The U.S. has always paid its bills on time, but the overwhelming consensus among economists and Treasury officials of both parties is that failing to raise the debt limit would produce widespread economic catastrophe. In a matter of days, millions of Americans could be strapped for cash. We could see indefinite delays in critical payments. Nearly 50 million seniors could stop receiving Social Security checks for a time. Troops could go unpaid. Millions of families who rely on the monthly child tax credit could see delays. America, in short, would default on its obligations.

The U.S. has never defaulted. Not once. Doing so would likely precipitate a historic financial crisis that would compound the damage of the continuing public health emergency. Default could trigger a spike in interest rates, a steep drop in stock prices and other financial turmoil. Our current economic recovery would reverse into recession, with billions of dollars of growth and millions of jobs lost.

We would emerge from this crisis a permanently weaker nation. For about a century, America’s creditworthiness has been a major advantage over our economic competitors. We can borrow more cheaply than almost any other country, and defaulting would jeopardize this enviable fiscal position. It would also make America a more expensive place to live, as the higher cost of borrowing would fall on consumers. Mortgage payments, car loans, credit card bills—everything that is purchased with credit would be costlier after default.
