The spread between Corporate Bonds and Government Bonds are blowing out once again. As the risk for holding a corporate bond is perceived higher, the yields will often increase to entice buyers to holding a bond with the higher risk.
As the bond market is a snapshot of the wider credit market, large market moves downward seem probable in the next few weeks.
It's a good point gfresh. Credit spreads are widening, the latest fed senior loan officer survey shows that financial instituions are still overwhelmingly tightening credit standards. Banks need to refinance huge amounts of debt and are borrowing record amounts from the Fed.
The credit markets are telling a different story from the equity markets. To some extent extent, equities have been keying off oil but a fresh round of credit concerns will trump the benefits of lower oil IMO.
