Nobody's boycotting Treasuries. They just want a raise.

The signal

On Oct. 7 the 10-year Treasury yield briefly topped 5.35%, its highest since 2002. Cue the obituaries for American credit. Then, that same afternoon, Treasury sold $39 billion of 10-year notes at 5.30% with a 2.77 bid-to-cover, and primary dealers, the designated adults who get stuck with whatever nobody else wants, took about 2.5% of competitive awards. At the December 2025 10-year auction they took 8.8% (our calculation from Treasury data). Some boycott.

Consensus says / signal says

Consensus says buyers are walking away from US debt: foreigners are leaving, the deficit is scary, everyone panic on schedule. Signal says the buyers showed up, ate everything on the plate, and sent back a bill. Indirect bidders (foreign official accounts, yes, but also plenty of domestic funds) took 80% of the 10-year. Meanwhile the 10-year inflation breakeven sat near 2.35% all week and the 10-year TIPS real yield near 2.9%. Translation: lenders are not terrified of inflation. They have simply noticed who they are lending to, and they have adjusted the price.

Why it matters

A price problem is less cinematic than a buyers' strike. It is also worse, because it never stops compounding. CBO's Oct. 8 review puts the FY2026 deficit at $1.993 trillion and net interest at $1.143 trillion, up 11% and roughly 21% of revenue, versus about 20% in FY2025. Ten-year money that cost 4.18% last December now costs 5.30%. Interest is now the line item nobody campaigns on and everybody pays.

And it arrives, with impeccable timing, three weeks before an election. Freddie Mac's 30-year mortgage average was 7.40% on Oct. 8, up from 6.30% a year earlier. On a $400,000 loan that is roughly $2,770 a month instead of $2,480 (our calculation). Pew finds 84% of registered voters call the economy very important to their vote. And the cavalry is not coming from the Fed: the September minutes show most officials expecting another hike by year end.

Into the midterms: three scenarios (hypotheses, not forecasts)

Mark your calendars, because Washington certainly has. The Fed meets Oct. 27-28. Voters go to the polls Nov. 3. On Nov. 4, the morning after, Treasury publishes its quarterly refunding plan, and its doubled long-bond buybacks quietly run out. Pure coincidence, surely.

1. The price holds through Election Day. Real yields near 2.9% keep mortgages above 7%, and housing costs stay on the ballot whether anyone printed them there or not. Nothing in this week's auction data forces anyone's hand.
2. The pre-vote sugar rush. The fastest levers belong to Treasury, not the Fed: stretch the bigger buybacks, or lean harder on short-term bills at the Nov. 4 refunding. Fed minutes say bill issuance has already risen sharply since July, so the habit is forming. It could shave long yields for a while. It also shortens the debt and raises rollover risk: a lower rate before the vote, financed by more rate exposure after it. The classic Washington trade, where the benefit is visible and the bill is postdated.
3. The morning-after repricing. Whoever wins, the refunding lands the next day. Divided government usually means gridlock: fewer new tax cuts, fewer new spending programs, and fiscal restraint achieved by nobody being able to agree on anything. A price-sensitive bond market might even reward that. Unified control, in either direction, widens room for deficit-financed promises before 2028, and lenders will charge accordingly.

Our hypothesis: the bond market will keep funding Washington through the election, just at a rate that keeps climbing until the fiscal path changes. Both parties spend; they just disagree about on what. The one lever that actually works is the one Congress controls, which is precisely why nobody is reaching for it.

What would change our mind

• November refunding auctions tail (clear above the pre-auction yield) with dealer awards back above roughly 10%. That would be genuine demand stress, and we would happily eat this headline.
• The 10-year breakeven climbs toward 2.6% or higher after September CPI (Oct. 14) while real yields fall. Then inflation, not the price of lending, becomes the story, and the campaign-trail argument shifts from borrowing costs to grocery receipts.
