I don't think it's true that there's no consensus around how to programatically handle monetary values. Maybe there's no consensus around how to do it in JavaScript. In the Java world, there's JSR-354: https://jcp.org/en/jsr/detail?id=354 https://jcp.org/en/jsr/detail?id=354 Cobol has handled money well for decades. .NET has Decimal, which should handle money correctly as long as you're working with values less than 79.2 octillion. In my part of the world, at least, big banks tend to be mostly Java and Cobol on the back end. You'll definitely see Node, Go, and others being used for various tasks throughout the company, but when it comes to keeping track of money and moving it around, it's primarily Java and Cobol doing the heavy lifting. That's what I've heard from other developers, anyway. I haven't worked at a bank myself.
