Rate Change Tracker

Select a currency pair and time period to track rate changes

The Rate Change Tracker shows how a currency pair has moved over a specific period. Here's what each metric means:

Percentage change — How much the rate has moved from the start to the end of the period. Positive means the target currency strengthened.
Period high/low — The highest and lowest rates during the period. The gap between them shows the range of movement.
Average — The arithmetic mean of all daily rates in the period. Useful as a benchmark for "typical" value.
Volatility — The standard deviation of daily rate changes. Higher volatility means more unpredictable movements.

All data comes from ECB reference rates. Weekends and EU holidays are excluded from the calculation.

Compare the 7-day and 90-day views for the same pair. If the 7-day change is much larger than the 90-day change, the currency is currently in a strong short-term trend.

Understanding Currency Rate Changes: What the Numbers Mean

Exchange rates are constantly in motion, but not all movements are equally significant. The Rate Change Tracker on Tixya helps you put currency movements into perspective by showing you exactly how much a pair has moved over a defined period — and whether that movement is normal, unusual, or historically significant. Understanding the statistics behind rate changes is essential for anyone who deals with foreign currencies, whether you are sending money abroad, planning a trip, or managing international business finances.

What Counts as a "Big" Change?

In the foreign exchange market, the significance of a rate change depends entirely on the timeframe and the currency pair. For major pairs like EUR/USD, a 0.5% daily move is considered notable — it usually means a central bank made an announcement or major economic data was released. Over a 7-day period, a 1-2% move is significant. Over 30 days, anything above 3-4% suggests a meaningful trend shift. Over 90 days, a 5%+ move is substantial enough that businesses and investors might change their behavior — hedging strategies, timing of transfers, or pricing adjustments.

Understanding Volatility

Volatility measures how much a rate bounces around. A currency pair with low volatility (like USD/CHF, which often moves less than 0.3% per day) is relatively predictable. A pair with high volatility (like USD/TRY or USD/ZAR, which can move 1-3% in a single day) is much harder to predict. High volatility means there is more risk — and potentially more opportunity — when converting currencies. The tracker calculates volatility as the standard deviation of daily percentage changes, which is the same metric used by professional forex traders and quantitative analysts.

Using the Tracker for Real Decisions

Timing a transfer — If you need to send money abroad, check the 30-day trend. If the rate is near its 30-day high, it might be a good time to convert. If it's near the low, you might want to wait.
Evaluating a deal — If your supplier quotes a price in a foreign currency, check how much the rate has moved in 90 days. If it has moved 5% against you, your effective cost has increased significantly even though the quoted price hasn't changed.
Travel budgeting — Before a trip, check the 30-day trend for your destination currency. If it has been strengthening against your home currency, budget a bit extra to account for potential further movement.
Investment research — Currency movements directly affect international investment returns. A 10% gain in a foreign stock is wiped out if the currency weakens 10% against your home currency in the same period.

Limitations

The tracker uses ECB reference rates, which are published once per business day. This means intraday movements are not captured — only the daily closing reference rate. For most practical purposes, this is sufficient: the daily ECB rate is the fairest available benchmark. However, if you need to track intraday movements for trading purposes, you would need a real-time market data feed from a broker or financial data provider. Additionally, the ECB covers approximately 30 major currencies, so some emerging market currencies are not available in this dataset.
