Hello,

IBPS conduct the exam and any person who want to apply must possess a graduation degree in any 

discipline/stream from a recognised university by Government of India.

There is no necessity of a specific degree for applying point of view but if you

consider for the job then a  degree in commerce or in Economics is suitable.

so,out of these B.com is the best option to become a government bank manager.  

Hope it helps.

Thank you
