　　More than ten days after the May Day holiday, most steel varieties surged and broke historical records, with the average price per ton of steel for the eight major varieties exceeding 6600 yuan. On May 12th, it was emphasized to deal with the rapid rise in prices and its associated impact. This signal immediately caused a reaction in the market, and steel prices began to decline significantly, with the average price of various varieties in the market dropping by about a thousand yuan, basically falling back to the starting point before the sharp rise. During the interview, a steel mill insider told reporters that compared to the daily shipment volume of nearly 10000 tons during the price increase period, the recent shipment volume has significantly decreased, only two to three hundred tons.

　　Steel traders did not wait for the "golden September and silver October" before steel prices began to rapidly decline. Huang Kun told reporters that the black market has experienced a significant decline since late October, and there has been no expected oversold rebound since then. Instead, it has further declined. At the end of October and the beginning of November, some of the reverse jackets were priced at 400-700 yuan/ton. More than ten traders in the Tangshan market have already sold out, and the situation is similar in other distribution centers. Many long-term delivery times are concentrated between November 15th and November 30th. If the basis continues to widen before November 15th, most futures trading companies and traders will face the risk of huge losses or even liquidation. At this time, the interests of the side that is being hedged will reach a consensus. If the market cannot rise, then the only way to promote the convergence of the basis is to lower the price.

　　An industry insider told reporters that in the first half of this year, steel traders benefited from policy dividends and earned a lot of money. Starting from October, some traders may experience some losses from high priced goods in the early stages, but overall, there should be a slight profit for the whole year. At present, steel traders are generally facing difficulties, high capital costs, inadequate settlement prices, and inverted losses. Terminal manufacturers have a strong voice and demand cost reduction every year. The rise in raw material prices has led to heavy cost reduction tasks and high payment pressure for them, "said Huang Kun.
