Copper slid more than 1% on Tuesday, erasing gains that had built up earlier in the week. The decline followed comments from Federal Reserve Chair Kevin Warsh at his first press conference. His remarks stoked speculation that the central bank might lift rate hikes sooner than expected.

Copper remains a barometer for global infrastructure spending. A dip of this magnitude can pressure manufacturers and raise borrowing costs for projects that rely on the metal. Investors watch the currency pair and the U.S. dollar closely, as tighter policy tends to lift the dollar and depress commodity prices.

The market reaction underscores how Fed rhetoric can ripple through commodity chains. A 1% fall translates into tens of millions of dollars in market value for copper traders and signals that inflation concerns are still alive. Corporate planners may pause large purchases until policy direction clarifies.

Short‑term volatility is likely to persist as traders digest Warsh’s hints. Copper’s price will settle around its previous support levels unless the Fed signals a decisive shift. Market participants should monitor subsequent policy meetings for confirmation of the rate trajectory.
