1. Defending against the bogeyman: Inflation
After lying dormant for much of the past 30 years, global inflation is clearly back. How might the growing threat of higher (and potentially “stickier”) inflation impact plan participants’ ability to achieve a comfortable retirement?
For starters, longevity risk (i.e., the risk of participants outliving their retirement assets) is a key issue to be aware of, especially with average life expectancies having increased from previous generations. DC plan sponsors should consider the insidious and very real risk that inflation may pose to their participants’ plan assets – and thus, to their retirement security – over a period of years. Even modestly higher rates of inflation can lead to meaningful erosion of a portfolio’s purchasing power over time, further raising the longevity risk facing retirees.
The potential drag on portfolio return potential is evident in the equity market, where persistent inflation can exert pressure on market valuations, as shown in Figure 1. The chart plots the market’s trailing price/earnings (P/E) ratio (vertical axis) against trailing three-year headline inflation (horizontal axis), divided into five periods distinguished by differing degrees of inflation volatility. Key takeaways include:
- Higher levels of inflation, regardless of its volatility, tend to be associated with lower equity market valuations.
- Similarly, environments characterized by more volatile inflation also generally imply lower equity market valuations.
- Bottom line: Both the inflation level and the volatility of said inflation can erode a portfolio’s expected long-term returns – a kind of “double whammy.”
