On the macro front, US and Iranian officials held a productive meeting. Trump said they would meet again soon and believed an agreement could be reached after the midterm elections; Iran proposed conditions for reopening the strait, including lifting the blockade and unfreezing assets. Saudi Arabia restarted the east-west pipeline and resumed exports from Yanbu, and Asian refiners received assurances from Saudi Arabia that they could lift cargoes soon. Crude oil prices continued to drift lower, easing inflationary pressure. Coupled with tight domestic spot supply, this provided support for copper prices. Fundamentals: On the supply side, available cargoes remained tight, suppliers held back from selling, import arrivals were limited, and overall supply is tight. On the demand side, pre-holiday stocking demand remained, but downstream buyers were less willing to chase higher prices, with purchases mainly driven by rigid demand. Overall, copper prices were expected to maintain a fluctuating trend and hold up well today.
