About United Kingdom Overnight Interbank Average Rate
SONIA (Sterling Overnight Interbank Average Rate) is based on actual transactions and reflects the average of the interest rates that banks pay to borrow sterling overnight from other financial institutions and other institutional investors. Financial businesses and institutions use SONIA in a variety of ways. For example, to calculate the interest paid on swap transactions and sterling floating rate notes . SONIA is used to value around £30 trillion of assets each year. SONIA is the Working Group on Sterling Risk Free Reference Rates’ preferred benchmark for the transition to sterling risk-free rates from Libor.
