That low interest rates would lead to a bubble...I mean how many times did bubble bernanke say that there was no subprime mortgage problems and the housing markets ludicrous prices were going to be sustained without any such thing as a hard landing.... Why would anyone at the federal reserve admit to an economy being in a bubble ...they always say pretty nice things...they wouldn't want to scare the markets especially now at historical highs... http://www.cnbc.com/id/102190887 Powell is saying low interest rates not creating stock maket bubble... Tell that to greenspan bernanke and yellen...
