What is gold spread? Why is it wider than Forex spread?

Opening the XAU/USD chart for the first time after trading currency pairs like EUR/USD for a while, many people are struck by the same number: the spread is clearly wider than what they're used to, sometimes several times wider. The question that follows is: Is this an anomaly with the broker they're using, or is this just how gold is?

The answer is that gold is indeed like this, and there are structural reasons to support it; it's not a coincidence or a broker taking advantage. This article will explain all the mechanisms, from definitions and calculation methods to factors that cause the spread to widen significantly at certain times, without referring to any specific broker.

What is Gold Spread (XAU/USD)?

Gold spread is the difference between the Bid price (the price at which the market buys from you) and the Ask price (the price at which the market sells to you) for the XAU/USD pair at any given moment. It's an implicit cost incurred as soon as you open an order, whether buying or selling, and it's independent of which direction the price moves next.

According to the definition used by the U.S. Securities and Exchange Commission, spread is "the difference between the bid and ask prices," which is a mechanism market makers use to profit from matching buyers and sellers (SEC Reference). This principle applies to all two-way market assets, not just gold, but the size of the spread will vary depending on the nature of the asset.

A common point of confusion is the unit of measurement. Forex currency pairs like EUR/USD measure spread in pips (4th or 5th decimal place), but gold is measured in points or cents per ounce. This is because gold prices are quoted per troy ounce, not as a currency exchange rate. Therefore, the numbers seen on platforms have different units from the outset and cannot be directly compared without conversion.

How to Calculate Gold Spread Cost

The basic formula is: Spread = Ask Price minus Bid Price, then multiplied by the contract size traded.

Suppose the Bid price is $2,650.00 per ounce and the Ask price is $2,650.35. The spread here is $0.35, or 35 points (each point = $0.01 per ounce in most standard references).

If trading 1 standard lot (equivalent to 100 troy ounces according to most CFD contracts), the spread cost for this order is 0.35 x 100 = $35 per round trip (opening and closing). Converting this to Thai Baht at an exchange rate of approximately 35 Baht per dollar, it comes to about 1,225 Baht per round trip. This is the cost incurred before the price moves in any direction.

These figures are for illustrative purposes only. Actual spreads change constantly according to market conditions, and each platform may use different standard contract sizes. What you should do is check the real-time spread on your chosen platform at the moment you intend to trade, not rely on figures seen long ago.

Why is Gold Spread Wider Than Typical Forex Currency Pair Spreads?

To illustrate clearly, currency pairs like EUR/USD might have a spread of only 0.1 to 1 pip during periods of good liquidity, whereas XAU/USD is typically at least 15 to 35 points during normal times. This isn't because gold is "more expensive," but because the market structures are fundamentally different.

Three main reasons explain this gap:

First, liquidity depth. The global foreign exchange market has a daily trading volume many times higher than the spot gold market. According to data from the Bank for International Settlements, global forex trading volume is heavily concentrated during London trading hours, which accounts for a larger share of global turnover than all other countries combined (BIS Triennial Survey 2025 Reference). While gold is also traded in vast quantities, it is distributed across various markets, including futures, spot, and CFDs, meaning the depth of the order book on each platform is not equivalent to that of major currency markets.

Second, market maker pricing behavior. Gold generally has higher price volatility per unit of time than major currency pairs. Market makers therefore set wider spreads to compensate for the risk of sharp price movements while holding short-term positions before matching buy and sell orders.

Third, price reference unit. As mentioned above, gold is quoted in dollars per ounce, not as an exchange rate. Therefore, the monetary value of a price movement per point is much higher than a pip movement in typical currency pairs. The visible per-unit cost on screen naturally appears higher, even if the percentage cost of the contract value might not differ as much as the raw numbers suggest.

Factors That Cause Gold Spreads to Widen Significantly

In addition to the inherently wider basic spread compared to currency pairs, there are certain times when gold spreads expand even further. This is something you should know in advance before planning to enter an order.

During the Asian market open and before the New York market opens, liquidity is not yet at its peak because the main trading centers for both forex and gold, London and New York, are not yet simultaneously open. Spreads during these times are therefore often wider than during the London-New York overlap, which is the period of highest liquidity during the day.

During significant U.S. economic data releases, such as Non-Farm Payrolls (NFP) or the Consumer Price Index (CPI), gold often reacts strongly to these announcements because its price is directly tied to interest rate trends and the value of the U.S. dollar. Market makers will temporarily widen spreads in the minutes before and after such announcements to mitigate the risk from unpredictable volatility.

Each platform's liquidity policy. Even with identical market factors, platforms connected to multiple liquidity providers often have narrower average spreads than platforms relying on a single provider. This is why gold spreads between two platforms at the same time might not be exactly equal, even if they are referencing the same market price.

How to Check Gold Spreads Before Trading to Avoid Disadvantage

Before opening a real gold order, there are things you should always check without relying on any platform's advertisements.

Check the live spread on the platform you are actually using, not the "average" figures advertised. Advertised figures are often the lowest values during periods of best liquidity, not what you'll encounter all the time. Note the time you intend to trade and compare the spread you see then with the major market overlap periods mentioned above. Avoid opening new orders in the 5 to 10 minutes before and after major economic data releases, unless you specifically intend to trade the news. And calculate the spread cost in actual monetary terms based on the size of the order you plan to open, not just by looking at the number of points, because 20 points with different lot sizes will result in vastly different actual costs.

As for checking the overall trustworthiness of the platform you are using, beyond just the spread, that is a separate step. It should be done in conjunction but is not the same issue.

Frequently Asked Questions

Note: Forex trading is not yet licensed or regulated by any agency in Thailand. The Bank of Thailand does not have a policy to issue licenses for Forex business to retail investors (Thai PBS Reference), and the SEC itself confirms that Forex business is not under the supervision of the SEC but rather under currency exchange control laws (The Standard Reference).

What is Spread and How Does it Differ from Commission?

Spread is the difference between the Bid and Ask prices directly embedded in the prices seen on screen. Commission, on the other hand, is a separate fee charged per trade. Some platforms choose to collect only a wider spread instead of commission, while others collect both in smaller proportions. The true total cost must consider both components, not just one.

Why Do Gold Spreads Widen Instantly at Certain Times?

This mostly occurs due to temporary decreases in liquidity, whether it's during periods when major markets are not simultaneously open, close to significant economic news announcements, or during holidays in some major markets. Market makers will widen spreads to compensate for the increased risk from unpredictable volatility during those times.

How Much Initial Capital is Needed to Trade Gold?

This depends on the contract size supported by the platform and the leverage ratio chosen. There is no fixed figure applicable to all platforms. What you should do is calculate based on the actual lot size you intend to trade, multiplied by the margin required by the platform, and then set aside reserve funds to accommodate volatility, rather than just using the minimum capital needed to open an order.

What's the Difference Between Fixed and Floating Spreads?

A fixed spread remains the same regardless of market conditions, suitable for those who want to know their costs precisely in advance. A floating spread, on the other hand, changes according to actual market liquidity, narrowing during periods of good liquidity and widening during low liquidity. Most gold trading in the CFD market uses a floating spread system because liquidity changes significantly with time, as explained above.

Check Everything Before Trading Gold

Gold spreads are wider than typical Forex currency pairs due to explainable structural reasons, not by coincidence. What you can do is understand this mechanism and plan your order entry times to avoid unnecessarily wide spreads.
