On June 30, 2023, the US dollar London Interbank Offered Rate (Libor) bank panel stopped publishing its rates – or ‘settings’, as they are more properly known. The date marked the end of operations for the last remaining Libor panel.
A handful of US dollar settings – for one-, three- and six-month tenors – will continue to be calculated synthetically until September 2024 to cater for some existing contracts, after which Libor will finally be a thing of the past. Most of the US market has transitioned to rates linked to the Secured Overnight Financing Rate (Sofr), which is based on the overnight repo market for Treasuries.

Other US dollar tenors continued until the June 30, 2023, deadline (and a three-month sterling synthetic Libor will run until the end of March 2024).
