Strategy: Cash equivalent
Funds holding short-dated US government paper, where the objective is that the principal is there when you need it. Yield follows short-term interest rates with a short lag rather than being locked in, so income falls when the central bank cuts and rises when it hikes. Because the underlying holdings are nearly identical across providers, the expense ratio comes almost directly out of what you receive.

There is no growth here by design, and purchasing power erodes whenever the after-tax yield sits below inflation.

What BIL vs BOXX actually do

State Street's Treasury bill fund, holding bills with one to three months left to maturity.

It tracks a Bloomberg index of 1 to 3 month US Treasury bills and works the same way as its peers: constant rollover, a yield that follows the short end of the curve, and monthly distributions. It launched in 2007, well before the current crop of cash ETFs, and carries a higher expense ratio than the newer entrants. On a product where every fund holds nearly identical government paper, that fee gap comes almost directly out of the yield you receive.

Suits anyone needing a liquid cash holding, particularly where a platform makes it the cheapest or most accessible option. Where an equivalent bill fund charges less, there is little in the portfolio itself to justify the difference.
