Are We Heading Toward a Reinsurance Bubble?
As a topic, “shadow insurance” may have a certain MEGO quality — that’s “My Eyes Glaze Over” — but a new paper called “Shadow Insurance” (abstract; PDF) by Ralph S.J. Koijen and Motohiro Yogo is well worth a look:
Life insurance and annuity liabilities of U.S. life insurers were $4,068 billion in 2012, which is substantial even when compared to $6,979 billion in savings deposits for U.S. depository institutions (Board of Governors of the Federal Reserve System 2013). However, there is little research on life insurer liabilities, especially in comparison to the large banking literature. The reason, perhaps, is the traditional view that life insurer liabilities are safe (and boring) because they are more predictable, longer maturity, and less vulnerable to runs. Hence, all of the interesting action is on the asset side, where life insurers take on some investment risk. This paper shows that developments in the life insurance industry over the last decade shatters this traditional view. As a consequence of changes in regulation, life insurers are now using reinsurance to move liabilities from operating companies that sell policies to less regulated and unrated shadow reinsurers. These shadow reinsurers are captives or special purpose vehicles in U.S. states (e.g., South Carolina and Vermont) or offshore domiciles (e.g., Bermuda, Barbados, and the Cayman Islands) with more favorable capital regulation or tax laws. In contrast to traditional reinsurance with third-party reinsurers, there is no risk transfer in these transactions because the liabilities stay within the same holding company.
