Sugar prices have increased due to the market's outlook of lower supply from India and Brazil. In Brazil, the sugar production in the Center-South region has decreased by 5.58% compared to the previous year, totaling 39.82 million tons. On the other hand, India's sugar production is expected to drop by 2.94% to 26.4 million tons by September. These factors have contributed to the rise in sugar prices on the New York and London stock exchanges.
