Copper futures were trading flat on Monday after US President Donald Trump's decision to impose fresh tariffs raised concerns of a global trade war and limited the scope for US interest rate cuts. Trump said he would announce on Monday 25% tariffs on all steel and aluminium imports into the US and reveal other reciprocal tariffs on Tuesday or Wednesday.
Copper futures for March delivery unchanged at $4.5890 a pound on the Comex metals division of New York Mercantile Exchange.
