I think this technology is very good for finance industry. All major banks, financial institutions will want to take benefit of blockchain in the future.
And they're in the development already, so they really want the blockchain technology, to reduce their running costs (and to gain more profit as a result)... If the major insurance companies are telling that they're not working on a blockchain system, the reason can be that they're trying to cooperate with fintech companies to adopt an already developed solution (via cooperation or they're just buying the small fintech company with the patents too).
The technology will change the financial and the insurance market, the only question is the timing, but according to the fintech workshops and fintech conferences, the process has already started, slowly but surely
