Generally speaking, if you remit the local or domestic currency, such as remitting US dollars to a US bank account, Singapore dollars to a Singapore bank account, or Hong Kong dollars to a Hong Kong bank account, the bank will not charge a handling fee; if you remit a currency that is not domestic or local, such as remitting Singapore dollars to a US bank account, US dollars to a Singapore bank account, or US dollars to a Hong Kong bank account, the bank will charge a handling fee, ranging from a few dollars to tens of dollars.
However, some banks will charge a handling fee even when receiving domestic currency. For example, if you remit US dollars to Wise in the United States, Wise will charge a handling fee of US$10 per transaction.
