Global political tensions are running high, and elevated interest rates have been a source of uncertainty for financial markets. Meanwhile, our Global Macro & Asset Allocation team believes that inflation will remain higher for longer and be more persistent. The team has noted that bonds are becoming less effective in their traditional role as economic shock absorbers as they move more in sync with stocks, even as inflation cools (Exhibit 1).

So, where can investors look for relatively steady investments amid economic volatility? As discussed in A New Foundation for Global Wealth, historical data show that private infrastructure investments have displayed less volatility than most other asset classes, while also producing attractive returns. The combination of those two factors has yielded compelling portfolio benefits relative to most other asset classes over the last 10 years (Exhibit 2).

In fact, reallocating just 10% of the equity portion of a traditional 60/40 portfolio to private infrastructure investments over the past 10 years would have resulted in lower volatility and higher risk-adjusted returns, without sacrificing overall excess returns (Exhibit 3). There is no guarantee that this trend will hold over the next 10 years; however, we think the very nature of infrastructure investments support their role in a portfolio as a volatility dampener.

Why Does Infrastructure Act as an Economic Shock Absorber?
We think there are two main reasons that infrastructure tends to reduce volatility in a portfolio.
1. Critical Assets with Stable Demand: Infrastructure assets—such as power generation, water distribution, data centers, or fiber-to-the-home networks—offer essential services that are the bedrock of an economy and society. Demand for these services typically remains relatively stable, regardless of broader economic conditions.
Moreover, the substantial startup costs to develop renewable energy generation projects, mobile communications infrastructure, or waste management capacity create high barriers to entry for potential competitors. These barriers lead to stable market structures over time, which make the cash flow profiles of infrastructure assets more stable.
2. Predictable Cash Flows: Private infrastructure investments are typically tied to physical assets with stable long-term cash flows. Revenues are often based on long-term contracts, some of which span decades and often include protections against inflation through CPI-linked escalators.
The resilience of infrastructure, stemming from the essential nature of infrastructure assets and high visibility into cash flows, was on full display in 2022, when interest rates climbed sharply and introduced new volatility across financial markets (Exhibit 4).

Private Infrastructure in Practice
To understand infrastructure’s shock-absorber capabilities, consider a few practical examples – some with infrastructure-like characteristics, and some without. While these were chosen specifically to illustrate the durability of infrastructure business models, they highlight the key attributes that underpin our risk-based approach to infrastructure.
In our view, the digital revolution is a long-term mega-theme that will play out well beyond the next decade. Consumers, businesses, governments, and all kinds of organizations will generate more digital data, underpinning continued growth in demand for data storage and processing. The buildout of data centers necessary to support this incredible growth will likely require hundreds of billions of dollars of capital investment. These investments are typically backed by long-term fixed revenue contracts with strong, investment-grade customers. Even in a severe economic downturn, we would not expect existing data centers supporting cloud computing customers to experience cash flow volatility given the nature of these contracts.
Another consistent global trend has been the transition to a low-carbon economy and the subsequent shift to renewable energy. Renewable energy businesses with long-term contracts often have a cushion against economic downturns in that long-term power purchase agreements with utilities and large-scale corporate customers tend to have fixed prices.
How do the infrastructure business models described above differ from other business models across the rest of the economy? Some media businesses are closely linked to the digitization trend, whether they provide streaming music or other kinds of content, that also encompasses data centers. However, many media businesses rely on revenue from two sources: subscriptions and advertising. Neither comes with long-term contracts. Subscribers can cancel easily, and advertising buys tend to occur on a short-term basis, with meaningful sensitivity to broad economic conditions and cycles. Media businesses may grow fast, but they also tend to attract heavy competition (given asset light business models and inherently lower entry barriers), and preferred formats, technologies, and providers may change quickly.
What sets infrastructure apart as a cushion against volatility are its ties to crucial, physical assets with stable end-market demand and highly predictable cash flows. At a time of great economic and geopolitical change, we think it is important to keep in mind that infrastructure historically has experienced less volatility than many other asset classes, even during economic shocks like 2022, while also producing attractive returns.
