Price of one USYC, every published round

from the oracle the Teller reads · one price a business day

What this is

USYC is Circle's tokenized money market fund, invested in short-term US Treasuries. On Arc, a Teller contract mints USYC for USDC and redeems it for USDC at the price an oracle publishes once a business day, so that price is what one USYC is worth. Who can hold it: institutions outside the United States, allowlisted by Circle, with a $100,000 minimum.

The growth figures take the price change over the window and compound it to a year. That is the fund's return after its fees, as the price shows it. It is past growth, not a promise.
