CME CEO Terry Duffy said he is "very concerned" about the rise of so-called
perpetual futures, a contract type that recently received key approval from US
regulators. He said the products have little practical use for institutional
investors while creating excessive risk exposure for retail traders and added,
"I have serious concerns about the contract design. I don't want people who
don't understand the product to be forced out by liquidations; they shouldn't be
in these contracts."
