Is accountancy a route into Banking & Finance roles later down the line?

I know it might be an obvious answer of: yes, but it depends on what you do within 'accountancy', but I'm asking since I want to know if I should consider Economics at uni, or just do A&F then ACA.

The reason I'm leaning toward A&F is because I have 3 work experiences in the field, including one at PwC, and strong PS material etc, unlike for economics, where everything is much weaker – I know you can't directly get 'economics' work experience and that PwC work xp is related, it's more that it is just *weaker* than applying directly for A&F.

So, I am going to be going for 5 A&F-related applications at uni, hopefully going for ACA (or similar) after, but wanted to confirm 1. whether B&F is even an option if I take this route and 2. If it is the right call dropping economics as a choice at uni

I know this has turned into a slightly more complicated question but I'd appreciate if someone just picked up on the main parts of it.
