Instructing Bank

The result of a merger between Gringotts and Hogwarts.

Also, it’s a designation in bank transfers.

Your cousin sells you his collection of autographed Justin Timberlake memorabilia. It costs $2,000, which you plan to send him via wire transfer.

Your bank is the instructing bank here. It tells the other bank (known as the “advising bank”) all the details: your cousin’s name, the account number, the amount, etc. It provides instructions about where the money should go...hence, instructing bank.
