Euro at 1.1591 USD on June 17, 2026: Official exchange rates for businesses

Key data

If your company invoices, purchases or settles in dollars, pounds, yen or Swiss francs, the exchange rate you must apply on June 17, 2026 is already fixed. The Resolution from the Bank of Spain published in the BOE on June 18, 2026 establishes the official euro exchange rates set by the European Central Bank for that date. These rates have official status under Article 36 of Law 46/1998 and are the mandatory reference for commercial, accounting and tax operations.

What does this regulation establish?

The Bank of Spain publishes daily, in accordance with Article 36 of Law 46/1998, the exchange rates that the European Central Bank sets for the euro against the main world currencies. These rates are the only ones with official status in Spain for operations that legally require an accredited exchange rate reference.

The rates published for June 17, 2026 are as follows:

These exchange rates are mandatory reference for commercial operations, accounting entries and tax operations requiring currency conversion, as well as for customs settlements. They are not negotiable rates: they are the legal reference that prevails in case of discrepancy or inspection.

Economic and operational impact

Using an exchange rate different from the official one in accounting records or tax declarations can generate unjustified exchange differences, which exposes the company to adjustments in inspections by the Tax Agency or Customs. The three areas of direct impact are:

• Accounting: Exchange differences between the transaction rate and the official rate at closing must be recorded in accordance with the General Accounting Plan. The June 17 rate is the reference for operations on that day.
• Taxation: Currency operations declared in Corporate Income Tax or VAT must be converted to euros using the official rate in effect on the accrual date.
• Customs: Tariff settlements for imports or exports processed on June 17, 2026 use these rates to calculate the customs value in euros.

The relative strength of the euro against the dollar (1.1591 USD per euro) means that companies exporting to the US receive fewer euros for each dollar collected, while importers from the US pay fewer euros for their dollar purchases. The rate against the pound (0.86463 GBP) is particularly relevant for companies with operations in post-Brexit United Kingdom.

Who does it affect?

• Exporting companies that invoice in USD, GBP, JPY or CHF and must convert income to euros in their accounting records.
• Importing companies that pay suppliers in foreign currencies and need to value the cost in euros for accounting and customs.
• Finance departments and CFOs that close currency positions or calculate exchange rate hedges.
• Tax and accounting advisors that prepare Corporate Income Tax or VAT declarations with foreign currency operations.
• Foreign trade operators and customs agents that process import or export declarations dated June 17, 2026.
• Financial entities that use the official rate as a reference in products or contracts linked to the ECB rate.

Practical example

A Spanish company imports machinery from the United States for a value of 500,000 USD. The invoice is dated June 17, 2026. To record the operation in accounting and for customs settlement, it must convert the amount to euros using the official rate of the day:

500,000 USD ÷ 1.1591 = 431,369.16 EUR

If the company had used a different exchange rate, for example 1.15 USD (more favorable), the recorded value would be 434,782.61 EUR, a difference of more than 3,400 EUR that could be questioned in a customs or tax inspection. Using the official rate published in the BOE is the only way to prove correct valuation.

Similarly, an exporting company that collects an invoice of 100,000 GBP that day must record the income as 100,000 ÷ 0.86463 = 115,659.48 EUR.

What should companies do now?

1. Verify all currency operations on June 17, 2026: Identify invoices issued or received in USD, GBP, JPY or CHF with that date and ensure that the conversion to euros uses the official published rates.
2. Update accounting records: If the ERP or accounting system applies automatic exchange rates, check that the June 17 rate matches the official values (1.1591 USD; 185.82 JPY; 0.86463 GBP; 0.9193 CHF).
3. Review customs declarations: Imports and exports processed on June 17 must reflect the customs value calculated with these rates. Coordinate with your customs agent if there are declarations pending correction.
4. Document the source of the applied rate: Keep the link to the BOE resolution as documentary support for possible requests from the Tax Agency or Customs.
5. Calculate pending exchange differences: If you have collections or payments in currencies that will be settled on later dates, record the difference between the rate of the original transaction and the settlement rate in accordance with applicable accounting regulations.
