The Treasury Puzzle: Why Long Bonds Are Selling Off Into a Rate Cut

A divergence in the yield curve reveals competing forces that matter more than Fed policy alone

With the Federal Reserve all but certain to deliver its third consecutive quarter-point rate cut this Wednesday, you might expect Treasury prices to rally and yields to fall. Instead, long-dated Treasury's are selling off sharply, pushing yields higher and leaving bond ETF investors scratching their heads.

The iShares 20+ Year Treasury Bond ETF (TLT) dropped to a three-month low this week, even as futures markets price in an 89% probability of that anticipated cut. The 30-year Treasury yield climbed to nearly 4.81%, up meaningfully from October's lows around 4.5%. Meanwhile, the benchmark 10-year yield rose to 4.17%, its highest level since September.

A Tale of Two Markets

The answer lies in understanding that different parts of the yield curve respond to different forces.

Short-term yields remain tightly anchored to Fed policy. The 2-year Treasury is hovering around 3.58%, slightly below the effective fed funds rate and largely unchanged in recent weeks. This is textbook behavior: when the Fed signals cuts, the front end of the curve listens.

The 30-year bond, however, operates on its own terms. It's the least tethered to whatever Jerome Powell says on Wednesday. Instead, larger fiscal deficits and shifting inflation expectations are driving the action. The U.S. government's borrowing needs aren't shrinking, and investors demanding compensation for holding debt over three decades are repricing risk accordingly.

There's also a global dimension worth noting. Japan has become an aggressive competitor for long-dated investors, offering yields that haven't been this attractive in years. If you're in the market for 30-year sovereign debt, both the U.S. and Japan are now competing for your capital and both face similar fiscal challenges. This isn't necessarily alarming, but it does mean the U.S. Treasury can't take buyer demand for granted.

Where the Opportunity Has Been

Not all duration has been created equal this year.

The sweet spot has been intermediate-term bonds. The iShares 7–10 Year Treasury Bond ETF (IEF) is up 7.8% year-to-date, outpacing both TLT and the shorter-duration iShares 1–3 Year Treasury Bond ETF (SHY), which has gained 4.5%.

Why the outperformance? Intermediate maturities captured the rate-driven gains earlier in the year when expectations for Fed easing ramped up, while largely sidestepping the sharpest pain in the recent long-bond selloff. The 10-year bottomed near 4% before climbing to current levels, elevated but still well below January's highs near 4.8%.

Monday's auction results offered a glimmer of encouragement for bulls: the Treasury's 3-year note sale came in strong, stopping at 3.61%, below both the recent average and the pre-auction yield. Demand at the front end remains healthy.

What to Watch Wednesday

Traders will parse every word from Powell's press conference and scrutinize the Fed's updated dot plot projections. The rate cut itself is largely priced in the real question is how many additional cuts officials pencil in for 2025 and beyond.

For long-bond investors, however, the more important signals may come from fiscal policy debates and inflation data in the months ahead. The Fed can cut rates, but it can't single-handedly compress term premiums or shrink budget deficits.

The Bottom Line

Rising long-dated yields heading into a rate cut isn't the contradiction it appears to be. It reflects a market grappling with competing pressures: accommodative monetary policy on one hand, persistent fiscal concerns and global competition for capital on the other.

For retail investors, the takeaway is straightforward. Duration positioning matters. Those who stayed in the intermediate part of the curve have been rewarded this year. And while the Fed remains the dominant force at the front end, the long bond increasingly answers to different masters.
