Escalating US-Iran tensions, rising oil prices, inflation fears, and a stronger dollar dragged base metal prices lower amid weakening demand expectations.
Base metals have experienced a significant decline following renewed hostilities between the United States and Iran in July 2026. This geopolitical flare-up has intensified concerns about global economic growth, casting a shadow over the demand outlook for industrial commodities. The conflict also fueled expectations for higher inflation and interest rates, further impacting market sentiment.
The latest escalation began after Iran reportedly struck a vessel on an unapproved route. Subsequently, Iran announced the closure of the Strait of Hormuz. The US Central Command responded by conducting strikes on Tehran. Iran then retaliated by targeting American-linked installations in the United Arab Emirates, Kuwait, and Bahrain. On July 8, 2026, President Donald Trump declared that a fragile ceasefire with Iran was over, marking a definitive end to a period of relative calm.
The renewed tensions have revived worries about weaker global economic growth. This directly translates to reduced demand for metals. The International Monetary Fund (IMF) emphasized the persistent risks to global growth and inflation stemming from the Middle East conflict.
Furthermore, the conflict has driven crude oil prices higher, surging approximately 5% to a two-week high. This rise in oil prices is expected to ignite inflation concerns. Consequently, analysts anticipate central banks will likely maintain higher interest rates for an extended period. Higher interest rates generally create headwinds for non-yielding assets, including precious and industrial metals. A strengthening US dollar, often a safe-haven asset during uncertainty, has also added pressure to metal prices.
The decline affected a wide range of base metals. Copper, aluminum, nickel, zinc, tin, and lead all saw decreases. Aluminum, for instance, experienced a substantial 16% drop in June, marking its most significant monthly decline since the 2008 global financial crisis. This initial fall was partly due to earlier peace talks, which reduced a perceived "war risk premium." However, renewed tensions caused further dips.
Even precious metals, typically considered safe havens, faced downward pressure. Gold and silver declined due to the stronger US dollar, firm crude oil prices, and expectations of higher interest rates. Gold fell below $4,000 an ounce and further to $3,943 in late June. The market is currently balancing two competing forces: a weaker labor market, which might suggest lower interest rates, against the escalating Middle East conflict, which pushes oil prices, inflation, and bond yields higher, negatively impacting metals.
Impact on Base Metals Tracked by ChemAnalyst
The renewed US-Iran conflict is expected to exert bearish pressure on base metals tracked by ChemAnalyst, including Copper, Aluminum, Nickel, Zinc, Lead, and Tin. Escalating geopolitical tensions have heightened concerns over slowing global economic growth, weakening manufacturing activity, and softer industrial demand, which are likely to outweigh supply-side risks in the near term. Rising crude oil prices and expectations of prolonged high interest rates have strengthened the US dollar, making dollar-denominated metals more expensive for overseas buyers and reducing purchasing activity. Consequently, Copper and Aluminum may witness the sharpest price declines due to their strong exposure to the construction and manufacturing sectors, while Nickel and Zinc could face weaker demand from the stainless steel and galvanizing industries. Although potential shipping disruptions through the Strait of Hormuz may temporarily increase freight and logistics costs, the prevailing weak demand outlook is expected to keep base metal prices volatile with a downward bias until geopolitical tensions and macroeconomic uncertainty subside.
