[SMM Coking Coal and Coke Daily Brief Review] In terms of supply, coking costs increased and losses widened somewhat. At present, coke producers were barely maintaining normal operating rates, while coke production remained temporarily stable. Meanwhile, downstream demand for coke increased, and coke producers' shipments improved somewhat. On the demand side, steel mills were in an active phase of resuming production, while finished steel prices fluctuated upward and steel mill profitability improved somewhat, boosting production enthusiasm and increasing demand for coke. In summary, the fundamentals of coke supply and demand developed in a positive direction, and the coke market may remain generally stable with slight rise in the short term.

[SMM Daily Brief Review of Coking Coal and Coke] In terms of supply, coking costs at coke producers increased, profit per mt of coke narrowed somewhat, and coke producer inventories still needed to be drawn down, weighing on their production enthusiasm. However, downstream demand improved somewhat, and coke producers were actively making shipments. Demand side, the country's important meetings have concluded, and blast furnaces previously subject to production restrictions resumed production one after another, increasing rigid demand for coke. However, uncertainty still remained in finished steel consumption, and most steel mills remained cautious in their coke procurement. In summary, the supply-demand imbalance in the coke market eased somewhat, and cost support strengthened. In the short term, the coke market may temporarily remain stable.

[Price Review] During the week, silver prices remained in the doldrums. In China, the Ag (T+D) contract on the Shanghai Gold Exchange broke below the support level of 18,000 yuan/kg, while LBMA silver prices kept probing lower after falling below $75/oz. From a macro perspective, escalating geopolitical conflict in the Middle East pushed oil prices to repeated new highs, while intensifying inflation concerns significantly cooled expectations for US Fed interest rate cuts and delayed the timing of the first cut to year-end. The simultaneous strength in the US dollar index and US Treasury yields became the core factors suppressing silver prices. On Wednesday local time, the US Fed announced that it would keep interest rates unchanged. In the statement released that day, it noted that the impact of the Middle East situation on the US economy remained uncertain and that uncertainty surrounding the US economic outlook was still elevated. In addition, speculative demand and ETF holdings continued to decline, and market sentiment kept cooling. As for the gold/silver ratio, because silver posted a deeper decline, the ratio continued to rise. As of March 18, the LBMA gold/silver ratio had climbed to 63, a recent high. [Important Data] Bullish: US preliminary March one-year inflation expectations came in at 3.4%, above expectations and unchanged from the previous reading Bearish: US API crude oil inventory for the week ended March 13 increased by 6.556 million barrels, above expectations and the previous reading US EIA crude oil inventory for the week ended March 13 increased by 6.156 million barrels, above expectations and the previous reading Data and macro releases to watch next week include: Continued hawkishness from the US Fed, the ECB rate decision, US inflation/employment data, COMEX silver delivery, together with the Boao Forum and geopolitical risks On March 19, the FOMC kept rates unchanged at 3.50%–3.75%, raised its 2026 PCE forecast to 2.7%, and expectations for US Fed interest rate cuts cooled sharply. US-Iran Situation: As of March 19, the military strikes by the US and Israel against Iran had entered their 19th day, with high-intensity confrontation, no sign of a ceasefire, and the conflict spreading to multiple Gulf countries. In terms of the current impact on precious metals, financial suppression outweighed safe-haven demand. Against the backdrop of surging inflation expectations, the US dollar and US Treasury yields continued to rise, the timing of US Fed interest rate cuts was delayed, and silver prices were suppressed. [Price Forecast] Silver prices are expected to maintain a fluctuating trend in the doldrums amid the interplay between macro disruptions and fundamentals. On the macro front, caution is still warranted over the risk of continued US dollar strength and heightened volatility from any further escalation in the US-Iran conflict. On the fundamentals side, as PV export rush orders gradually approached their end, rigid demand for raw material procurement by silver nitrate enterprises declined in late March, weakening support from industrial demand. In China's spot market, as investment demand and rigid industrial demand softened, coupled with replenishment from imported silver ingots, circulating supply of silver ingots in the spot market became ample, and suppliers generally lowered spot premium quotes to facilitate transactions. The abnormally high spot premiums in China's spot market will come to an end. At the same time, profitability on imported silver ingots will also decline sharply, and spot premium quotes in actual spot silver ingot transactions are expected to return to rational levels.

[SMM Daily Brief Review of Coking Coal and Coke] In terms of supply, as the Two Sessions ended, coke producers previously subject to production restrictions gradually resumed production. With losses per mt of coke remaining within an acceptable range, production enthusiasm was moderate, and coke supply increased steadily. On the demand side, as the country's important meetings ended, steel mills previously subject to production restrictions were expected to resume production, leading to some increase in coke demand. However, as no clearly positive policies emerged from the Two Sessions, market wait-and-see sentiment remained strong, and steel mills maintained a cautious attitude toward coke, mainly purchasing as needed. In summary, the coke market may remain temporarily stable in the short term.

Russia’s Solikamsk Magnesium Works recently launched industrialised production of magnesium alloys containing rare earth elements such as neodymium, cerium, and lanthanum. The products combine lightweight properties with high strength and are mainly targeted at sectors including aerospace and automotive manufacturing. The plant accounts for 100% of Russia’s rare earth compound production and 75% of its magnesium capacity, and this capacity expansion further consolidates its position in the strategic metals sector. Meanwhile, the “magnesium-based hydrogen slurry” technology developed by Germany’s Fraunhofer Institute has sparked controversy. Independent analysis indicated that the technology’s overall system efficiency is only about 10, its energy density is comparable to that of lithium batteries, its cost is far higher than expectations, and its recycling chain has yet to form a closed loop. It is only suitable for demonstration scenarios at the hundred-watt level and is unlikely to achieve commercial application. The two pieces of news reflect the different technological pathways and industrialisation prospects of magnesium-based materials in high-end manufacturing and energy storage.

This week (March 13, 2026–March 19, 2026), multiple enterprises in the solid-state battery sector were active: Dali Times commenced construction of a 2 GWh specialized semi-solid-state battery base; EVE’s Longquan Phase III/IV all-solid-state batteries rolled off the line in Chengdu; Chery released its 600 Wh/kg Rhino all-solid-state battery technology。

As a niche yet high-strategic rare metal, hafnium (Hf, atomic number 72) lags behind common metals like copper in public awareness, but its unique physicochemical properties make it irreplaceable for nuclear power, aerospace, semiconductors and other high-end fields. This concise breakdown covers its core traits, supply dynamics and critical applications to highlight its underrecognized role in advanced manufacturing. I. Core Properties A silver-gray, high-melting-point transition metal, hafnium exists solely as a zirconium-associated metal—no independent ore deposits. The near-identical atomic radius and chemical properties of zirconium and hafnium make separation/purification highly challenging, the root of its scarcity.Key strengths for harsh industrial use: 2233℃ melting point, exceptional high-temperature oxidation/structural stability Strong room-temperature plasticity, balanced strength and toughness Superior corrosion resistance (insoluble in dilute acids/alkalis, soluble only in hydrofluoric acid/aqua regia) ~600x higher thermal neutron absorption than zirconium (ideal for nuclear reactor control) High dielectric constant of hafnium oxide (critical for advanced semiconductors) Carbides/nitrides (melting point >2900℃) for ultra-high-temperature ceramics and hard alloys II. Supply & Scarcity Resources: Extremely scarce (crustal abundance ~3 ppm), exclusively tied to zirconium ores. Global resources concentrated in Australia, South Africa, the U.S. and Brazil; China faces low hafnium content in domestic zirconium ores, leading to high external dependence. Supply: Production hinges on zirconium smelting, with zirconium-hafnium separation as a core technical barrier. Only a handful of global players produce high-purity (nuclear/electronic-grade) hafnium at scale, forming an oligopoly. Annual output is ~hundreds of tons, with ultra-low supply elasticity—supply disruptions trigger sharp price swings. Ⅲ. Irreplaceable Core Applications Demand is rigid (no cost-effective substitutes) across high-end sectors: Nuclear Industry: Preferred material for pressurized water reactor control rods, regulating reaction rates and ensuring safety. Driven by global nuclear power revival, demand is steadily growing. Aerospace: Key nickel-based single-crystal superalloy additive, boosting high-temperature creep strength and lifespan for aero-engine turbine blades, combustors and rocket nozzles. Semiconductors: High-purity electronic-grade hafnium oxide overcomes silicon dioxide’s miniaturization limits, reducing leakage current and enabling advanced-node chip production—a key growth driver. Other High-End Fields: Used in cutting tool coatings, special electronic components, corrosion-resistant materials and emerging hydrogen storage research, with expanding use cases. Ⅳ. Conclusion Hafnium is a "scarce niche metal with rigid high-end demand," holding irreplaceable strategic value in China’s key industries (nuclear power, aerospace, semiconductors). The global market remains in long-term tight supply-demand balance, and its strategic and market value will rise alongside global advanced manufacturing upgrades.
