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 Sweden desk leads with the Riksbank policy rate, styrräntan, from the BIS central bank policy rate series for Sweden, then Norway, ECB and UK rates. Since 1994 the series is the repo rate; earlier stretches splice the marginal rate and the discount rate, which were the policy instruments of their day. The BIS stitches them into one comparable series, drawn as daily steps. It is a policy rate, not a retail lending rate.

All desks show the same official series in a different order, so the numbers do not change when you switch. Values are republished with attribution to the BIS; this site is not an official BIS publication. The build ingests no Swedish mortgage or deposit series, so those pages are absent rather than estimated. This is not financial advice.
