Brazil's stocks fall; real weakens on global slump

SAO PAULO, Sept 5 (Reuters) - Brazilian stocks fell for a sixth day on Friday and the currency tumbled as concerns grew that a slowdown in the United States and Europe will cut demand for commodities and reduce capital flows to emerging markets.

The Bovespa index .BVSP of the Sao Paulo Stock Exchange fell 1.3 percent to 50,740.3 points, extending a market rout that has wiped about 10 percent of market value.

The slump in Brazil, where more than half of the index is linked to the metals and mining sector, followed a decline of 5 percent in copper prices and a drop in crude oil prices. Data on Friday showed the U.S. jobless rate rose to a five-year high, pushing Wall Street lower and adding pressure on Brazilian markets.

"Today, much like yesterday, we are at the mercy of the markets abroad," said Hamilton Moreira, senior investment analyst at BB Investimentos. "There is no sign of a recovery any time soon, given the data that came out this week."

Brazil's real BRBY weakened about 1.5 percent to 1.743 per U.S. dollar, after it sank 2.3 percent the previous session.

Interest-rate futures <0#DIJ:> on the BM&F commodities and futures exchange rose, reflecting the slump in global markets and the downturn in Brazil's exchange rate and equities.

On the stock exchange, state-run Petrobras (PETR4.SA: Quote, Profile, Research) dropped 2.4 percent to 30.7 reais as crude prices fell about 2 percent in New York and London.

Mining company Vale (VALE5.SA: Quote, Profile, Research) was down 1.2 percent to 35.09 reais, weighed down by a slump in copper prices on concerns about weak demand for metals and higher inventories. (Reporting by Elzio Barreto and Rodolfo Barbosa; Editing by Leslie Adler)
