Jinrui futures believes that there are three reasons for the rapid rise of nickel. First, the dominant inventory is extremely low, the domestic social inventory is low, and the import loss leads to the limited inflow of imported goods into the domestic market, and the LME inventory is less than 654.38+10,000 tons.

Second, the domestic pre-holiday reserve demand, especially the increase in new energy-related production capacity in June 5438+ 10, made the spot and the premium in recent months stronger. Third, the main contract with high positions and low warehouse receipts (LME warehouse receipts are highly concentrated) triggered a forced callback. Trading unit * Minimum fluctuation price = 1 ton/hand * 10 yuan/ton = 10 yuan/hand, which means that the primary fluctuation of Shanghai-tin futures is 10 yuan.

It can be seen that the fluctuation range of Shanghai-tin futures is an integer multiple of the minimum fluctuation price.
