What influences the price of 18-carat gold in GBP?
Multiple factors can simultaneously influence gold prices. Here, we examine some of the key factors:
Exchange Rate Variations
Since gold is primarily denominated in USD, fluctuations in the GBP-USD exchange rate affect the cost of gold for UK investors. For instance, if the GBP strengthens against the USD, gold becomes relatively cheaper in the UK. Conversely, if the GBP weakens, the cost of gold in the UK increases.
The supply of gold
The global gold supply also impacts the price of 18-carat gold in GBP. For example, if there is a disruption in the gold supply, the price in GBP could rise due to reduced availability to meet investor demand.
Demand from investors
The price of 18-carat gold in GBP is also sensitive to changes in investor demand. However, many investors may prefer higher-carat gold, such as 22-carat, because it typically has a higher resale value and is often seen as a better option for long-term investment.
U.S. Federal Reserve policies
The Federal Reserve's policies can influence gold prices through interest rates and monetary policy. Higher interest rates can lead to a decrease in gold prices, while lower interest rates and expansionary monetary policy can result in an increase in gold prices, as investors may turn to gold as a hedge against inflation.
How to calculate the 18-carat gold price in GBP
To calculate the 18-carat gold price in GBP, first convert the spot price from USD to GBP. Then, convert this price to your preferred unit of measurement if needed. Multiply the resulting number by 0.75 to account for the 75% purity level of 18-carat gold. Note that the spot price of gold is originally quoted in troy ounces in USD.
