Issuance of non-agency MBS last year topped the volume seen pre-pandemic. Activity was concentrated on prime loans, both non-agency jumbos and GSE-eligible mortgages. (Includes data chart.)

Mortgages in the transaction were acquired by Western Alliance Bank on a correspondent basis and will remain on its balance sheet. Risk-sharing deals in the non-agency market are rare and largely involve megabanks.
