Stuff is already breaking in the economy(layoffs starting here, inventories are back up and some are reporting surplus, china playing possum with their economy) ....Jay won't be able to keep the bar up high past early fall especially when the corporates can't refinance their debt into lower rates which equal piss poor earnings and....wait for it....layoffs.
The FED has already broken the stock market and doesn't care....but when corps can get low enough bonds Jay will rollout the printer again....the big question is when? He can't afford to shoot the Housing, Stock, and Bond market all at once...but each will taking a beating in the mean time. Oh and remember Powell is a Republican sooooo he might keep the pressure on longer this time.
