Earlier, Andrew Brenner, co-head of structured products and emerging markets at MF Global noted "the new money flows are going into corporate [bonds] and mortgages."
Several portfolio managers have said that yields on corporate bonds are factoring in much higher defaults than what they say will actually occur, even in a recession. More interest in the securities brings down the yields that companies need to offer to draw interest.
Indeed, the yield that companies have to pay for their debt above Treasurys has shrunk to the smallest since October. An index of corporate debt compiled by Merrill Lynch shows companies are paying 5.62 percentage points more than Treasurys, down from as high as 6.56 points in early December.
Mortgage bonds are gaining greater investor interest as well, as the Federal Reserve began buying mortgage-backed securities last week in an effort to stabilize the housing market. The U.S. central bank bought about $10 billion in mortgage bonds, the start of about $500 billion in purchases, it said. See related story.
According to Merrill, the gap between what mortgage-backed securities pay in the way of interest and the yield on Treasurys fell to 1.17 percentage points on Friday, near the lowest since September, when the global financial crisis deepened.
