Managing Inflation Within Target Date Strategies

Inflation is a significant, though often overlooked risk, that can devastate retirees’ purchasing power. Building a plan today helps to buffer from unpredictability tomorrow.

Target retirement strategies continue to grow as a leading default vehicle, offering professionally managed, age-appropriate portfolios that automatically rebalance in order to keep participants on target. However, there are key differences between providers in how each strategy manages key investment risks as they evolve in importance for participants at each stage of their careers. For young employees entering the workforce, wealth accumulation is the key goal. For those approaching retirement, this fairly straightforward goal is replaced by competing objectives. Soon-to-be retirees need to preserve accumulated wealth while also maintaining enough exposure to growth to address longevity risk — i.e., the risk of running out of money in retirement. But a well-designed target retirement strategy needs to do more than just account for wealth preservation from market volatility; it should also seek to preserve investor purchasing power from the corrosive impact of inflation. Thoughtfully balancing these key investment risks by delivering efficient portfolios while being mindful of potential negative shocks is crucial in seeking to deliver successful retirement outcomes.

A Recent History of Inflation

Inflation has been largely contained for some time, but a longer view of American history illuminates the severity of this risk. For example, the average investor would have been worse off retiring in 1966 at the beginning of the Great Inflation than at any other time in American history — including the Great Depression. Driven in part by policies aimed to promote economic stability, inflation skyrocketed from above 1% per year in the early 1960s to higher than 14% in 1980.i  Retirees drawing down on their savings while investing in a diversified mix of stocks and nominal bonds would have lost more than 70% of their purchasing power during this period, severely compromising their ability to spend in retirement.ii  The Great Inflation offers a cautionary tale about the impact unexpected inflation can have on portfolios, underscoring the importance of structurally addressing this risk for the subset of participants most vulnerable to its effects.

Today’s Inflationary Environment

While such hyperinflation is less of a concern today, the current inflation outlook is more complex than it has been in quite some time, and inflationary risks are reemerging. The US Consumer Price Index (CPI) has surged to its highest level in nearly 13 years after May’s headline CPI showed an annual rise of 5%, and investors may soon find themselves vulnerable to a sustained move higher in inflation.iii In order to protect their purchasing power, investors should consider making an allocation to inflation-hedging assets, due to their strong historical performance during inflationary periods.

Today, both one and three year forward looking inflation uncertainty as measured by the New York Fed’s Survey of Consumer Expectations have spiked to match their highest levels since the survey’s inception in 2013. As COVID-19 vaccine distribution continues, economies will continue to advance their reopening efforts, and people will begin traveling, shopping, and dining en masse again, exercising what has been more than a year of pent-up demand. But low inventory due to manufacturing shutdowns, agricultural interruptions, and frozen supply chains could upset the supply-and-demand balance and set the stage for inflation to overshoot expectations.

Figure 1: Inflation Uncertainty

Given the uncertain future of both realized and expected inflation, and the risk that inflation poses to investors, we believe that an important strategic objective of the glidepath should be to mitigate the potentially negative impact rising inflation has on a portfolio. In seeking to carry out this objective, two questions need to be answered in order to build an effective inflation-sensitive allocation: (1) When is it most appropriate to include an inflation-hedging allocation, and (2) what is the appropriate mix of asset classes to hedge inflation?

Applying Inflation Hedging: Time Horizons

First, where would this allocation be most appropriate in order to improve outcomes? Over long time horizons, traditional asset classes (primarily stocks) have delivered strong returns, suggesting that an effective way to offset inflation over the course of a participant’s career is a meaningful allocation to stocks. However, this relationship only holds up during periods of subdued to moderate inflation, and as time horizons shorten, traditional asset classes may not be a suitable hedge. Looking back over nearly 50 years, we can observe that stocks and nominal bonds have delivered negative real returns in periods of rising inflation. For those retirees seeking to use their accumulated wealth to purchase goods and services in retirement, the potential for negative real returns from traditional asset classes can be especially corrosive. For those older participants, a meaningful allocation to inflation-sensitive asset classes takes on outsized importance.

Applying Inflation Hedging: Asset Allocation

Second, what is the appropriate mix of asset classes? An allocation to real assets can provide inflation-hedging potential, diversification to traditional stocks and nominal bonds, and a source of returns. Treasury inflation-protection securities (TIPS) are an obvious place to begin, but an inflation-protection strategy that focuses solely on TIPS won’t accomplish our objective in the most efficient manner or enable us to maximize growth.

In a rising inflationary environment, TIPS will provide inflation protection and perform better than their nominal bond equivalents, but they will likely generate returns that are less than desired as an inflation hedge. Because TIPS are indexed to inflation, their principal adjustments are backward-looking by nature, and as such they tend not to perfectly hedge unexpected inflation. Shifting exposure to a shorter-duration TIPS index can potentially mitigate interest rate volatility and better align with future inflation expectations as shorter duration bonds tend to have a stronger, more positive relationship with inflation. The State Street Target Retirement strategies feature an 18% allocation to Intermediate TIPS in retirement.

Rather than limit our approach to this one core exposure, our strategy instead seeks to create a more efficient inflation protection basket by complementing an allocation to TIPS with additional asset classes such as commodities and real estate investment trusts (REITs). This approach can offer inflation-management benefits at different points within the economic cycle, along with potentially higher long-term return expectations (see Figure 3). Historically, commodities have performed best during periods of rising inflation or unexpected inflation. They have exhibited a strong beta and correlation to inflation, due to their ability to reprice quickly based on economic conditions and shifts in supply-and-demand dynamics. Thus, a small allocation to commodities can be used advantageously to help protect purchasing power and provide portfolios with insulation from unexpected inflation. And REITs have demonstrated the ability to perform well across all three inflationary regimes, particularly during periods of stable and rising inflation, due to pass-through effects where REITs can adjust rents and pass along price increases to tenants. In aggregate, this inflation-hedging strategy allows State Street to meaningfully address inflation risk within the context of the other key risks that participants are facing — accumulation, volatility, and longevity — rather than viewing the problem in isolation.

Our approach to balancing key risks has resulted in a consistent level of peer-relative performance in our retirement vintage over time. The idea is to not significantly outperform in any one market environment while exposing investors to expected underperformance in others, but rather to provide a well-diversified mix of investments that can address the key risks that participants face. As testament, the State Street Target Retirement Income fund has outperformed 81% of its peers since its inception in 2005v, delivering a consistent history of strong peer-relative performance across a range of market environments.

Considering the Core

Inflation-hedging options have become increasingly prevalent on core menus, allowing do-it-yourself participants to address this key risk through asset classes beyond traditional stocks and bonds. However, investing in inflation-sensitive asset classes on a standalone basis exposes investors to a number of potential issues that may be mitigated through a multi-asset solution. Many plans today offer TIPS funds as a potential inflation hedge, which exposes investors to varying levels of interest-rate risk and may not provide the desired level of sensitivity to unexpected inflation. Further, asset classes like commodities and REITs, which often improve portfolio efficiency in a multi-asset framework, feature considerable volatility on a standalone basis. A multi-asset approach to real assets may be a more appropriate option for plan sponsors seeking to address inflation on the core menu.

State Street offers core menu investors a seasoned, diversified multi-asset strategy composed of a blend of commodities, TIPS, REITs, infrastructure, and natural resource equities. This multi-asset approach, featuring the diversification benefits of five distinct asset classes, allows the strategy to seek a positive real-return in excess of CPI over a full market cycle, similar to the long-term return expectations of a moderate balanced portfolio with a volatility profile in line with a longer-dated TIPS index.

The Real Asset Strategy is expected to perform best during periods of increasing inflation or rising unexpected inflation. The strategy is meant to be a complement to traditional equity and bond assets, providing further diversification, attractive returns, and a source of income in a low-yielding environment.
