The Justice Department's April 2026 closure of its criminal probe into Fed Chair Jerome Powell—centered on alleged false statements regarding $2.5 billion headquarters renovation cost overruns—remains the dominant driver of market-implied odds. Prosecutors found no evidence of criminality, a federal judge quashed subpoenas citing “essentially zero evidence,” and the matter was referred to the Fed’s inspector general, with U.S. Attorney Jeanine Pirro noting only a remote possibility of reopening. This outcome followed months of political tension over monetary policy independence, rate decisions, and executive pressure, factors that had briefly weighed on Treasury yields and equity sentiment earlier in the year. With Powell’s chairmanship concluded and no subsequent filings or revived grand jury activity through mid-August 2026, trader consensus reflects a near-certain view that federal charges will not materialize, though any unexpected IG findings could serve as a low-probability catalyst.
