Text book or no text book, IMF is the MOST RISKY institution and it is NOT suitable for investment purpose. Would you invest or make loans to a bank which keeps making loans to companies which are near bankruptcy?
MOST RISKY???
You need to rethink that. If you do a little research, you'll note that no country has lost money lending to the IMF in its 67-year history. That's hardly the credit risk profile of a "MOST RISKY institution".
