Key Takeaways
- Copper prices topped $14,000 a ton on the London Metal Exchange (LME), reaching their highest level since mid-May as traders brace for a critical U.S. import tariff decision.
- U.S. copper imports surged to over 200,000 tons in July, the highest monthly volume since 2014, as market participants aggressively stockpile metal ahead of potential trade barriers.
- LME inventories hit a five-month low as metal is diverted to China to address a domestic shortage, pushing the market into a steep $99.50-a-ton backwardation.
- Iran is proposing a "voluntary fund" for European and Gulf nations to finance the upkeep of the Strait of Hormuz, a move aimed at formalizing control over the strategic waterway.
- Global markets are showing signs of "Trump fatigue," with world leaders and traders increasingly shrugging off the U.S. President's frequent threats of unilateral executive action and military strikes.
Copper Markets Tighten Amid Tariff Speculation
Copper futures advanced to $14,066.50 a ton on the LME, a 1.4% gain, while COMEX copper rose as much as 2.3% to approach its May record high. The rally is being fueled by a massive influx of refined copper into the United States, where more than 200,000 tons arrived at ports in July alone. Traders are front-loading shipments to avoid anticipated tariffs from the Trump administration, following a June 30 deadline for a formal recommendation on the matter.
The concentration of metal in the U.S. has sapped availability for the rest of the world, leaving LME inventories at a five-month low. This physical tightness has forced the market into a steep backwardation, where nearby contracts trade at a $99.50-a-ton premium over three-month futures—the widest spread since January. Mining equities reacted positively to the price action, with Freeport-McMoRan (FCX) rising 4.7% and Teck Resources (TECK) climbing 6.4%.
Iran Proposes New Fee Structure for Strait of Hormuz
Tehran is considering a proposal to charge European countries for the "upkeep" of the Strait of Hormuz, a strategic chokepoint that has been largely restricted since February 2026. The plan, reportedly facilitated by Oman, would establish a "voluntary fund" financed by Gulf countries and European members of the International Maritime Organisation. The fees would ostensibly cover navigation management, environmental protection, and search and rescue services.
The proposal is modeled after existing arrangements in the Strait of Malacca, but analysts warn it may be a thinly veiled attempt by Iran to exert permanent administrative control. While Oman and some European sources have tested the idea of voluntary fees to lower regional tensions, the U.S. and several Gulf states remain wary of any arrangement that could be viewed as paying "tolls" to Tehran.
Diminishing Impact of Presidential Threats
Despite the ongoing conflict and the threat of fresh tariffs, global markets have become increasingly desensitized to President Trump's rhetoric. Analysts note that the refrain "TACO" (Trump Always Chickens Out) has taken hold in international capitals as previous threats against China, Brazil, and Iran failed to produce the intended capitulations.
When the President announced new tariffs last month based on child labor accusations—a move intended to bypass Supreme Court limits—markets hardly moved, and foreign governments largely ignored the bluster. However, some analysts warn that this "shrugging off" of threats could lead to less predictability if the administration turns to more unilateral executive actions to regain leverage.
