(10)PSPs located in a Member State whose currency is not the euro could have limited access to liquidity in euro outside of business hours. Therefore, it is proportionate to provide for the possibility that such PSPs request the prior permission of their competent authorities to provide the payment service of sending instant credit transfers from accounts denominated in the national currency of that Member State outside of business hours only up to a certain limit per transaction. Competent authorities should be able to grant such permission based on their assessment of a PSP’s access to liquidity in euro.
