TIBOR: The Tokyo Interbank Offer Rate

An in-depth look at TIBOR, a key interest rate benchmark in Japan, reflecting interbank lending rates.

Historical Context

The Tokyo Interbank Offer Rate (TIBOR) is a critical financial benchmark in Japan, first introduced by the Japanese Bankers Association (JBA) in 1995. It functions similarly to other international interbank rates like the LIBOR (London Interbank Offer Rate) but is specific to the Japanese financial markets. TIBOR indicates the average interest rates at which banks in Tokyo are willing to lend to each other.

Types/Categories

TIBOR is divided into two main categories:

• Japanese Yen TIBOR: Reflects unsecured call rates in the Tokyo money market.
• Euroyen TIBOR: Indicates interest rates for Japanese banks borrowing offshore in foreign currencies, primarily focusing on the Euro.

Key Events

• 1995: Introduction of TIBOR.
• 2013: Reforms in the calculation methodology to enhance transparency and reliability.
• 2021: Phasing out of certain global benchmark rates (including LIBOR) renewed interest and scrutiny towards TIBOR.

Detailed Explanations

Calculation

TIBOR is calculated based on the average interest rates submitted by selected banks, which reflect their actual borrowing costs. These banks report their rates at specified times, and the outliers are removed to calculate a trimmed mean.

Mathematical Formulas/Models

The calculation model involves:

$$ \text{Trimmed Mean} = \frac{\sum_{i=1}^{n} \text{Rate}_i - \text{Highest Rate} - \text{Lowest Rate}}{n-2} $$
