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.

About this desk

The United Kingdom desk leads with Bank Rate, the Bank of England's policy rate, then SONIA, the sterling overnight market benchmark the Bank publishes but does not set. Euro-area, US, Canadian and Australian rates follow, with the rest of the build's series after them. All desks republish the same official series; this desk only reorders the menu and the wording, so the figures do not change when you switch desks.

Both UK series come from Bank of England statistical tables and are republished under the Bank's open-data terms, with attribution. Bank Rate is a policy setting that moves at MPC decisions; SONIA is a transaction-based market rate that moves daily. The build does not publish a UK retail mortgage or savings rate, because no such official series is ingested here — those pages are absent rather than estimated. This is not financial advice.
