Global Trade Imbalances: Why a 'Great Rebalancing' Is Inevitable

Global trade imbalances involving major economies such as the United States, China, Germany and others cannot persist indefinitely without triggering painful adjustments, according to new analysis by Michael Pettis, a senior associate at the Carnegie Endowment for International Peace. Persistent surpluses in China and Germany are matched by the world’s largest deficit in the United States, creating structural tensions that risk sharp contractions in global demand if left unaddressed.

Economists widely agree that large, persistent trade imbalances are unsustainable, but policymakers in Beijing, Washington and Brussels have failed to agree on a coordinated correction. China blames excessive U.S. consumption and fiscal deficits, while the U.S. points to foreign industrial policies, currency practices and restrictive trade barriers. European leaders emphasize multilateral rules and greater domestic demand in surplus countries. Without alignment, prospects for a preemptive adjustment remain slim, increasing the likelihood of disorderly corrections.

Historic episodes show that trade imbalances of this magnitude rarely unwind smoothly. A century of examples—including the 1920s, 1970s Latin America, 1980s Japan and Germany, and the Asian financial crisis—demonstrates that imbalances typically end in crisis, recession or prolonged stagnation. In the 1920s, U.S. surpluses and European deficits led to protectionist measures, currency devaluations and ultimately the Great Depression. The U.S. bore a disproportionate share of the costs, with exports collapsing, investment imploding and widespread bank failures.

During the 1950s and 1960s, imbalances between the U.S. and recovering European and Japanese economies were managed through capital controls and investment-led growth, allowing debts to remain sustainable and trade gaps to close gradually. However, this benign outcome relied on exceptional conditions—strong productivity, limited capital mobility and coordinated reconstruction efforts.

More recent cases have followed the painful pattern. The 1970s oil shocks generated petrodollar surpluses that were recycled as debt to Latin American economies, leading to overvalued exchange rates, debt crises and lost decades of growth. In the 1980s, Japan’s rapid productivity gains drove massive trade surpluses, excessive domestic investment and asset bubbles. The Plaza Accord of 1985 attempted to rebalance through currency appreciation, but resolution came only with Japan’s asset collapse and prolonged stagnation in the 1990s.

China now faces similar pressures. With growth reliant on exports and investment, authorities have incentives to maintain large surpluses, but rising debt, demographic shifts and productivity challenges increase vulnerability. Meanwhile, the U.S. remains exposed through its persistent deficit, while Europe’s fragmented policy response limits its ability to influence outcomes. Analysts warn that without coordinated action, the adjustment burden will fall disproportionately on deficit countries or those with fragile financial systems.

The lesson from history is clear: trade imbalances of this scale do not fade away quietly. When surplus and deficit economies fail to coordinate adjustments, the costs are ultimately borne through crisis, recession or prolonged underperformance. The question is not whether a rebalancing will come, but who will bear its brunt.
