TREASURY ANNOUNCES BILL AUCTIONS FOR ISSUANCE ON JUNE 6 AND POSSIBLE CMBS
The Treasury bill auctions announced today would represent a net paydown of marketable debt when the securities are issued on June 6. In addition to the 4-, 8-, and 17-week bill auctions announced today, Treasury anticipates that issuance of several cash management bills (CMBs) will be necessary in the coming days. Treasury has enough headroom under the current debt limit to issue all of these securities. However, the cash raised by the issuance of these securities may be insufficient to satisfy all of the government's obligations if Congress has not raised or suspended the debt ceiling by June 5.

On the bottom click on the expansion arrow next to CMB to see all issuances for any given calendar year.



If a three day Treasury was too long for you to hold, there is an auction of 1 day paper on 06/02/23.
