Rabobank FX strategist Jane Foley described the current environment as one where markets are actively questioning the credibility of both the Federal Reserve under Warsh and the Treasury under Bessent, noting unusual pressure on the dollar alongside the bond market stress seen this week. Credibility concerns of this nature are typically associated with periods of policy inconsistency or perceived political interference in central bank operations.
For Armada's traditional desk, credibility erosion at the Fed and Treasury has direct pass-through to repo market conditions. MMF counterparties become more selective about term exposure, primary dealers widen spreads on Treasury collateral repo, and SOFR itself can become volatile if the Fed's forward guidance loses anchor. This is also a Basel III and G-SIB concern: if bank balance sheets tighten in response to sovereign risk repricing, SLR-constrained dealers pull back from intermediation, reducing repo market liquidity.
