Uncertainty reigns in the derivatives market as regulators on either side of the Atlantic debate upcoming risk management regulations, but this has hardly slowed the growth of the industry. The New York Stock Exchange reported it experienced substantial growth in June from the year before.

Last month, NYSE Euronext saw 8.8 million derivatives contracts worldwide, up from a little more than 8.1 million in June 2010. The biggest gains came in the U.S. equity options and European fixed income derivatives, which rose 19.7 percent and 14.3 percent, respectively. Though a smaller portion of its total operations, NYSE Liffe trading increased by a staggering 504.6 percent, as the exchange became the sole listing for MSCI index-based futures.

Despite the sizable gains elsewhere, European derivatives as a whole fell 2.1 percent from last year, though clearing services rose by 4.8 percent.

Still, most derivatives categories declined from their recent peak this past May, though commodities derivatives were a conspicuous exception, rising 50.6 percent from last June and 14.6 percent from May.

NYSE has seen substantial growth in its derivatives trade, but pursued a merger with Deutsche Boerse in hopes of seeing more rapid expansion.
