What's behind the looming 'x-date' on the US debt limit?

White House chief of staff Jeff Zients, seen here in a Feb. 1, 2023 file photo, says President Biden wants to keep talks about government spending separate from a bill needed to raise the debt limit.

In January, the U.S. government ran up against its legal borrowing limit of $31.381 trillion, and the Treasury Department began implementing “extraordinary measures” to avoid missing payments on its bills.

That started speculation about the “x-date” — the date when those measures would be exhausted and the government might actually default if the limit on federal borrowing is not lifted. The x-date could be reached as early as June, depending on how much money the IRS collects in April from people filing their taxes.

HOW BIG A PROBLEM IS THIS?
