Financial conditions- as measured by the quantity of money available and the availability of credit- tightened in the fourth quarter of 2009. Issuance of asset backed securities went down from $51 billon in the third quarter to $29 billion in the fourth quarter, and commercial paper outstanding declined to $1.1 trillion in January 2010 from $1.3 trillion in September 2009. A ""financial conditions index" produced by Columbia, NYU, Princeton and Deutsche bank, Goldman Sachs, shows the conditions tightening, revealing a financial sector that remains weak and impaired even with very low rates by the Fed.
