Understanding this result

Where it stands today

The high yield was 3.820% at this 30-year bond auction, the median yield 3.755% and a bid-to-cover ratio of 2.73.

What do these figures measure?

The high yield is the highest rate Treasury accepted; every winning bidder gets it. The bid-to-cover ratio is bids received divided by the amount sold. Shares are of competitive bids accepted. High minus median shows how far the accepted cut-off sat above the middle accepted bid; it is not the market's auction tail, which needs a when-issued price that is not public.

How does it compare with the par yield curve?

The par yield curve comparison sets the high yield against Treasury's own par yield curve on the auction day, at the point nearest this security's maturity (30-year). Treasury fixes that curve from market quotes in the late afternoon, after the auction closed, so the gap mixes the auction's pricing with the afternoon's market move. It is not the auction tail either.

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 auction tail as markets quote it. That compares the high yield with the when-issued yield just before bids closed, a market price that is not public; we show high minus median instead, a different measure.
  • Who the bidders are. Indirect bidders include foreign and international accounts bidding through the New York Fed and investors bidding through dealers; Treasury does not publish names.
  • Demand on another day. A bid-to-cover ratio counts bids at one auction against the amount offered, and the amount offered changes from auction to auction.
