How to Read US Treasury Auction Results
Understand high yield, bid-to-cover, bidder participation and reopenings in official Treasury auction data.
High yield and applicable bill rates
For coupon securities, the official high yield is the yield accepted at the auction's stop. Treasury bills instead publish discount and investment rates. These official values are not the same thing as an auction tail versus the when-issued market.
Bid-to-cover
Bid-to-cover divides total tenders by the amount accepted. It is useful in same-series historical context, but raw ratios should not be treated as directly comparable across unlike securities or issuance regimes.
Bidder participation
Direct bidders, indirect bidders and primary dealers are official allotment categories. Their accepted shares describe allocation, not investor intent, nationality or a guaranteed market-price response.
Reopenings
A reopening sells an additional amount of an existing security. Squawkdeck preserves reopening status and compares the result with the same normalized series while showing the distinction.
