International players and smaller insurance companies are expected to increase their investments in expanded-credit MBS.

Urban Institute researchers say the mortgage industry will experience slightly better capital treatment as a result of the changes to the Basel III Endgame, but they recommend some improvements.

The yield curve is helping to drive up demand for non-agency MBS. And rising delinquencies aren’t much of a concern for investors.

Investors aren’t tiering issuers/deals, fraud is a risk with cash-out DSCR mortgages, jumbos in expanded-credit MBS prepay faster than traditional expanded-credit mortgages and investors are getting aggressive with bids for GSE-eligible mortgages.

The rating service last week finalized a methodology update that will allow it to rate securitizations of home equity loans.

Excluding a one-off $5.69 billion issuance from Chase, securitization of home equity loans declined during the first quarter. Activity involving closed-end second liens held up while HELOC issuance fell. (Includes three data tables.)

Fitch placed a “deteriorating” outlook on the securitized second-lien market due to rising delinquencies. However, the rating service said that the sector is still performing within its base case expectations.
