HG Copper: War, Tariffs, and a Market at the Edge of 6.15 Copper FuturesCOMEX_DL:HG1!EdgeClearGeopolitics, Policy, and the Forces Moving Copper Right Now The US-Iran conflict has shut down the Strait of Hormuz, collapsing global oil supply by 10.1 million barrels per day in March per the IEA, and the demand destruction from $150 crude is now weighing directly on copper's demand outlook. What is less discussed but arguably more significant for copper specifically is the sulfuric acid crisis the conflict has unleashed. Goldman Sachs flagged on April 21 that the near-total halt of Gulf tanker traffic has strangled global sulfur supply, a critical input for the solvent extraction and electrowinning process that accounts for 17% of global copper production. The DRC, where 50 to 60% of copper output depends on sulfuric acid, faces curtailments of approximately 125,000 tons if disruptions extend beyond late May. China compounded the problem by banning its own sulfuric acid exports effective May 1, putting around 200,000 tons of Chilean production at risk, given Chile sourced roughly a third of its acid from China in 2025. Codelco disclosed in March that the war had already pushed its copper production costs up 5%. These are supply constraints that would be bullish under normal demand conditions, but are instead colliding with a simultaneous demand shock. On the demand side, China's imports of unwrought copper fell 10.9% in March, yet the Yangshan copper premium climbed to $69 per ton on March 29, its highest since June 2025, a signal that spot buying appetite is quietly recovering ahead of the May Day holiday despite the headline weakness. Chinese smelters set a production record of 1.33 million tons in March, the highest in data going back to 1990, though seasonal maintenance is expected to pull output lower through May. On policy, the Trump administration revised Section 232 tariffs on copper derivative products on April 2, and the broader refined copper tariff decision remains unresolved. Goldman Sachs forecasts a 490,000-ton 2026 surplus while J.P. Morgan sees a 330,000-ton deficit; that wide disagreement between two major institutions is itself a signal of how genuinely uncertain the supply balance is. The two variables that could resolve this compression are an Iran ceasefire that reopens shipping lanes and a mid-2026 tariff announcement that ends the US stockpiling trade. What the Market Has Done The market was in a consolidation block between 6.15, which is the composite VAH, and 5.655, which is the December VAH, establishing a well defined balance area over multiple weeks. There was a spike high above the block at the end of January, but this move was quickly rejected back into range the following session, driven by profit taking and a lack of follow through buying as macro conditions at the time, including a firmer US dollar and cautious China demand signals, failed to support acceptance at higher prices. In the second half of March, the market broke out of the range below 5.655 and attempted to accept lower, signaling potential continuation to the downside. Sellers failed to gain control as buyers defended the 5.229 level, which aligns with the bid block mid, indicating responsive demand stepping in at lower prices. By the first week of April, buyers were able to bid prices back into the consolidation block, reclaiming prior value and negating the downside breakout. The market subsequently moved up aggressively through the consolidation block and tested 6.15, the composite VAH, showing strong initiative buying. Price action is now in a tight range, compressing just below 6.15, indicating a potential buildup for a directional move depending on acceptance or rejection at this key level. What to Expect in the Coming Weeks The key level to watch is 6.15 (Composite VAH). Bullish Scenario If the market is able to break and accept above 6.15, expect a move to 6.3555, which is the spike HVN. If there are no sellers present at that level, a continuation move toward the 6.62 area, which marks the spike high, becomes increasingly likely. The possible macro catalyst that could trigger this move is a ceasefire extension or diplomatic breakthrough in the Iran conflict leading to a reopening of the Strait of Hormuz. A resolution would immediately ease energy price pressures, reduce demand destruction fears, and likely spark a relief rally across industrial metals. A simultaneous announcement of a delay or softening in US refined copper tariffs would amplify the move further. Bearish Scenario If buyers fail to break higher at 6.15, expect long liquidation and a move down to 5.885, which is the consolidation block mid, where buyers are expected to defend. If this level fails to hold, the market could rotate through the rest of the consolidation block, targeting 5.655, which is the consolidation block low. The possible macro scenario that could drive this outcome is an escalation of the Iran conflict, specifically a breakdown in ceasefire talks and a resumption of full Strait of Hormuz disruption. J.P. Morgan noted that copper prices have historically troughed approximately 25% below their peak during major macroeconomic shocks, and Goldman Sachs flagged that Brent oil sustained at $110 per barrel or higher would strip more than one percentage point from copper demand growth. A combination of continued energy shock and a faster-than-expected tariff implementation that signals the end of US stockpiling could also produce this outcome. Neutral Scenario In the case of a false break above 6.15 followed by responsive sellers, combined with responsive buyers stepping in at 5.885, expect two way rotation between these levels. This would likely result in continued balance as the market works to repair and fill in the April low volume area. The current macro environment is actually well-suited to this outcome, as the ongoing ceasefire ambiguity in the Iran conflict keeps both upside catalysts (resolution) and downside risks (escalation) in play simultaneously, making it difficult for the market to commit to a trend. Conclusion HG copper is compressing against the Composite VAH at 6.15 with initiative buyers clearly in control of the narrative coming off the 5.229 bid block mid, yet the macro backdrop remains too unsettled to hand either side a clean edge. The sulfuric acid supply risk across the DRC and Chile is a genuine structural threat that most participants are still not fully pricing, while China's quiet Yangshan restocking beneath the surface contrasts with the bearish headline import figures. The Iran ceasefire status and the mid-2026 refined copper tariff decision are the two macro variables that will ultimately determine whether this compression resolves higher toward 6.3555 and 6.62, grinds lower through 5.885 and back toward 5.655, or simply churns between these poles repairing the April LVA. Price acceptance or rejection at 6.15 in the sessions ahead will be the clearest real-time read available. Are you fading this level or trading the breakout? Disclaimer: This is not financial advice.
