Masters Degree Advice

Sophomore Mathematical Finance major from a semi-target. I have a high GPA and think I can challenge myself by pursuing a Masters degree and graduate on time with two degrees. I like finance a lot but I think my undergrad degree gives me enough technical knowledge to work in IBD. Would a Masters in Finance really set me apart? Was thinking of a humanities-based Masters to enhance my speaking and communication skills. This would also show I'm well-rounded and not some numbers geek. (50% of my curriculum is comp sci and , math). I'm leaning towards a Masters in Policy & Innovation. Any advice is greatly appreciated. Thanks
