It didn’t take long for the U.S. to rack up another trillion dollars of debt

It has taken a little more than six months for the U.S. national debt to grow by a trillion dollars, a quick clip that has little precedent over the nation’s recent history. 

Last week, the debt hit $21 trillion for the first time, rising from the $20 trillion mark it notched on Sept. 8. The debt is guaranteed to go higher, with President Donald Trump having signed a debt-limit suspension in February, allowing unlimited borrowing through March 1, 2019. Economists expect wider deficits to result from the tax cut Trump signed in December. 

While a trillion-dollar increase over roughly six months isn’t unprecedented — there was one in 2009, during the Great Recession, and another in 2010 — it’s certainly fast. 

The national debt exceeded $20 trillion in September 2017, after taking 20 months to add a trillion dollars. A debt limit that had been in place since March 2015 was raised in March 2017, and again on Sept. 8, 2017. 

Farther back, however, such trillion-dollar increases took longer: 43 months, for instance, near the end of Bill Clinton’s first term. 

The first time the nation’s debt hit $1 trillion was in October 1981, during Ronald Reagan’s first term. 

Looking ahead, analysts see the nation much deeper in debt. The Committee for a Responsible Budget projects trillion-dollar deficits returning permanently by next year, and debt exceeding the size of the economy within a decade.
