Japanese Government Bond Yields Surged with Increased Probability of Rate Hike, Frequent Macro Disturbances Led to Copper Prices Retreating After Rapid Rise [SMM Macro Weekly Review]

Published: May 15, 2026 16:02

Early this week, the market continued to trade around geopolitical tensions, inflation expectations, and the rise in global long-end yields. US April non-farm payrolls added 115,000 jobs with the unemployment rate holding at 4.3%, indicating continued employment resilience. Subsequently, US April CPI rose to 3.8% YoY and PPI to 6.0% YoY, with retail sales growing consecutively, further reinforcing market expectations of "reflation" and the US Fed maintaining a tight policy stance. Meanwhile, Japan's April corporate goods prices rose 4.9% YoY, and the 10-year JGB yield climbed to a nearly 29-year high, with Japan's long-end rate center shifting upward. Overall, the macro theme this week remained the resonance between US inflation and economic resilience, with rising JGB and US Treasury yields suppressing risk appetite, while recurring Middle East tensions and supply concerns provided support for copper prices, which rallied before pulling back.

Fundamentals side, supply disruptions remained a key support for copper prices' rise this week. On one hand, recurring Middle East tensions disrupted shipping through the Strait of Hormuz, with oil prices fluctuating at highs and continuously pushing up smelting and logistics costs. On the other hand, the Peruvian government approved on May 11 state-owned oil company Petroperu to seek a $2 billion state-backed loan to maintain operations, indirectly confirming that the local energy system remained under strain, and market concerns over ore supply disruptions had not subsided. China's spot cargo side was affected by the approaching delivery month, with suppliers showing increased willingness to ship to delivery warehouses, and overall spot circulation remained tight. However, high copper prices continued to suppress downstream purchase willingness, with the market still dominated by rigid restocking demand. Inventory rebounded slightly after destocking, and fundamentals exhibited a supply-demand dual-weakness structure.

Looking ahead to next week, the macro logic is unlikely to change significantly in the near term. If US inflation stays high and global long-end yields continue to rise, the US dollar and interest rate side will still cap copper prices to some extent. However, given that Middle East tensions and Strait of Hormuz disruptions have not truly been resolved, coupled with ongoing risks on the ore and energy fronts, downside support for copper prices also remains strong. A short-term pullback is expected but with limited magnitude. LME copper is expected to fluctuate within $13,400-13,850/mt, and SHFE copper within 104,000-107,000 yuan/mt. Spot cargo side, supported by delivery logic and tight circulation, premiums are expected to remain firm, but downstream willingness to chase higher prices is limited under elevated prices, and overall trading activity may remain cautious. Spot prices against the SHFE copper front-month contract are expected to range from a discount of 80 yuan/mt to a premium of 100 yuan/mt.
