CSSF Feedback Report - Thematic review - valuation framework for less liquid and illiquid assets

No description available.

AI Analysis

The CSSF has issued a feedback report on a thematic review of the **valuation framework for less liquid and illiquid assets**, signalling intensified supervisory focus on how Luxembourg investment fund managers value complex, hard‑to‑price positions. This matters because it will drive stricter expectations around valuation governance, model oversight, data validation, and the interaction between valuation, liquidity management, and investor protection for funds holding such assets. Although the specific 2026 feedback report text is not yet available, it clearly follows and deepens the CSSF’s 2023 Feedback Report on ESMA’s CSA on Valuation and its 2026 supervisory priorities on valuation, with a narrower focus on less liquid and illiquid assets.

Delay in the 2026 AML/CFT standardised data collection

AI Analysis

The CSSF circular letter dated 11 March 2026 announces a delay in its planned AML/CFT standardised data collection exercise originally scheduled for 2026, primarily due to overlap with a concurrent broad-scope data collection by the European Anti-Money Laundering Authority (AMLA). This matters for compliance professionals as it reduces immediate reporting burdens on supervised entities, promotes regulatory simplification, and aligns Luxembourg practices with emerging EU AML/CFT methodologies, allowing firms to redirect resources to the mandatory AMLA exercise.
