LiborX Light: SOFR SONIA

About this app

LIBOR is gone. LiborX Light follows the rates that replaced it. For half a century LIBOR was the most important number in finance: hundreds of trillions of dollars in loans, mortgages and derivatives depended on it. After the rate-rigging scandals it was retired, and every major currency moved to an overnight benchmark built on real transactions. LiborX Light brings them together in one app. FOUR CURRENCIES, ONE SCREEN • SOFR — United States, Federal Reserve Bank of New York • SONIA — United Kingdom, Bank of England • SARON — Switzerland, SIX Swiss Exchange • TONAR — Japan, Bank of Japan THE TERM SOFR CURVE CME Term SOFR at 1, 3, 6 and 12 months is the closest successor to the old USD LIBOR fixings, and it is what business lending is priced against today. Each tenor gets its own card and chart, and the shape of the curve shows where markets expect the Fed to go. WHAT YOU GET • Daily fixing with the change from the previous day • Full history, from one month to the entire available series • Interactive chart: drag to read the value on any date • All four currencies compared on a single chart • A ranking of who pays the most, updated every fixing • The curve read for you: upward, flat or inverted • Notifications when new fixings are published • Works offline with the last downloaded data • iPhone and iPad, light and dark • VoiceOver and Dynamic Type WHERE THE DATA COMES FROM Every rate comes from the official administrator that publishes it. Fixings are released once per business day and appear here after a short delay. THIS VERSION LiborX Light has the same data and the same features as the full version and is supported by ads. If you would rather read the rates without them, there is Libor X. LiborX Light is an information app and does not provide financial advice. Values may differ from official publications: always verify with the administrator before making decisions.

LiborX Light 5.0 is a complete rewrite. • No longer just USD LIBOR: the four rates that replaced it are here — SOFR, SONIA, SARON and TONAR • The CME Term SOFR curve at 1, 3, 6 and 12 months, each with its own chart • Interactive charts with full history and statistics • Cross-currency comparison and an automatic reading of the curve • A new interface for iPhone and iPad, light and dark • Notifications for new fixings • VoiceOver and Dynamic Type support • Five languages

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
