What Happens If America Can’t Pay Its Debt?

America owes more than $40 trillion. It can print its own money, so in theory it can never run out. And yet, in 1979, the United States actually failed to pay some of its debts on time, partly because of a broken word processor. Sometime in 2027, America hits its borrowing limit again. So what would really happen if America stopped paying? In this video we walk through it step by step: how the debt ceiling works, the X-date, who might not get paid on day one, what a default would do to Treasury bills, money market funds, stocks and jobs, the 1979 accidental default, the strange market reaction to America's 2011 downgrade, why America's safety cushion is getting thinner, the "soft default" nobody notices, and what it all means for your mortgage, retirement, cash and Social Security.
