Why Can the 10-Year Treasury Yield Rise After a Fed Rate Cut?

01 · Rates and bonds

Why does a rate cut not send every interest rate lower?

On September 18, 2024, the Federal Reserve announced a 50-basis-point cut in its federal funds target range to 4.75%–5.00%. Lower rates might seem to imply higher bond prices. Yet by year-end the 10-year Treasury yield was above its level immediately before that cut. These observations concern different interest rates, so they need not contradict each other.

The policy rate primarily concerns overnight funding. A 10-year investor must consider uncertainty about rates and inflation over many years. One policy decision does not determine the direction of market yields at every maturity.

View policy decisions and Treasury observations together

This fixed official history runs from September 3 through December 31, 2024. From September 17, the day before the first cut, to year-end, the 10-year par yield rose from 3.65% to 4.58%, an increase of 0.93 percentage points. The 2-year yield rose from 3.59% to 4.25%, while the policy target upper bound fell from 5.50% to 4.50%.

The policy line shows the target upper bound as steps on effective dates. Event markers show FOMC announcement dates. Treasury lines are constant-maturity par yields, not the transaction price or investment return of one continuously held security. Daily observations alone cannot isolate the immediate announcement response or attribute the whole period to one rate cut.

Current policy and expectations over future years

The 2-year yield is generally sensitive to the expected policy path over the next few years. The 10-year yield reflects a longer expected path of short rates plus compensation for holding longer-term interest-rate risk. Revisions to growth, inflation or the expected extent of future easing can therefore accompany higher long yields after a current policy cut.

This is an analytical framework, not a unique explanation for every daily move. Funding conditions, bond supply, liquidity and risk appetite can also change. Two lines moving during the same period do not establish a single causal mechanism.

Term premium is estimated risk compensation

Term premium is the additional compensation investors require for exposure to interest-rate risk over a longer horizon. A higher premium can offset a lower expected path of short rates. It need not always be positive and is not a directly observed market quote.

The ACM model developed by New York Fed researchers estimates expected short rates and term premia from Treasury yields. Estimates depend on the model and data; they are neither direct transaction observations nor the FOMC’s official policy assessment. Here the model explains a concept, rather than assigning the entire change in the 10-year yield to term premium.

A yield change affects price, but price return is not total return

For a bond with fixed future cash flows, a higher required yield generally lowers present value. When other terms are comparable, bonds whose cash flows arrive later tend to be more sensitive. Duration helps summarize this price response, while repricing remaining cash flows gives the scenario’s actual modeled price.

A capital loss is only part of holding-period return. The investor may receive coupons, and the bond has a shorter remaining maturity at the end of the horizon. Reinvested coupons would add another component. Coupon terms, purchase prices and holding horizons can all change the ranking of short and long bonds.

Move from the market example to your own comparison

If you actually held bonds with different maturities, how much would their prices and holding-period returns differ? The companion comparison separates coupon contribution from price return and lets you change each exit YTM.

It uses hypothetical fixed-rate bonds. It does not turn the par-yield series above into a particular security’s historical performance. The case identifies the question; the comparison explores outcomes under explicit assumptions.
