i am aware about RBI rules & policy for retail banking license .
what if someone wants to start only PURE INVESTMENT BANKING operation ?
what are basic requirements to start ?
govt. regulations , minimum capital on books , eligibility criteria for various positions in the bank etc ?
Investment bank offers various services like trading,research,Mergers & Acquisition,loan syndication,Asset management,custodian services,restructuring, corporate finance,underwriting and others.
If one entity offers various services under its umbrella it is called as investment bank.
To offer each service I-Bank has to get related approvals accordingly. So, it not like there is going to be one license to start Investment Bank.
