98: What’s Wrong with Germany’s Trade Surplus?

Episode Summary

Executive Summary: The episode explains Germany’s unusually large trade and current account surplus as the result of multiple forces: euro adoption, reunification, labor-market reform, China-driven demand, and demographic savings behavior. Jeremy Zettelmeyer argues the surplus reflects chronic underinvestment and excess saving more than export virtue, and says Germany should reduce it through higher public and private investment rather than nationalism or protectionism.

Main Topics: Why Germany’s trade surplus became so large (Priority: 5/5): Zettelmeyer says Germany’s surplus grew dramatically from the late 1990s due to reunification shocks, euro-related dynamics, reforms, China demand, and aging-related savings behavior. The euro and exchange-rate constraints (Priority: 5/5): Membership in the euro prevented Germany from appreciating its currency even as competitiveness improved, helping the surplus remain elevated relative to what would likely happen under a floating exchange rate. Underinvestment as the deeper problem (Priority: 5/5): The guest argues the key puzzle is not export strength but why Germany saves too much and invests too little, leaving public infrastructure, wages, and domestic demand weak. China shock and global industrial demand (Priority: 4/5): Chinese industrialization increased competition for advanced economies but also boosted demand for German capital goods and manufactured inputs, benefiting German exporters. Labor markets, wages, and Eastern Europe integration (Priority: 4/5): Wage moderation and supply-chain integration with Eastern Europe likely restrained German wage growth and reinforced competitiveness. Rise of economic nationalism and industrial policy (Priority: 4/5): Trump-era trade politics helped legitimize stronger industrial policy in Germany, but Zettelmeyer warns this risks drifting into protectionism and distracting from macroeconomic fixes.

Key Arguments: Germany’s large surplus is a result of several overlapping forces, not a single cause. The euro helped keep Germany from seeing the currency appreciation that would normally curb a persistent surplus. German reunification weakened competitiveness in the 1990s, but reforms in the early 2000s later improved it. Capital flows to and from southern Europe affected Germany’s external balance, but do not fully explain the surplus’s persistence. The China shock had a dual effect: more competition, but also more demand for German capital goods. Germany’s aging population and rising precautionary savings helped sustain the surplus. The real economic issue is underconsumption and underinvestment, not the success of exports themselves. German export pride confuses national strength with the goal of maximizing trade surpluses. Trump-style criticism is rhetorically similar to German export nationalism, but the intelligent policy response is more public investment, not tariffs. Economic nationalism has reopened debate about industrial policy, but it risks displacing more important fiscal and investment reforms.

Data Points: Germany imports as share of GDP: around 40% - Used to illustrate how open the German economy is to trade. Germany exports as share of GDP: around 47% - Used to show Germany’s unusually high trade intensity. Germany trade surplus in 2018: 7% of GDP - The surplus highlighted as unusually large and politically contentious. U.S. trade and services imports/exports share of GDP: about 12% - Provided as a comparison showing the U.S. is far less trade-open than Germany. Period when surplus grew enormously: late 1990s onward - Zettelmeyer says the German surplus expanded sharply beginning in this period. High unemployment period: early 2000s - Germany entered the euro era with weak growth and high unemployment, prompting reforms. Period of renewed surplus growth: early 2000s through late 2000s - Surplus accelerated after reforms and before/through the global financial crisis. Public discussion of investment weakness: around 2013 - German policymakers began recognizing that domestic investment was too low.

Pivotal Quotes: "the real puzzle is why Germany saved what it earned abroad rather than using it for investment or consumption" — Jeremy Zettelmeyer: Explaining that trade surpluses reflect domestic saving and investment decisions, not just export strength. "being good at exports from a German perspective was about equivalent to winning the World Cup" — Jeremy Zettelmeyer: Describing Germany’s cultural pride in export performance and how it distorts policy thinking. "there is a very interesting analogy between the traditional German pride in its exports and President Trump's criticism of Germany" — Jeremy Zettelmeyer: Arguing that both German export nationalism and Trump’s rhetoric share a flawed economic nationalist mindset.

Implications: Germany should focus less on defending exports and more on raising wages, public investment, and private investment. For Europe, the debate shows how nationalism can mask structural imbalances and delay needed reforms.
