Lending Euros to Warren Buffett Can Hurt Your Financial Health

Investors who bought Berkshire Hathaway Inc.’s euro-denominated bonds in March are learning that the biggest beneficiary of the Sage of Omaha’s investing acumen is Warren Buffett.

Berkshire’s three deals maturing between eight and 20 years and totaling 3 billion euros ($3.3 billion) are all among the 40 worst-performing bonds issued in the single currency this year, data compiled by Bloomberg show. That gives the Omaha, Nebraska-based company Buffett chairs the largest number and greatest amount of underperformers in the ranking.
