Investors’ search for diversification and inflation protection has put a spotlight on infrastructure, made brighter by massive public investment programs, accelerating power demand, and an increasingly digitalized economy.

KEY TAKEAWAYS

  • A generational wave of capital investment opportunity
    An estimated nearly $100 trillion in necessary infrastructure spending in the next 15 years will drive opportunities amid governments’ limited financial means to satisfy all the demand.
  • An asset class with compelling investment attributes
    Listed infrastructure has delivered returns competitive with broad equities, but with attractive downside capture and lower volatility.
  • A diverse universe supported by structural growth trends
    Infrastructure companies are poised to benefit from distinct long-term investment themes, foremost increasing power demand, digital transformation of economies, and deglobalization.

A growing asset class with a compelling track record

The need for and provision of critical, essential services can create potential return-generating investment opportunities—and the necessity for infrastructure investment is substantial and global. In developed markets, critical upgrades are urgently required to address deteriorating service quality, from dangerous lead levels in city water supplies to derailments of freight and passenger trains.

Meanwhile, emerging economies frequently need critical investment to support demographically fueled economic growth, expand urban capacity and meet the demand for higher standards of living.

Globally, governments have either proposed or enacted massive infrastructure investment programs to address these needs, while also seeking to drive a sustainable economic recovery and reduce carbon emissions.

But governments around the world are not positioned to satisfy all the demand. All told, an estimated $15 trillion funding shortfall by 2040 is creating investment opportunities, ranging from privatization of government assets to existing companies expanding their asset bases (Exhibit 1).

While historic public infrastructure spending programs have raised the public profile of infrastructure as an asset class, we see several fundamental factors driving demand for listed infrastructure allocations, including:

  • Appetite for infrastructure’s attractive historical investment attributes, including the potential for strong total returns, reduced volatility and inflation protection
  • Access to critical forces driving economic change, including power demand and decarbonization, digital transformation of economies, and deglobalization
  • Appreciation that listed infrastructure may be an effective complement to private infrastructure investments, offering diversified exposure with access to assets and industries that may be less available to private investors

A historically attractive return profile

Listed infrastructure has little overlap with broad stocks, accounting for just 4% of the MSCI World Index, and provides access to subsectors and investment themes that are typically under-represented in equity market allocations.

Performance data over the past 30 years (Exhibit 2) indicates that listed infrastructure offers the potential for:

  • Competitive performance relative to global equities, with three-year rolling total returns averaging 7.2%
  • Resilience in down markets, with infrastructure historically experiencing 60–70% of the market’s decline, on average, in periods when global equities retreat
  • Lower volatility, driven by the relatively predictable cash flows of infrastructure businesses

Listed infrastructure has delivered returns competitive with broad equities, but with attractive downside capture, low equity beta and lower volatility.

Beneficial inflation characteristics

Infrastructure has historically delivered strong relative returns during periods of higher-than-expected inflation, compared with modest or negative relative performance for stocks and bonds (Exhibit 3). This positive sensitivity has resulted from inflation-linked pricing mechanisms in many infrastructure revenue models, which provide for contractual adjustments to user fees. These adjustments may be based on fixed increases approximating inflation or on variable increases linked to consumer or producer price changes (see inset table).

Providing essential services

The historically compelling return profile is the result of fundamental characteristics of infrastructure businesses:

Long-lived real assetsInfrastructure companies own physical assets with useful lives typically greater than 20 years.
High barriers to entryCompetition is often limited by strict zoning restrictions, large capital requirements and, in some cases, exclusivity rights, which make it difficult or prohibitive for new entrants.
Stable cash flowsInfrastructure businesses typically operate in regulated industries, potentially enhancing the predictability of cash flows and lowering financial risk.
Inelastic demandThe essential nature of infrastructure means demand tends to be relatively resilient in economic downturns (though this varies by sector).

Through listed infrastructure companies, investors can gain access to a globally diversified portfolio of infrastructure assets with a market capitalization of roughly US$5.8 trillion, spread across the Americas, Europe and Asia Pacific. The investment universe contains a broad range of subsectors spanning four main categories:

UtilitiesCommunicationsTransportationEnergy
ElectricData centersAirportsMidstream
GasSatellitesMarine ports
RenewablesTowersRailways
WaterToll roads

Active management opportunities

Each infrastructure subsector has distinct performance drivers, resulting in a wide dispersion in returns in a given period. In the past 30 years, the difference between the best and worst subsector calendar-year returns was generally higher than 30%, as exemplified in Exhibit 4. Differences in returns are typically even greater at the security level. This wide range in outcomes offers active listed infrastructure investment managers an opportunity to take subsector-level positions with high conviction—which may enhance the performance of portfolios.

A diverse universe supported by structural growth trends

We believe this asset class is positioned to benefit from three distinct long-term investment themes:

  1. Power demand and decarbonization driving a global “more of everything” energy approach
  2. Digital transformation of economies affecting nearly every industry
  3. Deglobalization and evolving global supply chains

We believe that population growth, data processing led by artificial intelligence (AI), precision manufacturing, and other factors in the electrification of the economy will drive power demand growth not seen in a generation. This phenomenon is creating substantial opportunities for listed infrastructure companies. With a “more of everything” approach having become more accepted, we see opportunities related to both fossil fuel and renewable power generation.

While power demand in the United States has been largely flat for nearly two decades, this trend is now reversing. We expect overall power demand to grow about 4% per year, on average, through 2030 (Exhibit 5). Some utilities are expected to see demand growth well above 5%.

We believe that many investors fail to appreciate that there will be both winners and losers in a world of higher power demand. We believe there will be opportunities for utilities, midstream energy (due to demand for natural gas) and nuclear power. However, there are regulatory nuances to navigate, as well as a need to separate hype from substance. We believe active managers that are acutely focused on infrastructure markets are well positioned to identify true beneficiaries.

Digital transformation of economies

Virtually every industry is moving to build out digital platforms, and the expansion of artificial intelligence (AI), in its early innings, appears poised to be the next key long-term driver of this trend, on top of 5G demand. AI automation and broader enterprise and consumer adoption will likely require greater investment in wireless networks.

The rapid expansion in data usage in the late-4G environment, coupled with the expected urgent demands of the approaching 5G era, will likely require massive investments to expand communications infrastructure capacity over the next decade. Industry estimates show potential for a roughly 2.5x increase in global mobile data traffic by 2030, with 5G networks expected to carry more than half of all traffic (Exhibit 6). This growth will likely support demand for cell tower, satellite, and data center services assets for years to come.

We are witnessing an ongoing evolution of global supply chains as a result of diverse geopolitical dynamics, deglobalization, and nearshoring. The infrastructure universe is well represented by companies with assets that help move people and goods around the globe—most specifically, railways, marine ports, airports and toll roads operators. They form a critical part of the global supply chain, facilitating the flow of products ranging from semiconductor chips and medical supplies to everyday household items.

Logistics operators stand to benefit over time from factors such as operational advancements, e-commerce trends, and the strategic onshoring of industrial activity. Freight railway owners, for example, appear poised to continue to see improvements in operations and higher capital returns, potentially increasing company free-cash-flow generation over the next several years.

Infrastructure companies that focus on people and goods logistics account for as much as 30% of leading infrastructure stock indexes.

A liquid complement to private infrastructure

Listed infrastructure is a compelling way to invest in a rapidly growing sector of the global economy, combining attributes of private infrastructure investments with additional potential benefits.

Liquidity icon

Private investment lock-up periods can exceed 10 years, while investors in listed infrastructure vehicles can adjust allocations at their discretion. Further, listed infrastructure securities trade on public markets in real time. This allows managers to potentially capitalize on dislocations that may occur in listed values, as well as to efficiently manage allocation changes.

Diversification icon

Private funds often invest in just a handful of assets concentrated within a few geographies and/or subsectors. According to Preqin, the average private fund, for instance, holds around eight investments, versus more than 60 in a listed infrastructure strategy. Listed investments offer greater diversification—even at the security level. For example, listed infrastructure companies often own dozens of assets, which may be spread across multiple geographies.

Corporate governance icon

Listed companies are subject to oversight by regulatory agencies, which require strict standards of corporate governance, financial reporting and information disclosure. In the U.S., the Securities and Exchange Commission requires quarterly statements as well as detailed supplementals. The adoption of best practices in corporate governance can align managers’ interests with those of shareholders.

Insight search icon

The number and variety of infrastructure assets available for private investment are fairly low at any point in time. Moreover, some subsectors (notably airports, railroads and digital infrastructure) aren’t typically available to private buyers. A listed infrastructure portfolio can offer exposure across a wide range of sectors, geographic regions and market capitalizations.

A potentially attractive entry point for allocations

As awareness of listed infrastructure’s potential benefits has grown, so too have allocations from both institutional and retail investors. Further, while infrastructure has long appealed to those seeking diversification and stable income, the asset class’s positive inflation characteristics are now providing an additional incentive amid rising tariffs and deglobalization trends.

Given rising inflation risks, uncertain return prospects in fixed income, and growing concentration in equity markets, we believe this is an attractive opportunity to allocate to global listed infrastructure.

A differentiated performance profile
  • History of strong relative performance in inflationary periods
  • Potential to improve long-term risk-adjusted returns and reduce downside risk during equity market declines
  • Potential for 3–4% dividend yield and 4–6% long-term cash flow growth(1)
Compelling investment themes
  • Historical underinvestment in infrastructure leading to critical deterioration in service quality, requiring both public and private capital investment to modernize assets
  • Digital transformation affecting nearly every industry, driving long-term growth for cell towers and data centers
  • Utilities and renewables developers positioned to benefit from growing support and competitive costs for clean energy investments
  • Transportation sectors such as freight rails and marine ports essential to solving the world’s evolving supply chain needs
An attractive complement to private infrastructure
  • Ease of implementation at a time of record dry powder in private infrastructure funds
  • Opportunities for global diversification within an infrastructure allocation
  • Benefits of liquidity and the oversight of public markets
