This might be a future competition for bitcoin's instant worldwide payment feature
If banks use their specially designed blockchain to do the international settlement, then real time payment will be achieved. They will make sure their own blockchain will be powered by their special algorithm and their own mining farms around the world, so basically no confirmation is needed for any transaction
Each customer will pay with their domestic currency, they don't even see the bank's blockchain running in the background. The problem is, banks have to handle the conversion to/from their own crypto currency on both ends, that will bring lots of comlexity, makes it even more complex than today's sytem, where they only need to convert currency once
Another hard part is to find enough banking partners in each region. In sweden, swish mobile payment is a real time payment network, it works because all 7 major swedish banks are connected to this system. Even some of the small swedish banks are not connected to the system, you can imagine, it will be very difficult to find enough international banking partners for using blockchain to do transaction (And that will cause lots of bank employee to lose their job, thus face harsh resistance)
Even banks successfully did this after many years, they just built a transaction network, that still won't provide anti-inflation promise of bitcoin, so it won't threaten bitcoin's position as long term saving medium
