U.S. mining stocks moved lower on Monday as precious metals prices came under pressure in the wake of renewed tensions between the U.S. and Iran. The rout in gold and silver occurred alongside a jump in crude oil, a firmer dollar and fresh uncertainty about a ceasefire, prompting investor caution toward miners.
Among names affected, Southern Copper, Newmont Goldcorp, Agnico Eagle Mines and Wheaton Precious Metals each retreated, with losses ranging roughly between 1.9% and 2.7%.
Gold briefly declined to a one-week low before a modest rebound, pressured as Iran threatened retaliation over a U.S. seizure of an Iranian cargo vessel. That incident lifted both the dollar and oil prices, undercutting safe-haven demand for non-yielding assets such as gold.
The seizure also cast doubt on the ceasefire between the two countries. Market reaction intensified after the U.S. fired on and captured an Iranian vessel that was reportedly attempting to skirt a blockade, an action President Donald Trump said had occurred on Sunday evening. Both sides subsequently accused the other of breaching the ceasefire.
Mr. Trump said U.S. envoys were en route to Pakistan for further ceasefire discussions. Iranian media, however, reported that Tehran had not committed to any future talks.
Crude oil surged, rising by about 5% on fears that the ceasefire could break down and that flows through the Strait of Hormuz might remain largely halted. At points, oil prices jumped as much as 7% on Monday, keeping markets on edge over the inflationary consequences of the Iran conflict.
Market participants cited concerns that energy-driven inflation, amplified by constrained supply through strategic shipping lanes, has been a persistent drag on metal prices since the conflict began in late February. Those inflation pressures raise the prospect that global central banks could respond with higher interest rates - an outlook that is typically unfavorable for non-yielding assets like gold.
Context for investors: The episode highlights how geopolitical disruptions to oil flows and a stronger dollar can quickly erode near-term demand for precious metals, pressuring mining equities even when underlying supply fundamentals are unchanged.
