>The volume of futures trading fell by 98% and the options trading market disappeared

You have to wonder what the second-order effects of the options trading market disappearing (or being severely reduced in volume) would be.

I know there are some pretty important businesses that depend on options to hedge against commodity prices. Airliners and oil come to mind.

i would say getting rid of this market makes the financial system healthier. 2008 crash could have been avoided with something like this

Would it? It wasn't options trading that caused 2008; it was bad home loans.

yes. the derivatives built on top of bad home loans caused the contagion. it would have been close to a non-event if there were no derivatives based on the bad homeloans.

The derivatives were traded in massive blocks, not in high-frequency transactions where fees adding up matters.
