The 10-year Treasury note spent the week grinding toward a round number nobody wanted to meet. The paper went to press Thursday night with it at 4.943% — the highest close since October 2023, and only the second time since the financial crisis that 5% has been this close. Friday morning the inflation report landed a tenth hot on core. The 10-year pushed to 4.975%. And stocks went up.
Two numbers, one report
Core inflation — everything except food and energy — rose 0.3% in August, above the 0.2% economists expected and up from July’s 0.2%. Fed governor Waller had said he’d be willing to hold at 0.2%. But the same report showed the annual core rate easing to 2.4% from 2.5%, and gasoline did more than a third of the month’s damage on its own, up 3.9% for the month. By Friday’s close West Texas crude had slipped 2.4% to $99.99, back under $100. Equities took the annual number and the cheaper barrel: the S&P 500 rose 0.86% to 7,656.98, the Dow 0.98%, the Nasdaq 0.96%, and the VIX fell 11% to 15.84.
The bond market read the monthly number instead. Traders now put a rate increase at next week’s Fed meeting near 80%, up from about 60% before the report, and price no cuts at all in 2026 at 94%. Treasury’s buyback couldn’t slow any of it: the government advertised up to $6 billion of long-dated purchases, three times its previous maximum, and bought only $5.2 billion, because it pays the market’s price like everybody else. The last time the 10-year crossed 4.9%, in 2023, a furious rally followed — but few expect the economy to cool quickly here, and a war with no end date keeps fuel expensive.
Where it reaches the kitchen table
This is the part that leaves the screen. The 10-year sets the price of mortgages, student loans and corporate debt; the 30-year fixed mortgage averaged 6.76% this week, up from 6.71%. Higher yields make a bond a better thing to buy and a worse thing to already own, and for most households the exposure isn’t a bond anyone picked — it’s the bond sleeve inside a target-date fund, carrying a duration nobody in the house ever chose.
The house rule hasn’t moved, which is rather the point of having one. The September letter said the tactical adds come back on three conditions: a core print of 0.1% or less, a Fed that holds, and vol-of-vol under 90. Core came in at 0.3%, a hike is roughly 80% priced, vol-of-vol sits at 91.3. Nothing new is being bought. A 4.975% yield isn’t a plan either — but the duration number off your bond fund’s fact sheet and the rate off your cash statement will tell you, in about fifteen minutes, which half of the safe money is actually doing its job.
