Brazil stocks, currency slump on global worries

SAO PAULO, July 10 (Reuters) - Brazilian stocks and the real opened lower on Friday in line with U.S. markets as investors fretted over second-quarter U.S. earnings and the possibility of a slower than expected U.S. economic recovery.

The benchmark Bovespa index .BVSP was down 0.56 percent at 48,902.58 in choppy morning trading after a market holiday on Thursday, dragged down in part by a slump in oil and commodities prices.

The real (BRBY), Brazil's currency, was down around 1.3 percent at 2.02 per dollar as the greenback strengthened broadly against a global basket of currencies .DXY.

Investors remain skittish over the outlook for second-quarter corporate earnings in the United States.

Chevron Corp (CVX.N) said after the bell on Thursday that second-quarter earnings would be hit by a sharp decline in U.S. refining margins and that a weaker dollar would offset benefits from higher oil prices.

U.S. crude oil futures CLc1 dropped 1.1 percent on Friday, hitting the lowest level since mid-May, as the latest forecast from the International Energy Agency stirred more worries about oil demand. [nN10509187]

Shares of state-run oil company Petrobras (PETR4.SA) were down 0.17 percent at 29.06 reais after slumping in recent days amid a global decline in oil prices.

Brazilian miner Vale (VALE5.SA), the world's largest producer of iron ore, was down 1.31 percent at 27.80 reais as commodities slumped.

Vale this week raised $942 million from the sale of three-year notes convertible into stock at maturity. Petrobras and Vale are the stocks with the biggest weighting in the Bovespa.
