The US economy is at risk of tipping into recession in the second half of this year, putting pressure on corporate debt markets, says Chris Alwine, global head of credit at Vanguard. “What would precipitate that shallow recession is that corporations are just not hiring, with a modest increase in layoffs,” said Alwine. Vanguard, one of the biggest money managers in the world, with $8.6 trillion in assets, is cautious on junk-rated debt, Alwine tells Bloomberg News’ Lisa Lee and James Crombie and Bloomberg Intelligence’s Stephen Flynn in the latest Credit Edge podcast. He meanwhile sees opportunity in the bonds of large financial institutions. Also in this episode, BI’s Flynn analyzes the debt troubles at Dish Network Corp. and what it means for the rest of the sector.  See omnystudio.com/listener for privacy information.
