BLDX vs IGF

BLDXCImpax Global Infrastructure ETF

IGFAiShares Global Infrastructure ETF

In short

BLDX An active swing at global infrastructure in a corner of the market run by cheap index trackers. BLDX's managers hand-pick companies building out sustainable infrastructure and the shift to a more sustainable global economy.

IGF About 80 developed-market infrastructure companies in one ticker, tracked against the S&P Global Infrastructure Index since 2007, for 0.37% a year (well under the category norm).

Stated mandate

BLDX The Fund seeks capital appreciation and income through an actively managed portfolio focused on companies contributing to sustainable infrastructure and the transition to a more sustainable global economy.

IGF The Fund seeks to track an index of developed-market equities focused on the infrastructure industry.

Why people hold it

• BLDX Actively managed, not index-bound. A manager decides which infrastructure names make the portfolio instead of inheriting whatever the benchmark happens to hold.
• Global mandate with a transition tilt: companies contributing to sustainable infrastructure and a more sustainable economy, a narrower lens than generic toll-road-and-pipeline baskets.
• Built for two jobs at once, capital appreciation and income, with distributions paid on an annual or semiannual schedule.

• IGF Costs 0.37% a year against a cohort median of 0.55%, so the toll on a long hold is smaller than most infrastructure funds charge.
• The one other fund on the same S&P Global Infrastructure Index, GII, charges 0.40%. Same benchmark, cheaper wrapper here.
• Trading since December 2007, now a multi-billion-dollar, actively traded fund that has tracked its index closely.
• Goes global where the biggest peers stay home: IFRA and PAVE are US-only, while this one spans developed markets worldwide.

Worth knowing

• BLDX 0.60% a year runs above the infrastructure cohort's typical fee and above index rivals like IGF (0.37%) and PAVE (0.47%). Active management is what the extra buys.
• A 2026 launch that is thinly traded and small by category standards, so spreads can run wider than on the group's household names.
• No public index rulebook to audit: what qualifies as sustainable infrastructure is the manager's call, and the fund sits in the lower half of its peer group today.

• IGF About 80 holdings in one industry. A concentrated basket, so a bad stretch for utilities or transport operators shows up fast.
• Distributions arrive once or twice a year, not monthly, and foreign holdings bring currency swings along with the dividends.
• Developed markets only. The fast-building infrastructure of emerging economies sits outside the mandate.
