Generally speaking, if you remit local or domestic currency, such as USD to a US bank account, Singapore dollars to a Singapore bank account, 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 from the country or region, such as Singapore dollars to a US bank account, US dollars to a Singapore bank account, 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 if they receive local currency. For example, if you remit US dollars to US Wise, Wise will charge a handling fee of 10 US dollars per transaction. So if you want to receive a specific amount, it is recommended to remit local or domestic currency and avoid banks like Wise, so that you can receive a specific amount.
Or it is recommended that you remit an extra thirty to fifty dollars when remitting to cover the cost loss in the process, so that the amount you receive will not be lower than your expected amount.
