The conspiracy theory that Trump is crashing the economy to bring down interest rates to refinance the national debt is complete nonsense!
The U.S. is currently paying an average interest rate of about 3.3% on its $36 trillion national debt. That’s already lower than where market rates are today (the 10-year Treasury is yielding around 4% and the 30-year is closer to 4.4%).
So for this plan to even begin to make sense, interest rates would need to plunge well below current levels, down to 2% or 3%.
And even if that happened, it wouldn’t be some game-changing win. Yes, over time, some of the debt matures and gets rolled over.
Refinancing that portion at lower rates (3% instead of 5%) could help around the edges.
But you can’t just call up America’s creditors and refinance the entire $36 trillion like it’s a mortgage.
That’s not how any of this works. Most of the national debt is in short-term Treasury bills and notes that are constantly rolling over.
Even if rates fall, you’d still be refinancing gradually, over time, as debt matures, not in one big bang.
And you definitely can’t shift all that short-term debt into 30-year bonds. The demand just isn’t there.
Long-term Treasuries (those maturing in 20 to 30 years) make up only about 17% of the total market. Try cramming trillions into that, and you’d blow up the bond market.
Right now, Treasury bills (which mature in less than a year) make up about 22% of U.S. debt. Treasury notes (2–10 year maturities) make up around 51%.
Each part of the bond market has its own supply and demand dynamics. Bills are basically cash-like instruments; they don’t have interest rate risk and their prices barely move. That’s a big reason there’s always strong demand for them.
You can’t simply shift a huge chunk of short-term debt into long-term bonds.
Those carry a lot of interest rate risk, and the pool of buyers is different (mostly pension funds and insurance companies).
If the Treasury tried to flood the market with long-term bonds, demand might not keep up, which would actually push long-term rates even higher.
We’re already seeing some of that. Despite rising recession fears, 30-year bond yields haven’t dropped much, suggesting limited demand at those durations.
Now, at the margins, the Treasury can and does tweak the debt mix…maybe shifting a little from bills to notes, or notes to bonds.
But it’s a balancing act, not something you can radically change overnight.
