The iShares Prime Money Market ETF strives to generate strong current income, always balancing this goal with the critical needs for investment liquidity and the steadfast preservation of principal.

As the hunt for yield and stability remains a cornerstone of portfolios in 2026, a group of iShares short-term bond ETFs have made a strategic move to the Big Board today. Four prominent short-term fixed-income vehicles have officially transitioned their primary listing to the New York Stock Exchange (NYSE).

The iShares Prime Money Market ETF (PMMF) eliminates duration risk amid growth rebound considerations and inflation still running hot. However, a growth rebound also makes some credit risk more appealing at the moment at low durations, provided by FLOT which also has a very low duration. Expense ratios are also lower on effectively similar low duration alternatives.

Multiple factors, including questions around interest rates, persistent inflationary pressures, and global volatility, are shaping the fixed income landscape in 2025. As investors seek ways to navigate uncertainty and maintain liquidity during periods of market stress, several key product launches have emerged in fixed income.

PMMF is a newly launched ETF designed to offer intra-day trading liquidity for money market fund-like investments, adhering to SEC Rule 2a-7. This distinguishes it from traditional money market funds that operate with end-of-day NAV calculations. While aiming for high current income with liquidity and principal stability, PMMF's holdings, which include bank deposits and tri-party repos, introduce some counterparty credit risk, unlike pure T-Bill ETFs.

Money market mutual funds have long been a popular cash management tool for investors looking to park cash short-term, while preserving capital and picking up some return and yield. Now, there are money market ETFs for that, too.
