Brief overview of “JGBs held by BoJ”

The Bank of Japan (BoJ) is currently aiming to lengthen the duration of JGB holding. In its policy statement in April 2013, it pledged that it will target to purchase JGBs with 7 years remaining maturity on average. However, the BoJ does not officially publish the duration related statistics on their JGB holding or of its monthly purchase. We, Japan Macro Advisors, estimate these statistics. These data are our proprietary data, but we permit the free use of statistics on condition that users display the source (JMA) publicly. The average duration of the BoJ’s JGB holding had been steadily falling between 2011 to early 2013 until the new BoJ Governor Haruhiko Kuroda introduced “Quantitative and Qualitative Monetary Easing” in April 2013.
