Here is the list of yesterday's worst Municipal Bond spreads.

Note: Because of pressure from MunicipalBonds.com and increasing coverage about pricing problems in the Muni Markets, on June 23, 2003 the Muni industry finally started releasing full next-day trade reports. This includes a Municipal Bond that traded only once...or "1 trade" markets.

Because MunicipalBonds.com currently studies only same-day spread problems, the additional reporting of "1 trade" markets is not applicable to Worst Spread reports...there needs to be at least two trades to create and judge a spread.

All Information for Trade Date: 05/12/2008.

These reports represent inter-dealer and customer trades in municipal securities that have been reported by dealers to the Municipal Securities Rulemaking Board. The reports do not necessarily reflect all transactions that were effected on the specific trade date. Because of the possibility of errors in the trade submission process or errors or omissions in other processing of data, the reports should not be used as the sole basis for pricing or executing transactions in municipal securities. Prices for securities transactions vary with market conditions and can be affected by trade size and other factors.
