Mirrored U.S. Treasuries

This page mirrors every U.S. Treasury bill active today, including original issuances and reopenings. Each T-bill is an individual contract deployed on a dedicated Anvil instance that is rebuilt when the official Treasury data changes.

A bill may be auctioned more than once under the same CUSIP and maturity date:

  • 52-week bills can later be reopened with 26, 13, or sometimes 6 weeks remaining.
  • 26-week bills can later be reopened with 13 or 6 weeks remaining.
  • 17-week bills are separate original bills that can later be reopened with 8 or 4 weeks remaining.
