Periodical revisions have been made to the data for broadly-defined liquidity in the Money Stock Statistics.
The data for broadly-defined liquidity is revised "when the Bank finds much room for improvement on the accuracy of the data. Added to this, every three years (in June), the Bank examines whether or not the data needs to be revised, and if so, revises them accordingly ("Introduction of Periodical Revision of Broadly-defined Liquidity," June 8, 2004, Research and Statistics Department, Bank of Japan)."
The data for broadly-defined liquidity is retroactively revised in line with the release of the International Investment Position of Japan (end of December 2006), etc.
With this revision, the data from January 2000 to April 2007 have been revised. To download the file for the revised figures, please click the file below:

The amount of clearing government bonds held by money holders is calculated using Bank of Japan studies such as the "Research for the Holders of Clearing Government Bonds." To increase the estimation accuracy, the "Outstanding of Clearing Government Bonds by Type of Government Bonds" will also be used.
Foreign bonds are calculated by adding every month the investment amount of foreign bonds during the month (flow) held by money holders estimated from the Balance of Payment Statistics to the amounts outstanding of foreign bonds (stock) held by money holders at the end of every December based on the International Investment Position of Japan. The monthly currency fluctuations are also incorporated into the stock of foreign bonds. Apart from this, foreign bonds held by life insurance companies, non-life insurance companies, and trust accounts of domestically licensed banks are estimated and adjusted. The major changes in this estimation method are as follows:

The assets of the Postal Life Insurance Welfare Corporation were transferred to the Japan Post due to the dissolution of the corporation on April 1, 2003.
Since the Postal Life Insurance Welfare Corporation is regarded as "general corporation" and the Japan Post as "financial institutions," this transfer decreases the Money Stock Statistics1. The amounts outstanding of Broadly-defined Liquidity excluding the assets of the corporation are as below: 2
