Analysis of Economic Scenarios Used by Huggins Actuarial Services, Inc. 2016 through 2018
OVERVIEW
When Huggins’ actuaries create an Economic Capital Model, they use a state-of-the-art modeling platform designed by actuaries and other insurance professionals that is widely known as an industry standard. These models are used to predict profits, policyholder surplus, income and other financial metrics over a pre-determined timeframe. In order to reflect uncertainty in the future economic activity which affects balance sheet assets (stocks and bonds), Huggins loads Economic Scenarios into the Economic Capital Model. The Economic Scenarios used by Huggins are generated by a top flight firm that specializes in the analysis of industry trends. In the tables below, Huggins actuaries analyze how these economic scenarios for four classes of assets have been changing over the period 2016 to 2018:
- Corporate A-Rated Bonds;
- Blue Chip Stocks;
- Master Limited Partnerships (“MLP Equities”); and
- Treasury Bonds.
In the analysis for each category of asset, the actuaries consider yields for bonds and total returns for stocks and MLPs using the future forecasts given by one-year time-step (one year in the future), three-year time-step (three years in the future) and five-year time-step (five years in the future) scenarios. Each scenario consists of 10,000 random values generated by the Economic Scenario Generator. The yield and total return data are fit to a normal distribution and the following are derived:
- Distribution Mean and
- Distribution Standard Deviation.
SUMMARY OF RESULTS
Overall, the yields for bonds and total returns for blue chips stocks and MLP equities increase over time, both as time-step increases and going from the 2016 economic scenarios to the 2018 economic scenarios, reflecting both increasing bond yields and increasing inflation.
What do these increases in bond yields and total returns mean for an insurance company? The impact depends on the asset mix of the current portfolio and the result is likely to be mixed. Given that most property casualty companies invest heavily in bonds, the embedded bonds are likely to decrease in value as bonds are marked to market. The increase in bond yields for newly purchased bonds will offset this downward adjustment somewhat. The non-bond portion of the portfolio should have a larger contribution to the bottom line than in the recent past in both dividends and enhanced asset value. Overall, Huggins would expect to see increased investment returns, possibly returning to pre-recession levels.
ANALYSIS BY ASSET CLASS

For five-year “A” rated corporate bonds, the yields increase from 2.13% for one-year time-step to 3.97% for five-year time-step for the 2016 economic scenarios, to 3.59% for one-year time-step to 4.71% for five-year time-step for the 2018 economic scenarios.
