was most efficient. Capital was safe because deterrence was assumed.

That assumption no longer holds. Russian military aircraft have increasingly encroached on European airspace. The US-Iran war has created new security threats for the region. The Trump administration has issued threats to withdraw from the military alliance and has even suggested bringing NATO territory under Washington's control by force, a statement that would have been unthinkable from any previous American presidency.

"When economic dependencies can be weaponised or when perceptions of deterrence weaken, concerns about resilience enter economic decisions directly," Lagarde said. "Firms invest less when capital is seen as less safe, weighing on output and consumption."

The causal chain matters. It is not simply that Europe must spend more on defence, though it must. It is that the erosion of the security guarantee changes the risk calculus for every investment decision on the continent. Capital becomes more expensive. Returns must be higher to compensate for perceived instability. Projects that would have proceeded in a stable environment are shelved or relocated.

The AI mistake Europe cannot repeat

Lagarde's sharpest warning concerned artificial intelligence. "Europe largely missed out on the first digital revolution, as the commercial gains from the spread of information and communication technologies were captured disproportionately elsewhere," she said. "We cannot afford to repeat that experience with artificial intelligence, the second digital revolution."

The numbers behind that warning are stark. Europe's 34 most valuable listed technology companies have a combined market capitalisation of roughly €1.37 trillion. The United States' so-called Magnificent Seven stocks, a group dominated by AI-adjacent firms, have a combined market value exceeding $23 trillion. That is not a gap. It is an order of magnitude.

Europe missed the first digital revolution for structural reasons: fragmented capital markets, risk-averse investors, regulatory environments that penalised experimentation, and a culture that rewarded stability over scale. Many of those conditions persist. Lagarde acknowledged there were "encouraging signs" that European firms are investing in AI, but she questioned whether Europe can "create the conditions for that investment to spread and scale."

The question is whether anything has genuinely changed. Europe still lacks deep capital markets that can fund companies from startup to global scale. Venture capital exists but remains a fraction of what is available in the United States. The EU's regulatory instinct, visible in the AI Act and the Digital Markets Act, is to constrain first and enable second. That may protect citizens, but it does not build trillion-dollar companies.

EU Inc and the scale problem

Lagarde pointed to one specific proposal: "EU Inc.", an optional EU-wide corporate legal form that would allow companies to incorporate once and operate under a single set of rules across the bloc. She also noted that capital market reforms are being devised to help European companies scale across the continent.

The logic is straightforward. Europe's single market is enormous in population and GDP, but it functions as 27 separate legal and regulatory environments. A company that wants to operate across the EU must navigate different corporate law, different tax treatment and different regulatory expectations in each member state. The result is that successful European companies often relocate to the United States, where a single incorporation gives access to a market of 330 million people and the world's deepest capital pools.

"Turning European size into European scale," Lagarde said, "would help innovative firms grow at home, allow new technologies to spread faster and boost productivity. In doing so, it would help make domestic demand a more lasting engine of growth."

The phrase "European size into European scale" is concise enough to become a refrain. The problem it describes is real. The EU's single market remains incomplete in services, digital infrastructure and capital allocation. Whether the political will exists to complete it is a different question. Capital market integration has been on the agenda for decades with limited progress, because it requires member states to cede regulatory authority and tax advantages they have no appetite to surrender.

Europe's own protectionism

Marco Forgione, director general of the Chartered Institute of Export and International Trade, offered a blunter assessment. "The internal market within Europe is free, but trading into Europe is very far from free, and it's a very protectionist environment," he told CNBC's Squawk Box Europe on Wednesday.

Forgione's point is that Europe complains about American tariffs while maintaining its own barriers to external trade. The EU's common external tariff, anti-dumping procedures and regulatory requirements for imports all function as protection for domestic producers. That is not inherently wrong; every major economy protects certain sectors. But it sits uncomfortably alongside Lagarde's call for a return to trade expansion as a growth driver.

He also identified a competitive challenge that European policymakers prefer to understate. "Competition from China and the likes, who have moved way up the value chain with regards to manufacturing, is a real challenge," Forgione said. Europe's industrial advantage was never just cheap energy. It was technological sophistication and product quality. As Chinese manufacturers move into higher-value products, from electric vehicles to advanced batteries, that advantage narrows.

"Fundamental changes, both political and economic, are required if Europe is going to break free from the sort of stasis that it's been in for decades and really start to see growth in its economy," Forgione added.
