Yield, fees & minimum
SPDR Bloomberg 1-3 Month T-Bill ETF (BIL) is an exchange-traded fund from State Street (SPDR) holding treasury securities, with a 0.1353% expense ratio and a One share (about $92) minimum. Its 30-day SEC yield (3.59% (30-day SEC yield, 2026-09-18)) moves with short-term rates — confirm the current figure on the official page. State tax: holds only 1-3 month u.s. treasury bills, so nearly all income is typically exempt from state and local tax. It is not an automatic sweep — you buy and sell it yourself. Because it trades on an exchange, its share price floats rather than holding at $1.00, it can trade slightly above or below net asset value, and a sale settles on the normal trade-settlement cycle instead of being available the same day.
The bottom line
The original 1-3 month T-bill ETF, launched in 2007, with deep liquidity Main drawback: at 0.1353% it costs roughly half again what sgov charges for near-identical exposure.

We summarize the fund's published facts, not user reviews. 7-day yields are variable, change daily, and are re-checked against State Street (SPDR)'s official page. Money-market funds are not FDIC-insured and, while low-risk, can lose value in extreme conditions.
