A Hawkish Fed Chair Repriced the Entire Easing Path
Markets entered the year expecting a gradual cutting cycle. The new chair prioritized returning inflation to target, and Treasury yields stayed elevated through the first half as a result.
The Expectation Going In
Markets began 2026 positioned for a continued easing cycle. Inflation had come down substantially from its peak, growth was steady, and the prevailing assumption was that policy would normalize gradually toward a neutral setting.
That assumption was embedded in a great deal more than rate futures. It sat inside equity valuations through the discount rate, inside bond duration positioning, and inside the case for zero yielding assets like gold.
What Changed
The new chair adopted a noticeably more hawkish tone than markets had anticipated, emphasizing that returning inflation to target took precedence over supporting growth. The practical implication was that rates could stay higher for longer than the easing path investors had priced.
Treasury yields remained elevated through much of the first half as that repricing worked through. Nothing about the economy had deteriorated. The reaction function, meaning how the central bank was expected to respond to a given set of data, had changed.
The data did not move. The rule for translating data into policy did, and that was enough to reprice everything built on top of it.
Reaction Function, Explained
The concept worth learning here is the reaction function. Markets do not simply forecast the economy. They forecast how policymakers will respond to the economy, and then price assets against that expected response.
This is why a change in leadership can move markets without any change in conditions. Two chairs facing identical inflation and employment data may weigh the mandates differently, tolerate different amounts of labor market softening, and place different weight on the risk of easing too early.
An investor holding a long duration bond is not only betting on inflation. They are betting on how a specific committee will respond to inflation, which is a judgment about people as much as about economics.
Why Credibility Costs Less Than It Looks
There is a defensible argument for the hawkish posture, and it is worth stating fairly. A central bank that eases prematurely and then has to reverse loses credibility, and credibility is the cheapest tool it has.
When inflation expectations are anchored, the bank can achieve outcomes with words and modest moves. When they become unanchored, it requires far higher rates and a genuine recession to restore them, which is the lesson of the 1970s that every modern committee has studied.
Erring hawkish sacrifices some growth in exchange for protecting an asset that is expensive to rebuild. Whether that trade is correct depends on how close expectations actually were to slipping, which is not directly observable.
What It Did to Asset Prices
Elevated yields raise the discount rate applied to future cash flows, which weighs most on assets whose value sits furthest in the future. That is the mechanism behind the rotation seen through the first half, away from the longest duration growth names.
It also raised the opportunity cost of holding assets that generate no income, contributing to the correction in precious metals after their January peak. Different assets, one underlying driver.
The Bottom Line
A change in leadership repriced markets without any change in the economy, because prices reflect an expected policy response rather than conditions alone. Knowing the reaction function matters as much as knowing the data.
