Actually thats an interesting thing. M2 money supply is declining, and has been falling for a while. And thats something Fed has no control over. And that really worries them. Thats real weakness in the economy.
As for what the Fed supplies... http://wallstreetexaminer.com/ Great site with excellent daily analysys of the Fed and great charts, charting FCB and Fed actions.
Unfortunately if you're not a subscriber, I don't know how to get access to it.
If I find some free charts on the subject I'll post.
