Jan 16 (Reuters) - Brazilian stocks fell on Wednesday as bank losses weighed on the Bovespa index despite robust gains from the retail and materials sector, while currencies in Latin America weakened against the U.S. dollar. Sao Paulo's benchmark index fell 0.2 percent, further retreating from record-high levels as financial stocks sagged after the biggest U.S. banks blamed a bond market slump towards the end of 2018 for lower fixed-income revenues. Itau Unibanco Holding S.A led the declines among financials, while Brazilian planemaker Embraer SA lost the most on the index after it lowered its revenue projection for 2018, hurt by fewer deliveries of executive jets and a runway testing incident with a new jet. Embraer is in the midst of finalizing a deal with Boeing in which it expects to sell 80 percent of its commercial aviation division for $4.2 billion. Shares of Brazilian gun maker Taurus Armas SA, which does not trade on the benchmark, fell more than 10 percent after Brazil's government said it is contemplating opening the domestic market to foreigners. Among top gainers, oil marketing firm Cosan SA Industria e Comercio rose 2.5 percent and retailer Via Varejo was up 2.6 percent. The Bovespa has so far risen almost 7 percent since the beginning of the year, continuing a bull run after emerging as one of the top performing indexes across the world in 2018. Latin American currencies meanwhile, weakened as the dollar benefited from the euro's fall after the British parliament rejected Prime Minister Theresa May's Brexit deal. Brazil's real and Mexico's peso slid for a second consecutive session, while Chile's peso was one of the few currencies in the region to gain, buoyed by a rise in the price of copper, the country's main export.
