FCStone Group, Inc. Key Monthly Performance Metrics for May 2009

KANSAS CITY, Mo., June 24, 2009 (GLOBE NEWSWIRE) -- FCStone Group, Inc.
(Nasdaq:FCSX), a commodity risk management firm, today reported key monthly
performance metrics for May 2009, as follows:

* OTC volume (in thousands) of 24.8 contracts, compared to 30.8
contracts in April 2009 and 114.0 contracts in May 2008;
* Exchange-traded contract volume (in thousands) of 4,573.8

Please note that effective with today's release, FCStone is reporting customer
segregated assets on a monthly average balance basis. Prior releases included
the balance as of the prior month end. While the month-end balance is the metric
required for regulatory reporting purposes, management believes a monthly
average provides a more representative picture of monthly fund flows and client
account activity.

FCStone's release of selected monthly performance metrics is designed to provide
more transparency into the ongoing dynamics of FCStone's operating environment
during the above-referenced time period. The reported performance metrics may
fluctuate significantly from month to month and therefore are not necessarily
indicative of the quarterly or annual financial performance of FCStone. In
addition, other factors not reflected by the performance metrics may have
significant effects on FCStone's financial performance.
