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

The Taiwan desk leads with the CBC discount rate, the policy rate set by the Central Bank of the Republic of China (Taiwan), then US, Japan and Korea rates, with the rest following. The discount rate is read from the CBC Statistical Database as series EG28D01en and drawn as daily steps: the rate is flat between board meetings and changes on decision dates. It is a policy instrument, not a mortgage or deposit rate.

All desks show the same build-wide series in a different order, so the numbers here match the hub. Values are republished from official files without alteration and each page names the source and licence. The build ingests no Taiwanese retail rate series, so those pages are absent rather than estimated. This is not financial advice, and readings may lag their source.
