Curve Flattening Signal: NIM Compression and Growth Deceleration Ahead
HA·C:H
Regime read
The T10Y2Y spread at 0.33 indicates a maturing hiking cycle where the DFF of 3.88% pressures short-term funding. Empirical evidence suggests this flattening regime compresses bank margins and precedes widening HY OAS (currently 3.29). A strong USD (DTWEXBGS 121.4) and high WTI (101.91) further tighten conditions, increasing recession risks.
