A client earning USD and EUR touring fees is running a currency business whether they know it or not.
Most UK-based artists with meaningful US or European touring income receive a material share of their earnings in foreign currency. That money sits in a USD or EUR account (or gets converted at whatever rate the bank applies on the day it arrives) and no one thinks of it as an FX decision.
It is an FX decision. The difference between converting USD 45,000 at 1.20 and converting it at 1.26 is a £1,786 swing in GBP received. Over a year with four quarterly distributions, that is a £7,000 variance, more than a month's fixed costs for many clients, arising from nothing more than timing and inaction.
Hedging is not exotic. For a music business it means asking one question: is there a known, large, foreign-currency receipt coming in the next 90–180 days, and is the current rate acceptable? If yes, locking it in costs almost nothing. If the answer is no and the rate moves, the shortfall arrives with no warning and no remedy.
