Under 1% to 5% in Six Years: The 10-Year Treasury’s Wild Ride, and What to Do With a Yield Nobody Can Fully Explain
At the start of the decade the benchmark yield sat well under 1%. Last week it crossed 5% for the first time since 2007, and the new Fed chair can’t tell you which of two stories it’s telling. You can still build a plan that doesn’t need the answer.

Key Points
The 10-year Treasury yield rose above 5% last week for the first time since 2007, a 19-year high, and closed Friday at 4.995%; it dipped well below 1% at the start of the decade, the Journal reports. On Monday it eased to 4.96%, with the 2-year at 4.76% (Treasury.gov).
Steve Boothe of T. Rowe Price (TROW) calls it a double blow: pandemic and then war restricting supply and pushing inflation up, plus deficit-fueled demand. The annual deficit has hovered near $2 trillion, about 6% of GDP, a level once reserved for World War II and severe recessions.
The Fed raised rates last week for the first time since 2023, a quarter point to a 3.75%–4.00% target, and Chair Kevin Warsh said higher rates are needed again. The 10-year had hit a low just under 4% in late February — the day before the U.S. struck Iran.
Streetwise’s James Mackintosh: the 10-year began the year at 4.17%; 10-year breakeven inflation moved only from 2.25% to 2.33%, so most of the rise is real yield. Two Fed term-premium models disagree — Kim-Wright shows it up 0.4 point to the highest since just after 2008–09, ACM shows it lower this year.
The 200-day correlation between the S&P 500 and the 10-year yield is the most negative since 1997: stocks have been falling when yields rise. The Bloomberg long-Treasury index has returned −4.01% over 52 weeks at a 5.36% yield.

The benchmark that prices everything took six years to go from under 1% to 5%, and even the Fed’s own models can’t agree on why.
In one line: A 10-year near 5% is income you can lock by holding to maturity and a price risk for the long bonds you already own, and nobody — the Fed chair included — can be sure which story the yield is telling, so the plan shouldn’t need the answer.
Six years ago the 10-year Treasury yield sat well under 1%, and much of Wall Street had decided cheap money was the weather. Last week it crossed 5% for the first time since 2007 and closed Friday at 4.995%, the Journal reports; on Monday it eased to 4.96%, per Treasury.gov. The Journal spent a page on how the market got from one number to the other, and it’s worth the trip, because that one yield prices your mortgage, your CD and your annuity quote.
The short version is a run of bad breaks. Inflation surged in 2021 and then-Fed Chair Jerome Powell called it transitory, a word he’d retired by that November. In 2022 the Fed launched its most aggressive hiking campaign in decades and the S&P 500 fell 19%, its worst year since 2008. Silicon Valley Bank failed in early 2023 on its bond losses, but the recession everyone had positioned for didn’t come, and companies poured money into AI. Bigger-than-expected Treasury auctions pushed the 10-year to a brief 5% in October 2023. Trump’s 2024 win set off what Wall Street dubbed Trump trade 2.0, and tariffs and tax cuts have kept deficits and inflation elevated: the annual deficit has hovered near $2 trillion, about 6% of GDP, a level once reserved for World War II and severe recessions.
Two stories, one yield
The Fed cut gradually through 2025 and the 10-year hit a low just under 4% in late February. The next day the U.S. struck Iran, and the war has choked tanker traffic through the Strait of Hormuz and sent oil and inflation back up. Last week new Fed Chair Kevin Warsh delivered the first hike since 2023, a quarter point to 3.75%–4.00%. T. Rowe Price’s (TROW) Steve Boothe calls it a double blow of supply constraints and deficit-fueled demand: “I don’t think you can look at one without considering the other.” In Streetwise, James Mackintosh asks the harder question: is the yield up because the economy is strong, or because U.S. credibility is slipping? The measures don’t agree: breakevens barely moved, so most of the rise is real yield, and two Fed term-premium models point opposite ways. Warsh blamed a strong economy, AI-related bond issuance and the Gulf war; economists are also lifting neutral-rate estimates, a move Goldman Sachs (GS) called unexpectedly large; and columnist Andy Kessler argues tariffs shrink foreign buying of Treasurys and the fix is dropping them — his opinion, and a fourth story for the same yield.
Our read
Fixed Income (IN02): a 10-year near 5% is income you can lock by holding to maturity — Treasury ladders, brokered CDs and annuity payout rates all key off it — and a price risk for long bonds you already own; the Bloomberg long-Treasury index has returned −4.01% over 52 weeks, coupons included. The desk’s stance is hold: the reserve stays in T-bill and floating-rate funds (SGOV and USFR), with no long-duration adds. Treasury sells 2-, 5- and 7-year notes Tuesday through Thursday; that’s the week’s test.
The planning point is the correlation. The 200-day link between the S&P 500 and the 10-year yield is the most negative since 1997: stocks have tended to fall when bonds do, and that’s when a 60/40 mix diversifies less than the brochure promised. That’s why shorter duration and T-bills earn their place. Nobody, the Fed chair included, can be sure which story the yield is telling, so build the plan that doesn’t need the answer: match near-term spending to short paper and keep the long end a position you can afford to be wrong on. You don’t wait for the first drop to find the umbrella; fifteen minutes with your bond statement shows how much of it moves when the 10-year does.
What It Means For Your Portfolio
Hold — reserve in T-bills and floaters; no long-duration adds at 5%
The yield that prices everything went from under 1% to 5% in six years, and even the Fed’s own models can’t agree on why. A plan built to not need the answer is the kind most likely to survive the next chapter.
General planning principles, not advice for anyone in particular. A 10-year near 5% is a gift for the income side of a plan — Treasury ladders, brokered CDs and annuity payout rates all key off it — and a hazard for long bonds already held, whose prices fall when the yield rises. Match near-term spending to short paper, keep long duration modest, and treat TIPS as the inflation leg rather than a bet on the Fed; their prices still fall when real yields rise, and real yields did most of this year’s rising.
When stocks and bonds fall together, a 60/40 mix diversifies less than it once did, so the reserve should be the reserve: T-bills and floating-rate funds that don’t care which story the 10-year is telling. Nobody can be sure which one it is, so don’t build a plan that needs to know.
