The CME Group (CME), the world's largest futures exchange by volume, announced Monday that it has raised futures margins, or funds held back by traders to guarantee their transactions, for a range of oil contracts, following a review of market volatility.

"As per the normal review of market volatility to ensure adequate collateral coverage, the Chicago Mercantile Exchange Inc., Clearing House Risk Management staff approved (revised) the performance bond requirements" for several oil contracts, it said in a statement on its website.

The new rates will be effective from the close of business on Tuesday, May 10, it said.

Products included in the change include New York Mercantile Exchange West Texas Intermediate and Brent crudes and gasoline and fuel oil contracts.

A sharp run up in oil prices in recent weeks, followed by a sharp fall last week has been blamed by many market watchers on speculative activity not directly related to market fundamentals.

In recent weeks, Nymex crude reached a high of $114.83 per barrel. At 0321 GMT Tuesday it was trading at $100.80 a barrel, down $1.75.
