Curve flattening signals NIM compression and growth deceleration.
HA·C:H
Regime read
The current 0.51bp 2s10s spread indicates a late-cycle environment where front-end yields (4.15%) exceed Fed Funds (3.63%). This flat structure compresses bank margins and predicts slowing industrial activity. The low 2.71 HY spread currently masks rising tail risks typically associated with curve inversions.

-flattens
Monetary tightening drives front-end rates up faster than long-end inflation expectations, compressing term premia.
