ICE Futures U.S. amended its Block Trade guidance to authorize block trades for two ICE exchange inter-commodity strategies where one leg includes an ICE Futures U.S. energy contract and the other leg includes an ICE Futures Europe energy contract and the sum of the quantities of the two legs exceeds the minimum threshold for block trades for the IFUS product. This relief is not available where one leg of a multi-exchange strategy involves an IFUS energy product and the other leg is an energy product on any exchange other than ICE Futures Europe, even if the two legs are highly correlated.
