Scrap iron will increase in price after May Day. According to the analysis of China Iron and Steel Industry Association, due to the superposition of international commodity prices, loose global liquidity, rising market expectations and other factors, steel prices in the domestic market rose sharply after the May Day holiday, so scrap iron prices will rise after the May Day holiday. Scrap iron is a common processed product with high price. As a futures product, scrap iron belongs to consumables, and all kinds of manufacturing and construction are inseparable from it, which is also the reason for the price increase of scrap iron after May Day.
