Fragile Complacency: Compressed Spreads and Low Volatility Invite Mean Reversion Risk.
HA·C:M
Regime read
Market complacency is extreme, with HY OAS at 2.8% and the VIX at 14.21 suggesting significant mispricing of tail risks. The 10Y yield at 5.18% creates a high hurdle for equities, making current sentiment vulnerable to rapid reversals. Transmission will likely occur via a volatility spike and flight-to-safety into Treasuries as equity-bond correlations turn negative.
