As part of our regulatory obligations under the Payment Services Act, there are limits to how much you can deposit in your Revolut account. The limits depend on whether or not you have set up an External Account. If you have set up your External Account, you can deposit more than S$5,000 or foreign currency equivalent throughout the day; at the end of the day (between 23:30 and 23:59), any balance over the regulatory limit of S$5,000 or foreign currency equivalent will be transferred automatically to your External Account.
If you do not have an External Account set up, you can only deposit up to S$4,800 or foreign currency equivalent. Attempts to top-up beyond this will be unsuccessful until you reduce your account balance or set up an External Account.
