The BOJ Uncollateralized Overnight Call Rate, the most important interest rate for the Bank of Japan: what is it and what does it correspond to?

Uncollateralized call rates, such as the "BOJ Uncollateralized Overnight Call Rate" (UOCR), refer to short-term interest rates in unsecured markets between financial institutions. The rate is characterized by the exchange of funds on the contract date between financial institutions and repayment on the next business day . Since 1990, this rate has been a focal point for the Bank of Japan's money market operations. The guidelines established by the Bank aimed to keep this rate around a specific average percentage. Market operations were conducted by regulating the funds' balance sheets through open market operations, managed by the Department of Financial Markets. Total funds within the financial markets were held constant unless changed by: conversions into banknotes, changes in treasury funds, or other transactions. Accurately predicting these changes in funds was critical to effective market operations. In addition to open market operations, the Complementary Lending Facility serves as a mechanism to control the unsecured overnight call rate by offering overnight loans with a set maximum rate.
