TONAR
Tokyo Overnight Average Rate (TONA rate or TONAR) or Japanese Yen Uncollateralized Overnight Call Rate (Japanese: 無担保コールO/N物レート) is an unsecured interbank overnight interest rate and reference rate for Japanese yen.[1][2][3] Mutan rate and TONA rate are the same things.
Japanese yen uncollateralized overnight call market started in July 1985.[4]
Since December 28, 2016, the Bank of Japan has recommended the TONA rate as the preferred Japanese yen risk-free reference rate.[5][6]
TONA rate is recommended as a replacement for Japanese yen LIBOR, which was phased out at the end of 2021, and Euroyen TIBOR, which will be terminated at the end of 2024.[3][7][8][9]
