When it comes to bank exchanges for euros, Bank of China provides certain limits for individual customers. Specifically, the maximum amount of euro equivalents that each customer can redeem per year is $50,000. This amount needs to be reserved before exchange, and applies to the total of personal foreign exchange settlement and domestic foreign exchange purchases. According to Article 2 of the "Implementation Rules of Individual Foreign Exchange Management Measures", the total annual exchange amount is set according to individual needs, and the annual total amount per person is fixed at US$50,000. The State Administration of Foreign Exchange has the right to adjust this limit based on the balance of payments to meet the needs of the economic situation.

It is worth noting that this amount is for an individual’s total annual redemption, which means that within a year, no matter how many times it is redeemed, the total does not exceed US$50,000. If more than this amount is required, customers may need to meet certain conditions or wait for a limit adjustment. In general, Bank of China's euro exchange services are limited and closely related to foreign exchange management policies. Therefore, when performing exchanges, it is best to consult the bank in advance and understand the latest exchange policies.
