Gold ETFs, physical bars, paper gold: three routes, and who eats your return

Everyone here is bullish gold. One buys a 1 kg bar and locks it in a safe, one buys 300 shares of GLD, one clicks a few buttons in a bank app to buy "account gold", and one just trades XAUUSD. All four may hold exactly the same view on the gold price — and ten years later their accounts will be far apart. What separates them is not foresight; it is cost structure.

This article does not argue about whether to own gold. It does one thing: takes the four holding methods apart layer by layer and prices each one at today's real gold price. By the end you should be able to answer three questions. How much am I paying the intermediaries each year? How much do I get back when I exit? And how will this asset be treated under my tax residency?

1. Four ways to "buy gold" that are not the same asset

Most comparison articles start with returns. That is the wrong start, because these four instruments have completely different legal natures and their risks do not sit in the same place.

The difference is invisible in calm markets and is everything in an extreme. In March 2020, when liquidity tightened, the spread between London spot and New York futures widened abnormally and some market makers pulled quotes; at the same moment retail buyers of physical bars faced delivery delays of more than two weeks. Holders of "paper gold" discovered in that instant that they owned a promise, not metal.

This is not an argument that paper gold is bad. Its liquidity, cost and convenience beat physical by a wide margin, and an ETF satisfies most allocation needs. But you should know what you are buying, rather than assuming "I bought gold" means "I own gold".

2. Cost layer one: the bid/ask spread, the widest gap of all

Start with the cleanest benchmark. Today XAUAD quotes 4,120.54 bid and 4,121.19 ask — a spread of 0.66 USD/oz, or 0.016% of price. Scaled to 1 kg (32.1507 oz), one round trip costs 21 USD, about 142 in local currency.

Now physical. Gold is worth 886.84 per gram today, but buy a 1 kg investment bar at a jewellery shop or bank and the counter quote is usually 920 to 950 per gram — a 4% to 7% premium. The reason is not greed; every link in the chain costs money:

• Refining and minting: melting a 400 oz institutional bar into a 1 kg standard bar involves fabrication cost and metal loss.
• Transport and insurance: armoured delivery, armed guards, all-risk insurance, priced on cargo value.
• Distribution and inventory: branch rent, capital tied up in stock, sales staff.
• Tax treatment: some jurisdictions exempt investment bars from VAT while jewellery is taxed — part of the reason jewellery carries a 15%–30% premium.

Exit is harder still. On buy-back the dealer re-assays the metal, may re-melt and assay it, and takes on price risk, so the price you receive is typically 1% to 3% below the posted selling price. Buy at a 5% premium and sell at a 1.5% discount and you have a fixed 6.5% loss. On a 100,000 USD position, 6,500 USD is gone before the gold price moves at all.

3. Cost layer two: holding cost, the annual scalpel

Gold ETF: 0.10% to 0.40% a year

ETF costs are disclosed in the fund documents as a management fee or total expense ratio (TER), deducted daily from fund assets. You never see it, but it genuinely reduces the gold backing each unit. The spread between mainstream products is not small:

A 4x difference in fee is 3,000 USD over ten years. Many people pick the most expensive fund tracking the same thing purely because it is the best known and has the easiest ticker — the most avoidable payment there is. The ETF carries one further invisible cost: tracking difference. Net asset value equals the market value of vaulted bars minus accrued expenses, so the long-run path is structurally "gold price minus fee". That is by design, not manager error.

Physical bars: storage and insurance

At home, the cost is insurance plus risks you would rather not dwell on — burglary, fire, flooding — and household policies usually cap both single-item and total precious-metal cover. In a bank safe deposit box, annual fees in Hong Kong or Singapore run about 1,000 to 3,000 HKD/SGD, roughly 0.15%–0.4% a year on a 100,000 USD position. In professional allocated storage, where bar serial numbers are registered in your name, the fee is typically 0.1%–0.2% a year plus an intake fee and assay charge.

Paper gold / account gold: the spread is the cost

Bank account gold is quoted by the bank itself, with a two-way spread usually of 0.5% to 1%. That looks modest, but it is charged on every trade. Twenty trades a year costs 10% to 20% — enough to explain why account gold suits sitting still and not moving in and out.

Leveraged products: spread × frequency

XAUUSD has the lowest spread of the four at 0.016%. But leveraged costs accumulate by count: on 100,000 USD of notional exposure, 0.016% per round trip is 16 USD a trade — 1,600 USD for 100 trades a year, 8,000 USD for 500. Hold overnight and swap is added; in the current dollar rate environment the annualised cost on a long is roughly 2%–4%.

4. Cost layer three: tax, where the real gaps open up

Fees are the decimals; tax is the number before the decimal point. On the same gold gain, different tax residencies can leave you 20% or more apart.

Note the second half of the US row: for non-US tax residents holding a US-domiciled ETF, the asset counts as US-situs property, and the portion above 60,000 USD may face US federal estate tax of up to 40% on death. That rule is separate from capital gains tax, and many people who live in Asia with accounts at US brokers have no idea it exists. The usual remedy is an Irish-domiciled UCITS ETF (such as iShares Physical Gold ETC or Invesco Physical Gold), which is not US-situs and has a dividend withholding structure friendlier to non-US residents.

Germany's "exempt after one year" cuts the other way: if you are in Germany, the tax advantage on physical bars can offset that 6.5% trading cost. So the question "which is cheaper" cannot be answered without first adding the premise "which tax jurisdiction are you in".

5. Liquidity: can it become cash when you need it

Beyond cost there is a dimension that is routinely underestimated: how fast it converts to cash, and whether you get priced down when it does.

• ETF: sell any time during the session, settle T+1 to T+2, at a spread close to the matched market price. When you need money urgently this is the smoothest route.
• Physical bars: appointment, assay, sometimes re-melting — usually 1 to 3 business days, and you must bring the original invoice and intact packaging. Many channels refuse bars without an invoice outright.
• Bank account gold: a few clicks and it is credited, but only in bank hours, and some banks suspend quotes in extreme markets — as happened in 2008 and 2020.
• XAUUSD: closable 24 hours, the best liquidity, but leverage magnifies volatility and it is unsuited to being a store of value.

The appeal of physical gold is that it depends on nobody; the price of that is also that it depends on nobody — on the day you actually need the money, you still have to find someone willing to take it.

6. Three types of investor, three answers

1. Long-term preservation, untouched for 5+ years

Prefer the ETF (0.10%–0.25% fee) and reinvest what you save. If your tax jurisdiction gives physical metal a clear advantage (Germany after one year, UK gold coins CGT-free), or you genuinely need "assets physically outside the financial system", add some physical — no more than a third of the gold allocation. When you do buy physical, buy 1 kg standard bars or mainstream 1 oz coins, not fabricated jewellery: that 15%–30% premium is consumption, not investment.

2. Swing trading, short horizons

An ETF works, but watch the session and the premium. Better still, judge direction from the spot quote and use the session table to find the London–New York overlap. The biggest short-term cost is not the spread, it is frequency — work out how many trades a year you plan before choosing the instrument.

3. Large amounts, cross-border, multi-currency

This is where the word "convenient" leads people astray. The questions that matter: which jurisdiction the account sits in, whose name the assets are registered in, how inheritance is handled, and whether the money trail is documented. A brokerage account holding an ETF, a safe deposit box holding bars, and an offshore bank account have completely different compliance meanings. For cross-border funding, read compliant routes and red lines for buying gold from overseas before acting.

7. The maths on three real scenarios

Scenario A: 50,000 USD, intended for 8 years

ETF (0.25%): cumulative fees about 1,000 USD. Physical (5% premium + 1.5% discount + 0.15% a year storage): 2,500 + 750 + 600 = 3,850 USD. The 2,850 USD difference equals a 5.7% move in the gold price. Unless you have a clear tax reason to hold physical, that 5.7% is given away for nothing.

Scenario B: 200,000 USD, intended for the children

Here the focus shifts from fees to inheritance. A US-domiciled ETF exposes non-residents to the 60,000 USD estate tax exemption; on a 200,000 USD position the rate can take a double-digit percentage of principal. All else equal, an Irish-domiciled UCITS ETC, or holding physical registered to a trust or in joint names, is usually more controllable. This step is worth a few hundred dollars of advice.

Scenario C: 1,000 USD a month, accumulated

The enemy of regular investing is a fixed fee per trade. At a 5 USD commission, 12 trades a year is 60 USD — 0.5% of 12,000, more than the management fee. Use a zero-commission broker or switch to quarterly purchases and the cost drops immediately. Physical accumulation is basically unworkable: every purchase eats a 5% premium.

8. The five most common miscalculations

1. Using the jewellery price as your investment cost. Jewellery carries a 15%–30% premium and the fabrication fee goes to zero on resale. That is consumption, not allocation.
2. Looking at the management fee and not the spread. A 0.10% fee and a 6% round-trip spread are not the same order of magnitude — check the big item first.
3. Forgetting the currency layer. Buy dollar-priced gold in Singapore with SGD and your return mixes in the exchange rate. Unbundled, gold may have risen 1% while FX contributed 3%. The conversion method is in converting between USD and local-currency gold prices.
4. Assuming the ETF must track gold exactly. Long term it must lag by the fee; short term there are premiums and discounts, and market orders in volatile conditions can incur 1% slippage.
5. Ignoring the friction on the sell side. Everyone optimises the purchase, then discovers on exit that the invoice is lost, the packaging is open, or the channel will not take it.

9. Frequently asked

Q. Over a long holding period, is a gold ETF or physical bullion cheaper?
A. On 100,000 USD of exposure: physical costs a 5% retail premium on entry and a 1.5% buy-back discount on exit, so roughly 6,500 USD disappears on the first round trip before any safe deposit box; an ETF charges an annual 0.10%–0.40%, or 1,000–4,000 USD over ten years. Beyond about five years the ETF is usually clearly cheaper, unless your tax jurisdiction gives physical a specific advantage or you genuinely need the asset outside the financial system.

Q. What is the difference between paper gold and a gold ETF?
A. Paper gold is a liability the bank owes you: no delivery, quotes set by the bank on both sides, a spread usually of 0.5%–1%, and exposure to bank credit. An ETF is a fund unit backed by physical bars in a vault, matched on an exchange at a spread close to market, in exchange for an annual fee. The first is convenient and bank-dependent; the second is transparent and dependent on the fund and custody structure.

Q. Who do I sell physical bars to, and how much do I lose?
A. Three channels: the original seller, a local bullion dealer or pawnshop, and online buy-back platforms. The original seller usually takes only its own brand, requires the invoice and intact packaging, and discounts 1%–3%; dealers and pawnshops discount 3%–8% and assay on site. Without an invoice, with damaged packaging or for a bar from another institution, many channels refuse outright — the most underestimated cost of physical gold.

Q. Are there tax traps for overseas Chinese buying gold ETFs?
A. Yes, chiefly US estate tax: US-situs assets held by non-US tax residents (including US-domiciled gold ETFs) above 60,000 USD may face federal estate tax of up to 40% on inheritance. The US also classifies physical gold and gold ETFs as collectibles, with long-term capital gains up to 28% versus 20% for ordinary assets. Confirm your specific position with a licensed local tax adviser.

Q. Can an ETF drift away from the gold price?
A. There is tracking difference, but it is structurally predictable: NAV equals the market value of vaulted bars minus accrued fees, so a 0.25% fee means a 10% gold rally shows up as roughly 9.75% in the ETF. Secondary-market premiums and discounts are normally within 0.1% and can widen past 1% in violent moves — when they do, limit orders are safer than market orders.
