Options Industry Sets New Daily Volume Record Surpassing 25.3 Million Contracts On Tuesday, July 15

CHICAGO, July 16, 2008 - The Options Clearing Corporation (OCC) announced that a new daily trading volume record was set on Tuesday, July 15, 2008 when 25,264,883 contracts were traded, 6.4 percent higher than the previous record of 23,745,650 contracts set on August 16, 2007.

Equity options trading set a new record with 22,941,369 contracts, a 10.7 percent increase over the previous record of 20,730,201 contracts on November 8, 2007.

"Options trading volume typically rises with volatility and yesterday's spike in volatility came on top of higher than average trading over the past few weeks," said Michael E. Cahill, OCC President and Chief Operating Officer. "OCC's rigorous capacity planning allows us to smoothly process such a peak day—one that was twice the volume of the average day last July."
