Mumbai is the political and administrative capital of India and Bangalore the centre of the important high-tech industry. However, Mumbai’s position as the country’s financial capital remains undisputed.

The city is also an important centre for many other industries and for foreign trade. Mumbai’s position as the financial capital of India is based on the dominance of its two stock exchanges – the NSE and the smaller BSE – and the power of its banking sector. Together, the two stock exchanges tower above all the other local Indian exchanges, in terms of market capitalisation and turnover. Meanwhile the city’s commercial and retail banking centre is also the largest in India. The service sector attracts the lion’s share of Mumbai’s incoming foreign investment. Also pre-eminent as a trading centre, pearls and precious and semi-precious stones are by far the largest single category (by value) of both import and export goods handled by Mumbai. Of the other principal industries, the cotton and textile business and machine engineering are probably the most important. Between them, these two sectors employ a third of the workforce of the city and account for a sixth of the export trade.

Perhaps the industry that Mumbai is most famous for, however, is Bollywood, which churns out about half of the 800 or so films made each year in India – Hollywood, by comparison, produces about 250 films a year. Reliable statistics are hard to come by, as the industry is notoriously shadowy – the majority of Indian films are financed through the black economy – and is not officially recognised. Best estimates suggest that the Indian film industry turns over the equivalent of £135 million a year.
