Reading this series

Japan's policy rate here is the BIS central bank policy rate series for Japan (WS_CBPOL), compiled by the Bank for International Settlements with the Bank of Japan. The BIS series follows whichever instrument the authorities treat as the policy rate in each period; today that is the uncollateralised overnight call rate, while older stretches reflect earlier frameworks. It is stored as dated level changes and shown as a daily step series, because policy changes only on Bank of Japan decision dates.

Read the headline with its as-of date, then the "versus the previous reading" line; when the rate has been unchanged the page surfaces the date of the last actual move. Mean, median, low and high are arithmetic summaries of the observations in this build, not official aggregates. Chart and Table show the same series two ways, range buttons filter the drawn window, and Explore loads zoom and pan on request. The BIS rate is a compiled policy measure, not a mortgage or deposit rate, and this page is not an official BIS publication.
