A New Fed Chair Is Announced — Every Instance Since 1951
S&P 500 forward paths from all nine chair-nomination announcements, overlaid
Every presidential announcement of a NEW Federal Reserve chair since the 1951 Treasury-Fed Accord, overlaid on one chart: Martin 1951, Burns 1969, Miller 1977, Volcker 1979, Greenspan 1987, Bernanke 2005, Yellen 2013, Powell 2017, and Warsh in January 2026. Each line is the S&P 500's path over the following trading year, indexed to 100 at the announcement. Renominations of sitting chairs are excluded — this chart isolates genuine leadership changes.
What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
A new Fed chair is one of the rarest recurring macro events — rarer than recessions. Each announcement resets the market's expectations for the entire policy reaction function.
Across all nine transitions the median forward path drifts higher over the following year, but the dispersion is enormous: Greenspan's first year contained the 1987 crash, while Burns' first year rolled into the 1970 bear market.
The macro backdrop the new chair inherits dominates the path. Volcker inherited runaway inflation; Bernanke inherited a housing bubble. The announcement tells you the referee changed, not how the game goes.
The highlighted path shows the market since the January 2026 Warsh announcement against all eight prior transitions — a live historical analog you can track week by week.
A chair transition is a reason to review duration and rate-sensitive positioning, not to de-risk equities. History says the first year after an announcement is usually unremarkable for the index — the dispersion came from the macro hand the new chair was dealt. If your plan only works under one policy regime, fix the plan, not the allocation date.
