The CME Group has increased margin requirements on U.S. government debt futures and other products linked to U.S. Treasuries, Financial Times reports. The margin changes by CME cover new trades along with current positions and became effective at the close of trading on July 25, 2011.

The cost of trading 10-year U.S. Treasury futures for hedging purposes will increase to $1,300 from $1,100. It has adopted the defensive measures after an impasse in Washington over raising the Federal debt window.
