Role of tanshi companies

Tanshi companies are specialized intermediaries in the interbank market that mediate the lending and borrowing of call funds (unsecured overnight, etc.), bill sales, CD/CP sales, etc. between banks. This business format is unique to Japan and contributes to improving the efficiency of the call market and smoothing the Bank of Japan’s financial operations. It is also the main counterparty of the Bank of Japan’s operations and occupies an important position in the transmission mechanism of policy interest rates.

Industry structure (3 Large short-term investment oligopoly)

3 社Japan’s short-term money market intermediation was dominated by the government. They compete closely with each other in terms of human resources and transaction flow.

The hardships of the era of negative interest rates

2009 After Lehman ~2024 Until negative interest rates were lifted, the money market’s trading volume and spreads were shrinking due to ultra-low and negative interest rate policies, and the money market industry was in a long-term contraction phase. Factors putting pressure on performance include sluggish call market trading volume, excess liquidity at banks, and overemphasis on current account deposits at the Bank of Japan.

2024~ Expectations for revival with normalization of policy interest rates

• 2024-03 Lifting of negative interest rates (Bank of Japan) → Activation of call market
• 2024~ Gradual interest rate hike phase → Short-term interest margin expansion
• Recovery in demand for money brokerage → Expected to improve profitability in the industry as a whole
