Here's who pays. By Paul Haull. 6-minute read. | | Good morning. Yesterday the U.S. government had to promise lenders more for 30 years of its money than at any point since 2002\. Most headlines call that "turmoil in the bond market." I call it a repricing, and every repricing has a side that pays and a side that collects. Let's find out which side you're on. | | What happened **The long bond:** on Tuesday the 30-year Treasury yield touched about 5.6%, its highest since 2002\. The 10-year topped 5.29% during the session, its highest since 2007. **The damage:** Treasuries have lost 2.6% so far this year, by Bloomberg's count. "Safe" bonds are down while their yields climb. **The reasons:** oil kept high by a seven-month Middle East war, inflation well above the Fed's 2% target, a Fed that started raising rates this month, and a flood of new government and corporate borrowing. **This morning:** the Fed's preferred inflation gauge came in cooler than expected. Prices rose 3.4% from a year earlier in August, down from 3.7%. Short-term yields fell on the news.

A bond is a fixed promise: so many dollars a year, then your money back at the end. The promise doesn't change. What changes is what the market demands for new promises. When new bonds pay 6%, nobody will pay full price for your old bond paying 5%. Its price drops until the math evens out. Yields up, prices down. Always. And the longer the promise, the harder the drop. Here's how hard, for a single one-point rise in rates. | | ![Chart: when yields rise from 5% to 6%, a 2-year bond loses 1.9%, a 10-year loses 7.4%, a 30-year loses 13.8%](https://storage.ghost.io/c/57/e4/57e45f93-ee6d-484b-b06b-a5c3b2063579/content/images/2026/09/rates1-bond-loss.png) **How to read this:** each bar is the paper loss on a bond paying 5% when new bonds start paying 6%. Same promise, same issuer. The only difference is how many years you're locked in. | | Put it in dollars. $100,000 in 30-year bonds bought at 5% would show roughly $13,800 less on your statement after that one-point move. Nobody defaulted. Nothing was missed. The market simply moved the line, and the people who lent yesterday paid for it. | | Paul's rule When new lenders demand more, the old lenders pay for it. | | 2 of 3 Why lenders suddenly want more A lender asks two questions: will I be paid back, and what will the money be worth when I am? Right now the second question is doing the damage. With oil elevated and inflation running well above target, a 30-year promise in dollars looks riskier than it did a year ago. At the same time Washington keeps borrowing heavily, and so do corporations. More IOUs chasing the same pool of lenders means each borrower has to pay up. That's why this morning's inflation report mattered so much. Read the document, not the headline. | | The Fine Print The Commerce Department's August report on personal consumption prices, released at 8:30 this morning, shows prices up **3.4%** from a year earlier, down from 3.7% in July. The core measure, which strips out food and energy, rose **3.0%**, down from 3.3%. Both came in cooler than Wall Street expected. The two-year yield fell to about 4.83%, and traders cut the odds of another Fed hike in October to roughly one in three. Notice what didn't change: 3.4% is still well above the Fed's 2% target. One cooler month is relief, not a reversal.

If you're a saver with cash to put to work, the side going up is yours. For most of the past fifteen years, safe government bonds paid close to inflation or less. Look at the gap today. | | ![Chart: 2-year Treasury 4.83%, 10-year 5.24%, 30-year 5.56%, all above August inflation of 3.4%](https://storage.ghost.io/c/57/e4/57e45f93-ee6d-484b-b06b-a5c3b2063579/content/images/2026/09/rates2-yields-vs-inflation.png) **How to read this:** the gap between each bar and the dashed line is your real return, what you earn after inflation. Right now it runs from about 1.4 to 2.2 points a year. | | Borrowers sit on the losing end. Freddie Mac's 30-year mortgage rate hit 7.03% last week, above 7% for the first time since January 2025\. A year ago it was 6.30%. | | Worked example: a $300,000 mortgage A year ago, at 6.30%$1,857 a month Today, at 7.03%$2,002 a month **Extra cost**$1,740 a year Principal and interest only, 30-year fixed. Taxes and insurance not included. | | And the biggest borrower of all is Washington. Every new dollar it borrows now costs more, and that bill lands on taxpayers for decades. Same seesaw, much bigger plank. | | Test yourself: who moved up the line? A rate shock sorts people fast. Find yourself below. Front of the line Savers with cash ready to lend at today's rates Retirees buying new bonds, CDs or Treasury bills Anyone holding short-term bonds that mature soon and can be reinvested higher Back of the line Holders of long-term bonds and bond funds bought when rates were low Home buyers and anyone who needs to borrow Taxpayers, who carry Washington's rising interest bill | | The Protocol Four moves to make this week 1**Look up the "duration" of every bond fund you own.** It's on the fund's fact sheet. Rough rule: a duration of 6 means about a 6% drop for each one-point rise in rates. Now you know your exposure in one number. 2**Know whether you own bonds or a bond fund.** An individual Treasury held to maturity pays back its full face value, whatever its price did along the way. A fund never matures, so its price keeps floating. 3**Build a ladder instead of guessing the top.** Split new money across maturities, say one to five years. Each year one rung comes due and you reinvest at whatever rates are on offer then. 4**Run the 7% math before any housing decision.** Downsizing, buying a second place, or helping a child with a down payment: price it at today's rate, not last year's. | | Liquidation Value: locking in 5.6% for 30 years A long bond looks like a sure thing. Here's what it really costs to own one. **Price swings.** If rates rise another point, a 30-year bond can show a loss of about 14% on paper. **Inflation.** The payment is fixed. If inflation averages above your yield, you lose buying power every year. **Time.** Thirty years is a long lock-up at 64\. Shorter maturities keep your options open. **Taxes.** Treasury interest is taxed federally but exempt from state and local income tax. **I'm wrong if** inflation falls fast and rates drop. Then long bonds win, and short-term savers reinvest at lower rates. | | The Boardroom A question I get a lot: should I wait for rates to go higher? Nobody rings a bell at the top. On Tuesday the long bond hit a 24-year high. By this morning, a single cooler inflation report had already pulled short-term yields down. That's how fast the window moves. So don't try to pick the day. Pick a schedule. Put part of your money to work now and add more over the coming months. If rates keep rising, your next purchase buys higher. If they fall, you've already locked some in. Either way, you're never all wrong. | | That's it for this morning. Next time you read a rate headline, skip what it means for Wall Street and ask one question: which end of the seesaw am I sitting on? Paul Haull |
