Choosing between BlackRock funds and Treasury ETFs
Check the ticker and share class. A money-market mutual fund and a Treasury ETF have different trading, yield, and cash-access mechanics.
- SGOV
- SGOV holds Treasury bills with maturities of zero to three months and reports a 30-day SEC yield. It trades on an exchange, so your purchase price and trading costs affect the result. It is not an FDIC-insured savings account. Source
- Tax comparison
- Use fund-specific tax-year allocations when estimating state tax exemption. A Treasury fund's name alone does not establish the exempt percentage of its distributions. Source
