Flat Curve Signals Late-Cycle Margin Compression and Growth Deceleration
HA·C:H
Regime read
A flat curve (2s10s at 0.44) typically signals the transition from restrictive policy to growth slowing. With DGS10 at 5.22 and HY spreads tight at 3.15, the market is pricing a 'soft landing' despite the flattening. However, empirical evidence suggests persistent flattening will compress bank NIMs and eventually lead to credit tightening.
