Issuance of U.S. home-loan bonds without government backing more than tripled to $7.4 billion this year, according to a report from Deutsche Bank.

Notes sold in so-called non-agency securitizations of new loans, all of which were prime ‘jumbo’ mortgages, totaled $3.2 billion; sales tied to older mortgages reached $2.4 billion; and securities backed by non-performing debt were $1.8 billion.

Deutsche Bank analysts also wrote that new issuance of all non-agency securities next year should be a “few billion over $20 billion” when including potential deals involving rental homes.
