Trading on the London Metal Exchange hit record levels last month, according to figures released this week, four months after London’s oldest commodity exchange was bought by the Asian bourse Hong Kong Exchanges & Clearing.

Trading on the exchange reached 14.517 million lots during April, a 4% increase on March. It marked a record number of lots traded on the LME in a single month, exceeding the previous high set in November 2012, when 14.513 million lots were traded.
