Kiran Stacey Your chance to quiz the CME Group

Firstly, an apology. We are still not ready to publish the Q&A session with Josh Fox. I will publish an update with a full explanation tomorrow (Tuesday), but for now, thanks for your patience.

While we wait for Josh’s answers, please start sending in your questions for Terry Duffy (pictured right) and Craig Donohue (pictured left), the chairman and CEO of CME Group, respectively.

The Chicago Mercantile Exchange is the home of the flagship WTI oil contract, and Duffy and Donohue are perfectly placed to answer all your questions about oil pricing: from why the spread between WTI and Brent is so high; to the possibility of a brand new flagship conquering the market; to what role speculators have played in pushing it up so high.

The deadline for questions is Sunday, February 20th, and their answers will be published on Friday, February 25th.
