Nickel rose for a third straight session, approaching a seven-year high on booming demand for the metal used in stainless steel and electric-vehicle batteries. Copper advanced the most in more than two months. Nickel gained as much as 2.1% to $19 780 a ton. It reached $20 110 in February, the highest since 2014. Declines in inventories and the dollar also lifted prices Monday. Most main metals traded in London rose, while spot gold was little changed as traders awaited a Federal Reserve meeting this week.
