Key Takeaways

  • For most investors: IAU (iShares Gold Trust) offers the best balance of low cost (0.25% expense ratio) and strong liquidity
  • For active traders: GLD (SPDR Gold Shares) has the tightest bid-ask spreads and deepest liquidity — every dollar of unnecessary spread matters at high frequency
  • For lowest possible cost: BAR (GraniteShares Gold Trust) at 0.17% expense ratio is the cheapest option among established gold ETFs
  • For offshore vault preference: SGOL (Aberdeen Standard Physical Gold) stores gold in Switzerland — ideal for investors seeking geographic diversification of custody
  • IRA investors: All four qualify for IRAs, but verify with your custodian as treatment can vary
  • Key tax fact: Physical gold ETFs are taxed as collectibles (28% max federal rate) regardless of holding period — unlike equity ETFs at 20% long-term rate

Gold ETFs have fundamentally changed how investors access the gold market. Before their introduction, getting exposure to gold required buying physical bars or coins (with premiums, storage costs, and liquidity challenges), or using futures (with rollover costs and leverage complexities). ETFs provide direct physical gold exposure in a brokerage account, with instant liquidity, no storage hassle, and low annual costs.

But not all gold ETFs are identical. Expense ratios range from 0.17% to 0.40%. Vault locations vary from London to New York to Zurich. AUM ranges from $600 million to $80 billion. Choosing the wrong ETF could cost you 0.23% per year — $230 on every $100,000 invested — for no additional benefit. This guide eliminates the confusion.

Individual ETF Profiles

GLD
SPDR Gold Shares — State Street Global Advisors
Expense Ratio0.40%
AUM$80.2 billion
Daily Volume (avg)8.2M shares
CustodianHSBC London
Gold per Share0.09312 oz
Best for: Active traders and institutions requiring maximum liquidity. GLD is the most recognized gold ETF globally and trades with penny-wide bid-ask spreads at massive scale. The 0.40% expense ratio is the highest of the four, but the deep liquidity means large trades ($1M+) execute without meaningful market impact. Long-term buy-and-hold investors will pay more here than necessary.
IAU
iShares Gold Trust — BlackRock
Expense Ratio0.25%
AUM$34.1 billion
Daily Volume (avg)11.4M shares
CustodianJPMorgan London
Gold per Share0.01012 oz
Best for: Most long-term investors. IAU's 0.25% expense ratio saves 0.15% annually over GLD with only marginally reduced liquidity. At $50/share, it's also more accessible for smaller investors and easier to buy in fractional amounts. The lower share price also means dollar-cost averaging is more practical. BlackRock's backing provides institutional confidence.
SGOL
Aberdeen Standard Physical Gold Shares ETF
Expense Ratio0.17%
AUM$3.8 billion
Daily Volume (avg)0.9M shares
CustodianJPMorgan Zurich, Switzerland
Gold per Share0.09721 oz
Best for: Investors who want geographic custody diversification. Switzerland has centuries of financial neutrality, strong property rights laws, and is outside both US and EU jurisdiction. SGOL's 0.17% expense ratio also makes it cheaper than GLD and IAU. Lower AUM means slightly wider bid-ask spreads — avoid large market orders; use limit orders.
BAR
GraniteShares Gold Trust
Expense Ratio0.17%
AUM$1.2 billion
Daily Volume (avg)0.5M shares
CustodianICBC Standard Bank, London
Gold per Share0.01014 oz
Best for: Cost-conscious long-term holders with smaller position sizes. At 0.17%, BAR ties SGOL as the cheapest option. However, its $1.2B AUM is significantly smaller than competitors — fine for individual investors but creates some liquidity concern for very large positions. ICBC Standard Bank as custodian is less recognized than HSBC or JPMorgan.

True Cost of Ownership: 10-Year Analysis

Expense ratios compound over time. Here is the total cost impact on a $100,000 investment over 10 years, assuming gold prices are constant (this isolates the cost difference only):

ETF Annual Fee on $100K 5-Year Cost 10-Year Cost vs. IAU over 10 Years
GLD $400 $2,000 $4,000 +$1,500 more expensive
IAU $250 $1,250 $2,500
SGOL $170 $850 $1,700 -$800 cheaper
BAR $170 $850 $1,700 -$800 cheaper

The cost difference is meaningful but not enormous for most individual investors. On a $10,000 position, the 10-year difference between GLD and BAR is $230 — real money, but not the primary consideration if you value GLD's liquidity for frequent trading. On a $1,000,000 position, the difference is $23,000 — a compelling reason to choose BAR or SGOL over GLD for a strategic hold.

Tax Treatment: The Collectibles Rule

This is the single most important tax fact every gold ETF investor must know: physical gold ETFs (GLD, IAU, SGOL, BAR) are classified as collectibles by the IRS.

What this means in practice:

  • Maximum federal capital gains tax rate: 28% (regardless of holding period)
  • Long-term equity/bond ETF max rate: 20% (for high earners)
  • The standard 20% long-term capital gains rate does not apply to gold ETFs
  • State taxes apply on top of the 28% federal rate in most states
  • Collectibles tax applies whether you hold for 1 day or 30 years

For investors in the 37% income tax bracket, gains on gold ETFs held long-term face 28% federal tax (not 20%). The difference: a $50,000 gain costs $14,000 in federal tax under collectibles treatment vs. $10,000 under the preferential rate — a $4,000 difference that may justify holding gold ETFs in a tax-deferred IRA account where collectibles treatment is irrelevant during the accumulation phase.

IRA Strategy

Holding gold ETFs inside a traditional or Roth IRA eliminates the collectibles tax problem during the accumulation phase. In a Roth IRA, gains are tax-free. In a traditional IRA, gains are deferred and taxed as ordinary income on withdrawal — which may actually be worse than collectibles rates for high earners. The right account depends on your expected retirement tax bracket.

The Decision Framework: Which ETF Should You Choose?

Match Your Situation to the Right ETF

You trade actively and need maximum liquidity GLD
You're a buy-and-hold investor focused on total return IAU
You want the lowest annual cost and trade infrequently BAR or SGOL
You want gold stored outside US/UK jurisdiction SGOL
You're investing through a Roth or traditional IRA IAU (liquidity advantage for periodic rebalancing)
Your position is under $50,000 IAU (lower share price makes DCA practical)
Your position is over $500,000 Split: SGOL or BAR for the cost savings, GLD for liquid portion
You want physical gold access in an emergency Physical bars/coins — ETFs don't give retail investors direct redemption

Alternatives to Physical Gold ETFs

Gold ETFs are not the only way to invest in gold. Here is where they fit in the broader investment landscape:

Investment Type Exposure Leverage Best For Key Risk
Physical Gold ETF (GLD, IAU, etc.) 1:1 to gold price None Core allocation, IRAs, long-term holds Collectibles tax; no physical possession
Physical Bars/Coins 1:1 to gold price None Systemic hedge, no counterparty risk Premiums (3–8%); storage costs; less liquid
Gold Miners ETF (GDX, GDXJ) ~2–3x gold price move Operational leverage Aggressive bull play; valuation-driven investing Management risk; mine costs; political risk
Gold Futures (COMEX) Direct; rollover required High (initial margin ~6%) Hedging; professional traders Roll costs; margin calls; complexity
Gold Streaming Companies (RGLD, WPM) Indirect; equity exposure Financial leverage Dividend income + gold exposure Company-specific risk; premium valuation

Frequently Asked Questions

Is GLD actually backed by physical gold?
Yes. GLD is fully backed by physical allocated gold bars held in HSBC's London vault. Each bar is individually identified by serial number, weight, and purity in bar lists published on the SPDR website. The gold undergoes annual audits. However, "allocated" in this context means the gold is clearly assigned to GLD, not that individual shareholders own specific bars — redemption of physical gold is only available to Authorized Participants in 100,000-share blocks.
Will gold ETFs track gold price exactly?
Very closely but not perfectly. The tracking error is the difference between the ETF's net asset value (NAV) return and gold's spot price return. This gap is primarily caused by the expense ratio being deducted from the gold held. Over time, an ETF holding 0.93 oz of gold per 10 shares slowly "erodes" due to fees. Over 10 years, IAU's 0.25% fee means it will hold approximately 2.5% less gold per share than on inception. This is the true long-term cost of ETF ownership.
Can I convert my gold ETF shares into physical gold?
Not directly as a retail investor. Authorized Participants (large financial institutions) can redeem ETF shares for physical gold in large basket sizes (typically 100,000 shares for GLD = roughly 9,312 oz = 290 kg). Individual retail investors must sell their ETF shares on the market and use proceeds to buy physical gold separately. SGOL offers a slightly lower minimum for APs but still not for retail investors.
Should I choose GLD or IAU for my IRA?
IAU is typically better for IRA investors. The lower share price ($50 vs $460) makes it easier to invest specific dollar amounts and rebalance over time. The 0.25% expense ratio vs. GLD's 0.40% saves $150 per year on every $100,000 — meaningful over a multi-decade retirement accumulation period. Both are IRA-eligible and held by all major custodians.
What happens to my gold ETF if the ETF issuer goes bankrupt?
The gold is legally segregated from the issuer's assets. In bankruptcy, the fund's physical gold would be distributed to shareholders (via the Authorized Participant mechanism). This is meaningfully different from a bank deposit where the bank can rehypothecate your assets. That said, the custodian (e.g., HSBC, JPMorgan) also carries counterparty risk — if the custodian failed, the gold's legal separation from their assets becomes crucial. Gold ETF trust documents typically specify allocated gold that is not encumbered by the custodian's other liabilities.
