RNJPBIS as published (index, 2020 = 100), from January 1986BIS real narrow effective exchange rate for Japan (RNJPBIS), monthly, index 2020 = 100. Lower means the yen is weaker after adjusting for inflation and movements against Japan's major trading partners. Unlike the bilateral USD/JPY rate, the index weights exchange rates by trade and strips out relative consumer prices, so it tracks purchasing power rather than a single currency pair.
