In an era where the global economy is filled with uncertainty, inflation quietly erodes our savings like an invisible hand, while the volatility of the stock market makes investors uneasy. Are you looking for an asset that can weather financial storms? Gold, this ancient metal passed down through millennia, is always mentioned at critical moments. But do you truly understand the reasons gold preserves value? What is the underlying logic behind the relationship between inflation and gold? And why do US dollar trends have such a profound influence on gold prices? This article will take you through an in-depth analysis of the core secrets behind gold’s ability to preserve value, helping you fully understand these three key factors and providing a solid foundation for your investment decisions.
The value of gold does not appear out of thin air; it is rooted in its unique physical and historical attributes. For thousands of years, regardless of changes in dynasties or the evolution of monetary systems, gold has remained the dominant store of value. Understanding these three core attributes is the basis for grasping the movements of gold prices.
The first layer of gold’s value comes from its “rarity”. The total amount of gold on Earth is limited, and extraction is extremely difficult and costly. According to estimates from the World Gold Council, all the gold ever mined in human history could only fill a cube with sides of about 22 meters. This physical scarcity prevents gold from being created at will like fiat currency, fundamentally eliminating the risk of value dilution caused by excessive issuance. ⛏️
More importantly, gold carries a “historical consensus” that transcends cultures and borders. From ancient Egyptian pharaohs to modern central banks, gold has long been regarded as the ultimate medium of payment and a symbol of wealth. This deeply rooted collective trust gives gold an irreplaceable monetary attribute, making it the most reliable measure of value when confidence in paper currency wavers.
When markets are calm, gold’s brilliance may be overshadowed by yield-generating assets such as stocks and bonds. However, once geopolitical conflicts erupt (such as wars or trade disputes) or systemic risks appear in financial markets (such as the 2008 financial crisis), investors instinctively seek a safe haven. This is gold’s “safe-haven function”.
During periods of fear, investors sell off risk assets and turn to what is perceived as the safest option. Since gold is not the liability of any nation or corporation, its value is unaffected by the credit risk of any single economy, making it a globally recognized ultimate safe-haven asset. This surge in demand during times of crisis often drives gold prices sharply higher in a short period, creating the phenomenon known as “buying gold in troubled times”.
Beyond serving as an investment and reserve asset, gold also carries broad and stable demand in the physical world, providing a solid foundation for its price. This demand is primarily divided into two major segments:
This diversified demand structure ensures that gold prices are not determined solely by investor sentiment, but are influenced jointly by investment, consumer, and industrial demand, ultimately enhancing the stability of its value.
“Buy gold to fight inflation” is a phrase many people are familiar with. When prices rise and the purchasing power of cash keeps shrinking, can gold truly protect our wealth? The answer is yes, but the mechanism behind it is more intricate than most imagine.
The essence of inflation is an excessive supply of money, causing “money to lose its value”. Suppose NT$100 could buy a basket of goods last year, but this year it takes NT$105 to buy the same basket. This means the purchasing power of money has declined. Gold is priced in currency (such as USD per ounce), so when the currency itself depreciates, it naturally takes more of that currency to buy the same amount of gold, which is directly reflected in the rise of gold prices.
From another perspective, gold’s intrinsic value (based on its rarity and other attributes) remains relatively stable. Therefore, during periods of high inflation, the rise in gold prices is essentially a reflection of its ability to maintain its original purchasing power, effectively hedging the risk of currency depreciation.

However, judging gold price trends solely based on inflation can sometimes be inaccurate. A more precise indicator, and one that professional investors closely monitor, is the real interest rate.
Real Interest Rate = Nominal Interest Rate – Inflation Rate
This formula represents the actual return you earn when depositing money in a bank or purchasing bonds after accounting for inflation. Gold itself is a “non-yielding asset”, meaning it does not generate interest or dividends. Therefore, the “opportunity cost” of holding gold becomes particularly important.
Therefore, instead of saying gold hedges “inflation”, it is more accurate to say that gold hedges a “negative real interest rate” environment. This also explains why gold prices can sometimes fall during periods of high inflation when central banks are aggressively raising interest rates.
In the global market, gold and the US dollar often behave like two partners on a seesaw, typically showing a negative correlation “when one rises, the other tends to fall”. This phenomenon stems from two key factors that must be understood when analyzing how US dollar trends influence gold prices.
The standard quotation for gold in global markets is USD per ounce. This means that when the US dollar appreciates against other currencies (such as the euro, yen, or New Taiwan dollar), the cost of buying gold becomes more expensive for international buyers holding those currencies. For example, even if gold’s USD price remains unchanged, a stronger US dollar forces foreign investors to spend more of their local currency to exchange for enough USD to purchase gold. This suppresses part of the international demand and puts downward pressure on gold prices.
Conversely, when the US dollar weakens, gold becomes cheaper for investors outside the US dollar zone, stimulating demand and pushing up gold prices in USD terms.
The US dollar and gold share another layer of competition: both are globally recognized “safe-haven assets”.
Therefore, when market risk aversion rises, capital chooses between the US dollar and gold. If the crisis originates outside the US, funds may flow preferentially into the US dollar. But if the crisis stems from within the US itself, or if confidence in the global fiat currency system weakens, gold’s appeal may greatly surpass that of the US dollar. This delicate competitive relationship is key to understanding the seesaw effect between the two.
Interest rate hikes or cuts primarily affect gold prices through their influence on the “real interest rate”. In general:
Rate hikes tend to raise nominal interest rates. If inflation is under control, this pushes real interest rates higher, increasing the opportunity cost of holding gold and putting pressure on gold prices.
Rate cuts tend to lower nominal interest rates, potentially causing real interest rates to fall or turn negative, reducing the opportunity cost of holding gold and benefiting gold prices. However, this is not absolute; market reactions still depend on inflation expectations and broader economic outlook at the time.
Gold prices are affected by a wide range of factors. In addition to the core topics discussed in this article, such as inflation and the US dollar, the following also play important roles:
There is no standard answer to this question, as it depends on your investment goals, risk tolerance, and portfolio composition. Rather than trying to “time the market”, it is better to view gold as a long-term, strategic asset allocation tool. Gold’s primary role in a portfolio is risk diversification. With its relatively low correlation to mainstream assets such as stocks and bonds, it can serve as a stabilizer during market volatility. Investors are generally advised to allocate a certain proportion of their assets to gold (for example, 5%–10%) based on their financial situation, rather than concentrating all funds in one asset.
Different gold investment channels suit different investor needs:
In summary, the reasons gold preserves value are rooted in its three core attributes that have endured for thousands of years: rarity and historical consensus, a powerful safe-haven function, and diversified physical demand. During periods of high inflation, gold can effectively hedge the risk of currency depreciation, especially when real interest rates are low or negative, making its value-preserving function particularly evident. At the same time, gold prices and US dollar trends generally exhibit an inverse, seesaw-like relationship, driven both by pricing effects and the competitive dynamic between the two as safe-haven assets. A deep understanding of these three core concepts forms the foundation for making sound gold investment decisions. Investors are advised to continuously monitor changes in global macroeconomic data and regard gold as an important allocation for risk diversification and portfolio balance, rather than a tool for short-term speculation.
