If Federal Reserve Chair Jay Powell were to step down or be removed—particularly under politically contentious circumstances—the impact across U.S. Treasury markets could be swift and multifaceted. Market reactions would likely be driven by rising concerns about central bank independence, uncertainty around future monetary policy, and the risk of increased political influence over interest rate decisions.
Historically, U.S. Treasury yields have responded sharply to leadership transitions at the Federal Reserve. Following Powell’s nomination in November 2017, the 10-year yield rose by nearly 30 basis points over the following month, reflecting expectations for continued policy normalization. Similarly, Janet Yellen’s nomination in 2013 corresponded with a modest increase in yields, though much of that was also driven by anticipation of Fed tapering.
However, the context of Powell’s potential departure matters significantly. A politically charged exit could lead to a steepening of the yield curve, with short-end rates falling on expectations of easier monetary policy and longer-dated yields rising on concerns about inflation credibility and rising risk premiums.
Treasury Yield Curve Reaction
The immediate response in yields would likely be a bear steepening of the curve. Front-end yields (2-year) could fall by 10 to 25 basis points on expectations of a more dovish successor or greater political influence over monetary policy. Meanwhile, long-end yields (10- and 30-year) could rise by 15 to 40 basis points, driven by a re-pricing of term premia and inflation expectations. This could push the 2s/10s spread, currently near +55 basis points, toward +70 to +90 basis points in a matter of days, with steeper moves if Powell’s departure is perceived as a threat to Fed independence.
During periods of leadership uncertainty or politicization of the Fed—such as President Trump’s 2018 public criticisms—markets briefly feared rate policy interference. At the time, the 10-year yield dropped from 3.2% to 2.9% in a flight-to-safety move, but the current environment, characterized by a large fiscal deficit, persistent inflationary pressure, and tariff risks, may push long-end yields in the opposite direction.
Breakeven Inflation Rates and TIPS Demand
Expectations for long-term inflation, reflected in breakeven rates, would likely jump. The 10-year breakeven inflation rate, which sits around 2.41%, could rise toward 2.65% or higher, as markets anticipate looser monetary policy or diminished resolve to keep inflation in check. Similarly, 5-year breakevens, currently at 2.49%, could spike to 2.75%, driven by concerns that Fed leadership could prioritize political pressure over inflation targeting.
This shift would also accelerate inflows into Treasury Inflation-Protected Securities (TIPS), with potential outflows from nominal long-duration Treasuries, pressuring real yields upward. One could expect a 10 to 15 basis points drop in TIPS yields alongside rising nominal yields, particularly if risk sentiment deteriorates.
MOVE Index and Volatility Expectations
The Merrill Option Volatility Estimate (MOVE) Index, a key gauge of Treasury market volatility, is a primary barometer of market stress. Currently hovering near 90, a Powell departure could push it sharply higher, potentially toward the 140–160 range, in line with spikes observed during major systemic stress events (e.g., March 2023 regional bank turmoil, the March 2020 COVID shock, or more recently “Liberation Day” on April 2). A sustained breach above 140 would reflect deep investor unease over policy continuity and signal elevated hedging activity in the rates market.
Liquidity, Auction Dynamics, and Term Premium
The term premium—a measure of the excess yield investors demand to hold long-term bonds—would likely rise. The current 10-year term premium is hovering close to 0.5%, based on the latest data from the Federal Reserve Bank of St. Louis. In a credibility crisis, it could increase by 20 to 30 basis points, making longer-dated Treasuries less attractive and worsening auction demand, especially from foreign buyers who place a premium on Fed stability.
This would manifest in weaker bid-to-cover ratios at Treasury auctions, rising tail risk (the spread between the auction yield and pre-auction market yield), and more pronounced intraday yield swings in the on-the-run Treasury complex.
Overall, a Powell departure—especially under duress—would inject meaningful turbulence into fixed income markets, not only repricing duration risk but also threatening the institutional scaffolding that underpins market trust in monetary policy. Markets would look closely at the Fed’s response, the identity of any successor, and the tone of upcoming FOMC communications to reassess the inflation outlook and recalibrate risk exposure.
