What Is a RAIF?
A RAIF (Reserved Alternative Investment Fund) is a Luxembourg investment fund vehicle that does not require direct authorisation by the CSSF — instead it is regulated indirectly through its authorised Alternative Investment Fund Manager (AIFM). This significantly reduces time to market compared to CSSF-authorised structures like the SIF, while still providing EU distribution passporting through the AIFMD framework. RAIFs were introduced under the Luxembourg RAIF Law of 23 July 2016.
Overview
How a RAIF Works
Before the RAIF was introduced, alternative fund managers wanting a Luxembourg-domiciled fund vehicle typically used the Specialised Investment Fund (SIF), which required direct CSSF authorisation — a process that could take several months. The RAIF eliminates this delay by removing the CSSF authorisation requirement for the fund itself. Instead, the RAIF must be managed by a fully authorised AIFM under the AIFMD, which is already CSSF-supervised. The regulatory oversight of the AIFM substitutes for direct fund authorisation.
The RAIF can invest in any asset class — private equity, real estate, infrastructure, hedge strategies, private debt, fund of funds — without investment restrictions. It is restricted to well-informed investors (institutional investors and investors committing a minimum of EUR 125,000, or those with written assessment from a regulated institution confirming their expertise). It cannot be distributed to retail investors.
The RAIF benefits from EU AIFMD passporting through its authorised AIFM, allowing distribution to professional investors across the EU without requiring separate national registrations. This makes it an attractive alternative to offshore structures for European fund distribution mandates.

Use Cases
When a RAIF Is Used
Private Equity and Venture Capital
RAIFs are widely used by PE and VC managers wanting a Luxembourg-domiciled fund with EU passporting. The fast time to market — typically weeks rather than months — makes them attractive for managers with time-sensitive fundraising needs.
Real Estate Funds
Luxembourg RAIFs are commonly used for European real estate investment strategies, benefiting from Luxembourg's participation exemption on dividends from real estate holding companies and EU distribution passporting.
Parallel Fund Structures
Many managers run parallel Cayman and Luxembourg fund structures to serve US and non-EU investors (Cayman) and EU investors (RAIF) from the same strategy. The RAIF provides the EU vehicle without the SIF delay.
Infrastructure and Private Debt
RAIFs are used for infrastructure and private debt strategies where EU institutional investor distribution is important and the AIFMD framework is required for regulatory compliance by insurance companies and pension funds investing in the fund.
