Transaction structure and collateral profile
As reported by KBRA, citing Kroll Bond Rating Agency, Sierra Residential DAC is a static RMBS securitisation backed predominantly by first-lien, reperforming mortgage loans in Spain. The underlying collateral consists mainly of owner-occupied residential properties, which account for 95.3% of the pool, while the remaining 4.7% is secured by second or holiday homes and non-residential properties.About 64.7% of the portfolio has previously been restructured. The loans were originated by Banco Santander, S.A. and other financial institutions later absorbed by or merged with Santander, which remains the lender of record and the primary servicer.
The mortgage loans are securitised through mortgage transfer certificates, or CTHs, issued by Santander and held by FT Cazorla, a Spanish private securitisation fund. That fund is managed by Intermoney Titulización, S.G.F.T., S.A., while the issuer holds the corresponding unitranche FT Cazorla Bonds.
Servicing setup and note protections
Intrum Servicing Spain, S.A.U. acts as special servicer for loans that are more than 35 days in arrears, adding a dedicated workout layer for weaker-performing exposures in the pool. The servicing arrangement reflects the reperforming nature of the collateral and the need for closer management of delinquent loans.The notes follow a sequential principal payment priority under a combined collections waterfall. A funded liquidity reserve supports senior expenses and interest payments on the Class A notes, providing an additional layer of protection for the most senior tranche.
In our earlier coverage of the IMF’s October outlook for Europe, we highlighted that the region’s recovery remains fragmented, with improving prospects in Germany and the UK, relative strength in Spain, and continued weakness in France. We also noted how persistent inflation risks, tight fiscal constraints, and competitiveness gaps are shaping credit sentiment and borrowing conditions across European markets.
