Kevin Warsh appeared before senators on April 21 for his confirmation hearing as nominee for Federal Reserve chair, bringing renewed attention to a recurring debate: whether the arrival of a new Fed chief reliably produces financial market shocks. A broad historical review suggests the answer is not straightforward.
Deutsche Bank examined swings in the S&P 500 relative to 52-week highs around Fed Chair transitions dating back to 1925 and concluded the record is mixed. Analysts at the bank observed that there are many instances in which a change in leadership did not coincide with pronounced market declines.
At the same time, there are clear examples where severe turbulence occurred soon after a new chair took office. The most prominent of these is the Black Monday crash of 1987, which hit about two months into Alan Greenspan's tenure.
Other early-tenure stress episodes had varying contexts. Arthur Burns assumed the chairmanship in February 1970 and stepped into an economy already contracting, meaning the recession predated his swearing-in. In Paul Volcker's case, his forceful tightening of monetary policy did usher in a recession; Deutsche Bank notes that confronting high inflation was the explicit objective of Volcker's appointment, framing that episode more as a deliberate policy shift than a market test of a new leader.
Transitions in more recent decades have seen longer lags between a change in Fed leadership and the emergence of major financial disturbances. Under Ben Bernanke, the first signs of the 2007-2009 crisis appeared roughly 18 months after he took office, with the collapse of Lehman Brothers occurring about 2.5 years into his term. Deutsche Bank's review similarly shows that under Jerome Powell the COVID-19 shock struck about two years into his tenure.
Should Warsh be confirmed, Deutsche Bank flagged three areas that could exert pressure on markets and complicate his confirmation path. These are his earlier public support for lowering interest rates, his articulated positions on the independence of the Federal Reserve, and his preference for a smaller Fed balance sheet. The analysts emphasized that those views may clash with current market expectations that the United States does not require rate cuts.
The confirmation process may also be delayed by political maneuvering tied to an ongoing Department of Justice investigation of Chair Jerome Powell. Republican Senator Thom Tillis has said he will block all Fed nominations while that investigation remains active, which would prevent Warsh's nomination from moving out of the Senate Banking Committee to a full Senate vote.
Powell has addressed his status in public meetings. At the March Federal Open Market Committee session he said he would serve as Chair Pro Tempore until a successor is confirmed and indicated he plans to remain on the Board of Governors until the DoJ inquiry concludes, stating, "I have no intention of leaving the board until the investigation is well and truly over, with transparency and finality."
Deutsche Bank also pointed to the political calculations surrounding timing, suggesting it may be convenient for different parties to allow a confirmation delay while geopolitical uncertainties continue. The bank wrote, "It’s possible this delay suits all parties for now while the uncertainties of the war rumble on."
Key points
- Historical record of Fed Chair transitions shows mixed outcomes for markets, with some rapid crises and other episodes where stress arrived much later or not directly linked to leadership change - impacts felt across equity markets and financial services.
- Specific early crises under new chairs include Black Monday in 1987 shortly after Alan Greenspan took office; Paul Volcker's tightening precipitated a recession but was aimed at reducing inflation - implications for interest-rate-sensitive sectors such as banking and consumer discretionary.
- Current nomination risks include policy stances and political obstacles that could delay confirmation and affect market expectations for interest rate paths and balance sheet policy - relevant to fixed income, bank stocks, and Treasury markets.
Risks and uncertainties
- Political blocking of Fed nominations while the DoJ investigation of Chair Powell is active could stall Warsh's confirmation, leaving leadership uncertainty at the Fed - risk for policy continuity and markets dependent on clear rate guidance.
- Warsh's previously stated support for rate cuts, his views on Fed independence, and a preference for a smaller balance sheet may clash with prevailing market assumptions that rate cuts are unnecessary, creating policy-market mismatches that could pressure interest-rate-sensitive sectors.
- Timing of macro shocks relative to chair transitions is inconsistent historically; major market stress has in some cases occurred well after a new chair's appointment, adding uncertainty about when and how shocks might materialize and complicating planning for investors and corporates.
