Japan’s foreign exchange intervention record from the Ministry of Finance: every dated operation since April 1991, the quarterly totals, and the latest monthly release.

Tools

• japan_fx_intervention(start_date?, end_date?) — dated operations in the range (ISO dates; amount in 100 million yen, direction, currency pair), quarterly totals for the quarters in the range, and the latest monthly release (period, total, release date). With no dates it returns the most recent operations (last 3 years), the matching quarterly totals and the latest monthly release. A quarter or month with no intervention is a published figure of 0 and is returned as 0, not omitted.

Data sources

• Ministry of Finance Japan, Foreign Exchange Intervention Operations: the historical record of operations, the quarterly totals, and the monthly release. Covers actual operations only, not verbal warnings or statements. Daily figures are rounded by the publisher, so they may not sum exactly to a quarterly total. Non-yen operations are converted to yen by the publisher at the Bank of Japan central rate. Every response carries data_as_of.

The historical file is Shift_JIS encoded and fetched live on each call; the monthly release is a human page parsed for its period and total, and the pack errors loudly if either format changes.
