Issuance of junk bonds in 2012 reached $274 billion in 2012, an increase of 55% over 2011, according to Dealogic. This is double the levels observed before the financial crisis of 2008. Yields on low rated junk bonds have declined to about 6% as prices move up. Also observed is an increase in covenant lite corporate loans. These types of loans relax lending standards- this increased from $8.5 billion in 2010 to $36.5 billion 2011, and $58 billion in 2012, according to Dealogic. This has drawn the attention of Fed Governors Jeremy Stein and Richard Fisher of the Dallas Fed, who have raised a warning about the rapid increase in credit and financial risks.
