Faster Payments Service (FPS)
FPS is a UK banking initiative to reduce payment times. It is focused on smaller payments and is subject to limits that depend on the individual banks. Transfer time, while expected to be short, is not guaranteed and will depend on the payment institutions and banks involved.

Single Euro Payments Area (SEPA):
SEPA is a payment-integration initiative of the European Union and is used for sending cross-border Euro deposits and withdrawals between banks that are part of the SEPA network.
SCT Instant:
SEPA Instant Credit Transfer (SCT Inst) was first launched in November 2017 across the EU as an optional Payment scheme for banks to participate in. If your bank supports SCT Inst, you can send funds to and from your Kraken account within minutes.
These types of payments incur banking charges, so please contact your bank to enquire about fees, as well as their cut-off times. The current maximum limit for SCT Inst is €100,000.00 per transaction. This is a limit set by the SCT Instant network and is outside of Kraken's control.
