Shadow markets defined by Weiner:
[t]he shadow market is a collection of unaffiliated, extremely wealthy nations and investors that effectively run the international economy through their prodigious holdings of stocks, bonds, real estate, currencies, and other financial instruments, which they keep in largely unregulated investment vehicles such as hedge funds, private equity funds, and government-run sovereign wealth funds, as well as in vast government-owned holding companies...Given the enormous amount of money (approaching $20 trillion) in the shadow market, Weiner argues, the players in that market are beginning to exert significant influence in global politics.
