Introduction to Multi-Asset Infrastructure Investing

The FTSE Multi-Asset Core Infrastructure Index Series represents a transformative step in how infrastructure investments are approached in modern financial markets. Traditionally, infrastructure investing has been segmented into equity or fixed income strategies, forcing investors to choose between growth-oriented assets and income-generating securities. However, this index series bridges that divide by combining both asset classes into a unified framework, offering a more balanced and comprehensive investment solution.

Developed by FTSE Russell, the index is structured to capture the performance of infrastructure assets globally. It spans both developed and emerging markets, providing investors with exposure to a wide array of opportunities across different economic environments. By integrating equity and debt instruments, the index reflects the true capital structure of infrastructure businesses, where both shareholders and bondholders play critical roles.

At its core, the index focuses on three essential infrastructure sectors: transportation, energy, and telecommunications. These sectors are fundamental to economic functioning, ensuring connectivity, power supply, and mobility. The inclusion of these sectors ensures that the index remains anchored in assets that deliver essential services, making it inherently resilient and long-term in nature.

Another key aspect of this index is its multi-currency exposure. Infrastructure assets are globally distributed, and their financing often occurs in different currencies. By incorporating multiple currencies, the index enhances diversification and allows investors to benefit from global macroeconomic trends.

 

The Strategic Case for Combining Equity and Debt in Infrastructure

The case for multi-asset infrastructure investing is rooted in diversification and risk optimization. Infrastructure equities and bonds exhibit different return characteristics, and their combination can lead to improved portfolio outcomes.

Equities typically provide capital appreciation and dividend growth. Infrastructure companies often operate under regulated frameworks or long-term contracts, which allow them to generate predictable cash flows and distribute consistent dividends. These dividends can also grow over time, especially in inflationary environments where pricing power increases.

In contrast, infrastructure bonds offer stable and contractual income through coupon payments. They tend to be less volatile than equities and can provide a cushion during market downturns. While they are exposed to interest rate and credit risks, their income-generating nature makes them attractive for conservative investors.

When combined, these two asset classes complement each other. During periods of economic expansion, equities drive returns through price appreciation. During downturns, bonds help preserve capital and provide income stability. This interplay results in improved risk-adjusted returns, making multi-asset infrastructure investing a compelling strategy.

Additionally, diversification across the capital structure enhances resilience. Bonds are senior to equities, meaning they have priority in receiving payments. This structural difference ensures that even if equity performance weakens, bondholders may still receive stable returns, reducing overall portfolio risk.

 

FTSE Russell’s Framework for Identifying Core Infrastructure

One of the distinguishing features of the FTSE Multi-Asset Core Infrastructure Index Series is its rigorous methodology for identifying genuine infrastructure assets. Rather than relying solely on sector classification, FTSE Russell employs a two-step approach that combines industry classification with revenue analysis.

The first step involves identifying companies operating in infrastructure-related sectors. However, not all companies within these sectors qualify as core infrastructure providers. Therefore, the second step applies a revenue threshold, requiring that a significant portion of a company’s revenue—typically at least 65 percent—must come from core infrastructure activities.

This approach ensures that only companies with substantial infrastructure exposure are included in the index. It eliminates entities that may operate in adjacent industries but do not derive the majority of their income from infrastructure services.

The framework also extends to fixed income securities. Bond issuers must demonstrate that their operations align with core infrastructure activities. This consistency across asset classes ensures that both equity and debt components of the index represent the same underlying infrastructure universe.

 

Index Construction and Methodology

The FTSE Multi-Asset Core Infrastructure Index Series is constructed by combining two established index families. The equity component is derived from the FTSE Infrastructure Index Series, while the fixed income component comes from the FTSE Fixed Income Core Infrastructure Index Series.

Within each component, securities are weighted based on market value. For equities, this means market capitalization weighting, where larger companies receive higher weights. For bonds, weighting is based on the outstanding value of the securities.

The index offers multiple fixed-weight variants, allowing investors to choose allocations that align with their objectives. These include:

  • 80 percent equity and 20 percent fixed income for growth-focused investors
  • 60 percent equity and 40 percent fixed income for balanced portfolios
  • 50 percent equity and 50 percent fixed income for equal exposure
  • 30 percent equity and 70 percent fixed income for income-focused strategies

Rebalancing occurs on a monthly basis, ensuring that the target allocations are maintained. This disciplined approach prevents drift and enforces a systematic buy-low, sell-high mechanism, which can enhance long-term returns.

 

Equity Component: Growth and Income Potential

The equity portion of the index captures listed infrastructure companies across global markets. These companies often exhibit strong fundamentals, including stable cash flows, high dividend yields, and defensive characteristics.

Infrastructure equities are known for their income-generating potential. Many companies in this sector distribute a significant portion of their earnings as dividends, resulting in yields that often exceed broader market averages. Additionally, these dividends tend to grow over time, particularly in sectors with inflation-linked revenue models.

Geographically, the equity component is diversified across developed and emerging markets. While developed markets dominate due to their mature infrastructure systems, emerging markets provide growth opportunities as they invest in new infrastructure projects.

Sector-wise, the equity component is spread across transportation, energy, and telecommunications, ensuring balanced exposure and reducing concentration risk.

 

Fixed Income Component: Stability and Income Generation

The fixed income segment of the index includes bonds issued by infrastructure companies and quasi-government entities. These securities provide steady income through coupon payments and contribute to overall portfolio stability.

The bond universe spans both investment-grade and high-yield securities, offering a range of risk-return profiles. Investment-grade bonds provide safety and lower risk, while high-yield bonds offer higher returns with increased credit risk.

Another important feature is multi-currency exposure. Bonds denominated in major currencies such as USD, EUR, GBP, JPY, AUD, and CAD provide additional diversification and reflect the global nature of infrastructure financing.

The duration of these bonds typically falls within intermediate to long-term ranges, aligning with the long-lived nature of infrastructure assets.

 

Diversification Across Sectors and Regions

One of the strongest advantages of this index is its diversification. By spreading investments across multiple sectors and geographies, it reduces exposure to any single risk factor.

Sector diversification ensures that the portfolio is not overly reliant on one area. For example, transportation may be influenced by trade cycles, while energy responds to commodity prices and policy changes. Telecommunications, on the other hand, benefits from technological advancements and increasing data demand.

Geographic diversification further enhances resilience. Developed markets provide stability and liquidity, while emerging markets offer higher growth potential. This combination creates a balanced global exposure.

Currency diversification also plays a role, as it allows investors to benefit from fluctuations in exchange rates while spreading risk across multiple economies.

 

Applications in Investment Portfolios

The FTSE Multi-Asset Core Infrastructure Index Series can be used in various ways within investment portfolios. It serves as a core allocation for infrastructure exposure, suitable for both institutional and individual investors.

Exchange-traded funds and index-linked products tracking the index provide easy access and liquidity. Institutional investors can use the index as a benchmark for evaluating active managers or as a building block in strategic asset allocation.

The index is also suitable for income-focused portfolios due to its combination of dividend-paying equities and coupon-generating bonds. Additionally, it can act as an inflation hedge, as infrastructure revenues often adjust with inflation.

 

Risk Management Benefits

Multi-asset infrastructure investing offers several risk management advantages. The combination of equities and bonds reduces overall volatility compared to equity-only portfolios.

The correlation between asset classes is not perfect, which means that losses in one component may be offset by gains or stability in the other. This leads to smoother return profiles and better downside protection.

Rebalancing further enhances risk management by maintaining target allocations and preventing excessive exposure to any single asset class.

Interest rate and inflation risks are also better managed within a multi-asset framework, as different components respond differently to economic changes.

 

ESG and Sustainability Considerations

Sustainability is becoming increasingly important in infrastructure investing. Many infrastructure assets play a crucial role in addressing environmental and social challenges.

The index includes exposure to renewable energy, energy-efficient systems, and sustainable transportation networks. Additionally, the inclusion of green bonds allows investors to support environmentally beneficial projects.

Infrastructure investments are closely aligned with global sustainability goals, as they contribute to economic development, energy transition, and improved living standards.

 

Future Outlook for Multi-Asset Infrastructure

The future of infrastructure investing is closely tied to global economic and technological trends. As economies continue to grow and evolve, the demand for infrastructure will increase.

Digital infrastructure, such as data centers and broadband networks, is emerging as a significant growth area. Similarly, the transition to renewable energy is creating new investment opportunities.

Emerging markets will continue to play a key role, as they invest heavily in infrastructure development to support economic growth.

The FTSE Multi-Asset Core Infrastructure Index Series is well-positioned to adapt to these changes, providing investors with exposure to both traditional and emerging infrastructure assets.
