Bulgaria to join euro area on 1 January 2026

Also, the addition of Bulgaria means it's almost possible to travel from Spain to Greece entirely through the Eurozone, with only a thin sliver of Serbia or Macedonia in the way. (Assuming we include Montenegro and Kosovo in the Eurozone: technically they aren't, but for all practical purposes they are.)

It'll also be interesting to see who's next. Czechia is not far off but doesn't seem to be in a hurry, while Romania wants in but still seems to be a ways off. Poland and Hungary will stay outside unless there are major political changes.

My experiences in non-Euro, Schengen countries is that all payment terminals offer me the choice to pay in Euro or the local currency. In many cases in tourist areas (of Czechia, Poland, and Bulgaria) I only encountered terminals that asked for payment in Euro.

However, the benefits of a single currency go beyond cash. It's also about understanding prices. You see a sign for coffee and it's 1199 Hungarian Forint -- or it's 14.99 Polish złoty. It's not clear at all what those numbers mean. Sure it's possible to pull out a currency calculator app to see what the rate is today and what it means in euros. It's not an insurmountable problem, but it is bigger than a mere inconvenience. It's constant friction on not really understanding what's going on. If those coffee prices were instead 2.99 € vs 3.53 €, you would immediately see that the Polish coffee is 20% more expensive.

As for the payment terminals offering to pay in Euro, as others have already noted, that's a scam. There is a hidden fee, usually around 3.5% - 5.0% of your total, that you get charged for this "convenience". Refusing this and paying in the listed currency will mean that your own bank will do the conversion, which is basically always going to be far cheaper.

Unfortunately this currency conversion scam is so lucrative that even big brands engage in it. Amazon for example asks what currency your card is in. If you select some currency other than what this sepecific Amazon's listed prices are in, well, you're in for another juicy hidden fee, this time to Amazon.

Granted, I haven't recently been to any EU country without the Euro, but my main bank charges extortionate conversion fees, 2.sth%, with a ridiculous minimum per transaction.

A few months ago, I've ordered something off Amazon UK (while in the UK) and the conversion they offered was very close to the official GBP / EUR exchange rate, way below my bank's minimum. The price wasn't high, either, on the order of 10 €.
