Structural Growth Headwinds as Dependency Ratios Stabilize at Higher Levels
HA·C:M
Regime read
Stable but aging demographics exert downward pressure on r*, contradicting the current 5.22% 10Y yield. While a 4.2% unemployment rate suggests labor tightness, the structural decline in working-age population growth limits long-run potential GDP. Asset valuations face a decumulation headwind as the peak-earning cohort transitions to retirement spending.
