Thanks for the clarification. Really informative.
Regarding transactions in THB, I read from the FAQs:
“For a few illiquid currencies, we provide the best rate we possibly can. For THB […], we apply a small 1.5% markup on the exchange rate.”
“At the weekend (Friday 23:59 - Sunday 23:59) we apply a small mark up on the spot rate as the Forex markets are closed. We take the rate from Friday 23:59 and apply a 0.5% mark up on major currencies and 1.0% on other currencies to protect the company from potential losses due to a large fluctuation in the rate. For illiquid currencies like Russian Ruble and Thai Baht, there is 1.5% mark up on weekend”
Does it mean that if I buy in THB I will be normally be charged 1.5% extra on weekdays and 3% extra (1.5%+1.5%) on weekends or just always 1.5% for THB?
Are those starting times for the weekend UK time or local Thailand times?
