Mumbai has traditionally owed its prosperity largely to its textile mills and its seaport till the 1980s. These are now mostly replaced by industries employing more skilled labour such as engineering, diamond polishing, healthcare pharmaceutical marketing and information technology. Mumbai is also the primary financial centre for India, both the major Indian stock exchanges (BSE and The National Stock Exchange), brokerages, asset management companies (including majority of the mutual fund companies), headquarters of most Indian state-owned and commercial banks, as well as the financial & monetary regulatory authorities of India (SEBI and RBI among other institutions).
