Research interpretation

The table answers a narrow operational question: which published reference observation is being used, in which unit, and how it differs from the preceding available date. A rate expressed per EUR must not be inverted or treated as a live broker quote without an explicit separate calculation and label.

Source and method

Source: European Central Bank. Original reference data is available free from the ECB. Informational reference rates, not executable quotes.

Original sample-source XML: https://www.ecb.europa.eu/stats/eurofxref/eurofxref-hist-90d.xml

All eighty sample values were matched by date and currency to the ECB current 90-day XML. Change is calculated as (latest / previous - 1) × 100. No rounding is applied to the displayed source values. The percentage calculation is an explicitly derived comparison, not an ECB forecast.

Limits

The source histories are current amended vintages. First historical availability is unknown; this report is not an as-of archive, a validated backtest, a forecast or a trading instruction. Missing publication dates remain absent. Browser/service retrieval time does not replace the economic observation date.

Reproduce
