Affected by insufficient demand, the transaction has been tepid, and the daily turnover is basically below tons. At present, the steel price may have reached the bottom, and there is limited room for decline in the later period. The future price may still be dominated by maintaining stability. Affected by the fact that Bagang has delivered less resources recently, some local specifications are out of stock, and businesses are also reluctant to sell. However, the overall structural adjustment pressure of the steel industry is obvious, and there are downside risks to economic growth. In addition, the overall performance of the manufacturing industry is still relatively sluggish, and the price policy of first-line steel mills in October also maintained a stable but declining tone. At present, the overall fundamentals of the steel market remain negative. Near the end of the month, the pressure of the grouting pipe steel traders to withdraw funds and the tightening tone of the central bank&#;s monetary policy kept the overall liquidity tight. In addition, and there will not be much reversal in the short term. From the performance of the internal and external markets we still need to be vigilant about the hot-rolled market, the game between the long and short sides is prominent, and the short side increases the price, which makes the iron ore market rise and touch the wall.
