Sugar futures prices saw a surge of over 1% on the New York and London stock exchanges on Thursday afternoon. The increase is attributed to support from oil prices, exchange rate fluctuations, and concerns about the Indian crop. The most significant rise was seen in raw sugar on the New York Stock Exchange, which increased by 1.96% in the main contract. The adjustments in the sugar market are also influenced by the decision mills make on sugar and ethanol production based on profitability, which is affected by the fluctuating oil market.
