Inflation Risk

Inflation is the general increase in prices for goods and services over time, which reduces the purchasing power of each dollar you hold. Inflation risk, also called purchasing power risk, is the possibility that the returns on your savings and investments will not keep pace with inflation, resulting in a decline in your real (inflation-adjusted) standard of living.

The long-term average annual inflation rate in the United States has been approximately 3%, though it has varied significantly from year to year. At a 3% annual inflation rate, the purchasing power of $100,000 is reduced to roughly $74,000 in 10 years and about $55,000 in 20 years. For retirees planning for a 25 to 30 year retirement, inflation can effectively cut the value of a fixed income stream in half or more.

Certain categories of expenses that are particularly relevant to retirees, such as healthcare and long-term care, have historically experienced inflation rates higher than the general consumer price index. This means retirees may face an even greater inflation challenge than the headline numbers suggest. Housing costs, property taxes, and insurance premiums may also rise at rates that outpace general inflation in certain markets.

Strategies to manage inflation risk may include maintaining an allocation to stocks and other growth-oriented investments that have historically outpaced inflation over long periods, considering Treasury Inflation-Protected Securities (TIPS) or I Bonds that adjust for inflation, delaying Social Security benefits (which receive annual cost-of-living adjustments), and ensuring your withdrawal strategy accounts for rising expenses over time.

Cash and fixed-income investments, while providing stability, are the most vulnerable to inflation risk. A retiree holding a large portion of their portfolio in cash or bonds with fixed interest rates may find their purchasing power declining steadily. Balancing the need for stability with the need for growth is one of the central challenges of retirement income planning, and inflation risk is a primary reason why maintaining some equity exposure throughout retirement may be important.
