The Trump administration is hollowing out regulations to the benefit of industries across the board, delivering on a central campaign theme. When it comes to insurance, however, there is only so much that Washington officials can do. State insurance commissioners continue to wield the most regulatory power, and are expected to act “aggressively” in 2018, said Howard Mills, global insurance regulatory leader for Deloitte. “The state insurance regulatory structure is back to being largely the only game in town and they’re moving ahead pretty aggressively on everything, whether it’s cybersecurity, consumer protection, use of big data,” Mills said.
