On Tuesday, March white sugar settled up 60 cents to $345.40 per tonne, compared with $390.90 a tonne, a year ago.
"It's not really a shocking statement, only because we know the margins are terrible in sugar," one US trader said.
Olam, which owns two sugar mills in India and crushes more than 1 million tonnes of sugarcane, is the latest sugar trading company to have scaled back or sold businesses.
In late November, Biosev SA, the sugar and ethanol maker controlled by trading firm Louis Dreyfus Co, hired an investment bank to seek potential buyers for some or all of its plants in Brazil.
Biosev had retained a unit of Dutch bank Rabobank to explore opportunities for its nine production units in Brazil's center-south region, the country's main sugar producing region, a source told Reuters at the time.
