US National Debt Tops $38.7 Trillion as Government Borrowing Accelerates

The US national debt hit $38.749 trillion on February 20th, climbing 7% over the past year — the fastest pace since the pandemic spending surge. That’s roughly $5.4 billion added in just one day, a rate that would push total debt past $40 trillion before year-end.

This acceleration comes as the government faces twin pressures: higher interest costs on existing debt and expanded spending from recent government shutdowns creating snapback effects. With the 10-year Treasury yielding over 4%, every new dollar borrowed costs significantly more than the ultra-low rates of the 2010s. Meanwhile, corporate America is sitting on historically fat profit margins and investing heavily in AI and productivity — creating a stark contrast between public sector borrowing and private sector capital allocation.

The debt trajectory matters enormously for bond markets and the dollar’s global reserve status. When debt grows faster than the economy (current GDP is around $29 trillion), investors start questioning sustainability. Historically, debt-to-GDP ratios above 130% — where we’re heading — have coincided with either fiscal reforms or currency debasements. Many professional investors are watching whether continued US productivity gains from AI investment can outgrow the debt burden, or whether we’re approaching a point where debt service crowds out other spending.

Bottom Line: The government is borrowing at Depression-era speeds during an economic expansion — a combination that historically doesn’t end well without serious productivity gains to outgrow the debt.
