When investing in precious metals, the price of gold or silver is often the first thing that comes to mind. But for South African investors, there’s another important factor that can influence the value of these investments: the rand.
Gold and silver are traded internationally, with their prices typically quoted in US dollars. However, when purchasing physical precious metals in South Africa, investors pay in rands. This means that fluctuations in the exchange rate can directly influence the local price of gold and silver, even when international market prices remain relatively stable.
Understanding this relationship can help investors make more informed decisions when buying, holding or selling precious metals.
Why Are Precious Metals Priced in US Dollars?
Gold and silver are globally traded commodities, bought and sold across international markets.
Their benchmark prices, commonly referred to as spot prices, are typically quoted in US dollars per troy ounce. A troy ounce is the standard unit of measurement used in precious metals trading and is equivalent to approximately 31.1 grams.
Because these metals are traded internationally, their prices are influenced by several global factors, including:
- Supply and demand across international markets.
- Inflation and interest rate expectations.
- Geopolitical uncertainty and economic conditions.
- Central bank activity, particularly in the gold market.
- Industrial demand, especially for silver.
While these factors help determine international precious metal prices, South African investors must also consider how those prices translate into rands.
The Relationship Between the Rand and Gold Prices
The rand-dollar exchange rate plays an important role in determining the local price of precious metals.
When the rand weakens against the US dollar, the rand price of gold and silver generally increases, assuming international metal prices remain unchanged.
Conversely, when the rand strengthens, the local price of these metals may decrease, even if their international prices remain stable.
To understand how this works, consider a simplified example.
Imagine the international gold price is $4,000 per troy ounce.
| Exchange rate | Gold price in rands |
|---|---|
| R16 to $1 | R64,000 |
| R17 to $1 | R68,000 |
| R18 to $1 | R72,000 |
| R19 to $1 | R76,000 |
These figures are hypothetical and intended for illustration only. They exclude premiums, manufacturing costs and other applicable charges.
In this example, the international gold price hasn’t changed. Yet the rand value of one ounce of gold increases significantly as the local currency weakens.
This demonstrates why South African investors may experience changes in the value of their precious metals even when global prices appear relatively unchanged.
Why Local Gold and Silver Prices Don’t Always Follow Global Trends
One of the more interesting aspects of investing in precious metals from South Africa is that local prices don’t always move in the same direction, or by the same percentage, as international prices.
For example, the international gold price could decline while the rand weakens against the dollar.
In this situation, the weaker rand may offset some or all of the decline in the international gold price. Depending on the extent of the currency movement, the rand price of gold could remain relatively stable or even increase.
The opposite can also happen.
Gold may experience a strong increase internationally, but if the rand strengthens significantly during the same period, South African investors might see a smaller increase in the local price.
This means that the performance of precious metals in South Africa is influenced by both the metal’s international price and the value of the rand.
Understanding these two factors provides a more complete picture of how precious metals are priced locally.
What Does This Mean for Silver Investors?
Although gold often receives the most attention, the same currency principles apply to silver.
Silver is internationally priced in US dollars, meaning its value in South Africa is also affected by movements in the rand-dollar exchange rate.
However, silver has another important characteristic: its significant industrial demand.
Beyond its role as a precious metal investment, silver is used in electronics, solar technology, automotive manufacturing and various other industries.
As a result, silver prices can be influenced by both investment activity and changes in industrial demand.
For South African investors, this creates an interesting combination of factors to consider.
The local price of silver may be affected by global economic activity, industrial demand, investor sentiment and currency fluctuations, all at the same time.
Can Precious Metals Offer Protection Against Rand Weakness?
One reason investors consider physical gold and silver is their potential to provide exposure to assets whose international values are not determined solely by the South African economy.
Because precious metals are globally traded, their rand-denominated values can rise when the local currency weakens.
This can make them an interesting consideration for investors looking to diversify their holdings beyond rand-based assets.
However, it’s important to understand that precious metals are not a guaranteed hedge against currency depreciation.
Gold and silver prices fluctuate, and changes in international metal prices can outweigh the effects of currency movements.
For example, a significant decline in the global gold price could result in a lower rand value even if the rand has weakened.
Precious metals should therefore be considered within the context of an investor’s broader financial objectives, investment horizon and tolerance for market fluctuations.
What Should South African Investors Consider Before Buying?
When purchasing physical gold or silver, looking at the international spot price alone doesn’t provide the complete picture.
There are several factors worth considering:
1. The international metal price
Understanding the current global price of gold or silver provides a useful starting point when evaluating a purchase.
2. The rand-dollar exchange rate
Currency movements influence how international prices translate into local values. A change in the exchange rate can affect the price paid in rands.
3. The physical product being purchased
Gold and silver bars, coins and medallions may carry different premiums depending on their weight, manufacturing requirements, availability and other factors.
4. The difference between buying and selling prices
The price paid when purchasing a physical precious metal product may differ from the amount received when selling it. Understanding this difference is important when considering potential returns.
5. Your long-term investment objectives
Rather than focusing exclusively on short-term price movements, investors should consider how physical precious metals may fit into their broader financial plans.
Understanding the Bigger Picture
For South African investors, precious metals are influenced by more than international market performance.
The relationship between global metal prices and the rand-dollar exchange rate means that local gold and silver prices can behave differently from what international headlines might suggest.
A stronger or weaker rand can influence the cost of purchasing precious metals, as well as their rand-denominated value over time.
