Having bank transfers in 2019 so slow is outrageous. It's the time when trading bots produce millions in a split second. But bank transactions require hours and days. And they dare to call them fast!

Eh, when does it really matter? The only time I care about speed is when buying something, and the more expensive that something is, the less fast it needs to be.

If you have a truck waiting to load at a warehouse somewhere waiting for your £200k payment to clear, then yes, the speed really really matters.

Same goes for aircraft. Good luck chartering an airliner at short notice without making a large deposit.

the orders might only take a few ms from creation to execution, but the settlement still takes time (hours to days)

2h is quick. In EU sometimes it can take days.
