This article is for subscribers only.
India, the world’s largest supplier of guar gum, lifted a ban on futures trading in the commodity used by Halliburton Co. to extract shale gas after a rally in prices spurred farmers to produce a record crop.
The National Commodity & Derivatives Exchange Ltd., or NCDEX, and the Multi Commodity Exchange of India Ltd. today began trading three contracts each in guar seed and guar gum, according to separate notices on the bourses’ websites. The Forward Markets Commission, the commodity market regulator, suspended futures trading in March 2012 to curb excessive speculation after prices surged nine-fold to a record.
