The city is home to a solid
infrastructure with an important seaport, an international airport,
a domestic airport, two subway lines, several inter-municipal
railway lines, and a public transportation network of hundreds of
bus lines and thousands of buses.
Rio is the headquarter of
major private and state financial, telecommunication, and
entertainment companies. The recent discovery of oil in the Campos
basin resulted in Rio being the main base of several Brazilian and
foreign energy, oil, and gas companies. In fact, Brazil's subsalt
region, a huge deep-sea area of oil reserves under a thick layer of
salt, could hold up to 100 billion barrels - providing a huge demand
for rio-based services.
The city is a leading financial and
banking center, and Rio's investment activities include real estate
development, funds management, and the second largest stock market
in Brazil. Created in 1845, the Rio de Janeiro stock exchange, was
the first stock market to be established in Brazil, trading today
exclusively government securities.
