It tracks a broad global infrastructure index, covering 17 infrastructure subsectors including telecom, energy utilities, midstream energy, transportation, waste and water utilities, and social infrastructure (hospitals, prisons, postal services).

It is well-suited for medium- to long-term investors looking to complement a U.S.-concentrated portfolio with global infrastructure exposure.

The ETF was launched in 2013 by Northern Trust Asset Management (FlexShares) and follows a passive (index-tracking) management approach.

It uses a representative sampling method to include companies worldwide that generate more than half of their revenue from infrastructure-related businesses. It spans a wide range of sectors such as telecom, energy, transportation, utilities, and social infrastructure, while applying caps to each supersector weight to mitigate concentration risk.

• Broad infrastructure definition covering 17 subsectors
• Geographic diversification across North America, Europe, Asia, and the Pacific

Assets under management (AUM) stand at $3.1B, with a total expense ratio of 0.47% annually.

The expense ratio is somewhat higher than that of comparable products such as IGF and FNDF, but it offers broader infrastructure exposure and greater geographic diversification.

Global infrastructure assets tend to be sensitive to interest rate cycles, and during rate-cutting periods, bond-proxy infrastructure companies such as utilities and transportation typically show relative recovery. The energy infrastructure subsector is affected by commodity price movements.

Long-term demand for infrastructure assets aligns with structural investment themes such as grid modernization, digital infrastructure expansion, and the renewable energy transition, drawing steady interest from institutional investors. It is also worth considering for investors seeking geographic diversification.

A broad infrastructure definition and global diversification are key strengths, while a relatively higher expense ratio and currency exposure are factors to watch.

Alternative ETFs and Related Products

IGF in the table is an iShares product in the same global infrastructure category, with some differences in expense level and index composition, while GUNR offers combined natural resources and infrastructure exposure. FNDF and GSIE are developed-market global diversification ETFs that include sectors beyond infrastructure. For investors who want infrastructure-focused exposure weighted toward U.S.-listed infrastructure names, comparable sector ETFs can be evaluated separately, and individual names such as WMB and ENB are worth considering for those seeking energy infrastructure concentration.

Points to review before investing in NFRA. Although it is a diversified global infrastructure product, the expense ratio, multi-currency exposure, and interest rate sensitivity should be carefully examined prior to purchase.

During rate-hiking cycles, bond-proxy infrastructure companies such as utilities may show relative weakness, and the large non-USD allocation means currency moves can affect returns. Regulatory changes in individual countries or sectors can also impact infrastructure company profitability.

The product is well-structured for investors seeking broad-based diversification across global infrastructure assets. If cost is the priority, IGF may be more attractive, while if geographic and sector diversification is the priority, NFRA's broader coverage is a key differentiator.
