【SMM Building Materials Inventory: Supply Stabilizes, Demand Continues to Recover, Inventory Continues to Decline】This week, the total rebar inventory was 7.6427 million mt, down 171,900 mt MoM, a decrease of 2.2% (previous value: -2.02%), and down 3.1523 million mt YoY compared to the same period last year, a decrease of 29.2% (previous value: -31.26%).

This week, the total national rebar inventory continued to destock, with a larger decline in wire rod inventory. The total rebar inventory decreased by 2.2% MoM, while the total wire rod inventory decreased by 8.06% MoM. This week, there was an increase in market news about production restrictions, and the annual production reduction has not yet been clearly implemented. Some steel mills announced upgrades to rolling lines, reducing construction steel production. The futures market saw a significant rally, and spot market prices and volumes both rose. The total inventory of construction steel continued to decline this week.

Looking ahead, some blast furnace steel mills in north-west and south-west China are currently underperforming, while blast furnace steel mills in other regions still maintain some profitability and continue normal production. EAF steel mills in central and east China have slightly reduced operating hours due to profitability and raw material procurement issues. As of March 25, the operating rate of SMM's 50 sample EAF steel mills was 39.68%, down 0.5% MoM. Overall, the production of construction materials is expected to remain stable. On the demand side, downstream end-user projects are affected by poor funding, and the recovery of demand intensity is lower than market expectations. The overall market sentiment remains cautious. During the spot price increase, merchants mainly focused on selling, limiting the upward potential. Looking ahead, the overall supply of construction steel is expected to remain stable, and although demand recovery is slow, it can still maintain the destocking pace. However, the destocking range is unlikely to expand significantly in the short term.

Before the holiday, the black chain is unlikely to see a trend-driven market [SMM Steel Industry Chain Weekly Report].

This week, ferrous metals were in the doldrums, with coking coal and coke staging a mid-week rise. At the beginning of the week, financial markets experienced sharp fluctuations, dragging down sentiment in the ferrous chain and leading to a pullback in futures. Mid-week, Indonesia's cut to coke production quotas drove coking coal and coke futures to lead the gains, though the impact was more pronounced on thermal coal, while coking coal's rise was largely sentiment-driven and short-lived. In the latter part of the week, finished products continued their seasonal inventory buildup, and support from the raw material side weakened, causing the entire ferrous chain to pull back. In the spot market, with the Chinese New Year holiday approaching, purchasing activity slowed down further, with end-users only making limited, as-needed purchases at low prices.
