Copper fell in Asian trade after reports the Trump administration delayed a decision on import tariffs for refined copper, ANZ research said. Traders had built large US inventories anticipating tariffs. ANZ said rising inflation concerns are making the White House hesitant about the tariff plan.

At a results briefing Guoguang Co. said El Nifio has driven localized extreme weather—heavy rains and floods in some regions and high temperatures and drought in others. Some of the company’s plant growth regulators offer stress resistance, root promotion and anti-lodging effects, which can boost regional demand (e.g. growth control/anti-lodging products in wet, windy areas; heat/drought-resilience products in dry areas). However, demand also depends on planting area, crop mix, climate, farmgate prices and farmer usage habits, so climate effects are regional. The company has not found El Nifio to have a material impact on overall operating performance to date.
