Crane Data's latest Money Fund Intelligence International shows that assets in European or "offshore" money market mutual funds decreased slightly over the past 30 days to $1.670 trillion, decreasing from a record high $1.672 trillion the month prior. Yields were mixed, while assets for USD, EUR and GBP MMFs all inched lower over the past month. Like U.S. money fund assets, European MMFs have repeatedly hit record highs in 2023, 2024, 2025 and 2026. These U.S.-style money funds, domiciled in Ireland or Luxembourg and denominated in US Dollars, Pound Sterling and Euros, decreased by $10.0 billion over the 30 days through 5/13. The totals are up $85.3 billion (5.4%) year-to-date for 2026. They were up $151.9 billion (10.6%) for 2025, up $235.3 billion (19.7%) for 2024 and up $166.9 billion (16.2%) for the year 2023. (Note that currency moves in the U.S. Dollar cause Euro and Sterling totals to shift when they're translated back into totals in USD. See our latest MFI International for more on the "offshore" money fund marketplace. These funds are only available to qualified, non-U.S. investors and are almost entirely institutional.) (Note too: Mark your calendars for our next European Money Fund Symposium, which will be held Sept. 24-25 in Paris, France.)
