The Chicago Board of Trade and the New York Mercantile Exchange fined and suspended from trading Ho Ming Yu for executing numerous buy and sell trades in the same futures contracts in two accounts he owned during November and December 2012. The purpose, claimed the exchanges, was tax-related. Mr. Yu was alleged to have engaged in matching buy and sell transactions involving 772 futures contracts on the CBoT and 1,561 contracts on NYMEX. Mr. Yu settled these disciplinary actions by agreeing to pay a fine of US $10,000 to CBoT and US $15,000 to NYMEX, and being suspended from all trading access to CME Group exchanges for 25 business days.
