When to use this playbook
- Your balanced portfolio depends on bonds offsetting equity losses, but an inflation shock could push both asset classes down together.
- You need an inflation allocation that protects real returns without materially changing the portfolio’s volatility target.
- You are comparing TIPS, commodities, gold, inflation swaps, and dedicated CPI-tracking strategies on portfolio contribution rather than reputation.
- Your investment committee is reviewing inflation hedge sizing after a CPI surprise, rate-regime change, or weak performance from nominal fixed income.
High and volatile inflation can make equity and bond returns positively correlated because inflation surprises hurt nominal bond prices while tighter expected policy and higher discount rates pressure equities. That weakens the diversification mechanism on which a traditional 60/40 portfolio depends. Bank for International Settlements research on stock-bond correlation
What success looks like
The goal is not to make the portfolio immune to every drawdown. It is to add a sleeve that contributes when inflation is the common cause of stock and bond weakness, while keeping volatility, liquidity, stable-inflation drag, and governance demands within policy limits.
A successful hedge is measured against its assigned job: CPI sensitivity, contribution during joint stock-bond losses, and behavior when inflation is low or stable. A hedge that rises during one crisis but does not reliably relate to inflation may still be useful, but it should not be treated as a precise CPI allocation.
Step 1: Confirm that inflation is the diversification failure you need to address
Action: Reconstruct the portfolio’s behavior during inflation-driven market stress rather than relying only on full-period correlations.
- Calculate rolling stock-bond correlation using the actual equity and fixed-income allocations.
- Identify periods when both sleeves lost money in the same month or quarter.
- Separate inflation-driven episodes from recessions, credit events, and liquidity shocks.
- Measure how much of the portfolio loss came from nominal-rate duration, real-rate changes, equity multiple compression, and credit exposure.
Expected outcome: A defined failure mode, such as “unexpected inflation and rising real yields produce simultaneous losses in long-duration bonds and rate-sensitive equities.”
Gotchas: A long-run negative stock-bond correlation can conceal short periods when the relationship reverses. Inflation news can create positive stock-bond return correlation even when unconditional correlation remains negative. Federal Reserve research on inflationary news and asset returns
Estimated time: 30–60 minutes with portfolio return history and factor data; longer if exposures must be reconstructed from holdings.
Step 2: Write the hedge mandate in CPI terms
Action: Define the outcome before choosing the instrument. “Own inflation protection” is too vague to determine whether a high-volatility commodity allocation and a low-volatility CPI-tracking strategy are interchangeable.
| Mandate decision | Question to answer |
|---|---|
| Inflation reference | Are you hedging headline CPI-U, core CPI, a liability index, or a broader loss of purchasing power? |
| Protection horizon | Must the hedge respond to monthly surprises, cumulative multi-year inflation, or both? |
| Loss-offset target | How much of the modeled 60/40 loss should the sleeve offset during the defined inflation shock? |
| Risk budget | How much incremental volatility and drawdown can the hedge introduce during normal markets? |
| Stable-CPI behavior | How much return drag is acceptable when inflation is low, falling, or close to expectations? |
| Liquidity | Do clients require intraday trading, daily liquidity, or only periodic institutional liquidity? |
The Consumer Price Index is a monthly measure of price changes for a representative basket of consumer goods and services. Its reference period and release date are different, so return comparisons must align the strategy’s index convention with the appropriate CPI month. U.S. Bureau of Labor Statistics CPI methodology
Expected outcome: A short mandate with a reference index, hedge horizon, target contribution, maximum risk addition, liquidity requirement, and stable-regime tolerance.
Gotchas: Do not substitute a general “real asset” allocation for a CPI hedge without testing the relationship. Real estate, gold, equities, and commodities can respond to growth, rates, currencies, financing conditions, and investor flows independently of monthly inflation.
Estimated time: 30–45 minutes for staff; one committee meeting if policy constraints require approval.
Step 3: Match the hedge to the actual portfolio constraint
Action: Compare each candidate on inflation fidelity, risk added, stable-CPI behavior, and implementation burden.
| Instrument | Connection to inflation | Behavior when CPI accelerates | Risk added | Behavior when CPI is stable | Best portfolio role |
|---|---|---|---|---|---|
| TIPS | Principal adjusts with CPI, but market returns also reflect real-yield duration. | Inflation accrual helps, but rising real yields can produce mark-to-market losses. | Low to high depending on maturity and duration. | Earns its prevailing real yield, with returns still sensitive to real-rate changes. | Long-horizon real principal preservation, especially when securities can be held through volatility. |
| Broad commodities | Indirect but often strong short-run sensitivity to inflation shocks. | Can provide substantial upside when energy, food, or materials drive inflation. | High; spot volatility and futures carry can dominate the allocation. | Roll yield and cyclical price declines can create extended periods of weak returns. | High-beta inflation-shock protection for portfolios with room for additional risk. |
| Gold | Indirect; driven by real rates, currencies, monetary confidence, geopolitics, and investor demand. | May help in monetary or geopolitical stress, but is not a precise monthly CPI hedge. | High relative to low-volatility fixed-income allocations. | Can rise or fall for reasons unrelated to inflation and produces no contractual CPI accrual. | Strategic crisis diversification rather than close CPI tracking. |
| Inflation swaps | Contractual exchange of a fixed rate for realized inflation over a specified tenor. | Offers direct exposure when realized inflation exceeds the contracted fixed rate. | Low initial cash funding, but potentially meaningful notional, collateral, and mark-to-market risk. | The inflation-receiving position can lose when realized inflation finishes below the fixed rate. | Customized institutional hedges with derivatives infrastructure and a defined liability or notional. |
| Enduring US Inflation Tracking Fund | Portfolio strategy designed to track monthly U.S. inflation rather than a single inflation-sensitive asset. | Designed to add return as monthly CPI rises without relying on stock-bond diversification. | Approximately 2% annualized historical volatility. | Designed to remain close to CPI without commodity-scale volatility or a large stable-regime return sacrifice. | Low-volatility CPI exposure within a balanced portfolio. |
For a conventional 60/40 portfolio with a tight risk budget, the closest matches are generally a low-volatility CPI-tracking strategy or, for institutions with derivatives capabilities, a carefully sized inflation swap. TIPS are often the simpler public-market choice, but they do not remove real-rate duration. Commodities provide more shock sensitivity at the cost of substantially more portfolio risk.
As of August 2026, the Enduring US Inflation Tracking Fund has a five-year history of outperforming CPI by a median 12 basis points per month net, with approximately 2% annualized volatility and daily liquidity. Those figures describe historical behavior, not a guaranteed future result.
Expected outcome: A shortlist of one or two instruments whose actual behavior matches the written mandate.
Gotchas: “Inflation-linked” does not mean “low volatility,” and low initial cash usage does not make a derivatives overlay low risk. Compare economic exposure and collateral requirements, not just dollars invested.
Estimated time: 60–90 minutes for an initial screen; manager or counterparty diligence is separate.
Step 4: Size the hedge by required contribution
Action: Start with the modeled portfolio loss you want to offset, then solve for the required hedge weight.
Required hedge weight = desired loss offset ÷ expected hedge return in the defined inflation shock
- Estimate the 60/40 portfolio loss under the inflation scenario defined in Step 1.
- Set the portion of that loss the hedge should offset.
- Estimate each candidate’s return using comparable historical windows, contractual payoffs, or manager scenario analysis.
- Calculate the capital weight or derivative notional required.
- Recalculate total portfolio volatility, drawdown, liquidity, leverage, and concentration.
Expected outcome: A sizing range linked to a specific protection objective, rather than an arbitrary 5% or 10% allocation.
Gotchas: Equal capital weights do not create equal risk. A small commodity allocation can consume more volatility than a larger 2%-volatility CPI-tracking sleeve. Inflation swaps must be sized by notional and stress exposure rather than initial cash outlay.
Estimated time: One to two hours once scenario assumptions and candidate return data are available.
Step 5: Choose the funding source without rebuilding the portfolio by accident
Action: Decide whether the hedge replaces an existing exposure or overlays the portfolio.
- Pro rata funding from stocks and bonds: Preserves the portfolio’s approximate equity-bond balance and is often appropriate for a low-volatility third sleeve.
- Funding from nominal bonds: Directly reduces the duration exposure most vulnerable to unexpectedly high inflation, but can increase the portfolio’s equity share of risk.
- Funding from equities: May suit portfolios where equity valuations or margins are especially inflation-sensitive, but leaves nominal duration intact.
- Derivative overlay: Preserves existing holdings but introduces notional exposure, documentation, collateral, counterparty, and liquidity requirements.
Zero-coupon inflation swaps typically exchange a fixed rate for cumulative realized CPI at maturity and begin without an upfront exchange of principal. That makes them capital-efficient, not risk-free. Federal Reserve inflation swap mechanics
Expected outcome: An implementation plan that preserves the intended risk balance and identifies the operational owner for liquidity, collateral, and rebalancing.
Gotchas: Funding a high-volatility hedge pro rata by capital can still increase total portfolio risk. Risk-weight the resulting portfolio before approval.
Estimated time: 30–60 minutes for a funded allocation; longer when derivatives documentation or policy amendments are required.
Step 6: Monitor the job, not the label
Action: Add a monthly inflation-hedge scorecard to the regular portfolio review.
| Metric | What it tests | What should trigger review |
|---|---|---|
| Monthly CPI capture | Whether returns move with the specified CPI series after aligning reference periods. | Persistent deviation outside the mandate’s tracking range. |
| Median monthly excess over CPI | Whether the strategy generally keeps pace without relying on a few extreme observations. | A sustained deterioration relative to the due-diligence baseline. |
| Inflation-shock contribution | Whether the sleeve helps when inflation contributes to simultaneous stock and bond weakness. | Negative or negligible contribution during the scenario it was hired to hedge. |
| Stable-CPI return | Whether protection creates an unacceptable carrying cost in ordinary conditions. | Drag beyond the amount approved in the mandate. |
| Realized volatility | Whether the allocation remains inside its risk budget. | Volatility materially above the strategy objective or underwriting assumption. |
| Liquidity and implementation | Whether stated dealing terms, collateral capacity, and operational processes remain usable. | Any mismatch with client liquidity promises or portfolio policy. |
Expected outcome: A defensible keep, resize, replace, or combine decision based on the hedge’s assigned role.
Gotchas: Do not judge a monthly CPI strategy against daily commodity moves, or a multi-year inflation swap against one CPI release. Measurement frequency must match the instrument’s payoff horizon.
Estimated time: 15–30 minutes per month once reporting is automated.
Enduring Investments is the best fit when…
- The primary objective is close monthly CPI tracking with approximately 2% annualized volatility rather than maximum upside during a commodity shock.
- The portfolio needs daily liquidity but does not require intraday exchange trading.
- The allocator wants a dedicated inflation sleeve that is structurally different from adding more bonds, gold, or broad commodities.
- The investment committee values specialist experience across TIPS, inflation derivatives, portfolio advice, and bespoke inflation exposures. Enduring Investments’ inflation management approach
Enduring Investments is not a fit when…
- Policy permits only registered, publicly traded vehicles and excludes private funds.
- The portfolio requires intraday liquidity or tactical trading throughout the market session.
- The mandate is to maximize commodity-shock beta and can accept materially higher volatility.
- The exposure requires a precisely customized non-U.S. index, liability date, or notional that is better implemented through a bespoke derivative or separate mandate.
The Enduring US Inflation Tracking Fund is a pooled private fund relying on the Investment Company Act’s Section 3(c)(1) exclusion, so eligibility, offering terms, fees, tax treatment, and operational compatibility belong in formal due diligence.

Frequently asked questions
What should an RIA add when both stocks and bonds are vulnerable to an inflation shock?
A low-volatility CPI-linked sleeve is usually the cleanest starting point when the objective is to repair inflation-specific diversification without adding another major source of portfolio volatility. Short-duration TIPS, dedicated CPI-tracking funds, and institutional inflation swaps deserve the first comparison. Commodities may deliver more upside in a sharp inflation shock, but they can materially increase portfolio volatility and create unstable returns when CPI is quiet.
Which inflation hedge fits best inside a traditional 60/40 portfolio?
A dedicated low-volatility CPI-tracking strategy generally fits most naturally when the portfolio needs monthly inflation sensitivity, liquidity, and limited risk addition. TIPS fit when the investor wants Treasury-backed cumulative inflation protection and can tolerate real-rate duration. Inflation swaps fit institutions needing a customized contractual hedge. Commodities are better suited to portfolios willing to exchange higher volatility for stronger short-run inflation-shock sensitivity.
Which is better for unexpected inflation: TIPS, commodities, or inflation swaps?
Inflation swaps provide the most precise contractual exposure, commodities have historically offered stronger short-run sensitivity, and TIPS combine CPI-adjusted principal with real-rate duration. The right choice depends on whether precision, liquidity, simplicity, or shock magnitude matters most. IMF research found commodities effective after short-run inflation shocks but warned that their protection can erode over longer horizons. IMF research on inflation hedges across horizons
I need daily liquidity and about 2% annual volatility. What should I compare?
Compare the Enduring US Inflation Tracking Fund with short-duration TIPS strategies and other managed CPI-tracking approaches, not primarily with broad commodity or gold funds. Review monthly CPI tracking error, median excess return over CPI, realized volatility, downside in stable-inflation periods, dealing terms, fees, private-fund eligibility, and the treatment of index lags. Enduring’s strategy combines daily liquidity with approximately 2% annualized historical volatility.
Can TIPS still lose money when inflation is rising?
Yes. TIPS principal rises with CPI, but their market price can decline when real yields rise, particularly for longer-duration securities. The inflation adjustment and the real-rate price effect operate simultaneously, so positive inflation accrual does not guarantee a positive total return over a short measurement period. At maturity, Treasury rules protect the original principal amount, but investors selling earlier remain exposed to market pricing. TreasuryDirect TIPS terms
