Why do banks shy away from APIs?

Question

API

Good day to all!
I've always wondered why banks are so diligent about avoiding APIs? Why don't they want to develop on the Internet?
For example, the simplest opportunity to transfer money from your account to another (both accounts in the same bank). Even the introduction of just one such method could solve a lot of problems, make the world a better place and make many people happy. Not to mention that it will attract additional customers.
What caused this alienation from the IT world? Do banks bear any risks or losses from the convenience of interacting with them? Or maybe I'm wrong and this is already being actively used?

Answer 2

Banks are conservative bureaucratized machines with the slogan "work - do not touch." Not only do banks see no significant prospects in this, but management does not want to get between the rolls for creating new vulnerabilities.
The banking world is full of old school people. In one interview, I saw a man talking about a woman in senior management. He told her about "a bank is a business", and she "a bank is a bank, not speculation." Well, how can you retrain them when people think that "everything is invented and you don't have to play too much"?
In fact, there are banks with APIs, but they rather confirm the rule.

Answer 3

I think that all the funds that the bank provides for financial management undergo serious certification, and they are afraid to trust third-party applications to work with banking.

Answer 4

Well, in Promsvyazbank, this is due to the low qualification of the it division.
They can’t write a client-bank normally, a lot of bugs that they are not going to fix.
I updated Java, so their division stopped working altogether.
At the same time, the cost of maintenance is extremely inhumane: 20,400 rubles. for maintaining an account per year + fees for transfers.
