Investment banking assists individual clients, private companies and governments to raise capital by underwriting the issuance and sale of securities in the capital markets. An investment bank may also provide advisory services to companies involved in mergers and acquisitions, and other financial services to customers.
Generally investment banks require special licenses which do not permit simultaneous operating as commercial banks, ie attracting deposits. While most large investment banks and Offshore Bank Accounts provide services in all business lines, both buy-side and sell- side, smaller banks tend to focus, for example, on sell-side segments such as boutiques or small broker -dealers.
Corporate finance are the traditional business of investment banking. Most banks offer investment advisory services to the divisions and mergers and acquisitions. This may involve subscribing investors to a security issue, coordinating with bidders, or negotiating with companies that may or are facing a takeover bid.
