In Most Cases, Would Have Delivered Higher Account Balances at Retirement, More Guaranteed Retirement Income per Dollar, and Averaged Nearly $89,000 Larger Estate Balances
NEW YORK, January 15, 2026 – A retirement fund with part of its asset allocation to bonds replaced with an allocation to the TIAA Traditional annuity may have the potential to create better retirement outcomes and lower investment risk, according to TIAA Institute research conducted by consulting firm Charles River Associates (CRA).
This is particularly timely as January marks National Financial Wellness MonthOpens in a new window, an observance that encourages Americans to pay closer attention to their financial well-being and make resolutions for the New Year. Financial wellness encompasses not just account balances, but how individuals generate income, budget and manage their money, and plan for their future.
The research, which examines 49 years of historical data from 1973 to 2021, shows that including TIAA Traditional as a bond substitute in target-date glidepaths led to improved retirement outcomes in the vast majority of scenarios analyzed. A glidepath is a predetermined investment strategy that automatically shifts a target date solution’s asset allocation from more aggressive investments like equities to more conservative investments like bonds as the target retirement date approaches.
"As we face growing economic uncertainty, market volatility and Americans living longer in retirement, plan sponsors need solutions that can weather various economic cycles," said Kourtney Gibson, chief executive officer of TIAA Retirement Solutions. "This research demonstrates that integrating guaranteed lifetime income into target-date portfolios has never been more essential in helping both plan sponsors and their employees build truly secure financial futures."
This analysis was first published in 2015, with updates in 2022, 2024Opens pdf and last year. The 2025 update adds three years of data to the analysis and extends the examined retirement periods to 15-30 years, more closely matching experienced retirement lengths.
CRA found that, in most cases, glidepaths with an allocation to TIAA Traditional outperformed those with an allocation only to equities and bonds – yielding higher balances at both retirement and end of life and allowing retirees to generate more guaranteed income per dollar of savings. The benefits are especially notable for plan participants whose risk tolerance would lead to higher fixed-income allocations.
The study examined 27 different retirement scenarios with varying start dates and portfolio allocations. Key findings include:
- Portfolios with TIAA Traditional had more money left over in over 93% of scenarios compared to those without it.
- On average, portfolios with TIAA Traditional had balances 4.9% higher than those without it at the end of retirement.
- The average estate value was $88,879 larger in scenarios where TIAA Traditional outperformed traditional portfolios.
- Portfolios without TIAA Traditional needed to annuitize more assets to match the guaranteed income levels provided by portfolios with TIAA Traditional.
- At the end of the saving period, portfolios with TIAA Traditional had higher savings balances than did portfolios without 63% of the time; the average extra amount was $8,127.
The research is particularly relevant given recent bond market volatility. From December 2021 to December 2024, yields on 10-year U.S. Treasury Notes increased from 1.52% to 4.58%, putting downward pressure on bond prices. During this three-year period, the Bloomberg Aggregate Bond Index provided a negative 7% return, while TIAA provided retired annuitants with increases to annuity income of 5% and 3% in 2022 and 2023, respectively. TIAA Traditional account holders still working and saving gained over 11% during the same period.
“Industry-wide, there has been discussion regarding the optimal annuitization strategy: Whether the participant should wait until retirement to annuitize some of their equity and bond assets for guaranteed income – or, instead, direct some retirement contributions over time to a target date solution with an embedded annuity, for example, TIAA Traditional,” said Surya P. Kolluri, head of TIAA Institute.
“The CRA research examined both approaches – and found that an allocation to TIAA Traditional enhanced both the overall portfolio as well as the retirement income purchase,” he said. “It may also offer the potential for improved estate planning.”
“Our research shows that replacing some of your allocation to fixed income with TIAA Traditional can lower overall risk by reducing interest-rate risk and adding stable returns – while also offering the option of guaranteed lifetime income,”1 said Gibson. “Ultimately, this helps participants be better prepared for a more secure retirement”
