There are a vast number of use cases here. A simple one is the peak mortgage rate market[1]. That allows you to create hedges against movement on variable rate homeloans directly.

There's a number of unemployment-related markets that allow you to create insurance for yourself against unemployment.

And these are just things I've thought up of in a couple of minutes, not even considering what actual financial markets might want to use them for.
