10.4 Real Estate, Infrastructure, and Commodities

Real assets in portfolio context

Real assets are investments tied to physical or productive property: real estate, infrastructure, timberland, farmland, and commodities. They can offer exposure to inflation, income, scarcity, and economic activity, but they also carry operating risk, regulation, environmental risk, leverage, and illiquidity. The exam does not ask you to treat all real assets alike; an office building, a cell tower, a toll road, a pipeline, gold bullion, and wheat futures each have different cash-flow drivers. The shared skill is identifying what creates return and what creates risk.

Real estate

Real estate returns come from rental income, occupancy, rent growth, operating expenses, financing cost, capital expenditures, and terminal value. Direct ownership offers control and potential tax benefits but creates concentration, operating responsibility, appraisal uncertainty, and high transaction costs that can exceed 5-7% of value on a sale.

A REIT (real estate investment trust) provides liquid, publicly traded exposure. REITs improve access and diversification, but their market price moves with equity markets, interest rates, leverage expectations, and investor sentiment. A REIT is not the same as direct ownership of one building.

Net operating income (NOI) is central: it is property revenue less operating expenses, before financing costs and income taxes. The capitalization (cap) rate links income to value, where value = NOI / cap rate. A lower cap rate implies a higher value for a given NOI, all else equal, and cap rates tend to rise (values fall) when interest rates rise.

Infrastructure

Infrastructure assets deliver essential services: transportation, utilities, communication, energy, water, and social facilities such as hospitals or schools. They have long lives, high upfront capital costs, and strong barriers to entry. Cash flows may be regulated (an approved return on a rate base), contracted (a long-term power-purchase agreement), availability-based (paid for being ready to operate), or volume/usage-based (toll roads, ports).

The stage also matters: brownfield assets are existing and operating, offering steadier income, while greenfield assets are under development and carry construction and demand risk. Infrastructure can provide stable, inflation-linked income, but political, regulatory, construction, environmental, and demand risks remain.

Commodities

Commodity exposure can come from physical ownership, futures, commodity-linked equities, ETFs, or funds. Commodities generally produce no cash flow like bonds or rental property; returns depend on supply-and-demand shocks, inventory levels, geopolitics, weather, currency moves, and inflation expectations.

For futures-based exposure, total return has three parts: spot return (change in the underlying price), collateral return (interest earned on cash backing the futures), and roll yield (the gain or loss from rolling an expiring contract into a later one). The roll sign depends on the futures curve:

• Backwardation: later contracts are priced below near contracts, so rolling into cheaper later contracts produces a positive roll yield.
• Contango: later contracts are priced above near contracts, so rolling produces a negative roll yield.

Exam traps

Do not call every real asset an inflation hedge without qualification. Some assets pass inflation through directly; others face capped tariffs, fixed contracts, rising operating costs, or demand destruction. Inflation sensitivity depends on pricing power, contract terms, leverage, and replacement cost. And do not confuse commodity spot returns with futures returns: a commodity index can underperform a rising spot price when the curve is in contango and collateral return is low. Listed vehicles provide liquidity but may trade like public equities during market stress.

Why commodities have no convenience yield for the investor, and other nuances

The futures price is linked to the spot price through the cost of carry: storage costs and financing push the futures price up, while a convenience yield (the benefit of holding the physical commodity, such as keeping a refinery running) pushes it down. When convenience yield is high relative to storage and financing, the curve tends toward backwardation; when storage and financing dominate, the curve tends toward contango. A Level I candidate is not asked to compute these precisely but should connect the curve shape to the roll-yield sign.

Real estate adds two more testable mechanics. Leverage amplifies equity returns and losses on a property, so a small change in property value can swing equity returns dramatically once a mortgage is in place. And the loan-to-value ratio and debt-service coverage determine refinancing risk: a property bought at a low cap rate with high leverage can become distressed if rates rise and the asset must be refinanced at a higher cost.

For infrastructure, the key nuance is that regulated assets earn a set return on a rate base, so they behave more like long-duration bonds and are sensitive to interest-rate changes, whereas usage-based assets behave more like equities tied to economic activity. Tagging each real asset to its dominant risk factor, rates, demand, or commodity price, is what the exam rewards.
