Starting with CUSIP# 912797MU6 to be auctioned on February 18, 2025, the Treasury is transitioning the 6-week CMB (Cash Management Bill) to benchmark status. Apparently, the transition merely changes the product identification from “6-week CMB” to “6-week BILL”

“As announced at the May 2024 quarterly refunding, Treasury plans to transition the 6-week CMB to benchmark status. During the transition, Treasury will continue to issue the 6-week CMB at a regular weekly cadence. Treasury anticipates that the first benchmark 6-week bill auction will be announced on February 13, 2025, and auctioned on February 18, 2025. As noted previously, Treasury intends to maintain the Thursday settlement and maturity cycle for the 6-week benchmark bill.”
