What are the restrictions applied to UCITS Funds?

UCITS (Undertakings for Collective Investment in Transferable Securities) funds are among the most widely recognised and trusted investment fund structures globally. Designed to provide a high level of investor protection, transparency and liquidity, UCITS funds appeal to both retail and institutional investors and benefit from a robust, harmonised regulatory framework across the European Union. Compliance with the UCITS Directive is achieved through a series of core rules, five of which are outlined below.

1. Eligible investments

UCITS funds are intended to invest primarily in liquid, transferable and well-understood (“plain vanilla”) financial instruments. Eligible assets include listed equities and bonds, money market instruments, bank deposits, units in other UCITS funds and certain financial derivatives. Investments must generally be traded on regulated markets or meet defined liquidity and valuation criteria. This focus on liquidity and transparency is central to the UCITS framework and helps ensure that funds can meet redemption requests in a timely manner.

2. Portfolio concentration and diversification

UCITS funds are subject to strict diversification limits designed to mitigate concentration risk. As a general rule, a UCITS fund may not invest more than 10% of its net asset value (NAV) in transferable securities or money market instruments issued by the same issuer. In addition, the aggregate value of positions that exceed 5% of NAV may not represent more than 40% of the fund’s portfolio (the so-called “5/10/40 rule”). Certain derogations apply for government and supranational issuers, index-tracking funds and other specific strategies. These rules ensure that UCITS portfolios remain diversified and resilient.

3. Leverage and global exposure

UCITS funds may use derivatives for investment, hedging or efficient portfolio management purposes, subject to limits on global exposure. Two methodologies are permitted. Under the Commitment Approach, derivative exposure is converted into equivalent positions in the underlying assets and is limited to 100% of NAV. Alternatively, funds with more complex strategies may use a Value at Risk (VaR) approach. Under the Relative VaR model, a fund’s VaR may not exceed twice that of a comparable reference portfolio, while under the Absolute VaR model, VaR is capped at 20% of NAV. Robust risk management systems and detailed disclosure are required under both approaches.

4. Borrowing restrictions

Borrowing by UCITS funds is tightly controlled. A UCITS may borrow up to 10% of NAV on a temporary basis, typically to manage short-term liquidity needs rather than to generate leverage. Permanent or structural borrowing is not permitted, reinforcing the conservative risk profile of UCITS products.

5. Liquidity and dealing frequency

Liquidity is a defining feature of UCITS funds. Most UCITS offer daily dealing and redemption, with NAVs calculated and published on each dealing day. At a minimum, UCITS funds must provide investors with at least two dealing days per month at regular intervals. Importantly, the liquidity terms offered to investors must be consistent with the liquidity profile of the underlying assets, and liquidity risk management is a key focus of regulatory oversight.
