The trading fee increase had "no impact on LME trading volumes whatsoever," he said at a briefing following results of parent company Hong Kong Exchanges and Clearing Ltd (HKEx) on Wednesday.

Average daily LME traded volumes slipped by 3 percent in the first half of 2015 compared with the same period a year earlier, results showed.

The LME raised trading fees from Jan. 1, 2015, as part of efforts to commercialise the exchange and wring profits after it was taken over by HKEx in 2012.

Jones also said there were no firm plans for launching any iron ore products on the LME as of now.
