Yield curve control (YCC) is a monetary policy tool used by the Bank of Japan (BOJ) to control the yield curve of Japanese government bonds. The purpose of YCC is to maintain a stable and low interest rate environment, which supports economic growth and helps to achieve the BOJ’s inflation target of 2%.
Under YCC, the BOJ sets a target yield for 10-year Japanese government bonds and conducts open market operations to purchase or sell bonds to control the yield curve and keep it in line with the target rate. The BOJ also commits to purchasing government bonds in unlimited quantities to keep the yield at the target level, if necessary.
The main benefit of YCC is that it provides greater clarity and predictability for market participants regarding the BOJ’s monetary policy stance. By committing to a specific target yield for Japanese government bonds, the BOJ can help to anchor long-term interest rates and provide stability to financial markets. This can support borrowing and investment activities, which can in turn stimulate economic growth.
One potential side effect of YCC is that it could reduce the effectiveness of the BOJ’s monetary policy tools over time. If the BOJ is seen as having a firm commitment to maintain low interest rates through YCC, market participants may be less responsive to changes in other monetary policy tools such as interest rate adjustments or asset purchases. Additionally, the BOJ’s commitment to purchasing government bonds in unlimited quantities could potentially lead to concerns about fiscal sustainability and inflation expectations in the long run.
