Wall Street Journal writes "Money Funds Fret Over Merrill Downgrade". In an apparent attempt to write an article a day on money funds, the Journal speculates that a downgrade of Merrill Lynch may impact tax-exempt money market funds. "The downgrade is raising questions about whether these mutual funds -- primarily tax-exempt, money-market funds -- can continue to hold some short-term municipal securities tied to Merrill. The securities in question total an estimated $4 billion to $6 billion," says the WSJ.
