Wheat markets could be getting a demand bump from an unlikely source in 2022-23, says an analyst. Tight global rice supplies could result in changing trade patterns in the Indian Subcontinent. “There could be some wheat that has to be used as a substitute for rice,” said MarketsFarm analyst Bruce Burnett. On Sept. 9, India imposed a ban on exports of broken rice and a 20 percent export tariff on paddy, brown and white rice that is neither basmati nor parboiled rice.
