Another Bond Market Warning
Yield Are Rising. Should Stocks Fall?
History Suggests The Answer Is
More Nuanced
The 5% Test
The 10-year Treasury yield recently crossed the psychologically important 5% level, a threshold that many investors had been watching closely. After months of rising yields, there was growing concern that breaking through 5% could trigger another wave of bond selling and send yields sharply higher.
But that is not what happened. Yields briefly touched the level before pulling back, suggesting investors were still reluctant to push the cost of long-term money significantly above 5%, at least for now.
That leaves a more important question for markets: was 5% actually a ceiling, or merely a temporary pause before yields move even higher? The Fed Story Has Reversed
A year ago, markets were pricing for the Fed funds rate to fall toward 3% or below by mid-2027, assuming inflation would continue to cool and the Fed could gradually ease policy.
That expectation has now largely reversed. The policy rate is around 3.5%, but futures are pricing it back toward 4.5% by next summer.
Markets are no longer expecting a smooth path toward lower rates.

History suggests that when the Fed enters a genuine tightening cycle, long-term Treasury yields can continue rising well beyond the initial move. In previous cycles, the 10-year yield often climbed by more than 100 basis points after tightening began.
That creates a different possibility for today's market. The recent pullback from 5% could simply be a temporary correction rather than the end of the bond selloff.
Some historical analysis even
points toward the 10-year yield
reaching 6% before the Fed eventually finishes tightening. While that sounds extreme today, strong nominal economic growth can itself justify structurally higher yields. So, Will Stocks Fall?
This is where the relationship between rates and equities becomes less straightforward. Higher interest rates should pressure stocks by raising discount rates and making bonds relatively more attractive.
But historically, stocks have not necessarily collapsed when the Fed starts hiking. Most tightening cycles have taken place while nominal GDP was still growing, allowing economic growth and corporate earnings to provide some support for equities.
Across the previous six hiking cycles, the S&P 500 was almost invariably higher one year after the cycle began. The major exception was 2022, when the Fed was already significantly behind the inflation curve. The Real Risk Is 6%

The bigger concern is what happens if the 10-year Treasury does not simply revisit 5%, but moves rapidly toward 6%. That would take long-term borrowing costs to levels the market has not experienced this century.
The implications could be significant. Governments are carrying much higher debt loads after years of cheap financing, while companies and consumers have also become accustomed to relatively low borrowing costs.
For equities, the bigger problem may not be the level itself, but the speed of adjustment. If yields rise faster than earnings and economic growth can absorb, valuations could come under
meaningful pressure.
