(Kitco News) - Margins needed to trade Comex silver futures are being increased by the CME Group and will take effect after the close of business on Tuesday, the exchange said Monday in a press release.
The move by the CME Group to raise the margin needed to trade – also known as performance bonds – silver futures on the Comex division of the New York Mercantile Exchange likely won’t come as a surprise given the heavy volume and more than $4 an ounce price swing in the metal on Monday. Futures traders had talked about the possibility this would occur because of Monday’s volatility. The CME Group is the parent company for the Comex and Nymex.
