Copper prices slumped after the Fed did not signal a clear slowdown in rate hikes, and the dollar index rallied. Copper later recovered some losses after the Las Bambas mine in Peru began cutting operations because of blockades.
Three-month LME copper was down 0.8% at $7,566 a tonne.
A stronger dollar and expectations of prolonged tight policy weigh on base metals, while supply disruptions from mine blockades provide some offsetting support. For feed buyers, the signal is mainly through dollar strength and broader commodity sentiment.
After 2,356 past bullish macro events, US Dollar (Broad) moved a median +0.2% over 5 sessions (60% higher; middle half -0.3% to +0.7%), and +0.4% over 20.
