A money market fund looks like cash. It is not a bank account.
It lends for a short time, 6 months or less on average, to states and banks.
Its yield follows the ECB's rate closely: 2.50% since 16 September 2026, about €250 a year on €10,000 before fees.
When the ECB rate was −0.50% (2019 to 2022), these funds yielded less than zero.
And the €100,000 deposit guarantee does not cover them.
Where does your spare cash sit?
Education, not investment advice.
