Gotrade News - US copper futures premiums widened sharply ahead of a June 30 Commerce Department tariff assessment that could trigger 15% duties from January 2027. Comex front-month copper traded more than $500 per ton above London Metal Exchange spot prices, the widest spread since last autumn.
The tariff countdown coincided with China's State Council unveiling sweeping outbound investment rules effective July 1, 2026. The dual policy moves tightened global capital flows in copper supply chains and cross-border technology deals simultaneously this week.
Key Takeaways
- Comex copper trades above a $500 per ton premium to LME as traders front-run a potential June 30 US tariff decision.
- China's State Council will require approval for sensitive overseas investments starting July 1, expanding Beijing's authority over cross-border tech deals.
- Speculative copper long positions hit a twenty-week high, with JPMorgan projecting 2026 average prices near $12,500 per ton.
According to TradingKey, more than 30,000 tons of copper at the New Orleans LME warehouse were marked for withdrawal on May 22. Combined canceled warrants across LME facilities exceeded 50,000 tons that day, a magnitude rarely seen in over a decade.
LME copper futures briefly touched $13,746 per ton on May 29, representing roughly 43% gains across twelve months. An all-time record above $14,500 was recorded back in January 2026.
Copper Inventory Shift And Tariff Mechanics
The White House amended Section 232 on April 2, retaxing copper derivatives based on total product valuation rather than raw material weight. The Department of Commerce must deliver its copper market assessment to President Trump by June 30, a critical decision deadline.
Previous Commerce recommendations suggested a 15% refined copper tariff starting January 1, 2027, increasing to 30% from January 1, 2028. Industry executives expect monthly US copper imports could rebound to 150,000 to 200,000 tons during the arbitrage window.
Comex-approved warehouse inventories surged from roughly 80,000 tons in February 2025 to 577,385 tons, representing more than 550% growth. That stockpile now accounts for 44% of global exchange copper inventories, with LME stocks falling substantially over the same period.
World Bureau of Metal Statistics data shows US refined copper imports doubled year-over-year in early 2026, reaching 533,000 tons. Producers including Freeport-McMoRan (FCX) and Southern Copper (SCCO) stand to benefit from sustained import demand if tariffs proceed.
Goldman Sachs cautioned that recent breaches above $11,000 per ton reflect expectations of future supply tightness rather than current fundamentals. JPMorgan Chase projects average 2026 copper prices near $12,500 per ton while keeping its full-year target above $13,000.
China Outbound Rules And Tech Spillover
As reported by Investing.com, China's State Council announced expanded oversight of overseas investments effective July 1, 2026. The rules formalise Beijing's authority to force unwinding of completed cross-border deals in sensitive sectors.
The measures followed Beijing's directive last month requiring Meta Platforms (META) to divest its acquisition of AI startup Manus. Manus had earlier shifted employees to Singapore, the kind of indirect transfer the new framework now explicitly targets.
The regulations require authorization for export of restricted Chinese goods, technologies, services, or associated data. They also prohibit indirect knowledge transfer mechanisms, including overseas deployment of technical staff and cross-border talent transfers in sensitive sectors.
Per Crypto Briefing, the policy aligns with the Made in China 2025 initiative prioritising domestic innovation over foreign ventures. The rules compound February 2026 limitations on offshore token issuance connected to domestic assets.
Meta shares declined 0.44% during the reporting period, signalling investor concern about intensified Chinese restrictions on foreign technology investments. Investors and companies have until July 1 to prepare for compliance with the enhanced capital flow and technology transfer requirements.
