SAO PAULO, Oct 24 (Reuters) - A decline in Brazilian cattle prices this year and strong demand for the country's beef exports will widen Brazilian meatpackers' margins in the short term, according to analysts, though weakness in the domestic market could undercut those gains. "The margins of slaughterhouses that export has improved," said Alcides Torres, director of Scot Consultoria. Beef prices in Brazil have been dropping on the back of a higher number of cattle coming to market as well as the more aggressive negotiating stances adopted by foreign buyers, especially China. A weaker yuan currency has pushed China, which accounted for almost 53% of Brazilian beef purchases in September, to press for discounts from sellers in the South American nation, Safras & Mercado analyst Fernando Iglesias said. Brazil's beef exports in October have already surpassed those from the same month in 2021, according to government data.
