About Japan's policy rate

BIS central-bank policy rate for Japan (WS_CBPOL, JP). Current: 1.00% on 17 Sep 2026. The series follows the instrument the BIS and the Bank of Japan treat as the policy rate in each period — today the uncollateralized overnight call rate. Compiled by the BIS with the Bank of Japan.

The chart is a step at policy changes. From 1 Jan 1946 to 17 Sep 2026 (29,480 observations): mean 3.40%, median 3.65%; low -0.10% (21 Sep 2016), high 9.00% (22 Dec 1973). Not a mortgage or deposit rate. This page is not an official BIS publication.

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

Italy has no separate policy rate here. The Italy desk leads with the ECB deposit facility rate and €STR, the shared euro-area policy and overnight market series, then UK and US rates. Italy's monetary policy is set by the ECB Governing Council, so the desk uses the euro-area series rather than a Banca d'Italia policy rate that would misrepresent the framework.

Germany, France, Ireland and the /ea/ desk carry the same two ECB series. The figures come from the ECB Data Portal and are republished with attribution under the ESCB statistics reuse policy. Every desk shows the same series in a different order, so switching desks changes the menu and wording, not the numbers. The build ingests no Italian retail rate series, so none is shown. This is not financial advice, and readings may lag their source.
