For the better part of two decades, the European Union has undergone a quiet but profound transformation in its external financial position, one that has largely escaped the kind of political and academic scrutiny reserved for the deficits of the United States or the surpluses of China. Between the early 2000s and the mid-2010s, the EU moved from a current account that was broadly balanced, fluctuating around zero, to a persistent and remarkably stable surplus of roughly 2.5 to 3 percent of its gross domestic product, a level it has maintained ever since with the single exception of the energy price shock in 2022. This shift did not happen because Europe suddenly became a spectacularly successful exporter in the manner of a developmental state, nor did it result from a deliberate policy of external mercantilism. Instead, it emerged from a series of traumatic adjustments following the global financial crisis and the euro area sovereign debt crisis, adjustments that permanently altered the investment behaviour of entire regions within the Union while leaving the saving habits of its wealthiest members largely undisturbed. The result is a Europe that saves more than it invests, not because its citizens are exceptionally frugal, but because its corporations and governments have, for different reasons and in different places, stopped building.
To understand the origins of this surplus, one must abandon the simplistic narrative that Germany’s export prowess is the sole driver. The data tell a more complicated and, in some ways, more troubling story. Between 2008 and 2012, the current account deficits of southern Europe—Greece, Spain, Portugal, Cyprus, and Malta—simply vanished. But they did not vanish because these countries experienced a wave of export-led growth or a sudden improvement in their productivity. They vanished because investment collapsed. In Spain, for example, the ratio of gross fixed capital formation to GDP fell from over 30 percent in 2007 to barely 18 percent by 2013, a decline driven overwhelmingly by the implosion of a housing bubble that had been financed by cross-border capital flows from northern European banks. The same pattern, albeit with different magnitudes, played out across the eastern member states that had joined the Union in 2004 and 2007. Countries like Latvia, Lithuania, Estonia, and Bulgaria had run enormous current account deficits in the mid-2000s, financed by foreign borrowing that fuelled a combination of real estate speculation and consumption booms. When the financial crisis cut off those capital flows, the adjustment was brutal and asymmetrical: investment fell, output contracted, and the current account swung into surplus or near-surplus within a matter of a few years. The crucial point is that these adjustments were not the result of successful rebalancing through structural reforms. They were the result of a sudden stop, a classic emerging market style crisis that happened to occur inside a monetary union. And once investment had fallen, it never fully recovered. Even today, more than a decade later, investment rates in southern and eastern Europe remain well below their pre-crisis peaks, and in many cases below the levels that would be needed to catch up with western European productivity standards.
While the deficit countries were adjusting through a painful compression of investment, the surplus countries of the Union were doing almost nothing to adjust in the opposite direction. Germany, the Netherlands, Denmark, and Sweden continued to run current account surpluses that, when summed together, have consistently exceeded 2 percent of EU GDP every year since 2006. But here again, the composition of these surpluses matters enormously for any policy diagnosis. In Germany, the surplus is driven primarily by households. German households save a remarkably high share of their disposable income, typically between 10 and 11 percent, a rate that has been remarkably stable over time and is unusually high by international comparison. This high household saving rate is partly a legacy of the Hartz labour market reforms of the mid-2000s, which created a low-wage sector and increased income uncertainty, and partly a response to demographic anxieties: a rapidly ageing population that fears inadequate public pensions has every incentive to accumulate private wealth. At the same time, German investment, particularly in the public sector and in digital infrastructure, has been chronically weak. The result is a structural excess of saving over investment that manifests as a current account surplus. In the Netherlands and Denmark, by contrast, the surplus is driven not by households but by corporations, and specifically by the retained earnings of large multinational enterprises and the enormous pools of capital accumulated in fully funded pension systems. These pension funds, which are among the largest in the world relative to GDP, generate a steady flow of saving that exceeds domestic investment opportunities, partly because the Dutch and Danish economies are small and open, and partly because the corporate sector in these countries has become extraordinarily efficient at generating profits that are not reinvested at home.
This divergence in the composition of surpluses across different EU member states has profound implications for policy. A surplus driven by household saving in Germany requires a different set of remedies than a surplus driven by corporate retained earnings in the Netherlands. Raising public investment in Germany would directly reduce the surplus by absorbing some of those household savings, but it would do nothing to address the Dutch surplus if Dutch multinationals continue to park their profits abroad. Conversely, integrating European capital markets more deeply might help channel Dutch pension fund assets into German infrastructure projects, thereby reducing both surpluses simultaneously, but this requires a level of financial integration and political coordination that the EU has so far proven incapable of achieving. The European Commission’s Macroeconomic Imbalance Procedure has repeatedly identified Germany, the Netherlands, and Sweden as having imbalances, but it has consistently stopped short of classifying these as excessive, largely because the deficits that once worried policymakers in the south have disappeared and the current account positions of the surplus countries are not, by themselves, creating obvious financial stability risks.
That judgment is defensible, but it is also dangerously complacent. The absence of an imminent crisis does not mean the surplus is benign. The fundamental problem with the EU’s external position is not that it threatens to trigger a global financial meltdown; the arithmetic of global imbalances suggests that the EU’s surplus, at roughly 0.5 percent of world GDP, can be absorbed without major disruption. The problem is what the surplus reveals about the underlying health of the European economy. A persistent current account surplus means that a country or region is consuming less than it produces, lending its savings to the rest of the world rather than using them to build productive capacity at home. This can be perfectly rational in certain circumstances, for example in a country that is saving for retirement in anticipation of demographic decline. But the EU’s surplus is not a simple function of demography. The International Monetary Fund’s External Balance Assessment, which attempts to estimate a current account norm based on observable fundamentals such as demographics, productivity growth, fiscal policy, and institutions, finds that the actual surpluses of Germany, the Netherlands, and Denmark far exceed their norms. For Germany, the gap is about 2 percent of GDP. For the Netherlands, it is over 6 percent. For Denmark, it is even larger. These gaps are not measurement error. They reflect the presence of unobservable structural distortions that depress investment, raise saving, or both, and that impose a real welfare cost on European citizens in the form of lower growth, lower consumption, and a slower pace of technological upgrading.
The most important of these distortions is the chronic weakness of domestic investment across much of the Union. It is common to hear that Europe has a savings glut, and there is truth to that claim, but the more precise diagnosis is that Europe has an investment deficit. The EU’s gross fixed capital formation as a share of GDP is not dramatically lower than that of the United States; both are around 22 percent of GDP. What differs is the composition and the quality of that investment. The United States allocates a much larger share of its investment to information and communication technology, intellectual property, and research and development, whereas the EU allocates a substantially larger share to real estate and traditional construction. In other words, Europe invests in bricks and mortar while America invests in software and chips. This pattern reflects a deeper problem: the European business environment, despite the single market, remains fragmented, risk-averse, and biased against the kind of disruptive innovation that drives productivity growth. Small and medium-sized enterprises struggle to scale across borders because of divergent national regulations, insolvency laws that punish failure excessively, and a venture capital market that is tiny compared to that of the United States. The result is that even when European savings are channeled into investment, that investment tends to be in low-productivity, low-risk assets, which does little to raise potential output or reduce the current account surplus.
Looking forward, there is every reason to believe that the EU’s current account surplus will persist for the foreseeable future, possibly for another decade or more. The baseline projections from the IMF, the European Commission, and the OECD all converge on a narrow range: the surplus is expected to decline only modestly, from around 3 percent of GDP in 2024 to perhaps 2.5 percent by the early 2030s. This persistence is driven by a combination of factors that are unlikely to change direction without deliberate policy intervention. On the fiscal front, many EU governments have announced medium-term consolidation plans that would, if fully implemented, raise the surplus by reducing public borrowing. But these plans lack credibility. The German government’s own fiscal strategy, for example, is built on nominal GDP growth assumptions that are significantly more optimistic than the consensus of the country’s leading research institutes; when those assumptions are corrected, Germany’s structural primary balance turns out to be much looser than advertised, and the planned consolidation from 2027 onwards may never materialize. Moreover, the recent increase in NATO’s defence spending target to 3.5 percent of GDP will, over time, force most EU governments to raise public spending on military capabilities, which will offset some of the planned consolidation. On the demographic front, the life-cycle hypothesis predicts that an ageing population will eventually reduce savings as retirees draw down their accumulated wealth, but that effect is likely to be delayed and muted. Evidence from household surveys across the EU shows that even people aged 75 and older continue to save positive amounts, partly because of uncertainty about long-term care costs and partly because in defined-benefit pension systems, which dominate most of the continent, the link between ageing and dissaving is weak. The demographic transition will reduce the EU’s current account surplus eventually, but not in the next five to ten years.
If the surplus is persistent and if it reflects an underlying investment deficit, then the appropriate policy response is not to target the current account directly through exchange rate manipulation or trade policy, but to implement a bold and coordinated agenda of investment-enhancing reforms. The Draghi Report on European competitiveness, published in 2024, provided a comprehensive roadmap, but its recommendations have so far been met with polite applause and minimal action. The agenda needs to become more aggressive and more politically salient. First, the single market must be completed, particularly in services, where barriers to cross-border provision remain pervasive and where the potential gains from integration are largest. A recent Bruegel study estimated that reducing services barriers to the level of goods barriers could raise EU GDP by several percentage points, and would almost certainly increase investment as firms expand to serve larger markets. Second, the EU should create a pan-European legal regime for the incorporation of young, innovative firms, a so-called Regime 0 that would allow startups to operate under a single set of rules across the entire Union, with a unified insolvency framework that reduces the personal cost of entrepreneurial failure. Such a regime would directly address the risk aversion that characterizes European investment. Third, the integration of European capital markets must move beyond the current piecemeal approach. A decentralized but powerful European Securities and Markets Authority, with direct supervisory authority over the largest cross-border financial institutions, could drive the convergence of listing rules, disclosure requirements, and investor protections that would allow European savings to find European investments more efficiently. Fourth, the EU’s fiscal rules, reformed only recently in 2024, need further reform to exempt public investment from expenditure ceilings, or at least to create a golden rule that treats public investment differently from current spending. The current framework still discourages governments from borrowing to finance infrastructure, education, and research, even when those investments have high social returns. Finally, labour market reforms should focus not on reducing worker protections, which would be politically toxic and economically questionable, but on reducing the costs of adjustment for firms, for example by making it easier to scale down failing ventures while maintaining generous unemployment insurance and retraining support for displaced workers.
There is one important caveat to this investment-focused agenda, and it is a caveat that is often overlooked in policy discussions. Not all reforms that raise investment will reduce the current account surplus. If the reforms take the form of a transition to fully funded pension systems, as some economists have advocated to deepen capital markets, the effect on the current account could be ambiguous or even perverse. Fully funded systems generate large pools of saving that may initially flow abroad if domestic investment opportunities are not sufficiently attractive. The experience of Denmark and the Netherlands, both of which have large funded pension systems and large current account surpluses, suggests that simply creating more saving does not automatically reduce the surplus; the surplus declines only when the saving is invested at home. The same logic applies to other investment-enhancing policies. The goal must be to raise the rate of return on domestic investment relative to foreign investment, or to reduce the perceived risk of domestic projects, so that European savings are deployed within Europe rather than exported to the rest of the world. This is a subtle but crucial distinction, and it implies that the policy agenda should prioritize reforms that improve the business environment, reduce regulatory uncertainty, and increase the productivity of European capital over reforms that simply increase the supply of saving.
The European Union’s current account surplus is not an emergency. It does not threaten to trigger a financial crisis, and it does not require immediate intervention to avoid a sudden stop. But it is a symptom of a deeper malady: an economy that has become structurally biased towards saving and against investment, that has failed to recover from the investment collapse of the global financial crisis, and that is gradually losing ground to the United States and China in the race to develop the technologies of the future. The surplus tells us that Europe is lending its savings to the rest of the world rather than using them to build the digital infrastructure, the clean energy systems, and the innovative firms that will determine its prosperity in the coming decades. That is not a crisis, but it is a failure of policy, and it is a failure that can be corrected. The tools are well understood, the political obstacles are formidable but not insurmountable, and the costs of inaction are rising every year. A Europe that invests more and saves less, that runs a smaller current account surplus but grows faster, that consumes more today while building more for tomorrow, would be a Europe that is not only more prosperous but also more secure, more cohesive, and more capable of meeting the challenges of a fractured world. The surplus is not the problem. The investment deficit is the problem. And it is time to treat it as such.
