JOHNATHAN PEARCE on the growth of sovereign wealth funds: “The truth is, emerging economies in Asia, coupled with the petro-dollar wealth of the MidEast, parts of Asia, Russia and even Africa, is giving these funds a degree of market muscle that has taken some investment observers by surprise, but it should not do so. We are living through a major period of change in the economic clout of non-western states. We might as well learn to profit from it.”
