Collapse of the Auction Rate Bond Market

While this is still a developing story, check out the extent to which the market has collapsed . . . .

From 1984 through 2006, only 13 auctions failed, typically because of changes in the credit of the borrower, according to Moody's Investors Service. There were 31 failures in the second half of 2007, and 32 during a two-week period beginning in January.

The average rate for seven-day municipal auction bonds rose to a record 6.59 percent on Feb. 13 from 4.03 percent the previous week, according to indexes compiled by the Securities Industry and Financial Markets Association.
