Where You Buy Gold Determines Your Return — Physical vs. KRX vs. Gold ETFs, Fully Compared

You've probably heard the saying that "gold rises every time there's a crisis." In fact, gold has been used for centuries as an asset to hedge against inflation and currency debasement. But once you actually decide to "give gold a try," there are too many paths. Should you buy a gold bar at a jewelry shop, open the KRX gold market in your brokerage app, or load up on a gold ETF? This article compares the cost, taxes, and convenience of the three approaches by the numbers, so you can find the entry point that fits your situation. (This is for reference only and is not a recommendation to buy or sell any specific product.)

Why hold a little gold in your portfolio

Gold itself pays no interest or dividends. In other words, it's less of an asset that 'earns money for you' and more of an asset that 'preserves value.' The key point is that its price tends to move differently from stocks and bonds (low correlation), so it's used as a diversification tool that lowers the volatility of your overall portfolio. For example, if you have 10 million KRW and split it into 7 million in stocks, 2 million in bonds, and 1 million in gold, gold can act as a buffer during periods when stocks swing sharply. That said, gold is also an asset with high short-term volatility, so it's a misconception to think 'it's a safe asset, so it never falls.'

Method 1 — Physical gold (gold bars and coins)

Being able to see it and hold it in your hand is both its biggest advantage and its biggest drawback. Physical gold carries a 10% value-added tax (VAT) when you buy it. So if the gold is worth 1 million KRW at the spot price, you'll have to pay about 1.1 million KRW to buy it. On top of that come the craftsmanship fees and sales margin of the jewelry shop or bank (usually around 5%), and when you sell it back, you also face a spread where they buy it at a price lower than the purchase price. In effect, you start out roughly 15% in the hole versus the spot price the moment you buy, so it suits 'holding physical gold for the long term' rather than seeking short-term gains. Storage and theft risks are an added bonus.

Method 2 — The KRX gold market (trading by the gram through a brokerage account)

This is a physical gold spot market operated by the Korea Exchange (KRX), where you buy and sell in 1g units just like stocks through your brokerage app. The biggest appeal is the taxes. Trading gains generated on the KRX gold market are exempt from capital gains tax and dividend income tax, and they are also not included in the comprehensive financial income tax. Trading commissions vary by brokerage but are roughly 0.2–0.3%, far cheaper than physical gold. For example, if gold is 100,000 KRW per gram and you buy 100g (about 10 million KRW), and it rises to 120,000 KRW per gram, the 2 million KRW gain is subject to virtually no tax. However, if you withdraw the gold you bought as a physical gold bar, a 10% VAT is levied at that point.

Method 3 — Gold ETFs and gold funds (index/price-tracking products)

This is a way of trading, like stocks, funds designed to track the price of gold (or a gold futures index). The advantages are that they're easy to hold in small, diversified amounts and offer good liquidity. In exchange, a management fee (roughly 0.3–0.7% per year) is deducted annually, and trading gains on domestically listed gold ETFs are subject to a 15.4% dividend income tax and may be included in the comprehensive financial income tax. For example, if your gain is 1 million KRW, about 154,000 KRW goes out in taxes. You also need to check that the impact of the KRW/USD exchange rate differs depending on whether the product is 'currency-hedged or unhedged.'

At a glance — cost, taxes, and convenience

• Physical gold: 10% VAT plus a margin when buying, heavy storage burden; trading gains are tax-exempt but entry and exit costs are the highest → for long-term physical holders
• KRX gold market: commission of about 0.2–0.3%, trading gains tax-exempt and excluded from comprehensive taxation, small amounts possible in 1g units → the most tax-efficient (VAT only on physical withdrawal)
• Gold ETFs/funds: excellent for small amounts, diversification, and liquidity; management fee of 0.3–0.7% per year; trading gains taxed at 15.4% dividend income tax → convenient but incurs taxes and fees
• Common: all three pay no interest or dividends, carry price-fluctuation risk, and are investment products not covered by depositor protection (50 million KRW)

Confirming the tax difference in numbers

Let's assume you put in the same 10 million KRW and, a year later, you have a gain of 2 million KRW (20%). On the KRX gold market, trading gains are tax-exempt, so the tax is effectively close to 0 KRW. By contrast, a domestic gold ETF applies a 15.4% dividend income tax to the 2 million KRW gain, deducting about 308,000 KRW, leaving an after-tax profit of about 1.69 million KRW. With physical gold, you already paid around 15% in VAT and margin when you bought it, so even with the same price movement the break-even point itself is higher. Even with the same 'gold,' the result changes quite a bit depending on which vessel you put it in.

So who should choose what

1. If you want to accumulate efficiently with cost and taxes as your top priority → the KRX gold market (open a brokerage account and buy in 1g units, splitting your purchases)
2. If you want to manage it simply with a small amount, alongside your other ETFs → a gold ETF (factoring in the management fee and 15.4% dividend income tax)
3. If you find meaning in 'physical holding' as a hedge against the monetary system itself → a gold bar (offsetting entry and exit costs through long-term holding)

In short, even with the same gold investment, the cost structure and taxes are completely different, so 'choosing your entry point' becomes part of your return. Generally, the KRX gold market is the most tax-efficient, ETFs offer the most convenience, and gold bars provide the reassurance of the physical asset. Whatever you choose, it's safer to keep gold in a supporting role in your portfolio and start with a small weight.
