Not sure how it is in other banks or large companies, but at BNYM, promotions can actually be a trap. In late 2020, my manager and I got promoted. I would manage the team I'm on and he would manage the other teams that worked along side us (I would still report to him though).
Despite not having any managerial experience, my new management responsibilities began within the next month or so. Because of the timing, though, I couldn't see a raise until 9 months later. And it was only about 10K. I don't blame my manager or his manager, but it just speaks to how BNYM will really try to milk you for everything you're worth.
My manager got a really raw deal. He had to wait OVER a year for the new pay and title to kick in, but by that point, our reporting structure changed and we were moved to a different division. He even got a new manager so it was like there was a good chance he might not have gotten the raise at all. And his responsibilities really expanded - until office politics phased him out because this new manager brought in a bunch of expensive duds.
Meanwhile, individual contributors were getting promoted to my grade despite not having any managerial duties.
If I was smart enough to realize the carrot BNYM dangled in front of me wasn't a great prize, I could've left earlier and seen a bigger pay raise immediately, one I never would've seen at BNYM.
I realize things are bad across the company all around (I still have many good friends here), but even if things are working a little better for you and you are offered a promotion, I believe you can do better elsewhere.
