Currency Strength Meter

30-day momentum of all 7 majors against the USD, computed from daily ECB reference rates. Positive = strengthening, negative = weakening. Data through 2026-08-28.

AUD +3.67%

NZD +2.96%

JPY +2.51%

EUR +2.31%

GBP +2.21%

CHF +1.96%

CAD +1.81%

Methodology: ECB daily reference rates (EUR-based, via Frankfurter, free) → converted to a USD base → each currency's USD cross constructed (EURUSD = 1/R(EUR); USDJPY = R(JPY); etc.) → 30-calendar-day momentum = % change of the USD cross. A rising EURUSD means the EUR is strengthening; a falling USDJPY means the JPY is strengthening. Reference rates are informational, not transaction prices.

How To Trade The Strength Meter

The classic pair-trade: buy the strongest currency against the weakest. If AUD reads +1.1% and JPY reads −1.3%, AUDJPY carries the strongest directional bias on the board. Confirm with the correlation matrix to avoid taking three trades that are really one position.

Strength is momentum, not valuation — a strong currency can be overextended. Use it as a bias filter for entries, not as a signal by itself.

FAQ

What does the currency strength meter measure?

The percentage change of each currency against the USD over the last 30 calendar days, using daily ECB reference rates. It captures momentum and interest-rate differentials, not intraday flow.

How often is the data updated?

ECB reference rates publish every working day around 16:00 CET; the meter refreshes its cache every 6 hours.

Is the currency strength meter free?

Yes — free, no signup, no API key. The same data powers our free calculators and historical data library.
