The US Consumer Price Index hit 3.8% in April 2026 - the highest reading since May 2023. Behind the number: energy costs up 17.9% year-over-year, shelter inflation re-accelerating to 3.3%, and tariff pressures showing up across apparel, household goods, and transportation. Real wages fell 0.3% annually in the same report. The Iran war that began in late February disrupted oil supply through the Strait of Hormuz. Tariffs introduced in early 2025 continue to filter through supply chains. The Federal Reserve, which came into 2026 expecting to cut rates, is now fielding questions about whether it needs to raise them.
The question investors need to answer is not whether inflation is a problem. It clearly is. The question is which assets actually protect purchasing power in this environment, and which ones only appear to. This guide runs through each asset class - mechanically, historically, and with current data - so you can make that call with precision rather than intuition.
The Framework: Two Different Questions
Before running through asset classes, it helps to separate two questions that often get conflated.
Does this asset preserve purchasing power over decades? That is a long-run question about real returns. Most diversified equity portfolios answer yes, over long enough horizons.
Does this asset hold up when inflation spikes over the next 1-3 years? That is a shorter-run question about correlation with inflation regimes. The answers are quite different, and the confusion between the two is where most inflation-hedging mistakes come from.
Gold, for example, is a reasonable long-run purchasing power preserver - its real return over 50 years is roughly zero, meaning it tracks inflation across very long periods. But month-to-month, its correlation with CPI is essentially noise. An investor who bought gold expecting it to rise whenever the next CPI print came in hot has consistently been disappointed.
Commodities, by contrast, have a strong short-run correlation with inflation - partly because commodity prices are themselves a driver of headline CPI. They work well as short-term hedges but are volatile and cycle-dependent over longer periods.
Keeping that distinction in mind makes the asset-by-asset analysis considerably cleaner.
What Actually Works: Asset by Asset
TIPS - Treasury Inflation-Protected Securities
TIPS are the most mechanically precise inflation hedge available to US investors. The principal adjusts daily with the CPI, the fixed coupon is applied to the adjusted principal, and at maturity you receive the greater of the original or adjusted principal. There is no ambiguity about whether the hedge works - it is built into the structure.
The current numbers are worth knowing. The 10-year TIPS real yield is approximately 2.17%, following a recent auction that cleared at 2.169%. That means a 10-year TIPS purchased today locks in a return of CPI + 2.17% annually for a decade. With headline CPI running at 3.8%, the nominal equivalent is roughly 6% - meaningfully above most fixed-rate alternatives.
The 10-year TIPS breakeven rate sits at 2.45% and the 5-year breakeven at 2.59%, based on Fed data as of May 2026. These figures represent what the market expects average inflation to be over those periods. If actual inflation comes in above 2.59% over the next five years - which the current trajectory supports - TIPS buyers will outperform holders of equivalent nominal Treasuries.
A few practical considerations. Short-term TIPS yields turned briefly negative after the Iran war began in February, as investors rushed for inflation protection. That demand effect can compress the entry point. For investors who want TIPS exposure without managing individual bonds, iShares TIPS Bond ETF (TIP) and Vanguard Short-Term Inflation-Protected Securities ETF (VTIP) provide diversified access.
For non-US investors: TIPS are a US government instrument indexed to US CPI - not the inflation rate in your country of residence. Three Irish-domiciled UCITS equivalents provide access without US estate tax exposure: iShares USD TIPS UCITS ETF (ITPS, IE00B1FZSC47), Amundi US TIPS Government Inflation-Linked Bond UCITS ETF (LU1452600270), and SPDR Bloomberg US TIPS UCITS ETF (SYBY). All three track the same Bloomberg US Government Inflation-Linked Bond index.
I Bonds - Series I Savings Bonds
I Bonds are a US Treasury savings instrument that combines a fixed rate with a variable rate tied directly to CPI. The current composite rate is 4.26% for bonds purchased from May 1 through October 31, 2026, comprising a fixed component of 0.90% and a variable component of 3.34%. That variable component resets every six months in line with CPI.
At 4.26%, I Bonds are broadly competitive with top-tier high-yield savings accounts and one-year CDs, both currently offering around 4%. The difference is that the I Bond rate rises if inflation rises. If the November 2026 reset reflects the current trajectory, the rate will move higher. The fixed component of 0.90% is locked in for the life of the bond - a reasonable entry point relative to the current rate environment.
The significant constraints: purchases are limited to $10,000 per person per year through TreasuryDirect, plus an additional $5,000 through a tax refund. You cannot redeem within 12 months of purchase. Redemptions within five years forfeit the last three months of interest. And I Bonds are available only to US persons - US citizens, residents, and certain US entities.
For US investors with a one-to-five year horizon who want a simple, liquid, government-backed inflation hedge, I Bonds remain one of the cleaner options in the market. For non-US investors, they are not accessible.
UK Index-Linked Gilts
For UK investors and expats with GBP exposure, index-linked gilts (ILGs) are the sterling equivalent of TIPS. The UK was one of the earliest developed economies to issue inflation-indexed government bonds, and the market is deep and liquid.
The current picture as of late May 2026: the 10-year nominal gilt yields 4.86% - down from a peak of 5.07–5.10% on May 12, the highest level since July 2008. The 10-year index-linked gilt offers a real yield of 1.65% above RPI (as of May 12; not yet updated for late May), with RPI currently running at 4.1%. The implied breakeven rate sits at 3.42%.
That 1.65% real yield is the highest entry point in 16 years. For UK investors or expats managing GBP liabilities who want a government-backed real return over a decade, today’s ILG market offers a meaningful opportunity. The recent pullback in the nominal gilt from 5.07% to 4.86% has not been matched by an updated real yield figure - monitor gilt-edge.uk for the latest reading before executing.
One structural point worth knowing: UK index-linked gilts are indexed to RPI (Retail Price Index), not CPI. RPI has historically run 0.5–1% above CPI due to methodological differences. That indexation basis is an advantage in inflationary periods - but the UK government has confirmed a transition toward CPIH alignment from 2030, which will reduce the inflation uplift on existing long-dated linkers from that date. Investors in 20- or 30-year ILGs should factor this into their real return expectations.
Access for non-US investors: iShares £ Index-Linked Gilts UCITS ETF (INXG, IE00B1FZSD53) trades on the London Stock Exchange and provides broad GBP index-linked gilt exposure. Amundi UK Government Inflation-Linked Bond UCITS ETF (LU1407893301) is an alternative. Both are confirmed active as of May 2026.

German Inflation-Linked Bonds (Bundesanleihen)
For euro-area investors and expats with EUR liabilities, German inflation-linked federal bonds are the sovereign equivalent of TIPS within the eurozone. Both the principal and coupon are indexed to the eurozone HICP (Harmonised Index of Consumer Prices, excluding tobacco), calculated by Eurostat.
Four inflation-linked German federal bonds remain in issue, with a total outstanding volume of €47.05 billion. Individual bond real yields as of early May 2026 are not publicly available due to very thin trading volume - the German ILB market traded only €58 billion in 2024, falling to just 1% of total federal securities turnover. The best available proxy for EUR inflation-linked real yields is the ECB’s eurozone aggregate: as of February 10, 2026, the 10-year eurozone real yield stood at 0.74% and the 10-year eurozone breakeven at 2.06%.
| ISIN | Maturity | Duration (approx.) | Notes |
|---|---|---|---|
| DE0001030559 | Apr 2030 | ~4 years | Short-duration EUR inflation protection |
| DE0001030583 | Apr 2046 | ~19 years | Long-duration real return lock-in |

These real yields are considerably lower than the 1.65% available on UK index-linked gilts or the 2.17% on US TIPS - a reflection of the safe-haven premium in German sovereign debt. For EUR-based investors managing EUR liabilities, the trade-off between lower real return and currency-matched government guarantee may still be appropriate.
Two structural points to understand before investing. First, Germany stopped issuing new inflation-linked bonds in November 2023 and will not reopen existing series. The four current issues will trade until maturity, but the market will not grow, and secondary market liquidity is already thin. Second, the 10-year Bund nominal yield reached approximately 3.05–3.20% in May 2026 - its highest level since 2011 - implying market-priced eurozone inflation expectations of roughly 2.3–2.5% at the 10-year horizon, above the ECB’s 2% target.
Access for non-US investors: Direct bond purchase through IBKR or Saxo is the cleanest route for large allocations. For smaller allocations or broader eurozone inflation-linked exposure, Amundi Euro Government Inflation-Linked Bond UCITS ETF (LYQ7, LU1650491282, accumulating) and its distributing share class (LU1650491795) both trade on Xetra and are confirmed active as of May 2026. These funds hold a basket of eurozone inflation-linked sovereigns, not just German Bunds.

Gold
Gold’s inflation-hedging properties are more nuanced than most coverage suggests, and it is worth being precise.
Gold is a poor short-run CPI hedge. The month-to-month correlation between gold prices and CPI readings is close to zero. Buying gold the week before a CPI print expecting a price reaction is not a reliable strategy.
Gold is a reasonable long-run purchasing power preserver. Over 50-year horizons, gold’s real return is roughly flat - it maintains purchasing power across very long periods. Since the gold standard ended in 1971, CPI has risen approximately 650%, implying a dollar in 1971 tracking inflation would be worth about $7.50 today. Gold, priced at around $4,700 per ounce currently (down from its January 2026 all-time high of $5,589), has substantially outpaced that.
The variable that actually drives gold prices in the medium term is real yields, not inflation per se. Gold pays no yield, so its opportunity cost is the real return available on risk-free assets. When real yields fall, gold becomes more attractive. When real yields rise, gold faces headwind. This is why gold struggled in 2022 even as CPI hit 9% - the Fed’s rapid rate hikes pushed real yields sharply positive, which created a strong competing return.
Gold’s role in a portfolio for 2026 is most defensible as a hedge against monetary policy failure or systemic stress - scenarios where the normal relationship between inflation and real yields breaks down. Central bank gold buying, now averaging 585 tonnes per quarter globally according to J.P. Morgan data, provides structural support.
Access: For US investors, SPDR Gold Trust (GLD) and iShares Gold Trust (IAU) offer the simplest exposure. For non-US investors, iShares Physical Gold ETC (IGLN, IE00B4ND3602) is Irish-domiciled and avoids US estate tax exposure. WisdomTree Physical Gold (PHAU, JE00B1VS3770) is another widely-used alternative trading on the London Stock Exchange.
Commodities
Among all inflation-hedging asset classes, commodities have the most direct short-run relationship with CPI - largely because commodity prices are themselves an input to headline inflation. Energy, food, metals, and agricultural products move first; the CPI data follows.
The 2026 data makes the point clearly. The Bloomberg Commodity Index Total Return posted a gain of 29.65% year-to-date through April 30, 2026, driven by energy (oil up sharply post-Iran war), metals, and agricultural commodities. That is a substantial real return in an environment where CPI is running at 3.8%.
The historical record supports the short-run relationship. According to Hartford Funds research covering inflationary periods since 1973, energy stocks outperformed inflation in 74% of high-and-rising inflation periods, delivering an average annual real return of 12.9%. The mechanism is direct: energy company revenues are tied to energy prices, which are themselves a key driver of headline CPI.
The important caveat is that these returns are cyclical and driven by commodity price levels, not just inflation rates. Commodities can deliver strong nominal returns during inflationary shocks and give much of it back when the supply disruption resolves. An investor who held commodities through 2021–2022 and exited into 2023 experienced exactly that - strong gains followed by a sharp correction as supply chains normalized.
Access: For US investors, SPDR S&P Metals & Mining ETF (XME) and iShares S&P GSCI Commodity-Indexed Trust (GSG) provide diversified access. For non-US investors, iShares Bloomberg Roll Select Commodity Swap UCITS ETF (ROLL, IE00BZ1NCS44) is Irish-domiciled and avoids the US estate tax issue. Invesco Bloomberg Commodity UCITS ETF (CMOD, IE00BD6FTQ80) is another UCITS option with broad commodity exposure.
The practical role for commodities in a portfolio: a tactical overweight during inflationary spikes, not a permanent strategic allocation for most investors. A 5–10% position in a diversified portfolio provides meaningful inflation correlation without the cyclical risk dominating overall returns.
Infrastructure
Infrastructure is one of the cleanest structural inflation hedges available in public markets, and one of the least discussed.
The mechanism is direct: regulated utilities, toll roads, pipelines, ports, and data infrastructure typically have revenue contracts, regulatory frameworks, or concession agreements that explicitly index prices to inflation. When CPI rises, revenues rise. This is not a correlation argument - it is a contractual one.
Brookfield Infrastructure Partners (BIP/BIPC), the largest publicly traded pure infrastructure vehicle, reported Q1 2026 funds from operations of $709 million, a 10% increase year-over-year. The utilities segment specifically called out inflation indexation as the primary driver of base business growth - not volume growth or market exposure, but direct contractual pass-through of rising prices. The company targets long-term total returns of 12–15% annually.
At the broader asset class level, infrastructure equities have historically delivered equity-like returns with lower volatility and a built-in inflation linkage that most sectors cannot replicate.
Access: For US investors, iShares Global Infrastructure ETF (IGF) and SPDR S&P Global Infrastructure ETF (GII) provide broad exposure. For non-US investors, iShares Global Infrastructure UCITS ETF (INFR, IE00B1FZS467) is Irish-domiciled. Both IGF and INFR hold largely the same underlying assets; INFR is the appropriate vehicle for investors managing US estate tax exposure.
The risk to monitor: infrastructure companies typically carry significant debt to fund long-lived assets. Rising interest rates - which often accompany inflation - increase financing costs and can pressure valuations even as operating cash flows grow. For infrastructure as an inflation hedge to work cleanly, the inflation-linked revenue growth needs to exceed the increase in debt service costs. The current environment, where inflation is driven primarily by energy rather than broad monetary excess, generally supports that trade-off.
Equity REITs
Equity REITs - companies that own income-producing real estate - have outperformed inflation in 66% of historical high-and-rising inflation periods, delivering an average annual real return of 4.6%, according to Hartford Funds research covering periods since 1973. The mechanism is straightforward: rental income from commercial properties has historically kept pace with inflation, and the value of the underlying properties typically rises with the general price level.
The important distinction between equity REITs and mortgage REITs applies here. Mortgage REITs invest in real estate debt rather than properties themselves, and their fixed coupon payments lose real value as inflation rises - essentially the same problem as holding regular bonds. Equity REITs own the assets and benefit from rising rents; mortgage REITs do not.
The tension in 2026 is that rising interest rates weigh on REIT share prices even when the underlying business performs well. Cohen & Steers, which manages one of the largest dedicated REIT strategies, noted that REITs are relatively well positioned in periods of lower growth and macro uncertainty due to stable lease-based cash flows, but flagged that prolonged conflict increasing stagflationary pressures represents the primary downside risk.
Access: For US investors, Vanguard Real Estate ETF (VNQ) provides broad equity REIT exposure. For non-US investors, iShares Developed Markets Property Yield UCITS ETF (IWDP, IE00B1FZS350) is the Irish-domiciled equivalent. Infrastructure-adjacent REITs - data centers, cell towers, industrial logistics - have shown stronger inflation pass-through than traditional office or retail REITs in recent cycles, and both VNQ and IWDP have meaningful exposure to these sub-sectors.
What Does Not Work
The question of what fails as an inflation hedge is as important as what succeeds, and some of the most common holdings are the worst performers.
Long-duration nominal bonds lose purchasing power in real terms when inflation rises. A 30-year Treasury bond paying a fixed 4.5% coupon is generating a negative real return when CPI is at 3.8%. The loss is not nominal - the coupon keeps arriving - but each dollar of coupon buys less. Duration risk is amplified: a 1% rise in rates causes roughly 15–20% decline in the price of a 20-year bond.
Cash and money market funds preserve nominal value but lose ground against inflation when the yield on cash falls below the inflation rate. With money market yields around 4.3–4.5% and CPI at 3.8%, cash is roughly breaking even in real terms right now - which is better than in 2022, but leaves essentially no real return.
Long-duration growth stocks have a structural problem in inflationary environments: their value derives from earnings expected far in the future, and higher discount rates reduce the present value of those earnings. This is why high-multiple technology and growth stocks underperformed dramatically in 2022 even as energy and commodity stocks surged.
Nominal annuities and fixed-income insurance products lock in a nominal payment stream that inflates away over time. A $2,000 monthly annuity payment that sounded comfortable at purchase looks significantly worse after a decade of 3–4% annual inflation.
Building the Portfolio
No single asset class is the complete answer. The most effective inflation-resistant portfolios combine assets that hedge different aspects of the problem.

| I Bonds | TreasuryDirect | CPI-linked, government-backed, tax-deferred | $10K/yr max per person |
| Equity REITs | VNQ | Long-run real return, rental pass-through | 5–10% of equity |
| Commodities | GSG / XME | Short-run CPI correlation, tactical | 5–10%, rebalance actively |
| Infrastructure | IGF / BIP | Contractual inflation linkage, income | 5–10% of equity |
| Energy equities | XLE / XOP | Highest historical real return in inflation | Within equity allocation |

Two concrete examples:
Non-US investor, 5-year horizon, moderate risk tolerance: The primary concern is a near-term inflation spike eroding the real value of cash and short-duration bonds. The appropriate portfolio emphasizes short-duration inflation-linked bonds (ITPS or direct index-linked gilts in your home currency), a tactical commodity allocation (ROLL at 8–10%), and cash in a high-yield account that at least partially tracks short rates. Infrastructure and REITs are secondary here - their inflation linkage is real but operates over longer horizons.
Non-US investor, 10-year horizon, growth-oriented: The primary concern is long-run purchasing power erosion. Infrastructure (INFR at 8–10%) and equity REITs (IWDP at 5–8%) both offer contractual or structural inflation linkage with equity-like return potential. A smaller TIPS UCITS allocation (ITPS at 5–10% of fixed income) provides a direct CPI anchor. Gold (IGLN at 3–5%) adds systemic risk protection. Commodities are a smaller tactical allocation (3–5%), rebalanced actively rather than held as a permanent position.
The key construction principle applies to both: size inflation-hedging assets relative to your actual inflation exposure - your future spending currency, your income stability, and whether your liabilities are fixed in nominal or real terms. An investor whose income adjusts automatically with prices has less inflation risk than someone on a fixed salary or a fixed pension. Adjust accordingly.
The Breakeven Test
For TIPS and inflation-linked bonds specifically, the breakeven rate is the single most useful number to know before investing.
The 5-year TIPS breakeven is currently 2.59% and the 10-year is 2.45%. These represent the average annual inflation rate that makes TIPS and nominal Treasuries produce equivalent returns. If you believe actual inflation will exceed 2.45% annually over the next 10 years - which is consistent with current CPI of 3.8%, a sustained Iran war premium, ongoing tariff effects, and sticky services inflation - then TIPS offers better value than nominal Treasuries of the same maturity.
If you believe inflation will quickly revert to 2% or below within a year or two, nominal Treasuries are the better trade. Markets are currently pricing the middle ground - elevated inflation near-term, but mean-reverting over a decade. Whether that pricing is right depends on factors that are genuinely uncertain: the duration of the Middle East conflict, the trajectory of US-China trade policy, and whether the Fed acts preemptively or waits.
The portfolio implication is not to bet the whole position on one outcome. Holding both nominal and inflation-linked bonds across the duration spectrum is a reasonable way to avoid the breakeven bet entirely while maintaining fixed income exposure.
The Bottom Line
Three things are true simultaneously in 2026. Inflation is running well above target. The assets best positioned to protect against it are clearly identifiable - TIPS, commodities, infrastructure, energy equities. And the right allocation depends entirely on your time horizon, your currency of actual spending, and whether you are hedging short-run CPI shocks or long-run purchasing power erosion.
For US investors, the toolkit is straightforward: TIPS at a real yield of 2.17%, I Bonds at 4.26% for the first $10,000, and tactical commodity and infrastructure exposure on top. For non-US investors, the same exposures are available through UCITS vehicles without US estate tax complications - but the starting real yields are lower outside the US, particularly in EUR.
The investors who will fare best are not the ones who made the most dramatic portfolio pivot. They are the ones who understood what they owned, why it hedged what it hedged, and sized their positions to match their actual exposure - not their anxiety about the next CPI print.
Inflation eventually comes down. Real-return discipline, built into a portfolio before that happens, tends to outlast the cycle.
