KBRA has released preliminary ratings for seven classes of notes issued by the GS Mortgage‑Backed Securities Trust 2026‑CES3 (GSMBS 2026‑CES3), a $354.2 million residential mortgage‑backed securities (RMBS) transaction sponsored by Goldman Sachs Mortgage Company. The rating provides early insight into the credit profile of a deal composed entirely of closed‑end second‑lien mortgages.
KBRA Assigns Preliminary Ratings to GS Mortgage‑Backed Securities Trust 2026‑CES3
KBRA assigned preliminary ratings to all seven note classes of the GSMBS 2026‑CES3 transaction. The RMBS pool consists of 3,803 loans, seasoned roughly six months, with AmeriSave Mortgage Corporation contributing 41.0% of the originations. The underlying mortgages are fully amortizing fixed‑rate loans, with term distribution of 2.6% (10‑year), 5.6% (15‑year), 27.8% (20‑year), 1.5% (25‑year) and 62.4% (30‑year). The rating report and supporting documents are available through KBRA’s website.
Deal Structure and Underlying Collateral
The GSMBS 2026‑CES3 structure incorporates excess spread and a sequential interest‑and‑principal waterfall. Loss allocation follows a reverse‑sequential order, beginning with the Class B‑3 notes and proceeding to the Class A‑1 notes. All collateral is classified as closed‑end second‑lien mortgages (CES), representing 100% of the pool. The transaction’s size of $354.2 million and its fully amortizing, fixed‑rate composition are intended to provide predictable cash flows for investors.
Implications for Financial Institutions
Preliminary ratings give banks, insurers, and other institutional investors an early gauge of credit risk before the final rating is issued. The reverse‑sequential loss allocation may affect the relative risk exposure of different tranches, a factor that portfolio managers will consider when allocating capital to the various note classes. The concentration of originations with AmeriSave Mortgage Corporation (41.0%) may also be a focus of credit monitoring.
Key Takeaways
