    Secular Stagnation Gravity vs. Cyclical Rate Peaks

    HA·C:M
    Regime read

    Stable demographics exert structural downward pressure on real yields and equity multiples as the population ages. While DGS10 at 5.24% reflects cyclical inflation (CPI 3.72%), the long-term r* remains anchored by life-cycle savings behavior. Expect secular growth headwinds to eventually counteract the current high-rate environment.
