Real Assets: Income, Inflation and Risk
Real assets include property, infrastructure, land and commodity exposures. Their returns come from different sources: operating income, usage fees, resource prices or futures positions. Evaluate each cash-flow mechanism before assuming inflation protection.
The key decisions, at a glance
| Concept | What to do | Watch for |
|---|---|---|
| Real estate | Rent less operating costs supports property income. | Gross rent is not net operating income. |
| Infrastructure | Contracts, regulation and utilization determine receipts. | A long concession does not guarantee stable demand. |
| Natural resources | Prices, production costs and depletion affect value. | An increase in commodity prices may coincide with higher costs. |
| Commodity futures | Separate spot-price movement, roll effects and collateral income. | A futures strategy need not match the spot commodity return. |
1. Real estate
Rent less operating costs supports property income.
Watch for: Gross rent is not net operating income.
2. Infrastructure
Contracts, regulation and utilization determine receipts.
Watch for: A long concession does not guarantee stable demand.
3. Natural resources
Prices, production costs and depletion affect value.
Watch for: An increase in commodity prices may coincide with higher costs.
4. Commodity futures
Separate spot-price movement, roll effects and collateral income.
Watch for: A futures strategy need not match the spot commodity return.
Original worked case
Higher rents do not guarantee higher income
Given: A property earns $1.0m in annual rent with $0.4m of operating costs. In a stress case rent rises 5% while operating costs rise 15%. Ignore financing, tax and capital expenditures.
01 Base income
$1.0m - $0.4m = $0.60m NOI.
02 Stress income
$1.05m - $0.46m = $0.59m NOI.
03 Compare
NOI falls $0.01m, or 1.67%, despite higher rent.
Answer and interpretation
Inflation pass-through depends on both revenue and cost behavior. The lease terms and expense burden matter more than the real-asset label.
$m NOI · scale 0 to 0.63
| Scenario | Value |
|---|---|
| Base | 0.6 |
| Costs +15% | 0.59 |
| Both +5% | 0.63 |
Illustrative comparison, not historical returns. All cases use the same starting property.
Change one assumption
If rent and operating costs both rise 5%, NOI rises to $0.63m. Changing cost pass-through changes the result.

Understand the method
Part 1
Property returns start with occupancy and operating cash flow
Rental property converts space and location into contractual income. Potential rent is reduced by vacancy and collection losses, then recurring operating costs are deducted to obtain net operating income under the stated convention. Financing expenses belong to the capital structure, so deducting interest inside NOI and then valuing the property before debt would mix asset and equity analysis.
A direct-capitalization model divides stabilized NOI by a capitalization rate. It is a shortcut that embeds expectations about growth, risk and required return. A building undergoing lease-up or a major refurbishment may need explicit cash-flow forecasts instead. Also distinguish routine operating expenses from capital expenditure: an apparently healthy NOI can coexist with substantial cash requirements for a roof, tenant improvements or environmental work.
Part 2
Infrastructure cash flows depend on contracts and demand
A toll road, regulated network and contracted power facility need different models. User-paid revenue depends on demand and permitted prices. Availability-style payments depend on meeting service requirements. Regulation or contracts can reduce some revenue uncertainty while introducing counterparty, renegotiation and performance risk. Long asset lives do not guarantee stable cash distributions.
Development-stage projects also face completion, cost-overrun and financing risks before operations begin. An operating asset has observable use and maintenance history, but reinvestment and political exposure remain. In an inflation scenario, ask whether revenues can actually reset, how quickly they reset and whether wages, energy and debt costs rise first. A broad claim that infrastructure automatically hedges inflation is too strong.
Part 3
Land and resources combine biological, physical and price risks
Farmland can earn lease income or operating profit from crops, with exposure to yields, weather, water access, input costs and commodity prices. Timberland adds a biological growth component and, within constraints, some flexibility over harvest timing. Mineral assets depend on economically recoverable reserves and the cost and timing of extraction. Appraised land value is only one part of the return mechanism.
The ability to delay a harvest is useful only if the biological asset remains healthy and the investor can fund carrying costs. Likewise, a rising commodity price does not rescue every resource project: higher extraction costs, declining grade or required environmental expenditure can absorb the benefit. Identify the production volume, realized price and cost assumptions separately before attributing an expected return to inflation.
Part 4
A futures position is different from owning the physical commodity
A futures-based commodity strategy gains or loses as contract prices change and may also earn interest on collateral. Maintaining exposure requires moving from an expiring contract to a later one. The shape of the futures curve therefore matters. Contango describes later contracts priced above nearby ones; backwardation describes the reverse. These labels describe the curve, not a guaranteed forecast of future spot prices.
Do not record the entire price gap at the moment of a roll as an immediate trading loss. The investor changes contract exposure and contract quantity, with subsequent convergence and price movements determining returns. A simplified convergence example can isolate one effect, but a real total-return calculation must include the dates, collateral return, execution costs and chosen contract methodology.
Different real assets require different operating drivers
Rental property
- Cash-flow driver
- Occupied rent less operating costs
- Stress to test
- Vacancy plus refinancing at higher rates
Infrastructure
- Cash-flow driver
- Usage or contracted service payments
- Stress to test
- Demand shortfall or counterparty failure
Farmland or timber
- Cash-flow driver
- Yield, harvest timing and realized prices
- Stress to test
- Weather loss plus input inflation
Commodity futures
- Cash-flow driver
- Contract repricing and collateral return
- Stress to test
- Curve change and adverse convergence
More worked practice
Original teaching cases. Use the stated assumptions; these are not official exam questions or marking keys.
A commodity rises while a contract loses value
Given: A futures contract is bought at 105. At expiry, spot and the contract settle at 103. Initial spot was 100. Ignore collateral interest and costs; use one unit.
- 1The physical spot price rose from 100 to 103, a 3% change.
- 2The purchased futures contract lost 103 - 105 = 2 per unit.
- 3The initial futures premium converged away by expiry in this specified path.
Interpretation: Positive spot performance did not imply a positive futures gain. This is an illustrative contract path, not a forecast or a claim that every contango period produces a loss.
Check your understanding
Answer first, then open the explanation. These checks are original practice and do not generate an exam score.
1. Can interest expense be subtracted before using an unlevered property cap rate?
Not in the standard NOI convention used here. First value the property cash flow before financing, then account for debt to reach equity value.
2. Why might an inflation-linked revenue contract still produce lower cash flow?
Indexation may lag while operating and financing costs rise immediately. Contract caps and required capital spending can also limit the benefit.
3. Does a real asset always mean a physical asset held directly?
No. Investors may obtain exposure through securities, funds or derivatives. Analyse both the underlying economics and the access vehicle.
Common questions
Are real assets always an inflation hedge?
No. The effect depends on repricing rights, demand, expenses, financing and valuation rates. A label cannot establish a reliable hedge.
Is NOI the cash paid to equity investors?
No. NOI is before financing and generally before capital expenditures and tax. Equity cash flow requires further adjustments.
