Bond Futures at Risk From Rapid Hedging Overhaul as Yields Climb

Global Bond Selloff Deepens, US 30-Year Hits '07 High

Traders of CME Group Inc.’s futures contracts, especially those that track the Treasury’s longest-maturity bond, are at risk as rising oil prices stoke concern about inflation, sending yields higher. The US 30-year’s topped 5.1% on Friday, the highest level in about a year.
