I. Market Review
Over the past two days, the main soda ash futures contract (SA2701) has shown a pattern of rising and then falling back; prices retreated from a recent high near 1,020 yuan/tonne to around 1,050 yuan/tonne. Trading volume saw a slight, continuous decline, indicating a weakening of rebound momentum. This price action suggests that the bullish sentiment—driven by production cuts due to maintenance and real estate policies—is being rapidly absorbed by the reality of high inventory levels, causing the market to refocus on supply-demand fundamentals. On the spot market front, data shows that the market price for heavy soda ash in the Shahe region was 996 yuan/tonne on September 3, down 24 yuan/tonne from 1,020 yuan/tonne on September 1; spot trading activity was lackluster, with downstream buyers primarily restocking to meet immediate needs.
II. Analysis of Driving Factors
(i) Supply Side: Increased Maintenance and Plummeting Output Lead to Short-Term Marginal Supply Contraction
Supply contracted significantly this week. For the week ending September 3, domestic soda ash production totaled 718,800 tonnes—a sharp week-on-week drop of 47,400 tonnes (6.19%) and a year-on-year decline of 4.38%. The capacity utilization rate stood at 75.47%, down 4.97 percentage points from the previous week's operating rate of 80.44%. Regarding maintenance, units at Inner Mongolia Boyuan Yingen Chemical and Hangzhou Longshan underwent maintenance, while Henan Junhua experienced a brief shutdown; only Nanfang Alkali Industry recently resumed operations, meaning the bulk of production losses due to maintenance materialized this week. However, it is worth noting that the summer maintenance season is drawing to a close, and future maintenance plans are limited; the short-term drop in output is largely a periodic fluctuation. If units currently under maintenance resume operations, there is room for supply to recover, and the single-week drop in output is insufficient to reverse the overall pattern of loose supply-demand balance.
(ii) Demand Side: Weak Downstream Absorption and Declining Sales-to-Production Ratio
Weak demand remains the core factor suppressing soda ash valuations. This week, the production-to-sales ratio for soda ash stood at 94.63%, a decrease of 1.74 percentage points from the previous week. Remaining consistently below the 100% equilibrium mark, the rate of shipments lagged behind production, directly resulting in a continued accumulation of inventory. Regarding the two major downstream demand sectors: the operating rate for float glass was 67.19%, with a national daily melting capacity of 142,200 tons—figures largely unchanged from the previous period. However, given the industry's deep losses, expectations for cold repairs and production line retrofitting persist, offering limited support for "heavy" soda ash demand. Meanwhile, the operating rate for photovoltaic glass was only 48.14%; the high number of production line cold repairs acted as a drag on the marginal growth of heavy soda ash demand. Overall, the downstream landscape of low demand and low profit margins is unlikely to see substantial improvement in the short term, and the baseline demand for soda ash continues to drift downward.
(III) Inventory: Factory stocks have risen to high levels, with no sign of a turnaround yet
Inventory represents the heaviest source of pressure on the current soda ash market. According to Mysteel data, total domestic factory inventory reached 1.9113 million tons for the week ending September 3—an increase of 38,600 tons (2.06%) week-on-week and 4.90% year-on-year—placing it at a historical high for this time of year. A breakdown reveals that heavy soda ash inventory rose by 12,700 tons to 868,400 tons, while light soda ash inventory increased by 25,900 tons to 1.0429 million tons; thus, stocks for both grades accumulated simultaneously. Looking at recent trends, factory inventories have climbed for two consecutive weeks since late August—rising by 27,800 tons last week and another 38,600 tons this week. The pace of accumulation has accelerated rather than slowed, and a turning point toward inventory reduction has yet to materialize. Even more concerning is that inventory continued to build despite a 6.19% week-on-week drop in production; this indicates that the scale of production cuts is failing to keep pace with the rate of demand contraction, implying that further, more significant production reductions are required to narrow the supply-demand gap. (IV) Cost and Profit: Deep losses across both production processes; a tug-of-war between cost support and production cut expectations
The continued deterioration of profit margins is providing a floor for market prices. According to Mysteel data, for the week ending September 3, the production cost for heavy soda ash via the ammonia-soda process in North China was 1,373 yuan/tonne, with a gross profit of -243 yuan/tonne; meanwhile, the cost for the combined production process in East China was 1,277.5 yuan/tonne, with a gross profit of -227.5 yuan/tonne. Both mainstream processes are operating at deep losses, with the deficit for the ammonia-soda process widening further compared to the previous period. On the cost side, the recent continuous rise in coal prices has also provided a price floor for soda ash, serving as the primary driver for the market's earlier rebound. Deep losses typically compel enterprises to increase maintenance and accelerate capacity exit—a trend corroborated by current signs of increased maintenance activity. However, it is important to note that there has been no substantial exit of active capacity yet; the industry's process of spontaneous clearing through losses is slow, and cost support is reflected more in a slowing rate of price decline rather than a reversal of the overall trend.
III. Market Outlook
Overall, the soda ash market presents a classic scenario of conflicting bullish and bearish factors. On the bullish side, increased maintenance is driving a marginal contraction in supply; coupled with deep losses exceeding 200 yuan/tonne across both processes and rising coal costs, the price floor is relatively solid. On the bearish side, manufacturer inventories have accumulated to a historical high of 1.9113 million tonnes for this time of year, with social inventories rising in tandem; demand from downstream float glass and photovoltaic glass sectors remains weak, and the reality of oversupply has not been reversed by a single week of reduced production. In the short term, cost support and supply reductions due to maintenance may limit the downside for market prices, but the potential for a rebound is also constrained by high inventory levels; soda ash is expected to continue fluctuating at low levels while the market digests the oversupply issue, as the conditions for a trend-driven rally are not yet in place. In the medium term, whether the industry sees a turnaround depends on three key factors: the scale and duration of maintenance-related production cuts, whether there is a substantial exit of active capacity, and the impact of glass furnace cold repairs and changes in photovoltaic production lines on essential demand. Going forward, key factors to watch include the turning point in the destocking of manufacturer inventories, updates on plant maintenance, and coal price trends. (Source: Sina Finance)
