Update July 2017
ALL arms in Thailand now charge 250thb service charge (a prob £5.20) for using a foreign card. No exceptions. Example: you ask to withdraw 1000thb. Machine will notify you of the charge. Your transaction will be billed at 1250 then withdrawn. This is the greedy Thai banks not Monzo. This is a service fee not exchange fee. Most arms will ask you if you want to use the dynamic exchange rate. DON’T. This rate is set by the atm owner and is typically 3% less than monzo. Remember that this is in addition to the 250thb charge. Unfortunately Thai banks are hammering tourists and expat like me. Some arms will now decline your transaction if you select no to the dynamic conversion. If this happens, go to another banks atm. Unfortunately, more and more arms are doing this. It doesn’t matter what card you use. My advice is take plenty of cash with you and avoid arms. No fees if you use your card in shops, but again make sure you are charged in thb and not sterling. Some shops point of sale machines are set to home currency by default rather than local currency.
