From Constraint to Catalyst: How Solvency II Reform Reprices Securitization for European Insurers

This note is the first in a short series exploring how the upcoming Solvency II reform may reshape insurer capital and the opportunity set across European credit markets.

Key Takeaways:

• High-Grade Asset-Based Finance Can Become Core: The recalibration of spread risk charges, particularly for senior tranches of securitizations, is set to improve the capital efficiency of structured credit assets such as high-grade asset-based finance (ABF) for European insurers. While U.S. insurers have benefited from more efficient capital treatment of these assets, the revised framework will enable European insurers to more meaningfully incorporate high-grade ABF alongside investment-grade corporates in portfolio construction, with the potential for enhanced spread per unit of regulatory capital.
• Capital Efficiency is Improving Where it Matters: The revised framework would enhance insurers’ ability to deploy capital into longer-duration, high quality private assets with treatment more closely aligned to the underlying risk. For CIOs and CROs, this should expand the opportunity set of asset allocation but will still require disciplined asset liability management and underwriting of illiquidity and complexity.
• A Structural Step Toward Unlocking European Capital Markets: The reforms reflect a thoughtful and measured recalibration that reduces regulatory capital inefficiency while preserving prudential safeguards. This could enable European insurers to play a larger role in the capital needs of more constituents of the European economy, at a time of heightened need for the type of patient, long-term financing at scale that the banking sector is not inherently designed to provide.   

Solvency II: Where the Real Change is Happening

In October 2025, the European Commission finalized long-anticipated amendments to Solvency II, with implementation expected by January 2027. While presented as a technical recalibration of capital rules, the reform is more consequential than it may first appear — repricing regulatory capital and reshaping relative value across asset classes. At its core, the reform is designed to remove structural barriers that have limited insurers’ ability to deploy capital into long-term investments, particularly in areas such as securitization and equity, while supporting broader EU priorities around growth and competitiveness.

While the review spans multiple areas, the most immediate and actionable impact is the expected recalibration of capital charges for securitizations. In our view, this change has the potential to fundamentally reshape insurer participation in high-grade ABF, while supporting the broader development of European capital markets and facilitating the flow of capital into the economy.

This aligns closely with a theme we highlighted in The Power of Credit, Europe remains a “heavy demand, light supply” market, where structural demand for duration and structured credit assets is robust, but regulatory costs have historically constrained origination and insurer participation. Solvency II reform begins to address that imbalance.

Securitization: Leaning into Regulatory Efficiency

One of the most significant shifts within the revised framework is the expected recalibration of spread risk charges for securitizations.

Historically, Solvency II imposed comparatively high capital charges on securitized exposures, particularly non-STS (Simple, Transparent and Standardized) transactions, which limited insurer participation and as a result reduced the role of structured credit within standard formula portfolios.

That is now due to change.

The revised framework would improve treatment across both STS and non-STS assets, with the most notable benefits applied to senior non-STS tranches. Importantly the clearer distinction between senior and non-senior exposures means higher quality senior tranches are no longer treated the same as riskier subordinated exposures.

We believe the magnitude of this change is meaningful. As illustrated in exhibit 1, capital charges for investment-grade securitizations with 1–5 year duration would decline depending on tranche and structure. In parallel, exhibit 2 shows how the revised framework could improve the regulatory efficiency of European CLOs and high-grade ABF. Under current rules, an illustrative 3-year non-STS securitized portfolio carries a spread risk SCR approximately 46%. Under the revised framework, that would fall to approximately 22%.

In practical terms, insurers could access wider spreads in senior, high-quality securitization tranches with a capital treatment more proportionate to underlying risk. This would bring ABF, CLOs, and other securitized exposures into play with EUR investment-grade corporates in portfolio construction.

Put simply: high-grade ABF and CLOs would look more attractive on a capital adjusted basis.

Why This Matters: The Importance of High-Grade ABF

The implications should be immediate, with high-grade securitizations standing out. Historically, capital treatment, not credit quality, was the limiting factor. Under the revised framework, that will change. As a result, insurers may increasingly view investing in high-grade ABF as a core component of private investment grade portfolios complementing public corporate credit and offering incremental spread with comparable credit quality.

A similar dynamic will apply to senior CLO tranches, where improved capital treatment would enhance their return on capital. More broadly, recalibration supports the EU’s Savings and Investment Union agenda by lowering structural barriers to securitized lending, ultimately facilitating funding for SMEs, infrastructure, and real-economy investment. Beyond this area, the review includes refinements to long-term equity treatment, risk calibration, volatility adjustment, and interest rate shocks reflecting the experience of recent market environments.

Taken together, these changes will improve overall capital flexibility and expand the opportunity available to insurers. While the impact will vary by insurer, we believe the direction is clear and encouraging: a more proportionate and practical framework that is aligned with real-world asset allocation.

Solvency II Reform: A Structural, Not Cyclical, Shift

Solvency II reform is best understood as a structural evolution rather than a cyclical easing — a measured adjustment that modernizes the framework while preserving its core intent.

In doing so, the reform supports greater allocation to longer-duration and high-quality assets that underpin economic growth (i.e. infrastructure and project finance) within disciplined architecture. As implementation nears, early alignment across governance, risk management, and portfolio strategy will matter even more than tactical repositioning in our view.

As we have noted, the market’s constraint has been supply, not demand. Solvency II reform represents an important step in that direction, helping match structural demand with actionable supply.
