(Reuters) - China's commodity exchanges have hiked transaction fees and margin requirements for a range of futures this year in their latest effort to curb speculative trading that Beijing says has spurred recent price surges in markets from sugar to ferro-silicon.
The Zhengzhou Commodity Exchange has hiked transaction fees and issued risk warning statement for ferro-silicon against recent surge in the market.
In the past two years, the Dalian Commodity Exchange, Shanghai Futures Exchange and Zhengzhou have all used fee hikes and position limit curbs as ways to snuff out speculative rallies that the authorities say are not justified by fundamentals.
