In a year, Spring Festival and Mid-Autumn Festival are the festivals that consume the most sugar in China. In 1 month before two holidays, due to the large amount of sugar used in the food industry, the consumption of sugar entered the peak period, and the sugar price was often higher during this period. After two festivals, the price of sugar tends to fall due to the decrease of sugar consumption. August and September are the peak periods of sugar consumption. Moon cakes, candied fruit in the north, drinks and biscuits all need sugar very much, which will stimulate the consumption of sugar. The corresponding sugar futures trading is relatively active.
