The market is worried that the US will delay deciding whether to impose import tariffs, and copper prices are expected to record their first weekly decline since June. After the London market fell 3.6% on Thursday, futures prices rebounded slightly, retreating from record highs set earlier in the session. According to media reports, US officials are weighing up a concern: if tariffs are implemented, domestic copper prices may increase manufacturing costs, and the news will trigger a reversal of the situation. Copper prices fell 0.6% cumulatively this week. Copper traders have transferred hundreds of thousands of tons of copper to the US, hoping that the Trump administration will tax refined metal imports to benefit from rising domestic prices due to tariffs. Expectations of increased demand brought about by data centers and renewable energy, combined with supply blockages in major mines, have also boosted investors' purchases. Analysts at BMI, a subsidiary of Fitch Solutions, said in a report: “This round of upward market growth seems to have exceeded a reasonable range that fundamentals can support. “Tariff uncertainty remains high.” US consumer price data will be released later on Friday, and copper and other assets will be tested. If the data shows a recovery in inflation, the market will raise expectations for the Fed's interest rate hike, and interest rate hikes will usually be bad for interest-free assets such as copper.
