Hostilities between U.S. futures exchanges and banks that offer  privately negotitated derivatives contracts burst into the open again   Wednesday at a Congressional hearing on the Commodity Exchange Act.   
Patrick H. Arbor, chairman of the Chicago Board of Trade, used the forum  to urge the Senate Agriculture Committee to "eliminate the opportunity" for   the derivatives dealers "to escape" the jurisdiction of the act.   
  
At issue is the exemption that privately negotiated transactions have  from regulation. Thanks in part to this so-called Treasury amendment to the   act, volume in the over-the-counter derivatives has ballooned to an   estimated $40 trillion worldwide.     
The futures exchanges say the exemption establishes an  uneven regulatory landscape that unfairly favors the over-the-counter   market.   
  
Mr. Arbor testified that a pending Supreme Court decision on whether the  exemption should be extended to government securities and currency futures   could be the death knell for the industry, if the decision goes against   the exchanges.     
"You won't have to worry about the quality of our exchange's audit trail  or financial surveillance mechanisms, because there won't be enough trades   on the (Board of Trade) to need an audit trail or financial surveillance,"   he testified. "And you won't have to worry about reauthorizing the   (commodity commission), because it will have few viable markets to   regulate. This committee's jurisdiction over the (commission) and its   markets will evaporate."           
Jack Sandner, chairman of the Chicago Mercantile Exchange, said the  exemption has led to other problems as well. 
  
"Unregulated bucket shops, Internet dealers, and even the retail trading  desks of currency dealers are taking advantage of the public, evading the   intense regulation mandated for futures trading and shiphoning liquidity   away from the markets," Mr. Sandner told the committee. "Because the   Treasury amendment is most abused by currency dealers, the (Mercantile   Exchange) has borne the greatest competitive burden in consequence of the   regulatory disparity."           
The futures officials' comments came just after the major exchanges  reported a continued trading slide in financial and interest rate products.   Both Chicago exchanges reported double-digit volume declines during May,   and both have reported declines in year-to-date volume.     
But dealers in the over-the-counter derivatives markets counter that the  exchanges shouldn't be complaining, because they are performing well.   During the same period that the Mercantile Exchange was   reporting a decline in trading volume, it reported consecutive records   in open interest, on May 31 and June 3.       
"If you look at the statistics, you see the exchanges continue to grow  every year," said Gay Evans, chairman of the International Swaps and   Derivatives Association, the main trade group for derivatives dealers.   "Continued growth in over-the-counter derivatives and continued growth in   futures is complementary and should be viewed as such."       
  
The futures industry is proposing that the committee adopt seven changes  to the act to overcome these problems. Among the proposed changes, the   industry would like to see the exchanges receive "fair and evenhanded   treatment on exemptions." It also wants the committee to refine the   Treasury amendment to eliminate the opportunity to escape the commission's   jurisdiction.
