What that means for the bond side of your portfolio

On September 23 the 10-year Treasury yield closed above 5.1% for the first time since 2007. If you own bonds, they have moved in price this year, up or down depending on their maturity. For most maturities the price change is the small part. A new 10-year Treasury pays more than it has in almost two decades, short Treasuries pay what they paid in 2023, and the yield is the story.

Why yields rose

The 10-year started 2026 at 4.19%. Since then Brent crude has climbed back above $100 a barrel, gasoline rose almost 4% in August alone, and inflation is running at 3.4%. The Fed raised rates in September for the first time since 2023, by a unanimous vote, and most of its officials expect at least one more hike before year-end. Business surveys show activity running at its fastest pace in five years. A strong economy with stubborn inflation and a Fed leaning against it pushes yields up. That is what happened.

What rising yields did to bond prices

When yields rise, existing bond prices fall, and how far they fall depends on how long the bond has to run. This year a fund holding 7-to-10-year Treasuries is down about 4%, price and interest combined. A fund holding 3-to-7-year Treasuries is down about 2.5%. A fund holding 1-to-3-year Treasuries is about flat. The shorter the bonds, the less a one-point rise in rates has mattered, and bond portfolios built for stability usually sit toward the shorter end of that range.

The reason is the income. A bond yielding 4% has paid you about 3% of your money over the last nine months, and for a short bond that payment more than covered the price change. Compare 2021, when short-term Treasuries yielded well under 1%. There was almost no income to absorb the price moves of 2022, so even a short Treasury fund dipped about 6% before recovering, and long Treasuries lost nearly half their value. Low starting yields made 2022 a bad year. High starting yields are why 2026 has been an ordinary one.

The same arithmetic applies from here. A short-term bond fund yielding about 4.5% with a duration of two to three years has close to two full points of cushion: rates would have to rise that much over the next twelve months before the price decline caught up with the income. In 2021 the cushion was a fraction of a point. That is the difference between owning bonds at 1% and owning them at 4% to 5%.

What it means in dollars

Say you are retired and put $1,000,000 into a ladder of 1-to-5-year Treasuries. A ladder built at the end of 2021 yielded under 1% and paid roughly $9,000 a year. The same ladder built today yields about 4.75% and pays about $47,000. Same dollars, same maturities, five times the income.

That shows up in three places:

• Your withdrawals. A retiree taking 4% a year from a balanced portfolio used to need the stocks to do almost all the work. At today’s yields the bonds in that portfolio cover close to half the check on their own, up from about a tenth in 2021, which means fewer shares sold in a down year.
• Every other investment you are offered. A 5-year Treasury pays 5.0% today, backed by the U.S. government. A rental netting 6% after repairs and vacancies, a private deal promising 8% with a five-year lockup, a dividend stock yielding 3.5%: all of them have to be measured against that 5%, and all of them looked better when the alternative paid 1%.
• Your cash. Treasury bills pay about 4%. Six figures sitting in a checking account earning nothing costs you real money again.

Two mistakes to avoid

The first is reaching for the biggest number. A 30-year Treasury pays 5.4% today against 5.0% for a 5-year, and it moves roughly three times as much when rates change. The near-50% drawdown in long bonds a few years ago happened to people who wanted an extra point of yield. Short and intermediate maturities capture most of the yield with a fraction of the price swings.

The second is waiting for 6%. Yields might get there. They might also turn around next month if oil falls or the economy cools. A 5-year Treasury bought today and held to maturity pays 5.0% no matter what yields do next. Buying it and then watching yields go to 6% is a fine outcome. Sitting in cash waiting for 6% and watching yields fall back to 4% is the one that stings.

Why you own bonds

For most of the years since 2008 the case for bonds was insurance. They have usually held their value when stocks fell, and that is worth something even when they pay nothing. That was true, and it was a hard thing to be happy about.

But the amount of bonds you own was never a bet on interest rates. It came out of your plan. Somewhere in that plan is a number for what you spend each year, a number for how many years of that spending should sit in something that does not move with the stock market, and a decision about how much of a drop you could live through without selling at the bottom. Those three things set your bond allocation. The yield on the 10-year had almost nothing to do with it.

That is why the allocation was not built around 2021, when bonds paid 1% and holding them felt like a chore, and why it does not need rebuilding now that they pay 5% and holding them feels smart. The job was the same both years: cover the next several years of withdrawals, and keep you from having to sell stocks in a bad year. Short bonds did that job in 2022, when they were down a few percent while stocks were down nearly twenty. That is the job they are there to do in the next bad year.

What is different now is the pay. The insurance is the same, and today it pays 4% to 5% while you hold it. Bonds did not learn a new trick this year. They went back to paying you.

Bond fund yields are yields to maturity and are not guaranteed; bond prices fall when interest rates rise, and longer-maturity bonds fall more. Treasury securities are backed by the U.S. government as to timely payment of principal and interest if held to maturity; sold before maturity they may be worth more or less than their original cost.
