From Marketwatch:
The Federal Reserve on Wednesday surprised financial markets and committed to buy $300 billion in longer-term Treasurys to help the struggling American economy recover.The Fed also tweaked its other credit-easing programs by committing to buy more mortgage-backed securities and agency debt and include more asset-backed securities under a new credit facility starting this week.Most analysts had thought that the Federal Open Market Committee - the policy making arm of the central bank -- would keep the weapon of buying Treasurys in reserve in case of a crisis.The decision to buy Treasurys shows that the crisis is here.
