Have trade deficits funded consumption rather than business investment?
Core argument: Over 25 years, U.S. trade deficits and the mistaken belief that they chiefly fund business investment fueled a debt-financed rise in American consumption that contributed to the 2008 financial crisis and unsustainable deficit spending, with little boost to domestic investment or production.
For 25 years, trade deficits and the mistaken belief that they chiefly fund business investment have fueled a debt-financed increase in American consumption. This contributed to the 2008 financial crisis and unsustainable growth of deficit spending, while doing little to boost domestic investment or production. If the demand for business investment primarily drove trade deficits, real interest rates and trade deficits would rise with the demand for domestic business investment. But since 2000, real interest rates have tended to fall as trade deficits expand, and business investment has been uncorrelated with both, at least not until fiscal deficits started to devour savings. Unproductive spending slows growth, not the means necessary to fund it—greater taxes, interest expense, inflation, and future government spending cuts. If tariffs reduce trade deficits, it could raise interest rates, sending America’s precarious fiscal balance spiraling out of control.
