What is a money market ETF?

A "money market ETF" generally refers to an ETF that invests in very short-term, high-quality instruments to provide cash-like exposure. Availability and structure can differ depending on local rules.

The core idea is similar to a money market fund: preserve capital, maintain high liquidity, and provide a yield close to short-term rates. But because it trades on an exchange, pricing and mechanics can differ.

If you use one for cash management, check credit quality, maturity profile, fees, and how closely it maintains stability. Also be aware that cash-like doesn't mean risk-free; liquidity events can still matter.
