When added to a well-rounded portfolio, international bonds present an opportunity to achieve lower risk-adjusted earnings than what the global equities markets typically provide. Exposure to global debt securities is attractive to investors wanting to diversify fixed income positions held in the domestic market with bonds issued by foreign entities. 

Within international bond mutual funds, managers select certain global debt positions with varied maturity dates, country exposure and overall default risk exposure to reduce the potential for loss within a portfolio while attempting to earn a modest return. Investors who want to participate in the international bond market through mutual funds should understand the risks by reviewing the current prospectus for the below funds, which have been the favorites among investors in 2018.
