Answer: Owners of deposits in savings accounts have a direct repayment claim on their bank.
Holders of UCITS fund units own a proportionate claim on the underlying assets of the fund. They therefore have a claim on numerous financial enterprises, companies and/or, as the case may be, countries, municipalities and institutions.
The value of each fund depends on the underlying assets, i.e. the financial strength of the issuer of the assets in which the fund has invested and, as the case may be, any guarantees that individual issuers have provided. The position and fate of the financial enterprises that manage UCITS thus does not directly impact the value of UCITS funds, as their balance sheet is separate from that of the financial enterprise.
