Silver and copper surge as China export bans disrupt supply

Silver and copper have staged a dramatic breakout this week, with silver jumping to 2-month highs and copper pushing to $13,619 per tonne on the LME, only 6% below January's all-time peak. The catalyst is China's unexpected ban on sulphuric acid exports, which is a critical input for acid leaching and refining processes in both precious and base metals. Mining traders on social media report that primary silver and copper miners cannot acquire refining inputs at scale, forcing supply chain disruptions that may persist for months.

Ole Hansen, a commodity strategist, has pegged $91.50 as a critical technical level for silver; the metal has broken cleanly above prior resistance on heavy physical demand and ETFExchange-Traded Fund - a basket of securities trading like a single stock. inflows. SLV, SIL, and other silver-linked ETFs are trading 26% above spot prices in some cases, signaling extreme retail demand and potential supply scarcity in physical markets. Copper beneficiaries include Teck Resources, Freeport-McMoRan, and Codelco, all of which face supply tightness as a structural tailwind. Chinese mining companies are actively scouting for gold and copper acquisitions in Africa and Central Asia to offset domestic supply constraints, suggesting Beijing is treating metal security as a strategic priority.

The breakout is being validated by both technical momentumThe empirical fact that winners keep winning over the medium term. and fundamental tightness. Copper has now entered a tighter market cycle than existed just three months ago; if geopolitical tensions persist and the Hormuz closure blocks fuel and refining materials, the rally could extend further. Macro traders view the precious metals move as a hedge against inflationThe rate at which prices rise across an economy. and currency debasement, especially given China's import dependency and the likelihood of prolonged sanctions on Iran. Gold is also testing $5,200 support levels, with some traders expecting a run to $5,500 if equity markets correct.

Downsides include: if China lifts the sulphuric acid ban as a negotiation tactic with the US, supply could normalize quickly and prices could roll over. Additionally, if the Hormuz strait reopens within weeks, energy prices collapse, and inflationThe rate at which prices rise across an economy. expectations reset, precious metals could face profit-taking. Copper's move is also dependent on continued AI data-center buildout (which requires substantial copper for power distribution and cooling), so any slowdown in capex could undermine the rally.
