Markets require mass transparency to get even a few people to have a dialogue on substance based on numbers. This requires a population of millions to generate a substantive discussion by even a few people.
Derivatives data that is hidden behind expensive firewalls means the derivatives market is not transparent. This means the prices are not fair. The gap from fairness can reach extremes and then there is a crisis.

I don’t think anyone thinks derivatives are transparent. And, so, many people won’t trade derivatives because of lack of public data and lack of a public market. Faye Albert
Thanks for commenting. I agree. People in companies need to do more public comment on what they are doing and how they are doing it.
