Safe havens are now risky
Developed countries' sovereign debt is losing some of its appeal, writesCarrie Lam

Sovereign debt forms, or sovereign bonds, are one of the oldest types of investments and are considered one of the safest.
This type of investment is divided into two categories. Developed countries that carry very high credit ratings are viewed as safe options. However, they offer comparatively lower yields.
Emerging countries, meanwhile, usually come with lower credit ratings but offer higher returns.
This was the traditional definition of sovereign bonds that has been a textbook guideline for many investors over the past decades.
However, since the European debt crisis swept in, developed countries have been viewed as risky.
"The European crisis has presented some compelling investment opportunities in sovereign bonds, but they are not without risk and further volatility," says Owen Murfin, managing director and portfolio manager in BlackRock's global bond portfolio team.
