ECB euro reference exchange rate on September 30: 1.1355 US dollars
Impact level
⚪ Background
What happened
The European Central Bank published a euro–US dollar reference exchange rate of 1 euro = 1.1355 US dollars for 2026-09-30. This is the ECB’s official daily reference rate, used as a benchmark for euro area currency conversions. The data reflects only the exchange rate level for a single day; the source provides no change, historical comparison, or policy statement. [1]
Seller impact
- InferenceA single official reference rate is not enough to determine whether the euro strengthened or weakened, nor to infer its actual impact on euro area sellers’ pricing, settlement, or cash flow; comparison with the previous day’s or an earlier official reference rate is needed. [1]
Suggested action
Verify whether the exchange rate used for settlement or pricing cites that day’s official ECB reference rate, to avoid using a third-party quote by mistake.
Evidence that would disprove the assessment
- Assessment 1:This assessment should be revised if a subsequently published ECB reference rate for the previous day indicates a directional change, or if related policy information on euro area interest rates, inflation, or other matters emerges.
