Guar gum is India’s largest commodity export to the US.
“From the global supply perspective, India is currently a dominant global producer of guar, accounting for about 80 per cent of world production. In India, the largest production centres are Rajasthan and Gujarat, which is where the big export surge is presumably originating. This concentration pattern provides a possible explanation for the price surge in 2012-13. Anticipation of a drought, which could have significantly reduced production in India (as happened in 2009-10), may have led to advance buying, pushing prices up.”
