Talk:Bond equivalent yield

From what I understand the rate of return on bond debt moves in opposite direction to its yield. When treasury debt is purchased there is a discount rate, which expresses the difference between the amount of debt sold and the return on investment over a period of time. I have read articles in the Economist magazine discussing the debt of various countries in the European Union, and how the Euro currency is effected by varying levels of debt spread amongst the member nations. I am interested, but do not completely understand the phenomenae of how there are high "yields" for increasing indebtedness, which I suppose translates into higher interest rates, and at the same time the rate of return for investors supposedly decreases?
