Do a search, you will find all kinds of articles for and against this when it first came out, I just picked some of the first ones to come up.
You also have to take into consideration that they, the FED, was signaling before they raised rates that they where going to do so which they did June 2004. As far as I can tell or remember there was no retraction to this ‘suggestion’ to lenders and lendees.
Of course now Greenspan is trying to distance himself from this, well he has been doing this since late July of this year I believe or some time not long after that which is when the subprime was just starting to show its head to the public.
The above is the proof for your claim, "He also encouraged folks to go for the adjustable rate mortgages (ARMs) a month before they where going to do their interest rate rise for the next 2 years. He knew what they where going to do and why they where going it, yet encourage people to go into ARMs"?
Really?
