WASHINGTON, DC – Much of the hype surrounding last month’s meeting in Moscow of G-20 finance ministers and central bankers was dedicated to so-called “currency wars,” which some developing-country officials have accused advanced countries of waging by pursuing unconventional monetary policies. But another crucial issue – that of long-term investment financing – was largely neglected, even though the endgame for unconventional monetary policy will require the revitalization or creation of new long-term assets and liabilities in the global economy.
