Treasury Bill (T-Bill)

A Treasury bill (T-bill) is short-term debt issued by the United States government with a maturity of one year or less, commonly 4, 8, 13, 17, 26, or 52 weeks. T-bills pay no coupon; they are sold at a discount and redeemed at face value, the difference constituting the holder's return.

Why it matters

T-bill yields are the closest thing global finance has to a risk-free rate, the baseline against which every other investment is judged. Trillions of dollars of bills are outstanding, money market funds hold them as their core asset, and their yield sets the opportunity cost of holding anything that pays nothing. When bills yielded near zero from 2009 to 2021, non-yielding assets were nearly free to hold; when yields pushed above 5% in 2023, every gold and bitcoin allocation had to clear a 5% hurdle. Stablecoin issuers have also become significant T-bill buyers, with Tether alone reporting holdings comparable to those of mid-sized sovereign nations, an unexpected bridge between crypto and the Treasury market.

In the gold vs bitcoin debate

The T-bill is the honest benchmark for both assets. Gold and bitcoin pay no interest, so their case rests on price appreciation and on doubts about the system that stands behind the risk-free rate itself, including inflation that can leave bill holders with negative real returns, as in 2021-2022. Advocates of both assets make the same wager from different directions: that over long horizons, the issuer's currency will lose purchasing power faster than its bills compensate.
