“From the times when kings invested in building pyramids, raising armies and bankrolling explorers, sovereign wealth attracted political controversy,” says Alexander Mirtchev, president of Krull, an advisory and project management firm based in Washington, DC. “But sovereigns have changed with the times and today represent internationally legitimate public authorities,” according to Mirtchev, who is an independent director of Kazakhstan’s SWF, Samruk-Kazyna. “Cooperation among SWFs and their managers on different projects represents a sign of their maturity as investors who have become more aware of the market opportunities,” Mirtchev says. “On certain occasions, it could help funds to become market leaders in specific sectors,” he says.
