Major tin producers' plans to cut production have improved the outlook for tin and will likely lead to a supply deficit in the market next year, Macquarie Bank analyst Adam Rowley said. A recent Macquarie report forecasts a deficit of at least 5,000 metric tons next year, and a small surplus of 1,000 tons this year. Last year, the tin market surplus was 11,800 tons. "Concentrates availability will be a difficult issue for other Asian producers - there simply are not many producers with concentrates to sell," Rowley said.
