Treasury Secretary Janet Yellen
Treasury Secretary Janet Yellen warned congressional leaders of both parties on Tuesday that lawmakers have until Oct. 18 to raise or suspend the debt limit before the United States is expected to default on the national debt.
"At that point, we expect the Treasury would be left with very limited resources that would be depleted quickly. It is uncertain whether we could continue to meet all the nation's commitments after that date."
While Yellen called the date the agency's "best estimate" as of now, she noted:
"the federal government's cash flows are subject to unavoidable variability. For example, the government's daily gross cash flow (excluding financing) over the past year averages nearly $50 billion per day and has exceeded $300 billion. As a result, it is important to remember that estimates regarding how long our remaining extraordinary measures and cash may last can unpredictably shift forward or backward."
That uncertainty, the former Federal Reserve chairwoman said, underscores the "critical importance of not waiting to raise or suspend the debt limit."

Yellen sent identical letters to Speaker Nancy Pelosi (D-Calif.), House Minority Leader Kevin McCarthy (R-Calif.), Senate Majority Leader Charles Schumer (D-N.Y.) and Senate Minority Leader Mitch McConnell (R-Ky.).

In recent days, Democrats have sought to tackle the debt limit via a continuing resolution to fund the government ahead of a Thursday deadline to avert a shutdown.

The legislation passed last week in the House, where Democrats hold a razor-thin majority. It failed in the evenly split Senate on Monday evening however, after Republicans followed through on their threat to block the legislation in opposition to Democrats' trillion-dollar spending plans.

McConnell has been urging Republicans to vote against raising the debt ceiling amid a high-stakes standoff with Democrats, as frustrations stew over a $3.5 trillion social safety net package the party aims to pass using reconciliation, a procedure that will allow them to bypass the Senate GOP filibuster.

Republicans have called on Democrats to address the debt limit using that same process, though there are disagreements between party leaders over how much time the maneuver could take ahead of the looming deadline.

Democrats have tried to insist Republicans work with them to raise or suspend the debt limit, pointing to the multiple instances both parties did so under previous administrations.

In her letter on Tuesday, Yellen sought to put pressure on lawmakers to act with haste to resolve the matter, warning of the dangers of waiting until the eleventh hour. She wrote:
"We know from previous debt limit impasses that waiting until the last minute can cause serious harm to business and consumer confidence, raise borrowing costs for taxpayers, and negatively impact the credit rating of the United States for years to come.

"Failure to act promptly could also result in substantial disruptions to financial markets, as heightened uncertainty can exacerbate volatility and erode investor confidence."
