Both of these degrees are undergraduate degrees and depending on the specialization you choose, have different effect on your CV when applying for a job in the banking sector.
For example, a candidate with a degree in B.Com (banking and insurance) will have an edge over a candidate that has a general B.Com or BBA degree as their course prepares them with a skillset made for the particular job sector.
However, a candidates performance in the interview rounds as well as their knowledge and understanding of banking might tip the scales in their favour as well.
Hope this information helps.
Best of luck!!
