Interest Rate Spread
This is the danger that prevailing interest rates will rise significantly higher than the rate paid on bonds you are holding. This drives down the price of your bonds, so if you sell you'll lose money. This is a serious risk for anyone investing in long-term bonds, including Treasury, because the longer the maturity, the higher the interest rate risk.
