Why did copper prices decline on Wednesday despite expectations of U.S. import tariffs?

Copper prices declined because volatility from the Middle East conflict and broader macroeconomic concerns—including rising inflation fears, stronger U.S. dollar pressure following robust jobs data, and heightened expectations of a Federal Reserve rate hike—outweighed ongoing price support from anticipated U.S. copper tariffs, which are proposed as a 15% levy starting in 2027 and rising to 30% in 2028.

What key supply and demand signals were reported in the news regarding copper markets?

On the supply side, LME-registered copper stocks have declined each day since May 28; on the demand side, China’s producer price index rose for a third straight month in May to its highest level since 2022—driven by higher commodity prices and improved demand in certain industries—while simultaneously, the Middle East war has strained manufacturing (a major copper-consuming sector) and pushed up energy prices.
