    Liquidity Contraction: Duration Pressure and Intermediary Deleveraging

    HA·C:H
    Regime read

    Contracting liquidity drives term premia higher while straining risk-asset valuations. With WTI at $96.41 and DGS10 at 5.18%, the economy faces a dual shock of high input costs and tightening financial conditions. Intermediary balance sheet constraints will likely widen HY spreads from the current 2.8% level as reserves drain.
