• The abrdn Physical Gold Shares ETF combines competitive pricing with ESG considerations
• Trading liquidity and share pricing structures vary across funds and can impact smaller investors

Gold’s 2025 Performance and Investment Context

As of mid-December 2025, precious metals have delivered impressive returns, with spot prices advancing 62% year-to-date. Should this momentum persist through year-end, it would represent the strongest annual performance in nearly five decades, and only the fourth-best calendar year on record dating back over a century. The last comparable performance occurred in 1979, when gold appreciated 133%.

Interestingly, gold’s gains in 2025 haven’t primarily resulted from traditional defensive positioning. The broader equity market, as measured by the S&P 500, has also performed strongly with gains exceeding 14%. Meanwhile, inflation remains moderately elevated at around 3% annualized—elevated relative to Federal Reserve targets but not accelerating significantly.

This dynamic reveals an important insight about gold’s true role in portfolios. Rather than serving purely as an inflation hedge or defensive safe haven, gold functions most effectively as a volatility diversifier. Historically, the correlation between U.S. equities and precious metals hovers near zero over extended periods. This characteristic makes gold a valuable component for reducing overall portfolio risk through genuine diversification benefits.

The Cost Advantage Strategy: Why Fee Structure Matters

When comparing physical gold ETFs, an important principle emerges: since these funds essentially replicate the same underlying asset—bullion stored in secure vaults—the differentiation comes down to cost management.

Two metrics deserve your attention when evaluating funds:

Expense Ratios: The annual fees charged by fund managers, typically expressed as a percentage of assets. Over 20 or 30 years, seemingly small differences compound significantly. A 0.30% fee difference on a $10,000 investment could mean thousands in forgone returns.

Trading Spreads: The difference between bid and ask prices when you buy or sell shares. Funds with substantial assets under management typically exhibit tighter spreads, meaning lower transaction costs for individual investors.

By prioritizing lower fees, you maximize the actual returns reaching your pocket—a strategy that proves particularly effective over multi-year investment horizons.

The Mini Share Revolution: Lower Cost, Greater Accessibility

SPDR Gold MiniShares Trust (GLDM) - The Fee Leader

The SPDR Gold Trust (GLD) holds distinction as the largest and most widely recognized gold ETF product, commanding approximately $60 billion in assets. However, this prominence comes with a trade-off: its 0.40% annual expense ratio ranks among the highest in the category.

Recognizing this pricing opportunity, State Street launched a more economical sibling: SPDR Gold MiniShares Trust (GLDM). This fund charges just 0.10% annually—a 75% fee reduction compared to its larger counterpart. With over $25 billion in assets under management, GLDM maintains substantial liquidity and attracts razor-thin trading spreads comparable to premium funds.

The “mini shares” structure also provides a practical advantage for retail investors managing modest portfolio sizes. Because share prices trade significantly lower than GLD, investors requiring smaller capital allocations can still establish meaningful positions without price barriers.

iShares Gold Trust Micro (IAUM) - The Cost Winner

A parallel dynamic exists within the iShares product lineup. The iShares Gold Trust (IAU) represents the second-largest gold ETF vehicle globally but charges 0.25% annually—still substantially higher than emerging alternatives.

In response, BlackRock introduced iShares Gold Trust Micro (IAUM), which captures the fee war trophy at just 0.09% per year. Despite managing approximately $6 billion in assets—considerably smaller than flagship competitors—IAUM maintains adequate liquidity and tradability for most investors.

The lower share price structure similarly benefits capital-constrained investors seeking gold exposure without requiring large initial commitments. For those prioritizing pure cost efficiency, IAUM represents the mathematically optimal choice in the current landscape.

Alternative Consideration: ESG-Aligned Gold Investing

abrdn Physical Gold Shares ETF (SGOL)

The abrdn Physical Gold Shares ETF (SGOL) presents a slightly different value proposition by integrating environmental, social, and governance (ESG) considerations into its holdings strategy.

At 0.17% annually, SGOL’s fee falls between the ultra-low-cost micro funds and traditional offerings. The distinguishing factor: all bullion held post-2012 has undergone refinement aligned with the London Bullion Market Association’s Responsible Gold Guidance. This framework requires refiners to document environmental respect, combat money laundering, prevent terrorist financing, and protect human rights throughout supply chains.

For investors where ESG alignment influences portfolio decisions, SGOL merits consideration despite its slightly elevated fee structure. The additional 0.07-0.08% annual cost represents a reasonable premium for governance-aligned sourcing.

The Bottom Line: Fee Optimization Strategy

Physical gold ETFs fundamentally deliver similar exposure to the underlying commodity. Beyond minimal structural variations, the primary lever for outperformance involves minimizing unnecessary costs.

Investors implementing a disciplined approach should evaluate their priorities: If pure cost minimization drives your decision, IAUM’s 0.09% expense ratio commands attention. If you require maximum liquidity and scale, GLDM offers compelling value at 0.10%. Should ESG considerations matter to your investment philosophy, SGOL’s 0.17% remains reasonable relative to its differentiated approach.

Regardless of selection, committing to lower-cost structures versus traditional flagships (GLD at 0.40% and IAU at 0.25%) can preserve meaningful wealth over decades of holding, allowing your precious metals allocation to function efficiently within a diversified portfolio framework.
