DFSB vs GRNB

DFSBADimensional Global Sustainability Fixed Income ETF

GRNBAVanEck Green Bond ETF

In short

DFSB Dimensional's global investment-grade bond book, run through a carbon filter: issuers with heavy emissions intensity or fossil fuel reserves get cut or trimmed. Active, around 700 bonds, 0.23% net of a waiver through February 28, 2027.

GRNB Its peer group is stacked with total-bond-market giants. GRNB goes narrow instead: only dollar-denominated green bonds funding environmental projects, issued worldwide by governments, supranationals and companies. A 2017-vintage specialist at 0.20%.

Stated mandate

DFSB The ETF seeks to maximize total returns through income and capital appreciation from the debt securities in which it invests.

GRNB The fund seeks to track the S&P Green Bond U.S. Dollar Select Index before fees and expenses. The index covers U.S.-dollar-denominated green bonds financing environmentally friendly projects and issued globally by supranational, government, and corporate entities.

Why people hold it

• DFSB Costs 0.23%, net of a waiver through February 28, 2027, against 0.24% gross, and sits below the median fee among the 29 global bond funds we price.
• The screen reaches past corporates: supranationals and certain government agencies judged less sustainable also get excluded or underweighted.sec.gov
• No index to hug. Dimensional shifts duration and credit exposure as premiums move, and the prospectus says it intends to hedge foreign currency exposure.sec.govmutualfunds.com
• Holdings match the stated mandate closely: investment-grade debt of US and non-US corporate and government issuers, mortgage-backed bonds included.sec.gov

• GRNB The mandate is the point: bonds whose proceeds fund environmentally friendly projects, tracked to the S&P Green Bond U.S. Dollar Select Index instead of a generic aggregate benchmark.vaneck.com
• 0.20% a year runs below the typical fund in its category, and it sits in the top quartile of a large aggregate-bond peer group on how closely it tracks and what it holds.
• Global sourcing, dollar pricing: supranational, government and corporate issuers, roughly 500 bonds, all USD-denominated, so no currency translation layered on top.
• Distributions land monthly, and the fund has been running since 2017.

Worth knowing

• DFSB The screens mean this will not look like a plain global aggregate. Excluded energy-heavy issuers can push returns away from the broad market.sec.gov
• You pay for the filter and the active hand. BNDW covers global bonds for 0.05% with no sustainability screen.
• Moderately traded rather than a volume heavyweight, so spreads and order size are worth watching.

• GRNB Thinly traded next to core bond giants like BND, so spreads and order type matter more here.
• Green describes what the proceeds fund, not an issuer's whole business; the credit still sits with governments, supranationals and companies.
• The screen costs extra: plain aggregate rivals like BND and SPAB list expense ratios near 0.03%.
