As fixed income indexing solutions continue to evolve and innovate, one particular area of focus has been fixed maturity indices. Fixed maturity indices have existed in the U.S. for over 10 years, where adoption and growth continue to be strong. However, the market in Europe is newer, with fixed maturity constructs taking shape only over the last 18 months. While the European market remains in its early stages, adoption has accelerated, with total assets in Fixed Maturity ETFs exceeding USD 7 billion¹ since the first launch in 2023.

S&P DJI is excited to announce the launch of two new fixed maturity indices:

1. The iBoxx EUR Liquid High Yield 2027 3-Year Rolling
   • High Yield: This is the first fixed maturity index focusing on European high yield credit in the marketplace, offering a measurement of one of the higher yielding areas of European fixed income, in a fixed maturity construct.
   • Liquidity: This index draws from the well-established iBoxx EUR Liquid High Yield Index family, with selection criteria that focus more on liquidity of the bonds than its broader benchmark.
   • Rolling Maturity: This fixed maturity index has an innovative feature that is also new to the market in that it continues to roll into a subsequent three-year index, as opposed to expiring the way traditional fixed maturity indices do.
2. The iBoxx Sovereigns Italy & Spain Fixed Maturity 2029 Index: Has unique exposure within sovereigns, combining two countries that have historically had higher yields relative to the broader European sovereign benchmark.

As fixed maturity solutions expand across Europe, we take a closer look at the construction and utilization of fixed maturity indices, and how these two new indices offer innovation in construction and exposure.

What is a Fixed Maturity Index? How Does it Differ from a Broad Fixed Income Index?

A fixed maturity index measures bonds that expire within the same maturity year, often mentioned in the name of the index. If the final year of the fixed maturity index is 2030, the index would typically include bonds that mature in 2030. During the final year of the index, 2030, maturing bond proceeds would be invested into money market instruments. By the end of the year, the index would have converted to an index of money market instruments and would then typically expire. The "maturing" nature of a fixed maturity index is a key feature that differentiates it from a broad fixed income index, which typically remain in perpetuity.

Why is it Interesting That a Fixed Income Index "Matures"? How Are Fixed Maturity Indices Used?

The index maturing creates a similar profile to that of a maturing bond. As such, market participants could use fixed income indices in a similar way they use individual bonds with known expiration dates. This can be useful for managing duration and cash flows, or for building bond ladders with a series of maturing years. However, unlike individual bonds, bond indices may provide diversification benefits in that they represent a collection of bonds and may minimize transaction costs as individual bonds may be difficult to access.

How Is the iBoxx EUR Liquid High Yield 2027 3-Year Rolling Different? How Is It the Same?

The iBoxx EUR Liquid High Yield 2027 3-Year Rolling includes bonds with expirations from the same maturity year, from Oct. 1, 2026, to Sept. 30, 2027. This allows for the index to be used in the same manner as any fixed maturity index, whether to manage duration or cash flow needs. Throughout the final months of the maturity year of the index, bond proceeds are moved into an iBoxx EUR T-Bill Index.

After the final year, rather than expiring, the iBoxx EUR Liquid High Yield 2027 3-Year Rolling rolls into another three-year maturity index, putting weight back into high yield bonds with a three-year fixed maturity, extending the index to Sept. 30, 2030. The index continues to roll in three-year increments.

The rolling nature of this index is a unique feature in the fixed maturity market, providing the ability to roll into the next three-year maturity index, without having to experience the expiration of the index or having to reinvest proceeds.

The "Liquid" in the iBoxx EUR Liquid High Yield 2027 3-Year Rolling

The iBoxx EUR Liquid High Yield 2027 3-Year Rolling not only brings a EUR high yield credit option to the market but also does so in a liquidity enhanced way. Drawing upon the well-established iBoxx EUR Liquid High Yield index series, this index deploys the same criteria and methodology in measuring the liquid subset of the broad EUR high yield bond market. The index rules have been designed to offer a broad market coverage with an emphasis on liquidity to be suitable for OTC and exchange-traded derivatives, as well as ETFs. Higher minimum notional amounts and longer time to maturities are some requirements for the index constituents that aim to enhance liquidity in the index. This fixed maturity index takes a one-year maturity slice of the broader liquid EUR high yield index.

How Is the iBoxx Sovereigns Italy & Spain Fixed Maturity 2029 Index Unique versus the Rest of the Market?

The iBoxx Sovereigns Italy & Spain Fixed Maturity 2029 Index draws from the broader iBoxx EUR index series and includes sovereign debt issued by Spain and Italy with an expiration between Oct. 1, 2028, and Sept. 30, 2029. There is currently no other fixed maturity index that has this combination of sovereign countries. Historically, these two issuers have represented the higher-yielding end of the European sovereign debt spectrum. Both issuers generated higher returns among other Eurozone issuers in 2024.

We expect to see continued expansion in fixed maturity indexing solutions across Europe and other geographies, and S&P DJI is excited to be bringing these two innovative indices to market, offering investors greater insight into fixed income.

The S&P Composite 1500^® serves as a benchmark for the U.S. equity market, aggregating the performance of large caps, mid caps and small caps. While the S&P 500^® has global relevance, there is a universe beyond the S&P 500 that market participants sometimes overlook. The mid- and small-cap segments, as measured by the S&P MidCap 400^® and S&P SmallCap 600^®, offer distinct views in terms of exposure, sensitivity, diversification and return drivers.

Compared to The 500™, the S&P 400^® and S&P 600^® indices have different sector weights. As of Jan. 31, 2025, they were primarily underweight in Information Technology and Communication Services, while having greater weight in Industrials, Financials, Real Estate and Materials. Although weights vary across the size spectrum, the mid- and small-cap segments had higher weight in domestically focused sectors.

Additionally, the mid- and small-cap segments tend to be more diversified than their large-cap counterpart, which could be relevant for market participants looking to diversify away from large names. Using the adjusted HHI¹ to measure concentration, Exhibit 2 shows that the S&P 400 and S&P 600 were less concentrated than The 500.

Moving down the size spectrum presents both opportunities and challenges, resulting in different risk/return profiles. As shown in Exhibit 3, the S&P 400 and S&P 600 outperformed the S&P 500 over various periods but, not surprisingly, exhibited more volatility.

The S&P Composite 1500 is constructed with an earnings screen that requires consistent profitability for its new constituents. Therefore, in addition to the size tilt, the indices also have a positive tilt toward quality. Moreover, the S&P 400 and S&P 600 also tend to have a significant tilt toward value.

Considering indexing beyond large caps, Exhibit 5 presents data from our SPIVA Scorecards in the mid- and small-cap segments, demonstrating that active managers have found it challenging to outperform the S&P 400 and S&P 600. In fact, the percentage of underperforming funds increased to over 90% for longer time periods.

The S&P 500 is a staple in the U.S. equity market, but the S&P 400 and S&P 600 may offer interesting and distinct characteristics: diversification from mega-cap companies, tilts toward more domestically focused sectors and a reflection of high-growth prospect companies. In addition to these drivers, the indices have historically shown quality and value tilts. Furthermore, most active managers underperformed the indices over different time periods, providing evidence that a low cost, index-based approach can offer outperformance in the mid- and small-cap segments.

¹The Herfindahl-Hirschman Index (HHI) is a widely used metric for measuring concentration, determined as the sum of the squared percentage weights of the index constituents. The adjusted HHI is calculated by dividing the index HHI by the HHI of an equally weighted portfolio with the same number of stocks.

The energy transition represents a crucial market force with the potential to revolutionize our world. Over the two decades from Jan. 31, 2005, to Jan. 31, 2025, the S&P 500^® demonstrated a significant decarbonization, evidenced by a 73.9% decrease in its weighted average carbon intensity, as illustrated in Exhibit 1.¹ This material decrease highlights a shift in dynamics among The 500™'s constituents.

Central to this decarbonization is the growing adoption of renewable energy sources alongside a reduction in the use of fossil fuels. By utilizing S&P Global Trucost's Environmental data suite, we analyzed the energy consumption of S&P 500 constituents based on energy source, tracking changes in this energy mix over the past decade.¹ The findings of this analysis are summarized in Exhibit 2, which outlines the significant shifts in energy consumption patterns observed in recent years. Over the past decade, the role of renewables—consisting of hydroelectric, biomass and other renewables components—in the S&P 500's energy mix has more than doubled, jumping from 95.7k GWh to 200.6k GWh.

In contrast to the growth in renewables, the consumption of fossil fuel-based energy—consisting of coal, petroleum and natural gas—has declined by 8.8% within The 500, with petroleum usage nearly reduced to a quarter of its previous level, dropping from 16.5k GWh to 4.4k GWh (see Exhibit 2). This transition toward cleaner energy may be indicative of a market that is adapting to new economic conditions and embracing innovation.

In summary, the energy transition appears to be affecting S&P 500 constituents, and this serves as an indicator of how decarbonization is reshaping market dynamics. The insights derived from observing the The 500 during this transformative phase underscore the path the world is on as the energy landscape continues to evolve. For those interested in further examining the carbon metrics and fossil fuel reserves associated with S&P DJI's indices, additional details can be found in the Sustainability Index Dashboard.

Over the last 10 years, sustainable investing has become increasingly prevalent, and concerns surrounding the risk of greenwashing have increased. To assist S&P DJI's customers with new European Securities and Markets Authority (ESMA) fund naming guidelines, S&P DJI announced the renaming of the S&P 500^® ESG Index to the S&P 500 Scored & Screened Index. Please note that the regulatory guidance under the ESMA guidelines on fund names using ESG or sustainability-related terms does not apply directly to S&P DJI.¹

S&P 500 Scored & Screened Index: Same Methodology, Different Name

The S&P 500 Scored & Screened Index's objective remains the same: to track securities that meet specific sustainability criteria while reflecting the S&P 500's industry group weights.

The name change does not alter the methodology; the criteria for selecting and excluding constituents remain unchanged, ensuring consistency as a benchmark.

• The index applies various eligibility criteria, such as UNGC screens, S&P MSA Screens and S&P Business Activity Screens before using S&P Global ESG Scores to select and exclude constituents. The index aims to reflect 75% of the market cap within each industry group, focusing on the top-ranking eligible index constituents by S&P Global ESG Score to maintain sector neutrality.

The S&P 500 Scored & Screened Index has continued² to achieve an enhanced ESG score against the S&P 500 with an absolute 5.05% increase in aggregate (see Exhibit 2).

The S&P 500 Scored & Screened Index has maintained similar sector weights as the S&P 500,³ posting only a 6.44% sector-active share as of Feb. 10, 2025 (see Exhibit 3).

While performance is not the objective of the index, the S&P 500 Scored & Screened Index has outperformed the S&P 500 over the mid and long term, and not at the expense of an increased risk profile, as seen in Exhibit 4. Moreover, the S&P 500 Scored & Screened Index has maintained comparable performance to the S&P 500 thanks to its similar industry group weights, with an average annualized tracking error of 1.36%, demonstrating a relatively low deviation.

Ecosystem

The ecosystem linked to the S&P 500 Scored & Screened Index remains intact,⁴ supporting a variety of financial products such as ETFs, ETDs, mutual funds, insurance products and structured products. Key offerings include E-mini S&P 500 ESG Index Futures⁵ from CME and options contracts from Cboe.⁶ Despite the name change, the ecosystem's integrity and functionality continue to benefit investors and financial institutions.

Conclusion

The transition from the S&P 500 ESG Index to the S&P 500 Scored & Screened Index represents a significant step to accommodate index users in line with the ESMA guidelines on the use of ESG and sustainability-related terms in fund names while preserving the index's core principles. The index methodology remains the same, ensuring its reliability as an underlying benchmark for a vast ecosystem.

In a previous blog, we delved into the S&P Global Sustainable1 Climate Action Framework, a powerful tool designed to gauge companies' readiness for the low-carbon transition across three key pillars: Climate Governance and Strategy, Physical Risk Adaptation Strategy, and Climate Risk Mitigation and Alignment.

In this blog, we introduce the recently launched S&P World Climate Resilience Tilted Index, which presents an innovative approach to incorporate climate-related factors within an index. The index incorporates elements of the S&P Global Sustainable1 Climate Action Framework, carbon intensity and climate solution revenue exposure indicators, aiming to increase the weight or tilt toward companies that are relatively more climate resilient, carbon efficient and have higher exposure to green revenues. It was designed to complement S&P DJI's family of indices that integrate climate-related data by providing an index solution that factors in forward-looking climate transition considerations alongside climate risk and opportunity aspects, while remaining broadly diversified.

Introducing the S&P World Climate Resilience Tilted Index

The S&P World Climate Resilience Tilted Index is a broad-based index that aims to be industry group- and region-neutral relative to its underlying index, the S&P World Index.^[1]

The index does not seek to exclude specific sectors that are traditionally removed or underweighted from indices that focus on climate-related factors, such as Energy and Utilities. The index does, however, apply a few, common safeguarding exclusions (see Exhibit 1). Instead, the index aims to retain strong representation of sectors that have carbon-intensive companies that are nevertheless thought to be crucial to help adjust to a lower GHG emissions economy.

The index then tilts eligible companies' weights within each tilting group^[2] based on four tilting factors, as shown in Exhibit 2. These include backward-looking climate metrics, such as Carbon Intensity^[3]; strategy-related forward-looking elements, such as two pillars of the S&P Global Sustainable1 Climate Action Framework—namely the Climate Governance and Strategy and Physical Risk Adaptation Strategy; and finally, a component that reflects climate transition opportunities, as measured by the revenue exposure to Climate Impact Solutions.

By design, the index shows low active sector weights relative to the underlying S&P World Index. Traditionally underweighted sectors like Energy and Utilities have been preserved at similar benchmark sector weights, as the tilting is applied within the region-industry-group tilting groups, minimizing unintended sectoral biases. In other words, companies are under/overweighted only relative to their tilting group peers, resulting in a weighting scheme that is more comparable to the underlying index (see Exhibit 3).

The low sector active weights compared to the underlying index are also reflected in the reduced observed levels of tracking error historically, which were below 100 bps for all tested time periods (see Exhibit 4). In terms of performance, the return differential between the S&P World Climate Resilience Tilted Index and the S&P World Index was reduced (see Exhibit 5).

Based on back-tested historical data, the index achieved improvement across all tilting factors that are controlled for in the methodology, such as lower index-level weighted-average carbon intensity (WACI), lower exposure to physical risk and higher revenue exposure to companies providing solutions for climate impact (see Exhibit 6). Additionally, we see higher exposure to Transition Strategic companies and lower exposure to Transition Limited companies, which, while not controlled for explicitly, are a beneficial byproduct from the specific data inputs used in the index methodology.

The tangible impacts from climate change present a deeply complex global challenge. For investors seeking a tool to help integrate and measure climate-related considerations while maintaining broad sector diversification and leveraging forward-looking climate transition readiness signals, the S&P World Climate Resilience Tilted Index may provide an effective solution.

^[2] Tilting groups are defined as region-industry groups.

^[3] Please note that the index does not target a specified weighted-average carbon intensity improvement relative to the parent index.
