    Liquidity Contraction: Reserve Depletion Elevates Risk Premia and Term Spreads

    HA·C:H
    Regime read

    Contracting liquidity increases term premiums and risk spreads as central bank reserves exit the system. With the 10Y yield at 5.15% and HY spreads at a tight 3.29, the reversal of the portfolio balance effect pressures risky assets. This regime favors dollar strength and higher duration compensation as intermediary capacity tightens.
