At the policy level, the adjustment of trade policy has attracted widespread attention. Since June 4, US President Trump has significantly increased tariffs on steel and aluminum imports from 25% to 50%, aiming to boost domestic manufacturing and capacity utilization. This policy has hit EU steel exports to the United States. Although exports in April fell by only 13% year-on-year, as the policy is further implemented, it is expected that by July, EU exports to the United States will almost stagnate. The European Steel Association has put pressure on the European Commission to launch a stronger trade protection mechanism. In addition, the US Department of Commerce also plans to impose tariffs on "steel derivatives" from June 23. However, the tariff trade agreement reached between the United States and the United Kingdom has brought a slight change, with British steel companies receiving a preferential tariff rate of 25%.

In terms of market supply and demand, data from the China Iron and Steel Association showed that in early June 2025, key steel companies produced a total of 21.59 million tons of crude steel, with an average daily output of 2.159 million tons, a month-on-month increase of 3.2%; steel inventory was 15.79 million tons, an increase of 490,000 tons from the previous ten days, an increase of 3.2%. Last week, the number of production lines under maintenance at steel mills decreased, involving maintenance and resumption of production at steel mills in 9 provinces and cities. It is expected that maintenance and resumption of production this week will affect the recovery of production by 69,300 tons. In the raw material market, on June 13, the overall steel raw material market was stable but weak. Iron ore prices continued to weaken, with the 62% index falling by 0.55 to US$93.8/dry ton. The national main port iron ore transaction volume was 801,000 tons, a month-on-month decrease of 6.2%. The scrap steel market is clearly divided by regions. On June 13, 51 steel mills lowered their scrap steel purchase prices, and 8 raised them. On June 14, some steel mills in East China raised their prices by 30 yuan/ton, and steel mills in many places in Central China and North China lowered their prices by 10-20 yuan/ton.

There are also major events at the corporate level. On June 13, US President Trump formally approved Nippon Steel's acquisition of US Steel for $14.9 billion, a deal that may reshape the US steel industry. In addition, Nissan Motor Co. uses Nippon Steel's green steel NScarbolex Neutral for its mass-produced cars; international technology group Andritz has received an order from Olympic Steel of the United States to provide an innovative cut-to-length line for its plant in Minneapolis, Minnesota.

In summary, the global steel industry is in a critical period of policy adjustment, market fluctuations and corporate changes, and the subsequent development trend deserves continued attention.
