When RMB depreciates, futures will rise, because RMB devaluation means that money is oversupplied, which means that prices will rise, natural commodity prices will rise, and commodity prices, that is, futures prices, will naturally rise. Commodity futures prices correspond to raw materials, and raw material prices correspond to the costs of upstream enterprises. The price increase is only an increase in the cost of upstream enterprises. Whether it can spread to the middle and lower reaches and then to the consumer side is another matter. At present, the upstream enterprise is a seller's market, the price is relatively monopolized, and the cost is easily passed on to the middle and lower reaches. But there is no monopoly in the middle and lower reaches, and the consumer side is likely to be the buyer's market.
