Official exchange rate (LCU per US$, period average)

Japan ranks first at 149.66. Fastest compound growth over the period is Japan at +2.1% per year; the slowest is United States at +0.0%. Fitted trend is steepest upward in Japan (+3.3%, per year of its own mean level, R² 0.588) and weakest in United States (+0.0%, R² 1). Largest acceleration — last three years against the three before — is China at +2.9% percentage points. The largest covered value is 149.7× the smallest. 3 economies covered; latest observation year 2025. Note: for this indicator a higher value is adverse, so a rising series is not a positive signal.

Trend is the ordinary-least-squares fit of value on year, reported with its R² — how much of the movement the straight line explains, as a percentage of the period mean level so economies of different size are comparable. Momentum is the mean change of the last three years minus the mean of the three before it, in percentage points. Half-period shift compares the second half of the window against the first. Volatility is the standard deviation of year-over-year change. Outlier years exceed 2.5 standard deviations from that economy's own average change.

MethodologySeries are pulled from the official source API and null observations dropped. CAGR = (end/start)^(1/years) − 1. Index uses the first year of the range as 100. Trend is an OLS fit of value on year, reported as a percentage of the period mean alongside its R². Volatility = standard deviation of year-over-year percentage change (percentage points). Momentum compares the last three years against the three before. Share = economy value ÷ sum of the covered economies. HHI = sum of squared shares; its reciprocal estimates the number of evenly sized economies. Cross-indicator correlation is Pearson's r on pooled year-over-year changes.
CoverageRequested: 1 indicator(s) × 3 economies × 11 years = 33 cells; published: 33 (100.0%). Sparse indicators are declared in the Data quality section of each indicator.
