Geopolitical Cooling Meets Sticky Inflation, Copper Prices Swing Wildly at Highs [SMM Macro Weekly Review]

This week, macro sentiment was shaped by two key narratives: accelerating US-Iran peace talks and higher-than-expected inflation. Peace talks notably heated up—Trump said a peace deal could be signed in Europe as soon as this weekend, and Iran allowed 10 tankers through the Strait of Hormuz as a goodwill gesture. Brent crude fell to a near two-month low of around $89/bbl as geopolitical risk premiums quickly faded. Mid-week, however, May CPI rose to 4.2% YoY, the first breach above 4% in three years (driven by energy, with core at 2.9%). The market’s expectation for the US Fed shifted from rate cuts to a possible hike within the year, and tightening fears weighed on industrial metals demand; copper prices briefly hit a three-week low. By the week’s end, optimism around US-Iran relations eased growth concerns, and copper prices rebounded, with COMEX recovering to around $6.35/lb. Overall, easing geopolitical tensions and sticky inflation offset each other. Ahead of the June 17 FOMC meeting (the first chaired by new Chair Warsh, who is expected to hold rates steady), the market leans toward a wait-and-see stance. Copper prices pulled back from highs on macro headwinds, with increased volatility.

Fundamentals side, China’s spot market notably strengthened. On inventory, SMM social inventory fell to recent lows, and suppliers showed a strong willingness to hold prices firm. Spot premiums quickly flipped from discounts; South China premiums surged around 230 yuan/mt in total this week, with the approaching delivery-related backwardation structure supporting SHFE copper premiums. Demand side, dip-buying activity picked up when copper prices fell and trading recovered, but as prices rebounded, downstream buying interest was suppressed and the market cooled—overall, demand remained need-based. The SHFE/LME price ratio recovered slightly, with buyers showing greater purchase willingness. The overall picture is one of low-inventory support, strengthening spot premiums, and a demand pattern that switches with price moves, lending support to copper’s downside.

Looking ahead to next week, macro focus will center on the June 17 FOMC meeting (attention on Warsh’s comments on the inflation overshoot and the dot plot), whether the US-Iran deal materializes and progress on Strait of Hormuz navigation resumption, while the June 30 US copper cathode tariff ruling adds further uncertainty. If peace talks deliver and geopolitical risk continues to recede, risk appetite could recover but crude oil and inflation expectations would likely pull back in tandem; if sticky inflation pushes the Fed hawkish, risk assets would face pressure. As for fundamentals, low inventories and strengthening spot premiums offer downside support, while high copper prices deter chasing. LME copper is expected to trade at $13,300–$13,800/mt, and SHFE copper is expected to trade at 102,800-105,500, moving sideways in a high range with a slightly softer center. Spot premiums are expected to persist; attention will focus on the sustainability of suppliers holding prices firm post-delivery and downstream restocking intensity.
