Copper prices are experiencing volatility as market participants assess two major opposing forces: positive developments in US-Iran peace talks and a more hawkish stance from the Federal Reserve.

On one hand, there's optimism stemming from reports of "major progress" in peace talks between Iran and the US. These talks, which are set to continue this week in Switzerland, are expected to lead to the restoration of traffic through the Strait of Hormuz. This prospect is easing inflation fears and boosting expectations for global manufacturing activity, a key driver for industrial metals demand. An interim agreement in mid-June saw copper prices rise by as much as 4.4% on the London Metal Exchange, with further gains linked to easing Middle East tensions and renewed claims of momentum toward ending the conflict.

Conversely, a stronger dollar and the Federal Reserve's hawkish stance are exerting downward pressure on copper and other industrial metals. Growing convictions that interest rates will remain high for longer are dampening investor appetite for risk assets. A rising dollar also makes commodities priced in the currency more expensive for international buyers, further impacting demand. This led to copper extending losses by as much as 2.1% on the London Metal Exchange, though it later edged higher after touching a seven-week low, buoyed by a weakening dollar and an artificial intelligence stock rally.

The overall sentiment remains mixed. While the easing of geopolitical tensions and the potential for a resumption of oil shipments from Iran offer support to copper prices by reducing inflation concerns and potentially stimulating global growth, the Federal Reserve's commitment to higher interest rates continues to be a significant headwind.

Analysts are keenly watching the continued peace talks and upcoming statements from the Federal Reserve to gauge the future direction of copper prices, as these two factors are currently the primary drivers of market sentiment for the metal.
