Since the claims were increasing due to death, disability or stress, the premiums collected were falling short resulting in losses.

He added “There is plenty of evidence of insurers and reinsurers suffering considerable losses from this and it is a reality that wholesale insurance prices were simply too low in the past. Some of these claims are driven by the tighter economic environment. It is marvelous to see Australians gaining great value from their life insurance protection but it does need to be appropriately structured and priced.”
He also expressed concern that “Pricing was more sustainable pre-GFC but in recent years the industry has experienced a significant increase especially in disability-related income protection claims, often stress related.”
He summed up the issue stating that life insurance and superannuation industries would have to jointly search for methods of stable pricing in the long term
