Are Global Trade Imbalances Signaling a Coming Economic Crisis?
Core argument: China’s current account surplus matches 2008’s share of world GDP despite its economy doubling in size, reflecting structural savings imbalances.
China’s reported surplus is much the same size now relative to the world economy as it was in 2008, though it is a far smaller share of its own GDP because the relative size of its economy has more than doubled. One difference is that former deficit European countries are now running a small surplus. More important differences are that net US liabilities reached 24% of global output in 2024 against a mere 6% in 2008, and that the US private sector has moved into balance. So, the domestic counterpart of its external deficits today is borrowing by the US government. Once roughly every 20 years, it appears, [the issue of global imbalances] comes to the fore. This is so for two good reasons. One is that current account imbalances drive protectionist sentiment. The other is that they are harbingers of financial crisis. In the 1980s, protectionist sentiment rose against Japan, which is also where the financial crisis struck. In the 2000s, the era of “the China shock”, protectionism began to rise against China and a financial crisis hit the western world. In the 2020s, protectionism is already here, in the US above all. But the financial crisis is not — or at least not yet.
