Theme Four: Diverging Views of Risk Among DB and DC Plans
We expect a growing realization of a divergence among investors when it comes to attitudes toward risk, driven by the way the post-pandemic environment is changing the nature of liabilities. We contend that many defined benefit (DB) funds have an incentive to de-risk, but many defined contribution (DC) funds face an imperative to increase risk levels.
The surge in bond yields over the last 12 months has helped funding ratios for DB schemes with liabilities set in nominal terms. In some cases, funds have closed funding gaps and are able to enter into arrangements with insurance companies to cover liabilities. Even when that’s not the case, higher yields will enable many of these funds to move up the quality spectrum in their asset allocations.
The outlook for DC funds, on the other hand, is very different. The shock of the past year has been the return of inflation, and adjustments still need to be made in adapting asset allocations to reflect an equilibrium level of inflation that’s above the pre-pandemic level.
This view of a divergent risk attitudes depends on the long-run prognosis for inflation from here. Taken at face value, the fall in inflation break-even rates in recent months might imply that there’s not a problem. However, we see strong reasons to believe that moderately higher inflation is here to stay—a result of deglobalization, ESG and demographics.8 For DC funds, the “liability” is the ability to maintain and grow purchasing power, because retirement costs, set in the real economy, move with inflation.
This situation will necessitate a more nuanced sense of what “risk” means. In these cases, we would argue that the primary definition of risk should be the probability that end beneficiaries run out of money in retirement. This metric should take precedence over risk measures such as the expected near-term volatility of the asset portfolio.
In recent decades, a world of low inflation and high returns from both duration and equity beta enabled these different kinds of investors to think about the world in a roughly similar way. But higher inflation, elevated discount rates and lower expected asset returns means that the difference in liabilities will accentuate the difference in approaches to risk, and hence strategic asset allocation decisions, that different types of funds take in coming years.
Embedded in the different structures between DB and DC funds is that DB funds can take an aggregate view of risk for the whole portfolio. For DC funds, risk is couched in terms of individuals, so it must be dynamic as participants age. The natures of the individual building blocks of the DC approach make it harder to take illiquidity risk. That limitation is particularly relevant, because illiquidity is one possible response to expectations for lower real Sharpe ratios on traditional investing approaches.
What are the consequences of this divergence?
Many DB funds, at least those with defined nominal liabilities, will likely accelerate their push to de-risk. For DC funds, an acceptance of a new, higher equilibrium inflation level shifts the focus to preserving purchasing power. At moderately higher inflation levels (less than 4%), equities behave like a real asset, forming a key part of a portfolio designed to preserve purchasing power, especially if there are constraints on the ability to buy illiquid real assets. We suggest that moderately higher inflation and lower expected cross-asset returns (compared to the average of recent decades) implies that DC funds should increase equity allocations across all age cohorts, and continue to hold a significant equity weight into retirement.
How should the risk of higher equilibrium inflation be controlled for older cohorts approaching and entering retirement? At higher inflation levels, bonds tend to be less effective diversifiers, so a range of assets are needed to achieve an attractive trade-off between income and diversification. We suggest a mix of real and private assets, factors, and Treasury Inflation Protected Securities (TIPS).9
The other way to offset this higher portfolio risk is to pair it with insurance structures designed to avoid the opportunity cost of forgoing investment in growth assets. An example would be a Guaranteed Lifetime Withdrawal Benefit (GLWB), a lifetime-income insurance contract purchased at or before retirement. Guaranteed income is withdrawn from the portfolio, and if the portfolio is depleted a guaranteed minimum payment is covered by an insurance payout.
From the point of view of long-term protection of purchasing power for an overall portfolio, pairing a higher-equity or real asset core portfolio with such insurance offers a way for a participant to remove longevity risk without growth opportunity cost or the return risk to beneficiaries from dying early (known as mortality risk). A system-wide rotation from DB to DC, along with resurgent inflation, will likely make such structures more relevant for a larger pool of assets.
A Final Word on Relative Demand for Stocks and Bonds
A final thought, though not really a 2023 theme, is the likelihood of a very different supply/demand dynamic for equities versus government bonds over the next five years. In short, we expect the supply of bonds to rise as demand for bonds falls (Display 11). For equities, we expect the opposite dynamic to prevail (Display 12).
Specifically, in the case of equities:
- Corporations were already the largest demand source in the decade before the pandemic, far exceeding investors’ demand. Over the past year, share buyback activity in the US has reached a new record. The current exceptional pace is unlikely to be sustained as growth slows during this cycle, but we still expect robust buyback activity.
- The flip side of the demand trend is that equity issuance has declined. Structurally, there are fewer IPOs, and there’s less cyclical need to rebuild capital in this period of low growth compared with previous recessions.
- We suggest that, as more investors adjust their strategic asset allocations to structurally higher inflation, some will need more equity exposure. This applies to investors seeking a real return, so a large swath of DC funds could be in this group. This issue isn’t the same for DB funds, but a generational DB-to-DC shift means that DC assets should continue growing in relative significance.
For government bonds, the picture is quite different:
- Issuance is likely to be higher, not just in the near term but over the longer term, too.
- We expect less demand from investors, assuming a tilt in pension assets from DB to DC, with DC requiring more inflation protection. We also expect broader recognition among investors that the diversifying power of sovereign bonds is likely reduced.
- De-dollarization means that foreign investors (especially China) will at least try to reduce their holdings of US Treasury bonds; other countries may try to diversify somewhat.
- As for the transition from QE to QT, there’s a debate as to whether it counts as net supply, given that the Fed isn’t selling, just reducing its balance sheet. At the very least, it equates to reduced demand versus recent years—even excluding it, there’s still a net extra supply of Treasuries.
