Copper prices peaked at US$6.89 per pound this week. The surge followed inventory shifts ahead of new tariffs. Gold prices declined as rate hike odds rose.

Copper prices reached a record high of US$6.89 per pound on the COMEX. This peak occurred during intraday trading on Wednesday, September 9. The London Metal Exchange also recorded a high of US$14,858 per metric ton. The price spike coincided with tightening physical stockpiles outside the United States. Traders accumulated refined copper inventories in anticipation of a new 15 percent tariff. This tariff is scheduled to take effect on January 1, 2027.

US domestic stockpiles rose to record levels. Meanwhile, inventories at LME and Shanghai warehouses fell. This divergence reduced the availability of physical copper overseas. By the end of the week, prices began to retreat. Speculation grew that the administration might delay the phased tariff implementation. Officials weighed higher manufacturing costs against the need to stimulate domestic production. The COMEX copper price closed the week at US$6.55, a 1.8 percent decrease.

Gold Prices Decline on Rate Hike Speculation

Gold prices trended downward throughout the week. The metal started trading at US$4,428 per ounce on Monday. By Friday morning, prices had pulled back near the US$4,300 mark. A brief spike above US$4,400 occurred after the release of August CPI data. Core inflation rose 0.3 percent monthly, exceeding the expected 0.2 percent. This hotter-than-expected data increased the odds of a Federal Reserve rate hike. The probability of a hike rose from under 50 percent to over 85 percent.

The Federal Open Market Committee meets next week to decide on the benchmark rate. President Donald Trump has called for rate cuts, creating potential conflict with the Fed. Fed Chair Kevin Warsh appeared hawkish at the Jackson Hole Symposium. He showed openness to future rate increases. Gold closed the week at US$4,350.04 per ounce, a 2.75 percent loss. Silver prices also fell, dropping 3.92 percent to US$64.39.

In contrast, the CSE Composite Index gained 3.75 percent to finish at 174.83. The S&P Goldman Sachs Commodities Index rose 2.03 percent to end the week at 752.08.
