What it would mean

If this plays out, it is a risk-off shock. A spike in interest-rate volatility widens agency-MBS spreads and crushes mortgage-REIT book values, forcing deleveraging and dividend cuts; the rate-vol shock de-rates the mortgage-REIT cohort and tightens housing credit. The trigger decomposes into signed root‑shocks — Credit spreads ▲ · Mortgage rates ▲ · Risk appetite ▼ — which propagate through our causal graph to the markets below.
