Macro
US equities opened mixed, with the broader market easing slightly from record highs as firmer oil and yields capped risk appetite, while AI-linked names continued to support tech.US-Iran tensions are still weighing on sentiment. Fresh strikes overnight were a reminder that the ceasefire is fragile and that the Strait of Hormuz remains a key geopolitical lever, leaving energy risk embedded even as talks continue. Oil strengthened again in response, with Brent near $98/bbl and WTI around $96/bbl. We expect energy to remain a key macro risk until the market gets something firmer than negotiation headlines.
At the same time, the tariff threat is reemerging, with the US proposing new 10% tariffs on 60 trading partners, including China, Mexico, and the European Union. As a result, the dollar index increased towards 99.5, and the US 10-year yield moved back towards 4.5%, supported by firmer oil and another solid labour signal after ADP showed private payrolls rising by 122,000 in May, above expectations. Markets still have little reason to price a meaningful fall in rates ahead of Friday’s payrolls report.
Base Metals
Base metals weakened today, primarily as markets unwound a portion of the recent technically driven gains.
Copper led the decline, with a firmer dollar prompting profit-taking across COMEX and dragging LME copper back below the $14,000/t mark to $13,860/t. Since the start of April, the market has increasingly priced in copper tariff risk, pushing the COMEX–LME arbitrage above $800/t, the widest level since July 2025, as participants position ahead of the upcoming Section 232 deadline at month-end. COMEX inventories continued to build, reinforcing the view that a significant portion of recent copper demand — and the corresponding strength in both COMEX and LME prices — has been driven by incentives to ship material into the US ahead of potential policy changes.
For us, this suggests copper price discovery is likely to remain heavily COMEX-led over the coming weeks, with positioning, inventory flows and tariff expectations exerting a greater influence than underlying physical demand trends. As a result, we view today's weakness as a healthy long liquidation phase rather than a broader change in trend. In fact, unless the arbitrage begins to narrow materially or inventory accumulation slows, pullbacks are likely to attract renewed buying interest from participants seeking to capture the remaining incentive to move metal into the US.
The rest of the base metals complex followed copper lower, with aluminium surrendering part of its recent gains to trade back toward $3,700/t, while zinc and lead eased from recent highs to $3,615/t and $2,030/t, respectively.
Precious Metals
As oil strengthened back to $98/bbl, precious metals followed base metals lower, with gold and silver falling to $4,450/oz and $73.50/oz, respectively, keeping the negative correlation attribute intact.
