It has been implied Monzo won’t do their own SEPA, SWIFT etc payments but connect to Transferwise thru the marketplace.
At the moment SEPA Credit Transfers (SCT) take some time to be sent, however an instant 24/7/365 payment scheme named SCTinst is scheduled to be implemented by November 2017. This will allow real time payments 24 hours a day and 365 days a year (within 10seconds).
Will Monzo be offering SCTinst thru any 3rd party?
