Valuation Pressures in Luxembourg’s Private Markets: Getting It Right in a Higher-Rate Environment

Higher discount rates are compressing valuations, particularly for long-duration and asset-heavy strategies, such as infrastructure and real estate, where large upfront investment and long payback periods make valuations highly sensitive to changes in interest rates. Refinancing costs are weighing on portfolio company earnings, while thin transaction volumes make it harder to source comparables. Infrequent appraisals risk producing stale marks that diverge from secondary pricing and in evergreen or hybrid structures common in Luxembourg, redemption demands can collide with valuation lags. These dynamics put NAV credibility under pressure at precisely the time investors and regulators are demanding more rigour.

Luxembourg’s position as Europe’s leading domicile for private debt and alternative fund structures means the stakes are high. Both ESMA and the CSSF have highlighted weaknesses in governance and independence of valuation functions, highlighting that valuations are no longer a technical back-office process but a frontline test of credibility.

Regulators are sharpening their focus on valuations. ESMA has confirmed that valuation will remain a supervisory priority in 2026, with work under way on harmonised benchmarks, stronger stress testing and safeguards against conflicts of interest. In Luxembourg, the CSSF’s feedback on the 2025 Common Supervisory Action required IFMs to reassess frameworks, particularly governance, independence and control of assumptions. Spot checks and closer scrutiny of valuation committees are expected to follow, alongside a possible revision of Circular 18/698.

The UK’s FCA has already highlighted weaknesses around valuation independence and procedures during stressed markets. For Luxembourg managers with UK investors, these developments provide a clear indication of regulatory direction that may influence EU practice.

Luxembourg-domiciled funds face recurring challenges in valuation, especially in volatile conditions. Methodology inconsistencies across jurisdictions or fund lines can raise questions when LPs compare results across structures. Independence is another sensitive area: valuation teams that sit too close to portfolio management risk conflicts of interest, a concern repeatedly raised by the CSSF. Illiquidity compounds the difficulty, with stale marks and lagged appraisals leaving NAVs vulnerable to sharp corrections. Finally, weak documentation and data comparability can undermine both investor confidence and regulatory defence, particularly in cross-border portfolios.

1. Governance and independence: Establish independent valuation committees, involve external experts where appropriate and maintain strict firewalls between valuation and portfolio management.
2. Clear methodology: Define and document valuation policies covering assumptions, revaluation triggers and adjustment protocols. Apply frameworks consistently across funds, drawing on IPEV and IOSCO guidelines where relevant.
3. Stress testing and scenarios: Supplement base valuations with downside scenarios and sensitivity tables. Back-test prior valuations against realised exits to calibrate assumptions.
4. Timely monitoring: Be prepared to conduct interim valuations during stress events such as rate shocks or widening spreads. Avoid reliance on outdated “carry valuations.”
5. Transparency and audit trail: Provide investors with clear disclosures on assumptions, adjustments and conflicts of interest. Maintain robust systems with versioning, audit logs and explanatory memos for subjective judgments.

Luxembourg’s scale and sophistication make it the natural hub for private funds in Europe, but this visibility also attracts greater scrutiny. Any weakness in valuation practices can create reputational ripple effects well beyond a single vehicle. For managers, the opportunity lies in treating valuation frameworks not merely as a compliance obligation but as a differentiator that enhances investor confidence.

In today’s higher-rate, lower-liquidity environment, valuations will be examined with increasing precision. Strong governance, rigorous documentation and transparent communication are essential, not only to satisfy regulators but also to build lasting trust with investors.
