[SMM Operating Rate of Steel Mills Using Externally Purchased Billets] According to the SMM survey, as of March 31, the operating rate of steel mills using externally purchased billets mainly producing construction steel stood at 27.39%, up 27.39 percentage points MoM from February and up 5.25 percentage points YoY.

National construction steel prices fluctuated downward in March. Rebar prices reached 3,167 yuan/mt on March 23, the highest price of the month, and 3,131 yuan/mt on March 4, the lowest price of the month. After the Lantern Festival, downstream construction sites gradually resumed work, market demand gradually improved, and end-users' just-in-time procurement increased slightly.

Cost side, affected by multiple macro factors, the coal market as a whole showed a pattern of being more likely to rise than fall. At some coal mines in producing areas, production release was hindered by factors such as working face replacements, leading to a slight contraction in supply, while downstream procurement demand remained robust. Auction transaction premiums were obvious, further supporting stronger coal prices. As cost pressure was passed on, coke enterprises showed a strong willingness to hold prices firm, and expectations for a new round of coke price increases to be implemented heated up, which will likely be gradually realized in the near term. Raw material prices are expected to fluctuate upward in the short term, and cost support for steel remained in place.

Supply side, blast furnace steel mills currently maintained a stable production pace, with production remaining relatively steady; EAF steel mills resumed production in an orderly manner as planned, and the capacity utilization rate continued to rebound. As of March 24, the operating rate of 50 electric furnace steel mills nationwide mainly producing construction steel was 40.42%, up 1.78% from the previous period. Billet-rolling mills also gradually resumed work after the Lantern Festival, and the operating rate of steel mills using externally purchased billets was 27.39% this month, up 27.39% MoM, driving a rapid increase in overall market supply.

Demand side, downstream construction sites were gradually resuming work, and market demand increased somewhat. However, dragged down by end-user steel consumption volumes and tight cash flow at end-user enterprises, the market remained cautious about the outlook. Downstream construction sites and traders mainly purchased as needed, and the strength of demand recovery was weaker than in the same period in previous years.

Overall, after the Lantern Festival, both supply and demand increased, and the supply-demand imbalance was not yet prominent. As temperatures gradually recover and terminal construction conditions improve, the rebar supply-demand pattern is expected to improve mildly, and inventory is likely to continue declining. However, constrained by funding conditions, the room for incremental demand should not be viewed overly optimistically. Therefore, the increase in the operating rate of billet-processing enterprises in April is expected to be limited, and the room for overall supply growth is relatively small.

[SMM Iron & Steel] India Records 7.7% Growth in Steel Output Amid Global Decline

The World Steel Association reported on March 25, 2026, that while global crude steel production fell by 2.2% in February, India’s production surged by 7.7% year-on-year to reach 13.6 million tonnes. This growth is driven by the government's aggressive infrastructure spending and the "Make in India" initiative, which has bolstered domestic steel consumption. The increase in Indian output helps offset production declines in Russia and South America, as the country moves toward its national goal of 300 million tonnes of annual capacity by 2030.

GOES is a critical high-value component used in the manufacturing of power transformers and electrical equipment essential for the continent's energy transition. The investigation aims to determine whether imported products are being sold at unfairly low prices that damage European domestic producers and follows a broader trend of increased trade defense measures as the EU implements the Carbon Border Adjustment Mechanism (CBAM) this year.
