- the small change in policy.
For those of you into original sources, here is the Fed's statement
The economy is certainly growing, but not fast enough to make up much of the ground lost in the recession. We are still at least six percentage points below our potential, so the risk of going overboard on monetary stimulus is slight. The good news: the Fed is starting to understand this.
The second good news is that the Fed will stop allowing their credit to the public to contract. Background: the Fed bought a ton of mortgage-backed securities to help that market, and the portfolio is slowly running off. The change: the Fed will take the income and payoffs from that portfolio and use it to buy new Treasury securities, so their total impact on the economy will be unchanged. You can see how the run-off was contracting their total credit:
It's a move in the right direction, but nearly enough to get this malaise over.
