Treasury also plans to add a 2-month CMT to the Daily Treasury Yield Curve Rates and 8-week bill rates to the Daily Treasury Bill Rates that it publishes.

Changes to the published tables and data files to accommodate the additional rates will appear beginning in the evening of October 14, 2018.

Daily Treasury Bill Rates: These rates are the daily secondary market quotation on the most recently auctioned Treasury Bills for each maturity tranche (4-week, 8-week, 13-week, 26-week, and 52-week) for which Treasury currently issues new Bills. Market quotations are obtained at approximately 3:30 PM each business day by the Federal Reserve Bank of New York. The Bank Discount rate is the rate at which a Bill is quoted in the secondary market and is based on the par value, amount of the discount and a 360-day year. The Coupon Equivalent, also called the Bond Equivalent, or the Investment Yield, is the bill's yield based on the purchase price, discount, and a 365- or 366-day year. The Coupon Equivalent can be used to compare the yield on a discount bill to the yield on a nominal coupon bond that pays semiannual interest.
