The Fed Chair Turnover "Curse"

In nearly a century of the Federal Reserve's monetary policy history, the "turnover curse" is not unfounded. According to historical modeling analysis by institutions like Barclays, since 1930, the S&P 500 index has typically experienced an average 16% significant pullback within six months of a new chairman taking office. This volatility essentially serves as a "stress test" of the global capital markets' response to the new leader's policy boundaries, communication style, and anti-inflation resolve.
Historical Market Records During Each Chairman's Early Term
Paul Volcker (August 1979)
Within three months of taking office, the S&P 500 experienced a maximum drawdown of about 10.2%. Volcker immediately demonstrated an extreme "tough stance" style, combating runaway inflation through aggressive rate hikes and controlling the money supply, leading to a sharp liquidity crunch and market upheaval in the short term.
Alan Greenspan (August 1987)
Within two months of taking office, the market experienced an epic 33.5% crash. Greenspan assumed office less than two months before the 1987 "Black Monday," which became the most severe confidence test faced by a new chairman in history.
Ben Bernanke (February 2006)
Within four months of taking office, the index retreated about 12.0%. At that time, there was a misunderstanding of Bernanke's "inflation targeting" approach, with concerns that the Fed might over-tighten amid economic slowdown, triggering a sharp revision of expectations.
Janet Yellen (February 2014)
Within eight months of taking office, the decline was approximately 7.4%. Yellen's transition was relatively smooth, but as the quantitative easing (QE) policy was formally phased out, the market experienced significant turbulence in October of that year due to the "taper tantrum" tail effect.
Jerome Powell (February 2018)
Within ten months of taking office, the S&P 500 experienced a maximum drawdown of 19.8%. Powell's early hawkish stance on balance sheet reduction led to accelerated liquidity tightening, ultimately triggering a deep correction approaching a technical bear market in Q4 2018.
This "turnover pullback" phenomenon mainly stems from two logical points: first, the cost of establishing credibility—new chairs often need to adopt a hawkish stance early on to build anti-inflation credibility; second, expectation reshaping friction—markets need time to digest the communication style unique to each new leader.
As Kevin Warsh is expected to officially succeed around mid-May 2026, and given his "hawkish" policy inclination toward the balance sheet, historical data suggests that investors should be prepared for the market to repeat this "initial dip followed by rebound" volatility pattern over the next six months. While maintaining a long-term core position in the market, vigilance is required for short-term shocks caused by liquidity re-pricing.
