[SMM Analysis] Off-Season Impact Evident Grain-Oriented Silicon Steel Prices to Trend Weakly with Fluctuations in August

July Price Review：

Domestic grain-oriented silicon steel prices rose first and then retreated in July. Supported by rigid demand from downstream transformer manufacturers as well as orders in the new energy and UHV sectors from early to mid-July, mainstream grades including B23R085 climbed to cyclical highs. Nevertheless, persistently high prices suppressed downstream purchasing willingness, market trading turned sluggish, and spot prices came under pressure and fell at month-end, ending the upward rally. In view of forward expectations, the market generally holds the view that this round of price surge has come to an end.

Fundamental Analysis

Domestic steel mills plan to maintain roughly the same output of grain-oriented silicon steel in August as in July, sustaining high production levels with no obvious tightening in supply delivery pace. In terms of product mix, production is still overwhelmingly dominated by high magnetic induction (HIB) grain-oriented silicon steel, while the output proportion of conventional CGO grain-oriented silicon steel remains low. Output of both varieties changes little compared with July. Steel mills have no intention of carrying out concentrated voluntary production cuts. The continuously ample supply keeps weighing on the spot market and creates obvious resistance to further price hikes.

Newly added installed capacity of various power sources showed divergent performance in June, forming structural support for grain-oriented silicon steel demand. Newly installed thermal power capacity maintained relatively strong year-on-year growth. Thermal power supporting step-up transformers and auxiliary transformers for power plants continued to generate rigid demand for grain-oriented silicon steel. Newly installed hydropower capacity increased substantially, driving demand for main and auxiliary transformers of hydropower stations. Newly installed wind and solar power capacity was weaker than the same period of previous years, leading to limited incremental demand for box transformers and main transformers supporting new energy. Newly installed nuclear power capacity declined, resulting in periodic weakening of demand for special grain-oriented silicon steel for nuclear power applications.

Overall, construction of traditional power sources gained momentum in June. Thermal and hydropower installed capacity contributed major incremental demand, supporting orders for large power transformers and further boosting demand for high-grade grain-oriented silicon steel. Insufficient incremental wind and solar power installations offset part of the demand growth. Therefore, demand presented a structural pattern: strong demand from traditional power sources and weak demand from the new energy sector.

August Price Outlook

Looking ahead to August 2026:

On the supply side, domestic supply of grain-oriented silicon steel will edge down slightly. Major state-owned steel mills will basically continue high-load production, while some private enterprises will conduct minor maintenance, leaving overall supply broadly stable. Despite the price correction of grain-oriented silicon steel in July, most steel mills still enjoy decent profits. In addition, leading steel mills including Baowu lifted the August base price of grain-oriented silicon steel by RMB 50 per tonne, demonstrating obvious price-support sentiment and sound overall production enthusiasm. Deliveries of high-grade products remain steady; however, sufficient supply of conventional grades has brought inventory pressure to the market.

On the demand side, China’s 15th Five-Year Plan UHV projects keep being launched. Transformer enterprises prioritize fulfilling supporting orders for UHV construction, and demand for high-grade grain-oriented silicon steel used in transformers for new energy grid interconnection stays resilient. Nevertheless, the impact of the high-temperature off-season will surface in August. Most downstream enterprises will only conduct inventory replenishment for rigid demand. The conversion of tender orders issued by State Grid and China Southern Power Grid is subject to time lags, and enterprises lack motivation for proactive stockpiling. Furthermore, India’s ongoing anti-dumping investigation against Chinese grain-oriented silicon steel has disrupted exports. Cargo diverted from overseas markets flows back and continuously hits the domestic market, putting prices under pressure.

On the cost side, hot rolled coil prices are expected to fluctuate weakly in August with limited upward momentum, and the monthly average price will continue to decline month-on-month.

In summary, SMM forecasts that grain-oriented silicon steel prices will fluctuate on a weak trend in August 2026. High-grade grades will be relatively resilient against price falls, while conventional grades will face more prominent downward pressure.
