National Debt Hits $39 Trillion, Up $2.77 Trillion in 12 Months
Total public debt reached $38.98 trillion as of April 3, a 7.6% increase from $36.2 trillion a year ago. The government's average borrowing cost continues to climb as cheap pandemic-era debt rolls over.

What Happened
Total U.S. public debt stood at $38.982 trillion as of April 3, 2026. One year ago, it was $36.214 trillion -- an increase of $2.77 trillion, or 7.6%.
Debt held by the public, the portion that matters most for interest costs, is $31.409 trillion. Intragovernmental holdings (money the government owes itself, primarily Social Security trust funds) account for the remaining $7.572 trillion.
The quarter-end figure on March 31 was slightly higher at $39.065 trillion, with the dip into early April reflecting maturity rollovers and intragovernmental rebalancing.
The Cost of Carrying It
| Security Type | Avg Rate (Mar 2026) | Avg Rate (Feb 2026) | Change |
|---|---|---|---|
| Treasury Bills | 3.702% | 3.720% | -0.018 |
| Treasury Notes | 3.212% | 3.190% | +0.022 |
| Treasury Bonds | 3.392% | 3.377% | +0.015 |
| TIPS | 0.999% | 0.990% | +0.009 |
| Floating Rate Notes | 3.628% | 3.748% | -0.120 |
| Total Interest-Bearing | 3.327% | 3.320% |
The blended average interest rate on all federal debt is 3.327% as of March 2026, up from 3.316% in January. This slow grind higher reflects the core problem: pandemic-era debt issued at near-zero rates is maturing and being refinanced at current rates above 3.5%.
At $38.98 trillion and 3.327%, the annualized gross interest cost is approximately $1.3 trillion.
March Auction Selloff
The Treasury market saw a sharp move in March. Note yields jumped significantly from February auctions:
| Term | Feb Yield | Mar Yield | Change |
|---|---|---|---|
| 2-Year | 3.455% | 3.936% | +48.1 bps |
| 5-Year | 3.615% | 3.980% | +36.5 bps |
| 7-Year | 3.790% | 4.255% | +46.5 bps |
| 10-Year | -- | 4.217% | -- |
| 20-Year | 4.664% | 4.817% | +15.3 bps |
| 30-Year | -- | 4.871% | -- |
The 2-year yield jumped nearly half a percentage point in a single month. Bid-to-cover ratios remained solid (2.29-2.55x), meaning buyers are still showing up -- they just demand higher yields.
The Yield Curve
| Maturity | Yield (Apr 3) |
|---|---|
| 1 Month | 3.71% |
| 3 Month | 3.71% |
| 6 Month | 3.73% |
| 1 Year | 3.72% |
| 2 Year | 3.84% |
| 5 Year | 3.99% |
| 10 Year | 4.35% |
| 20 Year | 4.91% |
| 30 Year | 4.91% |
The curve is normally shaped and steepening. The 2s10s spread is +51 basis points. One notable feature: the 20-year and 30-year are both at 4.91%, an unusually flat long end that suggests the market sees minimal additional duration risk beyond 20 years.
What It Means
The federal government is borrowing at a pace of roughly $7.6 billion per day. The interest cost alone -- $1.3 trillion annualized -- now exceeds the defense budget. Each basis point increase in the average rate adds approximately $3.9 billion in annual interest expense.
The March auction selloff, with 2-year yields jumping 48 basis points, signals that markets are repricing rate expectations. With the Fed paused at 3.64% and inflation at 2.43%, the front end of the curve may have gotten ahead of itself on rate cuts that are not materializing.
The solid bid-to-cover ratios are the silver lining: demand for Treasuries remains robust even at higher yields. The risk is not a failed auction -- it is the slow, compounding cost of rolling over $39 trillion in debt at rates that keep climbing.
