Yes, an all time high of ~47% which is ~1% over the last all time high. Not as big of a doomsday headline though. It also doesn't take into account that corporate profits are also at highs.
I'm not saying that continuing to increase corporate debt is necessarily good. But, the fear mongering of 10T alone without looking at the whole picture is disingenuous. A much better article with more of the picture is here.
Rates have been very low for a very long time, you would expect to all time high debt with current interest rates. It would be more concerning if people were not taking advantage of the essentially free money.
I'd be concerned if the idiots taking decisions and crashing the financial system when interest rates were at 5% were not severly punished and let loose when interest rates were at 0%, almost like an arsonist being put in charge of a gas station.
Oh wait, they weren't....
Has that ratio changed in the recent past?
nevermind -- I looked it up and it's at all time high.
