    AMU: Edward Meir’s week in review and thoughts for the week of Oct. 12, 2026

    Base metals had a mixed week. Tin lost almost 4% on the week, finishing at $53,000/ton. Prices dropped to a low of $51,259/ton at one point. Aluminum was another loser, off by about 1.6% on the week. Investors are expecting more aluminum supply going forward, especially out of China and Indonesia. Copper prices tacked on 1.1%. They have now recovered more than half of the $700/ton loss sustained (over the course of a week) following reports/rumors in mid-September that US tariffs on refined copper imports might not proceed after all.
