Defaults and pulled sales are starting to gum up China’s bond refinancing machine. Chinese companies issued 382.7 billion yuan ($58.5 billion) of notes onshore this month, down 11% from the same period in April and 57% March, data compiled by Bloomberg show. With just eight trading days to go, fundraising may fall short of the record 547.3 billion yuan of debt due. That would mark a shift after sales were 83% more than maturities in April and almost three times higher in March. The faltering $3 trillion corporate bond market will test Premier Li Keqiang’s determination to weed out zombie companies. At least 10 issuers have reneged on onshore debt obligations this year.
