Critical Minerals Market August 2026: Refractory Metals Correct as Precious Metals Rebound

By Peter Daniels — August 4, 2026

The critical minerals market August 2026 update is defined by a sharp reversal from July’s pattern: platinum, palladium and silver — all down double digits last month — have rebounded together, while several of July’s strongest gainers among the refractory and technology metals have corrected just as sharply. Antimony, tungsten and tantalum each fell more than 15% on the month, with antimony’s roughly 31.5% China-domestic decline the largest single move across all 30 metals CMN now tracks. Rare earths (NdPr oxide) pulled back below the US Department of Defense’s policy-supported $110/kg price floor for the first time referenced on this site. Layered on top: a fresh US Presidential Determination targeting recoverable critical minerals, a persistent sulphuric acid supply crunch tightening processing economics across several battery-metal supply chains, and continued structural tightness in DRC cobalt exports. This monthly roundup summarises price action across all 30 metals now tracked on CMN — up from 28 in July, following the addition of Alumina and Bismuth pages — with links through to the full price tracker for each.

Refractory and Technology Metals

What’s Driving the Market This Month

Refractory Metals Reverse Sharply — Domestic China Falling Faster Than the West

The standout move this cycle is the correction in antimony, tungsten and tantalum — three of July’s strongest gainers, now among August’s steepest losers. In each case, the pattern is consistent: China-domestic benchmarks have fallen far more sharply than Western/export reference prices. Antimony’s China-domestic 99.65% Sb benchmark fell roughly 31.5% while the European assessment eased a more modest 7.6%; tungsten’s APT China-domestic figure fell roughly 24.6% against a broadly steady CIF Rotterdam reference; tantalum pentoxide fell around 18.4% domestically while FOB export, powder and ingot pricing moved only 1.5–2.8%. Independent market commentary on both antimony and tungsten specifically describes this as the domestic and export markets “fragmenting” — a genuine bifurcation rather than a single global correction, consistent with what CMN’s individual trackers found this cycle. See the antimony, tungsten and tantalum price trackers for full detail.

Precious Metals Rebound After July’s Correction

Platinum, palladium and silver — which fell in double digits together in July — have each recovered this month, rising 2–5% depending on the metal. The rebound tracks easing Middle East tensions following renewed US-Iran diplomatic engagement and a softer US dollar after Japanese currency intervention. The synchronised nature of the move, both down in July and up in August, continues to point toward a shared macro driver across the three metals rather than three independent stories.

Domestic-International Base Metal Gaps Narrow

Several base metals that showed unusually wide domestic/international spreads in July — copper, zinc, aluminium — saw those gaps narrow this month as both benchmarks rose together rather than diverging further. Copper’s China-domestic premium over COMEX narrowed from roughly 15% in July to roughly 10% in August; zinc’s domestic premium over LME narrowed from around $103/tonne to roughly $38/tonne. This is a healthier signal than July’s widening divergence, though whether it continues converging or re-widens remains worth tracking into September.

Nickel Rallies on Fresh Indonesian Export Disruption

Nickel rose roughly 6.7% domestically and 5.9% internationally after Indonesian authorities increased inspections of mixed hydroxide precipitate (MHP) shipments over possible rare-earth content, prompting Tsingshan Holding Group — the world’s largest nickel producer — to suspend some export loadings. This is the third distinct Indonesian-linked supply shock of 2026, following April’s cost-floor revision and the Middle East sulphur disruption, underscoring how central Indonesian policy and logistics have become to global nickel pricing.

Lithium Corrects on Chinese Tax Policy and Mine Restarts

Lithium carbonate fell roughly 12% this cycle after China announced it will end tax exemptions for lithium-ion batteries, aimed at curbing a “race to the bottom” between manufacturers who had been increasing production schedules ahead of the policy change. Supply-side, CATL’s Jianxiawo lepidolite mine cleared security permits to resume operations after a prolonged suspension, while Australia’s Mineral Resources restarted its Bald Hill mine after 18 months offline and Core Lithium restarted its Finniss project — a genuine turn from the supply discipline that characterised 2025 toward renewed volume growth.

Rare Earths Fall Below the DoD Price Floor

NdPr oxide fell roughly 11.9% this cycle, reversing most of July’s 22% recovery and moving below the US Department of Defense’s $110/kg policy-supported price floor under the MP Materials contract for the first time referenced on CMN. Whether this level begins to act as a genuine market anchor — or the correction extends further — is one of the more interesting questions heading into September, since it’s the clearest real-world test yet of whether that policy floor matters for broader market sentiment.

Sulphuric Acid Crunch Continues to Pressure Processing Costs

The sulphuric acid supply disruption tied to the Strait of Hormuz conflict — first flagged by Benchmark Mineral Intelligence in late May — remains an active cost pressure across the battery-metals complex. Sulphur prices have climbed more than 50% since the conflict began, with sulphuric acid prices more than doubling in some regions; Benchmark estimates over half of global lithium, cobalt, rare earth and purified phosphoric acid refining capacity scheduled for 2026 is exposed to the disruption. High-purity manganese sulphate, used in EV batteries, is entirely dependent on sulphuric acid supply. This remains a live, ongoing risk factor rather than a new August development, but it continues to underpin elevated processing costs across several of the metals tracked above.

DRC Cobalt Quotas Keep Squeezing Intermediate Supply, Even as Headline Prices Ease

Cobalt’s headline China-domestic price fell roughly 9.5% this cycle, but the upstream picture tells a different story. The DRC’s 2026–2027 export quota system caps annual exports at 96,600 tonnes — roughly half of 2024 production levels — and CMN’s own cobalt sulphate tracker this month recorded cobalt hydroxide payable falling from 99.5% to 92% while the hydroxide processing fee rose, both signals of continued tightness at the intermediate stage even as finished cobalt sulphate pricing eased. This divergence between falling headline prices and tightening upstream feedstock is worth watching closely into September.

Policy and Geopolitical Developments

US Presidential Determination Targets Recoverable Critical Minerals

On 30 July 2026, the US President signed a Presidential Determination under Section 101 of the Defense Production Act, authorising the Secretary of Commerce to restrict exports of “recoverable critical minerals and materials” — defined to include black mass from spent lithium-ion batteries, end-of-life rare-earth permanent magnets, manufacturing swarf, and other scrap containing critical minerals. Copper scrap is explicitly excluded, since it’s already covered under a separate July 2025 proclamation. The determination doesn’t itself impose specific export bans — it establishes the legal authority for Commerce to do so — but it marks a clear policy shift toward treating recycled and end-of-life material as a strategic domestic resource rather than an ordinary export commodity, extending the same logic already applied to raw ore and primary production. For CMN’s readers tracking the NdPr and dysprosium/terbium supply chain specifically, this is a genuine new development worth monitoring for follow-on Commerce Department rulemaking.

DRC Cobalt Export Quota System Remains in Force

The DRC’s cobalt export quota framework — in effect since October 2025 following an earlier full export ban — continues to structurally constrain global cobalt supply through 2026 and 2027. The 96,600-tonne annual ceiling represents roughly half of the country’s 2024 production of over 200,000 tonnes, and reporting has flagged a persistent gap between allocated quotas and actual export clearances due to logistics and customs bottlenecks. This remains the single most important structural factor in global cobalt supply and is reflected in this month’s cobalt hydroxide payable and processing-fee data covered above.

What to Watch in September 2026

Three threads carry into next month. First, whether the antimony, tungsten and tantalum corrections stabilise or extend further — and whether the domestic/international “fragmentation” pattern seen across all three this cycle persists as a structural feature of Chinese export-controlled metals markets generally. Second, whether rare earths hold below the $110/kg DoD price floor or recover back above it — a genuine test of that policy level’s market relevance. Third, how Commerce Department rulemaking following the 30 July Presidential Determination develops, and whether specific export restrictions on recoverable CMMs move from legal authority to implementation.
