"MYR is considered to be a restricted currency, which implies an inherent limitation to the tradability of this currency. Fund transfers in this currency are not allowed outside of Malaysia"

Lets say you work in Malaysia; your salary is paid in MYR as its legally required to be. You can't get a bank account with most banks because US passport - therefore you can't get a MYR bank account.
