Notes
This database provides statistics on changes in official discount rates over the years 1882 through 1941. Data prior to July 1906, when official discount rates were standardized across all branches, covers interest rates at the Osaka, Saibu, Hokkaido, and Fukushima branches, in addition to the Head Office. Since official discount rates at the Sapporo, Otaru, Kyoto, Hiroshima, and Taipei subbranches and the Nagoya Branch were identical to those at the Head Office or the branches above, they are covered in the table attached entitled "Other Branches and Subbranches." In addition, since certain rates were provided as daily rates and others as annual rates until the listing of official discount rates was standardized on daily rates in December 1890, this database provides both daily and annual rates together, in accordance with the original data, with the exception of certain periods during the 1880s. This data is drawn from pp. 350 - 357 and pp. 374 - 377 of Bank of Japan: The First Hundred Years: Materials published by the First Hundred Years' Editing Committee, Bank of Japan in 1986.
