Barchart - Sugar prices remain weak as they continued their week-long slide on Friday, with NY sugar falling to a 5-week low and London sugar posting a 4-week low. Signs of abundant global sugar supplies are weighing on prices. On Tuesday, India's Food Secretary said the government has no plans to ban sugar exports this year, easing concerns that it could divert more sugar to make ethanol following the Iran war disruption to crude oil supplies.
