US bank offering best currency exchange rate

Does anyone know which bank in US offers the best currency exchange rate to Portugal.


Many use to transfer and exchange larger amounts.
Transferwise for smaller amounts.


Hi . What would be a smaller amount ? . I purchased a house for 125k with Wise . Effortlessly

For GV, up tp 550k or more needs to be transferred, so OFX has a slightly better rate for larger amounts. Scrutiny is quite extensive of course.
