What it means for your shop

The 181 bps mortgage–10Y spread leaves origination margins compressed; a flattening curve typically narrows that spread further, so any steepening relief is temporary—operators should watch whether the 10Y holds above 4.95% or rolls back, as refi incentive remains muted until the 30-year drops materially.
