Target Date Glidepaths Are Broken for 2026 Retirees
The 2022 TDF drawdown revealed a structural flaw in age-in-bonds glidepaths. FC proposes a TIPS-plus-cash sleeve adjustment for late-stage 401(k).
Target date funds are the quiet default of American retirement. Roughly 60% of 401(k) participants land in a TDF by default under the QDIA safe-harbor rules, and total TDF assets in US defined-contribution plans sit around $3.5 trillion. They solved a generational default-investing problem: before TDFs, plan participants were stuck in money-market funds, concentrated employer stock, or nothing at all.
This post is not an argument to abandon target date funds. It is an argument that the standard glidepath, the “age in bonds” rule that dominates industry product design, was built for a bond-equity correlation regime that no longer exists in 2026. For a 62- to 68-year-old participant facing sequence-of-returns risk, the current glidepath is, in our view, not the optimal landing zone.
Target Date Funds in 90 Seconds
A target date fund is a single diversified mutual fund that automatically rebalances toward more conservative allocations as a target retirement year approaches. A 2025 vintage fund today holds roughly 50% equity and 50% fixed income. A 2060 vintage holds roughly 90% equity. The fund “glides” from aggressive to conservative across the participant’s working life.
The promise is set-and-forget: one ticker, professional rebalancing, age-appropriate risk. The dominant providers (Vanguard Target Retirement, Fidelity Freedom, T. Rowe Price Retirement) all use variations on a classic age-in-bonds glidepath: the equity allocation declines roughly linearly from the 2060 vintage through the 2025 vintage and stabilizes for the “through retirement” tail.
The 2022 Problem
In 2022, the Vanguard Target Retirement 2025 fund (VTTVX) lost approximately 16% of its value. The 2030 vintage lost about 16.5%. The 2045 vintage lost about 17%. The 2060+ vintages lost about 17.5%.
Look at that carefully. A 2025 vintage fund, designed for a participant within months of retirement, lost nearly as much as a fund designed for a 27-year-old with a 40-year horizon. The “safe” glide did not protect near-retirees because the usual source of downside protection, the bond sleeve, was losing money at roughly the same rate as the equity sleeve.
Bond-equity correlation over the 2000 through 2021 window averaged approximately -0.25 per BlackRock Investment Institute research. From 2022 through 2025 it averaged approximately +0.35. That is a sign change. The bonds that were supposed to cushion the equity drawdown were instead selling off alongside it because the underlying macro driver was not a growth scare (which typically pushes bonds up) but an inflation surprise (which pushes them down).
For a 64-year-old participant in the 2025 vintage fund, a 16% loss in the final accumulation year is not just a number. It is a materially worse starting point for every sequence-of-returns calculation that governs withdrawal sustainability through a 30-year retirement.
Why Age in Bonds Was Built for a Different Era
The age-in-bonds heuristic codifies an assumption that bonds are the low-correlation complement to equity. That assumption held through the post-1990s disinflation window. When the Fed was the dominant macro actor and inflation was stable near target, equity drawdowns were growth scares and bond yields fell as a result. Fixed income really was the diversifier.
In an inflation-surprise regime, both legs of a stock-bond portfolio sell off in tandem. That is not a glitch; it is the mechanical response of long-duration assets to a higher discount rate applied across the board. The 2022 through 2024 period was a case study. The forward question is whether 2022 was a one-off or whether we are in a new regime.
We will not answer that question definitively here. In our view, the right framing is not a bet on which regime dominates but a portfolio construction that is robust across both. That is what the standard TDF glidepath is not.
Sequence of Returns: What Actually Matters Five Years Before Retirement
The finding behind the classic William Bengen 4% study and the extensive Kitces work on sequence risk is that losses in the first five years of retirement (or the last five years before retirement) cost a multiple of the nominal dollar loss. A 20% drawdown in year one of retirement costs approximately nine years of portfolio life compared to the same loss 30 years later. The math is not symmetrical across the retirement window.
The standard TDF glidepath addresses this risk with a lower equity allocation at the target date, typically 50% to 55%. We believe that is a necessary but insufficient adjustment. The remaining 45% to 50% sits in a fixed income sleeve that, under inflation-regime correlation conditions, is not providing the diversification the portfolio needs.
FC’s Proposed Adjustment: Add TIPS + Cash Sleeve
Our preferred framework for the 10-year pre-retirement window is a glidepath that carves out a portion of the fixed income sleeve for explicit inflation protection and for cash. An illustrative adjustment:
- Standard TDF 2025 vintage: 50% equity / 45% nominal bonds / 5% short-term reserves
- FC-adjusted illustrative: 50% equity / 30% nominal bonds / 10% TIPS / 10% short-term reserves
The 10% TIPS sleeve handles the inflation-correlation problem directly. Treasury Inflation-Protected Securities have a principal that adjusts with CPI, and the sleeve’s dollar value does not compress under the same mechanics that push nominal bonds down during inflation surprises. The 10% cash sleeve provides a drawable reserve that can fund the first two to three years of retirement withdrawals without forcing equity sales during a drawdown.
This is not original to us. Both BlackRock and academic retirement-income research have argued for similar adjustments for years. The difference is that most mainstream TDFs have not implemented structural allocations of this shape in the glidepath tail.
What a 401(k) Participant Can Actually Do Today
Most 401(k) plans do not allow participants to customize the TDF. The practical lever set is narrower:
- Review your plan’s menu for a standalone TIPS fund and a stable value or money market fund. If they exist, a participant can hold the TDF as a core and layer a 5% to 10% TIPS or cash overlay on top.
- Consider shifting partially from the default TDF to a more conservative custom allocation during the final five years before retirement. This is a behavioral trade-off: the custom allocation requires the participant to manage the rebalancing themselves, which is a real cost.
- Use non-retirement accounts for the cash sleeve if the 401(k) is inflexible. After-tax savings outside the plan can serve the same sequence-risk function and preserve the TDF’s default simplicity inside the plan.
- Ask the plan sponsor for a through-retirement custom TDF or a managed account option. Larger plans increasingly offer these.
In our view, the right answer for the average 60-year-old participant is not to fire the TDF but to understand what it is doing and to supplement it on the margin with a small TIPS-plus-cash overlay sized to the participant’s actual cash need in the first years of retirement.
In Our View
Target date funds solved a huge default-behavior problem, and they continue to solve it elegantly for accumulators. They are less elegant for decumulators, and the gap shows up most painfully during inflation-regime drawdowns. We believe the next generation of QDIAs will incorporate a more explicit inflation-protection sleeve and a dedicated cash reserve in the retirement-proximate glidepath tail. Until plan sponsors and product designers close that gap, participants in the 2025 through 2035 vintage cohorts should, in our view, understand exactly what their TDF is doing and consider a small overlay.
