What these figures cannot tell

  • Why it sold where it did. Results show what was bid and accepted, not the reasons behind any bid.
  • The cost over the bill's life in other terms. The discount rate is Treasury's quoting convention; the investment rate states the same result as a bond-equivalent yield.
  • Demand on another day. Bill sizes change week to week, so a bid-to-cover ratio is comparable only with care.
