Unsurprisingly, there is a not a huge demand for currency exchange when foreigners are not allowed into a country. While Thailand is gradually re-opening, most currency exchanges have not. Beware of this if you need to exchange money in Bangkok.
Currency Exchange in Bangkok
I made the mistake of leaving my ATM card at home on my trip to Bangkok last month. While I can usually get by fine with just my credit card, several of the coffee shops I visited required cash or debit card for payment and would not accept a credit card.
Faced with the prospect of drinking bad coffee, I promptly elected to exchange some USD for THB.
Small problem though: as I walked through the city every single currency exchange bureau I came to was out-of-business or closed.
I spent over an hour walking around before I finally found one inside a tailor shop. After exchanging my money, I let the guy know he could probably charge a bit of a premium because he was the only currency exchange shop that was open…
Granted, this was on a Saturday, but it was in the middle of the day.
Later, I found one other place near the Grand Hyatt Erawan that was open..but most places were closed.
I usually avoid exchanging money altogether but when I do I certainly avoid exchanging it at the airport, where the rate is rarely as good. Here, it would have been easier to exchange money at the airport and you should consider doing so.
Bangkok is a bit behind other East Asian cities in being able to tap everywhere for credit card payment. Expect to pay cash at many places, particularly if not a chain.
I was surprised at how few currency exchange bureaus were open in Bangkok. Most were closed, many permanently. While they will likely return when tourists return, be sure to bring your ATM card or exchange in advance before journeying to Thailand.
