The Current Account Counts
Despite the US government’s recent upward revision to personal saving data, the overall national saving rate, which drives the current account, remains woefully deficient. And the major surplus countries – Germany, China, and Japan – have been only too happy to go along for the ride.
NEW HAVEN – In an increasingly interconnected global economy, cross-border trade and financial-capital linkages have come to matter more than ever. The current-account balance, the difference between a country’s investment and saving position, is key to understanding these linkages. The dispersion of current-account positions tells us much about the state of global imbalances, which are often a precursor of crises.
The same is true of trade tensions, such as those now evident around the world. Current-account disparities often pit one country against another.
Economies running current-account deficits tend to suffer from a deficiency of domestic saving. Lacking in saving and wanting to invest, consume, and grow, they have no choice but to borrow surplus saving from others, which gives rise to current-account and trade deficits with the rest of the world. The opposite is the case for countries with current-account surpluses. They are afflicted by subpar consumption, excess saving, and chronic trade surpluses.
