Commercial Mortgage-Backed Securities
2025 was the strongest year for European CMBS issuance since the pre-GFC era: €8.7 bn across 17 transactions, against only €2.2 bn (5 deals) in 2024. Issuance in 2025 alone exceeded the previous three years combined.
What CMBS is
A CMBS is a securitisation in which one or more commercial real-estate loans — single-loan, pan-European pool or conduit — are transferred into an SPV that issues rated, tranched notes to institutional investors. The originator keeps 5% vertical or horizontal risk retention under the EU / UK Securitisation Regulation; the rest moves off balance sheet. Servicing is performed by a specialist master / special servicer, with control-valuation events and cash-trap mechanics driving post-issuance governance.
Market snapshot 2025 / 2026
Weighted-average note margins tightened to their tightest levels in four years. 2026 opened with the first European CMBS of the year already in the market. Ratings agencies (Scope, S&P, KBRA) describe the sector outlook as cautiously positive for logistics / industrial and multifamily, neutral for retail, and negative for offices — where refinancing stress is concentrated.
Deutsche Bank, Goldman Sachs, Morgan Stanley and Bank of America remain the dominant book-runners in Europe; sponsors include Blackstone, Starwood, EQT Real Estate and Brookfield.
Why CMBS is back
Three forces have re-opened the European CMBS window:
Pricing arbitrage. Post-2023 spread compression in AAA / AA tranches, combined with bank RWA cost under CRR3, makes securitised distribution economic again.
Investor appetite. ABS / RMBS accounts (e.g., Aegon AM, Bracebridge, Cheyne) have CRE allocations that they were unable to deploy in 2021–2023. The rebuilding of dedicated CRE ABS desks follows.
Balance-sheet necessity. The large CRE refinancings coming through 2025–2027 cannot all be held on bank balance sheets under CRR3. CMBS is the distribution end of the stack; see Regulatory.
Legal and structural themes for practitioners
Risk retention and STS. CMBS remains generally outside the EU STS regime; retention is usually by the originator, occasionally by a third-party sponsor (original-lender route). The interaction with the CRR3 output floor — whether retained tranches are treated in line with the standardised or IRB calculation — is a live topic for 2026 pipeline transactions.
Operating-advisor / controlling-class mechanics. Control-valuation events, appraisal reductions and B-piece transfer restrictions drive most post-closing disputes. The European market has largely aligned on U.S.-style controlling-class mechanics, but national insolvency overlays remain decisive.
Servicing standard. The U.S. “servicing standard” has largely been imported into EU deals; enforcement regimes (Germany, Spain, Italy, the Netherlands) remain materially different, shaping expected recovery timelines and the pricing of the B-piece.
ESG / Article 9 overlays. Green-labelled CMBS tranches are increasingly demanded by EU institutional buyers; CRR3 does not yet formally reward them, but SFDR reporting expectations and Taxonomy alignment are tightening. See Regulatory · Taxonomy.
