Invest in money market funds, without any constraints
Our EUR and USD money market funds give you direct access to performance by removing the hurdles of a securities account and multi-portal management. Enjoy a unique solution to maximise your returns while reducing your risks. All from a single, unified platform.
A flexible and high-performing investment for your surplus cash
Competitive rate of return
Maximise the yield on your surplus cash:
- For your EUR: The yield on our MMF is correlated to the €STR. As of 16 March 2026, the yield stands at 1.65%.
- For your USD: The yield on our MMF is correlated to the Federal Funds Rate. As of 16 March 2026, this yield stands at 3.46%.

No maximum balance
Access to the fund is very flexible: the minimum initial subscription is €/$ 1,000, and €/$ 1 for subsequent ones. You can invest your surplus cash with no amount limit.
Very low risk on your capital
Depending on the currency, the fund is primarily invested in Eurozone government debt (EUR MMF) or U.S. Treasury bills (USD MMF), both of which are renowned for their high quality and stability. Therefore, while the invested capital is not guaranteed, the risk of loss is very low.
Centralised and integrated management
No more need to open a securities account or juggle multiple financial portals to grow your liquidity. Access and management of our fund are done directly from your Memo Bank workspace, completely autonomously.
Funds available within 24 hours
The funds are highly liquid. From your workspace, you can initiate withdrawals in the same way as subscriptions. Orders are processed daily, and you receive the funds within 24 to 48 hours.
Transparent pricing
Annual management fees amount to 0.25%, charged daily on a pro-rata basis on the assets under management. The displayed interest is always net of these fees, ensuring full clarity on the yield.
