(Bloomberg) -- The market value of the world’s negative-yielding bonds plunged for the second week as investors continued dumping debt following Donald Trump’s upset victory. The amount of debt certain to lose money if held to maturity fell to $7.6 trillion, the lowest on a month-end basis since January, amid speculation that the U.S. president-elect will flood the market with new Treasuries and boost inflation. The Bloomberg Barclays Global Aggregate Index of government, corporate and securitized bond prices worldwide fell 4.7 percent in the past two weeks, the biggest such drop since at least January 1999, as far back as weekly data goes. --With assistance from Natalie Serrano To contact the reporter on this story: Phil Kuntz in New York at pkuntz1@bloomberg.net To contact the editors responsible for this story: Nikolaj Gammeltoft at ngammeltoft@bloomberg.netSophie Caronello
