Minimum Tick Increase for 30-Year U.S. Treasury Bond Futures Effective on Sunday, August 30, 2009 - ** INFORMATION UPDATE**

Effective Sunday, August 30, 2009 (trade date Monday August, 31), the minimum trading tick for 30-Year U.S. Treasury Bond outright futures will be increased from the current ½ of 1/32^nd  to full 1/32^nd (from $15.625 to $31.25). The minimum trading increments for futures intermonth and intercommodity spreads, as well as options, will be unchanged. This tick increase does not impact any other Treasury futures contracts.

As a result of the tick size change, CME Group will modify the T-bond futures settlement procedure for Friday, August 28, 2009. In order to ensure that Friday settlement prices are in increments of a full 1/32nd , CME Group will calculate outright contract settlement prices by applying current settlement procedures and rounding them to the nearest 1/32nd price increment.
