China’s Dalian Commodity Exchange said it would strengthen its supervision and investigate trading violations after a surge in volumes drove the price of iron ore up over 50 per cent this year.

中国的大连商品交易所(Dalian Commodity Exchange)表示将加强对异常交易行为的监管，加大稽查工作力度，打击违规违法行为。最近成交量激增使铁矿石价格今年以来上涨50%。

The exchange said investors should maintain a “clear understanding” and increase the knowledge of the rules to maintain and orderly market, according to a statement on its website. This year a total of 212 traders had been given warnings and 13 accounts closed, it said, writes Henry Sanderson in London.

Dalian and other exchanges in China have raised transaction fees in an attempt to cool the speculative fervor, which saw trading in steel futures surpass the country’s entire stock markets last week.
