Honestly, I always thought Economics is one of the more interesting finance-related courses out there that can make you climb pretty high.
It would probably be better if you could do a double major or double degree in Econs & Finance. Might widen your job prospects especially in the banking industry. This way you won't be limited to just investment/analytical jobs.
I'll share a bit on my relatives: I have 3 cousins who did degrees in economics..

Cousin 1: Econs from Cambridge U (he's UK citizen). Got jobs at big investment companies the moment he graduated - JP Morgan, Lehman Bros, Goldman Sachs. Climbed pretty fast and earning lots.
Cousin 2: Econs (Hons) from UniWA (M'sian citizen). Got jobs at banks around Malaysia, but not as successful as the 1st cousin. Still surviving pretty well.
Cousin 3: Econs & Finance double degree from ANU (S'pore citizen). 1st job at Credit Suisse bank. Doing very well too...
This may imply that you'll more opportunities overseas. But I think you should do well in Malaysia too as long as you're good at what you do, just like any other job out there.
My POV is an outsider's POV. I'm from a totally different background (science)..
