Does a rise in gold prices guarantee a profit after buying paper gold? Not necessarily. Returns on paper gold depend not only on changes in gold prices but also on the bid-ask spread. Even if gold prices rise, investors may still incur a loss if the price increase is insufficient to offset the cost of the spread. Understanding how the bid-ask spread affects returns can help investors better assess trading costs and potential profits or losses.

Key Features of Paper Gold Trading

Paper gold is an account-based gold investment product offered by banks and other financial institutions. Investors buy and sell gold holdings through the trading channels provided by these institutions, with profits and losses determined by changes in transaction prices. Such products generally do not involve the physical withdrawal or delivery of gold.

Unlike physical gold investments, paper gold does not require investors to hold gold bars or coins. Instead, trading results depend primarily on the prices at which investors buy and sell. In addition to monitoring movements in gold prices, investors should also understand the quoted prices and associated trading costs.

How the Bid-Ask Spread Works

The bid-ask spread is the difference between an institution's selling price and buying price at the same point in time.

From an investor's perspective, buying paper gold typically means purchasing at the institution's selling price, while selling it means receiving the institution's buying price. Because these two prices may differ, an investor could incur a loss from the spread alone when buying and immediately reselling paper gold, even if the market price has barely changed.

For example, suppose a bank quotes a selling price of RMB 850 per gram and a buying price of RMB 848 per gram for paper gold at the same time. The selling price is the price at which the investor buys, while the buying price is the price at which the investor sells. The difference of RMB 2 per gram represents the bid-ask spread.

How Does the Bid-Ask Spread Affect Investment Returns?

Suppose an investor buys 100 grams of paper gold at RMB 850 per gram, for a total purchase cost of RMB 85,000. If the market price remains broadly unchanged and the investor sells at RMB 848 per gram, the proceeds will amount to RMB 84,800, resulting in a loss of RMB 200.

In this example, gold prices have barely changed, yet the bid-ask spread has already resulted in a loss. Even if gold prices subsequently rise, the investor may not immediately make a profit. Ignoring other fees and charges, the selling price received by the investor must exceed the original purchase price for the trade to be profitable.

The profit or loss from a paper gold transaction can be calculated using the following formula:

Trading Profit or Loss = (Selling Price ? Purchase Price) × Quantity Traded (grams)

Note: The selling price refers to the bank's buying price when the investor sells paper gold, while the purchase price refers to the bank's selling price when the investor buys it.

Under otherwise identical conditions, a wider bid-ask spread generally means higher initial trading costs for investors, while a narrower spread generally means lower costs.

The Bid-Ask Spread and Trading Costs

From a trading cost perspective, a narrower bid-ask spread is generally more favorable to investors. However, when comparing different paper gold products, investors should also consider the pricing structure, transaction fees and any other applicable charges. The spread alone does not provide a complete picture of the overall cost.

The bid-ask spread may also vary depending on market conditions, trading hours and the pricing policies of individual institutions. Before trading, investors should check the institution's latest quoted buying and selling prices, as well as its fee schedule and relevant product terms.

It is important to note that paper gold and spot gold differ in their product structures, trading mechanisms and applicable rules. Investors should refer to the official information provided by the relevant institution or trading platform for specific product details.

Understanding the bid-ask spread helps investors assess trading costs more comprehensively, but it does not predict the direction of gold prices. Investors should evaluate market conditions carefully and remain mindful of the risks involved. This article is for educational purposes only and does not constitute investment advice.
