Extended data:

The domestic steel market as a whole fluctuated and declined, among which the outstanding talents declined obviously.

The steel market has entered the off-season of demand, the construction of high-temperature and rainy projects has been blocked, the summer break of manufacturing industry has increased, and the demand has dropped significantly; Steel futures are weak and difficult to change, hitting a new low since listing in 2009; The price of imported iron ore has fallen sharply, the cost support of steel mills has weakened, and steel prices have continued to fall;

In the middle and late period, with the RRR cut by the central bank and the introduction of fine-tuning stimulus policies, the macro positive news boosted steel prices, and the decline in the spot market slowed down.

By the 24th, the price of tertiary rebar in Shandong Province was 3040-3060 yuan/ton, down 160 yuan/ton from the end of last month; The price of thick coil is 3300-3350 yuan/ton, down from the end of last month 10 yuan/ton; The price of medium plate is 3340-3400 yuan/ton, down 40-50 yuan/ton from the end of last month;

The price of small and medium-sized H-beams is 3080-3 1 10 yuan/ton, and the price of ordinary large H-beams is 3030-3060 yuan/ton, down 70- 100 yuan/ton from the end of last month; The price of 45# steel is 3360-3380 yuan/ton, down by 90 yuan/ton from the end of last month.

Leading indicators of economic operation: the industrial added value and PMI rebounded slightly in May, and the year-on-year decline of PPI narrowed, but whether the real economy really bottomed out remains to be confirmed;

The downward pressure on real estate is great, the growth rate of steel demand slows down, and it is difficult to improve in the later period; The improvement of profitability of steel mills promotes the recovery of production. In the first half of June, the output of crude steel reached a new high, and the supply pressure was still severe. The social inventory of steel decreased for the 16th consecutive week, but the destocking speed slowed down. Imported ore fell below the previous low and fluctuated slightly around $90/ton;

Leading steel mills are cautious about the market outlook, and prices are stable and declining; It is expected that the domestic steel market will form a bottom shape in July.
