NEW YORK — Americans are still treating money-market funds as a default checking account for cash they do not need this week.
Industry data show balances remain near cycle highs even after a year of debate about when the Fed would cut. As long as policy rates stay elevated, funds that hold short-term Treasuries and repurchase agreements can advertise yields that outpace the typical brick-and-mortar savings rate.
Banks have reasons not to match those yields. Deposit costs already pressure net interest margins. Many customers still leave cash in accounts that pay a fraction of a percent — a habit that is expensive to disturb with a headline rate on every statement.
The practical difference for a household with $20,000 in cash is no longer trivial. Over a year, the gap can run to hundreds of dollars. That arithmetic has spread beyond finance blogs and into workplace conversations, several advisors said.
There are trade-offs. Money-market funds are not FDIC-insured in the way a bank account is, though government and Treasury funds are built around high-quality short-term paper. Transfers are easy; they are not instant in every app. Settlement quirks still catch people who treat a fund like a debit card.
If the Fed eases later this year, fund yields will follow down. The question for banks is whether customers who learned to move cash will move it back — or keep shopping for the next 4 percent.
