Libor X: SOFR SONIA SARON

About this app

LIBOR is gone. Libor X 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. Libor X 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. FREE, AND AD-FREE IF YOU LIKE Libor X is free and complete, supported by ads. From the Info tab you can remove them for one year, with an auto-renewing subscription, or for good, with a one-time purchase. The features are the same either way. Payment is charged to your Apple Account at confirmation. The subscription renews automatically at the same price unless cancelled at least 24 hours before the end of the period; manage or cancel it in your Apple Account settings. Had the paid version, now called Libor Legacy? Open the updated Libor Legacy once and install Libor X on the same iPhone: the ads disappear on their own. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://bacchin.app/app/LiborX/privacy.html Libor X is an information app and does not provide financial advice.

• Fewer interruptions: full-screen ads no longer appear over a chart or during a purchase, and wait for a natural pause. • The banner no longer leaves an empty space while it loads. • "Remove ads" is now one tap away, right under the banner. • New icon.

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.
