Each line is a currency's broad money supply (M2 / M3), indexed to 100 at the first year of the selected window so they're directly comparable. Log scale. Toggle currencies on or off — USD is always on as the baseline. Hover the chart for a year-by-year crosshair showing the index value of every visible currency at that year. Each line begins when published data begins for that currency (HKD: 1990, CNY: 1985, TWD: 1981, EUR/JPY/USD: 1980).
