Bank for International Settlements real effective exchange rate of the yen: the trade-weighted value against 64 economies, adjusted for relative consumer prices, monthly average, 2020 = 100. A lower reading means the yen buys less abroad and Japan is cheaper for visitors — 66.0 in August 2026 against 90.7 in January 2015. Published mid-month for the previous month; BIS revises the whole history when it re-weights.

floortok processing: Rounded by floortok from BIS's two decimals to one. The index itself is BIS's: monthly average of daily data, broad basket of 64 economies, 2020 = 100. BIS re-weights and revises the whole history, so the full series is re-pulled each month.
