As the world of finance continues to evolve, financial services professionals are always seeking new and improved methods for managing risk, making informed decisions, and growing their businesses. One alternative reference rate that is gaining traction in the financial industry is TONA (Tokyo Overnight Average Rate), which is an alternative reference rate for the Yen London Interbank Offered Rate (JPY LIBOR).
TONA is a pre-existing OIS rate.The domestic version of TIBOR (DTIBOR) will continue to be used whilst Euroyen TIBOR (ZTIBOR) is most likely to be ceased.
TONA reflects the average overnight cost of unsecured borrowing in the Japanese market. It is designed to provide a stable and transparent measure of the cost of borrowing in Japan, and is calculated using data submitted by participating financial institutions.
TONA is calculated by the Bank of Japan (BOJ) based on the weighted average of interest rates charged by major financial institutions for overnight loans in the Japanese interbank market. The BOJ collects data on interest rates and credit conditions in the interbank market every business day and publishes the TONA on its website.
As a rate that is based on actual market transactions, it provides greater transparency and reduces the risk of rate manipulation. This in turn helps to ensure the stability and reliability of the financial markets in Tokyo
The transition to TONA as an alternative reference rate brings several benefits to financial services. These features include:
Setting interest rates on loans and financial products
Evaluating the cost of borrowing and lending in Japan
Making informed investment decisions
Hedging against interest rate risk
Calculating the value of financial derivatives and other securities
Monitoring market trends and conditions in Japan’s financial sector.
