Method

Method: the set is the ten largest non-USD currencies by OTC turnover in the BIS 2025 Triennial Survey. Each rate is expressed as the USD value of one unit of currency. Returns are first-to-last changes; volatility is sample standard deviation (n−1) of daily log returns. Variance is shown in basis-points-squared (bp²), so small values remain readable.
