How persistent are global current account imbalances and which economies drive them?
Core argument: The US, China, Germany, and Japan together account for roughly two-thirds of global imbalances, with the US deficit equal to 4% of GDP in 2024, financed by capital inflows and portfolio investors seeking dollar assets.
Four economies—the US, China, Germany, and Japan—account for roughly two-thirds of global imbalances. The US deficit—equivalent to 4% of GDP as of 2024—has been financed by capital inflows and portfolio investors seeking dollar assets. Germany and Japan’s surpluses have been driven by high saving rates, joined by substantial surpluses in China beginning in the 2000s. Oil-exporting countries’ surpluses fluctuate with commodity prices, creating episodic contributions to global imbalances. In earlier decades, surpluses and deficits were more cyclical: countries moved in and out of surplus depending on business cycles, commodity shocks, and exchange rate movements. While there is no standard definition of persistence, the average duration of a deficit or surplus spell roughly doubled since the 1980s. Persistent surpluses over the past two decades have accumulated into very large net foreign asset positions for economies such as China, Germany, and Japan, with each holding net foreign assets equivalent to 3–3.5% of global GDP in 2024. Similarly, persistent deficits have built up into large net liability positions, most notably in the US where the NIIP stands at about -25% of global GDP in 2024, underscoring the central role of the US position in global balances (Figure 6).
