    Fiscal Consolidation Anchors Long Rates and Supports Equity Risk Premia

    HA·C:M
    Regime read

    Improving debt trajectories reduce the 'fiscal premium' in the 10Y yield (currently 5.11%). Lower debt-to-GDP expectations typically ease crowding out, supporting equities as the 2s10s curve (0.31) reflects a normalization of the term structure. This regime stabilizes financial conditions despite the current 3.88% effective funds rate.
