Issuance of non-agency MBS backed by newly originated mortgages increased by 34.2% on a quarterly basis in the first quarter of 2026. (Includes data tables.)

Weakness in the housing market last year did not materially impact non-qualified mortgage delinquency rates, according to research by Goldman Sachs.
