Gold Bid-Ask Spread Explained: Why You Sell for Less Than You Pay
Buy a small bar in the morning, walk back into the same shop an hour later and ask what they would pay for it, and the answer will be lower than what you paid, even if the world gold price has barely moved. That gap is not a trick. It is the bid-ask spread, and it exists in every gold market in the world.
Understanding the spread helps you choose the right product, compare dealers fairly and know how far the price must rise before you make any money. Here is what it is, why it exists, how to measure it and how to keep it small.
What is the bid-ask spread?
Every dealer quotes two prices at any moment: the ask (or offer), which is what you pay to buy, and the bid, which is what the dealer pays when you sell. The difference is the spread, expressed in dirhams or as a percentage:
- Spread = ask − bid.
- Spread % = (spread ÷ ask) × 100.
A hypothetical example: if a bar is offered at 400 dirhams a gram and bid at 390, the spread is 10 dirhams a gram, or 2.5% of the ask.
Why the spread exists
- Price risk: gold bought from you may fall before the dealer resells it.
- Running costs: rent, staff, insurance and security.
- Testing and refining: used jewellery is often melted and refined, which takes time and money.
- Financing: stock on the shelf is money tied up.
That is why spreads between banks in the wholesale market are tiny, with huge volumes and low costs per ounce, and why they widen the smaller the deal and the closer it gets to the consumer.
What makes the spread wider
- Small sizes: casting and packing a 1 g bar costs almost as much as a larger one, so it is a bigger share of the value. Our guide to gold bar sizes and premiums compares the options.
- Product type: commemorative coins and designer pieces carry higher premiums than plain bars.
- Refiner reputation: bars from well-known accredited refiners are easier to resell, so dealers buy them back on tighter terms.
- Volatility: on big news days dealers widen spreads to protect themselves from fast moves.
- Weekend closures: when international markets are shut, some dealers add a safety margin because prices can gap when trading resumes.
- Condition: a bar without its original packaging or certificate may need testing and fetch a lower bid.
Jewellery: the bigger hidden spread
With jewellery the gap goes beyond the gram price. You pay the gold value, the making charge and VAT when you buy, but when you sell you are usually paid only for the raw gold at the dealer’s bid. The round-trip cost of jewellery is therefore far higher than for bars, which is fair enough: you are paying for design and craftsmanship you get to wear, not just for metal.
Work out your round-trip cost
The clearest way to compare products is to ask what you would lose if you bought and immediately sold, with no change in the gold price. Hypothetical figures:
| Product | You pay | You get back at once | Round-trip cost |
|---|---|---|---|
| 10 g bar | AED 3,600 | AED 3,500 | AED 100 (2.8%) |
| 100 g bar | AED 35,500 | AED 35,000 | AED 500 (1.4%) |
| 20 g 21K bracelet | AED 7,140 | AED 5,900 | AED 1,240 (about 17%) |
The dealer’s bid has to rise by enough to cover that cost before you are in profit. For the 10 g bar, the bid per gram must climb from 350 to 360 dirhams, about 2.9%.
How to keep the spread small
- Ask for the buying and selling price at the same moment, and compare two or three dealers.
- Check quotes against the live reference: 1 gram of 24K is 480.81 dirhams right now on our UAE gold price page, and the further a quote strays from it, the more you pay.
- If you are saving rather than buying to wear, favour bars from recognised refiners over pieces with high making charges, and do not split your budget into very small bars without a reason.
- Keep the original packaging, certificate and invoice; they make resale easier and better priced.
- Avoid buying or selling in a rush during sharp market swings unless you have to.
- If you buy in instalments, factor the spread into each purchase, as our guide to regular gold buying explains.
This is general information, not financial advice, and the figures above are hypothetical illustrations.
Frequently asked questions
Is a dealer’s spread fixed all day?
Not always. Both prices move with the international price during the day, and the spread itself can widen in volatile spells or around market closures.
Why do some dealers pay more than others when I sell?
Costs and stock needs differ. A dealer who needs a particular type of bar may pay more for it, which is why it is worth asking more than one shop before you sell.
Does a narrow spread always mean a better deal?
Usually, as long as the selling price itself is close to the reference price. Some offers show a narrow spread on top of an inflated base price, so always compare what you pay with what you would get back, in actual numbers.
The spread is a real cost, just like a making charge. Knowing it before you buy helps you pick the right product and the right dealer for your goal, whether that is wearing gold or saving in it.
