Money Funds Meet Zero Yields by Breaking Buck Taboo: Euro Credit

Investors in Europe risk losing a haven as Goldman Sachs Group Inc. (GS), JPMorgan Chase & Co. (JPM) and Morgan Stanley break a taboo that’s stopped 88 billion euros ($113 billion) of money-market funds from ever losing principal.
The banks are preparing to abandon the policy that investors get one euro back for every one they put in as government bond yields near record lows make it harder for the funds to generate returns.
A money-market fund failing to repay investors in full is said to “break the buck” and is forced to shut down.
