Our read on GMMF
BMoney market funds price once a day. GMMF puts one on an exchange: an iShares government cash strategy whose stated job is current income with liquidity and stability of principal, plus intraday trading.
The fund seeks current income consistent with liquidity and stability of principal, while providing intraday exchange trading.
Why people hold it
- The mandate is literal: current income consistent with liquidity and stability of principal, plus intraday exchange trading. What it holds lines up with what the label says.ishares.com
- Roughly 50 positions in short-dated US government paper, run by iShares. A cash sleeve you can buy and sell during market hours like any stock.
- The 0.20% fee sits right at the median for cash-alternative ETFs, so the exchange-traded wrapper does not come at a price premium.
Worth knowing
- Trading is thin. Bid-ask spreads can run wider than in the heavily traded cash ETFs, which shows up most on large or hurried orders.
- It launched in 2025, so the track record is short and covers a single rate backdrop. Stability of principal is the stated objective, not a promise.
- Cheaper cash parking exists: ICSH charges 0.08% and JPST 0.18%, though both are ultra-short bond funds rather than money market strategies.
