FYI: It would be nice — and so, so easy — to ignore what bond markets are doing in Germany, Japan and Zambia. But you shouldn't.
If you own a bond mutual fund or have a 401(k) account, there's a good chance that you have foreign-bond investments, even if you don't know it. That's because many bond funds have been buying foreign bonds, including some that could serve as the only bond fund in your portfolio. Also, most target-date mutual funds, which have become the default way for many investors to save for retirement, keep small portions of their portfolios in foreign bonds.
