Generally, small change in rate will not affect most much when planning for a trip. Put it this way, an increase in 0.1 baht against SGD fetch you an additional 100 baht only if you are changing SGD1000. Well how many bros gonna change SGD1k for a short trip assuming air tickets and hotels already settled in Singapore prior to departure?
Of course when comparing to 2002 when SGD fetch 24 baht and above, we lose in excess of 2k baht base on changing SGD1k compare to now but then again, that is if we knew….
