(IPS) – There are increasing warnings of an imminent new financial crisis, not only from the billionaire investor George Soros, but also from eminent economists associated with the Bank of International Settlements, the bank of central banks. The warnings come at a moment when there are signs of international capital flowing out of some emerging economies, including Turkey, Argentina and Indonesia. Some economists have been warning that the boom-bust cycle in capital flows to developing countries will cause disruption, when there is a turn from boom to bust. All it needs is a trigger, which may then snowball as investors in herd-like manner head for the exit door. Their behaviour is akin to a self- fulfilling prophecy: if enough speculative investors think this is the time to move back to the global financial capitals, then the exodus will happen, as it did in previous “bust” phases of the cycle.
