Is continuing illiquidity in the life/annuity portfolio a cause for concern?

By Mary Pat Campbell

With results from 2023 investments for both life/annuity and property/casualty insurers in, we see life/annuity insurers continue to reach for yield through illiquid assets, such as mortgages and private placements.

Property/casualty insurers, in contrast, have increased their cash and short-term bond holdings, maintaining their relatively high liquidity position.

In general, given the longer duration of life liabilities, life insurers have been taking on more illiquid profiles in their asset portfolios. However, as interest rates rise, this may put the squeeze on insurers as the market value of fixed rate assets decreases in response and as policyholder behavior responds to the changing environment.

Increased surrenders in face of rising interest rates and challenging economics

Policyholder behavior can have a large effect on life/annuity results, especially when it comes to surrenders. Although some product features reduce the impacts of policyholder options, such as surrender charges or market value adjustments, many of the most popular products in the life/annuity industry, especially in individual annuities, have policyholder options that can create disintermediation risk as policyholders exercise them.

Surrenders increase not only as policyholders cash out of products to use the cash for present needs, but also when exercising guaranteed minimum withdrawal benefits on annuities or surrendering old life insurance policies or annuities to roll over into new products with better features. As interest rates have risen, some traditional products have become more attractive with better crediting rates. New product designs such as registered index-linked annuities or registered indexed universal life have also provided higher upside potential accumulation for customers, attracting certain market segments that may already own life-annuity products.

These increased surrenders create cash flow demands on insurers. If incoming cash flows do not cover surrender cash flow demands, assets must be tapped. More than 90% of the life/annuity general account portfolio is fixed income in nature, leaving a potential loss in value from interest rate risk. However, there is additional liquidity risk as life/annuity insurers have been increasing the illiquidity of their portfolios.

Increasing illiquidity of the life/annuity bond portfolio

Life/annuity insurers have been shifting to an increasingly illiquid profile in their asset portfolio across many asset classes, but the most notable shift can be seen in the bond portfolio.

Private placements and 144(a) bonds have increased their share of the life/annuity bond portfolio to the extent that public bonds have decreased from 75% of the bond portfolio in 2009 down to 56% of the portfolio in 2023.

Both types of nonpublic bonds have increased their share in the portfolio as life/annuity insurers sought yield in bond types such as collateralized loan obligations and eschewed low-yielding government bonds. In some cases, insurers may have sought more credit protection in private placements. Private placements have been shown to have better credit loss experience in the Society of Actuaries’ experience studies covering 2003-2015, when compared to similarly rated public bonds.

However, one dimension on which private placements are less desirable than public bonds or even rule 144(a) bonds is liquidity. If insurers need to sell private placements before maturity, they may not get the full economic value of their asset or need to incur high transaction costs in time or money.

Increasing mortgage holdings another source of illiquidity

The other allocation issue for life/annuity insurers is mortgage holdings. Most of the mortgages (whole loans, as opposed to mortgage-backed securities, held in the bond portfolio) are for commercial real estate, such as office buildings or hotels.

Mortgage holdings as a percentage of investable assets has been increasing since 2010, when it had been at a low of 10.2% of the portfolio. There had been a fairly steady increase in allocations until the pandemic, leading to a small dip in 2020, but allocations began rising again in 2021 and stood at 15% at the end of 2023.

Mortgages have been seen as a way to achieve extra yield in a low-rate environment, but that advantage has eroded, at least in book yield terms. As interest rates have increased, the book yield on the bonds invested in by insurers have increased, more rapidly than the yields on mortgages. In addition, impairments on mortgages have increased.

Impairments further affect the liquidity of the assets, as well as the investment income to be realized in the portfolio. These impairments in 2022 and 2023 came before any official recessions and would likely increase in the case of a recession.

Allocation shifts differ by insurer size

While talking about liquidity of assets more generally, not all these concerns are shared equally over the life/annuity industry. Asset allocations differ greatly between insurers, and one of the dimensions where distinctions can be seen most clearly is by size. The largest insurers are most likely to have the highest allocations to mortgages.

The largest life/annuity insurers have invested more in illiquid assets, such as private bonds and commercial mortgages, than have smaller insurers. These assets may require special management in times of economic stress, but they may also offer higher returns and match more complex liabilities. However, these strategies may face challenges when interest rates rise.
