Gokarn got some mild revenge soon after over the issue of curbing gold demand. He suggested several financial instruments as an alternative to physical investment in gold, but Rajendran countered with a novel idea — increase locker rents 10 times to discourage people from buying gold. The idea would work because women don’t feel safe wearing gold in public these days and store all of it in banks. “Locker charges are not regulated, so no one stops you from doing that,” came Gokarn’s quick response.
