"In early July 2025, PayPal notified Valve that their acquiring bank for payment transactions in certain currencies was immediately terminating the processing of any transactions related to Steam. This affects Steam purchases using PayPal in currencies other than EUR, CAD, GBP, JPY, AUD and USD," the message states.
"We hope to offer PayPal as an option for these currencies in the future but the timeline is uncertain.
There are currency conversion services all over the world that manage to do this. How hard can it possibly be to partner with an existing service to do the conversion as part of a transaction?
EDIT: I guess it's possible to do the conversion yourself and have a bank account in one of those currencies to use to do PayPal, so the practical impact is probably limited, but still. PayPal's whole point is to facilitate moving funds from Point A to Point B. You've got one job here, guys.
Based on the screenshot someone else posted, they do have some kind of payment/currency system of their own, Steam Wallet.
I guess you could buy a physical Steam gift card in a store via any mechanism the store accepts, including cash, and then transfer it to that.
