Legendary bond investor Bill Gross has warned central bank policies that pushed trillions of dollars into bonds with negative interest rates will eventually backfire violently.

"Global yields lowest in 500 years of recorded history," Gross, 72, wrote this week on the Janus Capital Group Twitter site. "$US10 trillion of neg. rate bonds. This is a supernova that will explode one day."

Galaxy where a supernova probably resulted in a black hole: Are global bond markets facing a similar fate?

A supernova is a star at the end of its life that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.

Gross, who manages the $US1.4 billion ($1.9 billion) Janus Global Unconstrained Bond Fund, has argued for some time that the economy is at the end of a decades-long cycle of expanding credit that has culminated in negative interest rates, a situation he said is unsustainable.
