A bond auction is the process by which governments sell newly issued bonds to investors through competitive or non-competitive bidding. In a competitive bid, investors specify the yield they are willing to accept, while non-competitive bidders agree to accept whatever yield is determined by the auction. Key metrics from bond auctions include the bid-to-cover ratio and the tail (difference between the highest accepted yield and the average yield), both of which indicate demand strength. Auction results can significantly impact bond, equity, and currency markets.
Example
“The 30-year Treasury bond auction came in with a bid-to-cover ratio of 2.5x, signaling strong demand and pushing yields lower.”
