Investors are running from junk bonds, with spreads widening to the highest levels since 2016, and junk bond funds losing suffering withdrawals of $11 billion over just the last six weeks alone. At Bloomberg, Kelsey Butler reports on the rout:

Pummeled by expectations of slower growth,ย outflows and dropping oil prices, junk bonds are poised forย their worst returns in more than seven years.

High-yield bonds are returning -2.64 percent in December,ย on track for the worst month since September 2011. The assetย class has lost 2.59 percent so far this year, set for theย biggest loss since returns fell 4.47 percent in 2015, accordingย to the Bloomberg Barclays High Yield Total Return Index.

โ€œExpectations around global growth are slowing, soย fundamentally that impacts credit, most notably in lower ratedย credits.โ€ said Joel Levington, director of credit research atย Bloomberg Intelligence. โ€œSecondly, you have large outflows ofย cash from ETFs, so technically, the sector has faced pressure asย well. Lastly, the B tier is composed with a large amount ofย energy credits, so the drop in oil prices has an immediateย impact there as well.โ€

Funds that invest in high-yield debt have seen massiveย outflows as investors have fled risk assets, yanking $11 billionย from the funds over the past six weeks, according to Lipper.

As returns have remained negative, high-yield spreads haveย risen this month to the widest level since the summer of 2016,ย and yields this week hit the highest level in 32 months.ย Most big banks see junk bonds having a better year in 2019.ย Return expectations for the coming year range from 0.5 percentย on the bearish end to 6 percent to 7 percent on the bullishย side.
