Introduction

Market risk is a key risk for most life insurers, many of whom need to manage guarantees on volatile portfolios of assets. For general insurers, the importance of market risk varies depending on the tail of the business, but investment income is a key driver of profitability and market risk encompasses variations in this income. The author’s experience is of the life insurance market in the United Kingdom, where there is a bias in coverage toward this market, but it is hoped that the points made are applicable to other insurers.

What is Market Risk?

Any framework for market risk should start from clear definitions of market risks as part of a comprehensive risk universe. There is no definitive classification of market risk per se—each company will use one that suits its needs, but the market risk classification should be suitably granular to address the many different types of risks. It should also identify areas of overlap with other risks, not least as there may be separate accountabilities for these within a firm. The actuarial profession in the United Kingdom has published a paper on risk classification (Kelliher et al., 2011), together with a spreadsheet of detailed risk categories, which may be of use in this regard.1 This defines market risk as “the risk that as a result of market movements, a firm may be exposed to fluctuations in the value of its assets, the amount of its liabilities, or the income from its assets,” and then identifies 11 high-level categories and nearly 100 subcategories of market risk.

Market Risk in Different Companies and Countries

There are wide divergences between the market risk exposures of insurers in different countries. In the United Kingdom, life insurers have exposure to guarantees which are in effect under “with-profits” policies, where part of the assets is invested in equities, effectively giving rise to an exotic put option position. Unit-linked funds offered by life insurers are a key investment vehicle for pensions. These generally contain no guarantees, with market risk borne by the policyholder, but the life insurer is exposed to fluctuations in fund-related fees. Until recently, pension funds have had to be converted into an annuity for life, and UK life insurers have substantial liabilities to this type of business, typically backed by corporate bonds to avail themselves of the liquidity premium on these (there being little need for liquidity as the annuities cannot be encashed), but this gives rise to exposure to movements in credit spreads.

By contrast, in the United States, with-profits or participatory business has evolved differently than in the United Kingdom, in part because of guaranteed surrender value requirements imposed by US regulators. Market risk exposure relates more to corporate bonds than to equities. Mutual funds rather than insurer unit-linked funds are the key vehicle for pension saving. Life insurer unit-linked offerings typically come as “variable annuities” with guarantees which are dynamically hedged. Conversion to an annuity for life is not mandatory, so this business is not as important as it is in the United Kingdom.

If we were to look at life insurance markets in the European Union and elsewhere, we would find further diversity—what is notable about market risk in life insurance is its heterogeneity between different countries.

There are further differences in the case of general insurers, which typically have a more short-term investment outlook, although certain long-tail lines of business may have a similar time-frame of investment to that of life insurers. Typically, assets held will be mainly cash and bonds, reflecting the nature of the liabilities, but some general insurers invest in equities and other risky assets to boost investment returns and profits. Indeed, one of the most famous equity investors, Warren Buffet’s Berkshire Hathaway, is primarily a property and casualty insurer.

As well as market risks relating to policy liabilities, insurers may be exposed to market risk in respect of staff pension schemes. The accounting and regulatory capital treatment of staff pension schemes may vary, but the economic risk posed by such schemes should be captured in the market risk framework. Similarly, there is an economic value associated with the value in-force (VIF) of future fund-related charges, and while this may not be reflected in accounts or regulatory capital, the market risk framework should capture fluctuations in VIF due to market risks.
