Copper Prices Near Record High in August 2026: Supply Deficit Widens

Copper prices are surging to near-record levels in August 2026, driven by a powerful combination of weakening U.S. dollar sentiment, tightening global supply, and robust demand from the renewable energy and AI data center sectors. LME three-month copper closed at $14,185 per ton on Friday, marking eight consecutive weekly gains and sitting just steps away from the all-time high of $14,527.50 per ton. For copper buyers and industry professionals, understanding the forces behind this rally is essential for making informed purchasing decisions.

The global copper market entered the second half of August with prices firmly entrenched in historically elevated territory. Here's a snapshot of key price benchmarks as of August 24, 2026:

The LME copper market continues to maintain a backwardation structure, with the cash-to-three-month premium holding above $60 per ton - a clear signal of persistent tightness in immediately available supply. Although LME registered warehouse stocks saw a brief 19.43% jump on August 18, total inventory remains at just 23,860 tons, well within historical lows. Meanwhile, Shanghai Futures Exchange (SHFE) copper inventories have dropped to 4.61 million tons, the lowest level in recent years, further constraining domestic availability in the world's largest copper-consuming nation.

1. Weakening U.S. Dollar and Fed Rate Cut Expectations

The U.S. Treasury's "short-for-long" bond swap - effectively a stealth Yield Curve Control (YCC) operation - has capped long-end Treasury yields and undermined confidence in the dollar's long-term trajectory. As the dollar weakens, dollar-denominated copper becomes more affordable for buyers using other currencies, naturally boosting global demand. Market expectations of Federal Reserve rate cuts add further upward momentum, with the upcoming Jackson Hole central banking symposium at the end of August serving as a critical near-term catalyst.

2. Historic Supply Tightness at the Mine Level

Perhaps the most fundamental driver is the unprecedented squeeze at the supply source. The copper concentrate treatment charge (TC) has plunged to -$176 per dry ton - a historic low that means smelters are effectively paying mines to take their concentrate rather than earning processing fees. Chilean copper mines have reported production disruptions from natural disasters, while Chinese smelters face mounting losses, triggering maintenance shutdown expectations that will further constrain refined copper output.

This supply compression is not cyclical - it reflects declining ore grades across mature mining districts and insufficient new mine projects coming online. Global copper mine growth has repeatedly fallen short of expectations, and the gap between mine output and smelting capacity is widening.

3. U.S. Copper Tariff Looming

With the September 30 deadline for a potential U.S. presidential announcement on copper tariffs, the COMEX-LME price spread remains at $200–300 per ton. This persistent arbitrage window continues to draw physical copper toward U.S. warehouses, depleting available supply in the rest of the world and keeping non-U.S. markets structurally tight. Any tariff decision - whether confirmation or delay - will have immediate implications for global copper flows.

4. Structural Demand Growth from AI and Renewables

Copper demand from AI data centers, solar installations, energy storage systems, and electric vehicles now accounts for approximately 30% of total global copper consumption, up significantly from just a few years ago. BHP projects that global annual copper demand will grow from the current 34 million tons to 50 million tons by 2050, driven primarily by these emerging sectors.

This structural shift means copper demand is increasingly decoupled from traditional construction and real estate cycles. Even as property-linked copper demand softens, the AI and energy transition megatrend more than compensates, creating a durable demand floor.

UBS Wealth Management projects that the global copper market deficit will widen from 219,000 tons in 2026 to 379,000 tons in 2027, with a price target of $15,500 per ton.

BHP's latest fiscal year results revealed that copper has, for the first time in the company's history, surpassed iron ore as its largest profit source - a landmark shift that underscores copper's growing strategic importance to global mining majors.

Chinese domestic electrolytic copper social inventories remain at low levels, with spot premiums supporting futures prices. The recycled copper industry is undergoing regulatory normalization, which is tightening scrap supply and narrowing the price spread between refined and scrap copper - further reinforcing refined copper's premium position.

On the demand side, Chinese fiscal policy is shifting toward household consumption support, which could stimulate downstream copper product demand heading into the traditional "Golden September" manufacturing season.

Short-term: Copper prices are likely to remain in a high-volatility trading range. Key resistance for LME copper stands at $14,400 per ton, with support at $13,800. For SHFE copper, the trading range is approximately 105,500–110,000 yuan per ton. The Jackson Hole symposium at the end of August will be a critical watchpoint - a hawkish tone could trigger a dollar rebound and copper pullback, while dovish signals could fuel a push toward the record high.

Medium to long-term: The supply deficit driven by declining ore grades, insufficient new mine projects, and expanding renewable energy demand provides a solid fundamental foundation for sustained higher prices. Crucially, this rally is supply-shortage-driven, not a speculative bubble - the underlying scarcity is real and structural.

LME copper resistance: $14,400/ton

LME copper support: $13,800/ton

SHFE copper resistance: 110,000 yuan/ton

SHFE copper support: 105,500 yuan/ton

Key watchpoint: Jackson Hole symposium (late August)

For manufacturers and procurement teams sourcing copper tubes, plates, bars, wires, strips, and heat exchanger tubes, the current price environment calls for a disciplined, strategic approach:

Stagger purchases rather than chasing highs. Given the elevated price levels, avoid large single-lot purchases. Scale in at key support levels to average down costs and reduce timing risk.

Lock in long-term supplier agreements. Volatile markets reward strong supplier relationships. Secure pricing frameworks with trusted partners to mitigate spot market exposure and ensure supply continuity.

Monitor key catalysts. Watch the Jackson Hole symposium, U.S. CPI data releases, LME inventory movements, and any updates on the U.S. copper tariff timeline for optimal entry timing.

Consider recycled copper where specifications allow. The narrowing refined-scrap spread makes recycled copper a viable cost-saving option for non-critical applications, though availability remains constrained.

Plan for the "Golden September" demand pickup. As Chinese manufacturing activity typically accelerates in September, competition for available copper may intensify. Securing supply commitments ahead of this seasonal uptick is advisable.
