Gold ETFs vs Physical Gold: What Every Wealth Advisor Should Know

When a client asks whether to buy physical gold or a gold ETF, the right answer depends on factors most advisors underweight: custody structure, counterparty risk, liquidity profile, and tax treatment. Here is the full picture.

The question comes up in almost every high-net-worth client conversation eventually: should I own physical gold or a gold ETF? Most advisors default to the ETF on the grounds of liquidity, cost, and simplicity. That is often the right answer. But a blanket recommendation without understanding the structural differences is not advisable practice — and increasingly, sophisticated clients know enough to push back. ## What a physically-backed gold ETF actually holds The major gold ETFs — SPDR Gold Shares (GLD), iShares Gold Trust (IAU), WisdomTree Physical Gold (PHAU) — are backed by physical gold held in allocated form at approved custodians. The gold is Good Delivery bars held in LBMA-approved vaults, primarily in London. The key word is allocated. This is not an unallocated credit. The bars are segregated, identified by serial number, and held for the benefit of ETF shareholders. Counterparty risk is substantially limited compared to an unallocated account at a bullion bank. The custodian (typically HSBC or JP Morgan) cannot lend or hypothecate the gold. However, there are important structural nuances. Most physically-backed gold ETFs use a custodian network that includes sub-custodians — banks and vaults that hold gold on behalf of the primary custodian. The legal chain between the ETF share and a specific gold bar is real but involves multiple institutional links. ## The case for physical ownership For clients whose primary objective is wealth preservation outside the financial system, physical ownership has structural advantages that an ETF cannot replicate. Physical gold in a private vault — either home storage for small quantities or a private secure storage facility for larger holdings — eliminates all institutional intermediaries. There is no custodian to fail, no ETF trust to wind down, no counterparty of any kind. The gold is simply there. For very high net worth clients building a meaningful position — say, 5% or more of a multi-million pound portfolio — the cost differential between ETF management fees (typically 15–40 basis points per year) and private vault storage (often 10–20 basis points per year at scale) can also favour direct ownership over a long holding period. The disadvantages of physical ownership are real: lower liquidity, storage and insurance cost, no dividend or lending income, and complexity in estate planning. For most retail and mass-affluent clients, these disadvantages outweigh the benefits of direct ownership. ## Tax treatment differences In many jurisdictions, gold ETFs and physical gold are taxed differently, and the differences can be material. In the UK, physical gold coins that are legal tender — such as Britannia coins and Sovereigns — are exempt from Capital Gains Tax. No ETF structure offers this. For UK clients with meaningful CGT exposure, the after-tax return on Britannia coins may be substantially better than on an equivalent ETF position, even accounting for the higher buy-sell spread on coins. In the US, both physical gold and gold ETFs are taxed as collectibles under Section 408(m) of the Internal Revenue Code, with a maximum long-term capital gains rate of 28% — higher than the 20% maximum rate on equities. But the mechanics of how gains are realised differ between direct ownership and ETF rebalancing events. Advisors need to understand these nuances in their jurisdiction before making a recommendation. Getting it wrong is a compliance risk, not just a financial one. ## What the conversation with clients should look like The right framework for the physical versus ETF conversation starts with three questions. What is the client's primary objective — return, wealth preservation, or portfolio diversification? What is their liquidity requirement — are they likely to need to liquidate within five years? And what is their comfort with institutional intermediaries? A client who answers "wealth preservation outside the financial system," "no near-term liquidity need," and "low comfort with intermediaries" is a candidate for physical. A client who answers "portfolio diversification," "may need to rebalance frequently," and "comfortable with institutional custody" is a strong candidate for a physically-backed ETF. Most clients are somewhere in the middle. The advisor's job is to map the structure to the objective, not to default to the most convenient recommendation.
