The bond market is rejecting Washington's fiscal recklessness, and the bill is landing squarely on your mortgage payment.

Treasury Secretary Scott Bessent announced last week that the government would sharply ramp up purchases of treasury bonds to push down yields — effectively the interest rate Washington pays on its $40 trillion mountain of debt. It didn't work. Yields dipped briefly, then bounced right back. By Friday, the 10-year yield was near where it started and the 30-year was trading around its highest level in 20 years.

Here's what that means for you: mortgage rates on 30-year home loans have climbed from about 6% to 6.75% since the start of the year, according to The New Yorker. Car loans, credit cards — anything tied to long-term borrowing costs — moves in lockstep with treasury yields. The housing market is freezing up, and the pinch is being felt on every kitchen table in the country.

The root cause is simple. The federal debt has ballooned to a record $40 trillion. Interest payments this year will absorb 13.5% of all federal spending — more than defense — up from 5.2% in 2021, The Guardian reports. That's your tax dollars servicing debt instead of building roads or securing the border. Every dollar that goes to bondholders is a dollar that doesn't go to Americans.

And the buyers propping up this market are changing in ways that should worry everyone. Foreign central banks — mainly China and Japan — have sharply pared back their holdings. The foreign share of treasuries has fallen roughly 10 percentage points over the past two decades, down to about 40%. Private foreign investors have picked up some slack, holding $7 trillion in treasuries by mid-2025 compared to $3.9 trillion held by foreign official entities. But private investors chase returns, not stability. They sell when the math turns. The Guardian framed this shift as a threat to the "global economy" and the end of America's safe-haven status. What they buried: the real threat is to the American worker who funds this whole arrangement.

President Trump has called interest rates "ridiculous" and "artificially high" and blamed the Federal Reserve. He lashed out at Switzerland for having lower rates and hinted that "the ultimate intervention is our military." The New Yorker, for its part, framed the story around Bessent's history as a young hedge-fund manager working for George Soros during the 1992 pound crisis — when Soros's team bet against the British currency and netted a billion dollars while the Bank of England was humiliated. The implication is that Bessent should know better than to tangle with markets. Fair enough. But the deeper story isn't about one man's biography — it's about a structural problem both parties created.

Bessent's own stated job, as he put it in a November speech, is "to serve as the primary caretaker of the Treasury market." But you can't be the caretaker of a market you're flooding with IOUs. Since late March, the 10-year yield has risen from 4.32% to 4.73% and the 30-year from 4.9% to 5.28%. The consensus in the markets, The New Yorker reports, is that Bessent is unlikely to accomplish his goal — and that his intervention could backfire if it undermines faith in the creditworthiness of the U.S. government.

That's the open question: what happens when the world stops believing that American debt is risk-free? Not some abstract geopolitical puzzle — the question is whether you can still afford the house you're trying to buy.
