The NPC One-Leg Out Instant Credit Transfer Scheme (NOLO Inst) is a set of rules, practices and standards to achieve interoperability for the provision and operation of international instant credit transfers where at least one leg of the transaction is in an NPC scheme currency (SEK, DKK or NOK). The scheme governs the NPC leg of such transactions and supports both One-Leg Out transactions — where only one of the parties holds a payment account at an NPC-based PSP — and Two Legs-In transactions, where both parties are NPC-based but the transaction involves currency conversion between two NPC scheme currencies, for example SEK to DKK.
NPC has obtained a licence from EPC to base the NOLO Inst Rulebook on EPC's One-Leg Out Instant Credit Transfer (OCT Inst) Rulebook. The two schemes are closely aligned wherever possible. The NOLO Inst scheme extends OCT Inst where Nordic-specific requirements apply, including currency-specific maximum amounts, national governance requirements, and the Two Legs-In transaction type, which is not covered by OCT Inst.
All NPC members and stakeholders are encouraged to provide feedback between March 15, and June 11, 2026, on the draft to be introduced as the first version of the rulebook. The public consultation is held to ensure that the payment schemes reflect the needs and evolution of the payment market, NPC’s members, and their customers.
Take part in the public consultation by using the response template and send it to info@npcouncil.org by June 11, 2026, at 17h00 CEST at the latest. The NPC will not consider any feedback received after this deadline.
In addition to the Rulebook, there can be local market practices, additional agreements and documentation from Clearing and Settlement Mechanisms (CSMs), technology suppliers or other relevant parties.
Connected to the Rulebook, there will be number of key documents which support the scheme operationally. These documents will not be presented as part of the public consultation but will be ready in time for publication and in-effect in November 2026.
· Guidelines regarding the Inter-PSP messages for the NPC leg (NOLO Inst Scheme Inter-PSP Implementation Guidelines
· Guidelines regarding the customer-to-PSP messages (NCT Inst Scheme Customer-to-PSP Implementation Guidelines), which each NPC leg-based Payer's PSP is recommended to support at the request of the Payer:
Please note that the actual date when transactions can be made according to the Rulebook will depend on when the adherents and the Clearing and Settlement Mechanisms (CSMs) are ready to process payments according to the scheme rules.
