Global current account imbalances feel like 2008 again
Current account imbalances are on the rise, renewing interest in one of the hottest topics in macroeconomics.
Economists like Maurice Obstfeld and Kenneth Rogoff argue that rising imbalances were a major factor in the crisis of 2008. More specifically, the global role of the dollar as the reserve currency inflated the value of US assets as capital from Asia and oil-exporting nations flowed in.
There was only a short period of normalization post-2008. The imbalances resumed their rise, especially during the first year of the pandemic.
As our chart shows, the US continues to be the main current-account deficit country; the rest of the world records surpluses. This doesn’t reflect any particular US trade weakness. As Ben Bernanke explained, the trade deficit is the tail of the dog, adjusting to a variety of variables: interest rates, the currency exchange rate, global financial flows, etc.
Ultimately, the rest of the world still craves US dollar assets and exports capital to the US economy.
