National Express Group has taken out a bilateral SONIA loan facility from NatWest.
The deal is the first UK corporate loan to use SONIA (Sterling Overnight Index Average) an overnight interest rate paid by banks for unsecured transactions in the British sterling market.
It is being used as a new reference point as banks pivot away from LIBOR.
The revolving credit facility represents the first in a pilot scheme run by NatWest to offer SONIA loans to corporate customers.
According to the FT, global regulators intend to move markets off of LIBOR by the end of 2021.
National Express is a bus, coach and rail operator that undertook nearly 900 million journeys in 2018.
