What Is Purchasing Power? Why Your Dollar Buys Less Every Year — And What Gold Does About It
WHAT IT MEANS
Purchasing power is the quantity of goods and services that a unit of currency can buy. When purchasing power declines, your dollar buys less. When it increases, your dollar buys more. In a fiat currency system with central bank-targeted inflation, purchasing power is designed to decline over time.
A dollar in 1970 had the purchasing power equivalent of roughly $8 today. That means the same basket of groceries, the same gallon of gas, the same month of rent that cost $100 in 1970 costs approximately $800 today. The dollar did not change — its purchasing power eroded by over 85%.
This erosion is not a bug in the system. Central banks target approximately 2% annual inflation as a policy goal. That 2% compounds: after 10 years, your purchasing power has declined by roughly 18%. After 20 years, roughly 33%. After 35 years, roughly 50%. The dollar in your wallet today will buy about half as much in 2060 as it does now — by design.
WHY IT MATTERS FOR INVESTORS
Purchasing power preservation is the fundamental reason people own precious metals. Not speculation. Not trading. Preservation — ensuring that the value you have earned retains its ability to buy goods and services across years and decades.
Savings accounts, bonds, and cash holdings all lose purchasing power in an inflationary environment. A savings account paying 4% during 3.5% inflation preserves purchasing power — barely. A savings account paying 1% during 3.5% inflation loses 2.5% of purchasing power annually. And these are the good scenarios — during periods of financial repression (rates held below inflation), the erosion accelerates.
Gold has maintained purchasing power over centuries. An ounce of gold in ancient Rome bought a fine toga and sandals. An ounce of gold today buys a quality suit and shoes. The goods changed; the purchasing power did not. Over shorter periods — decades — gold has consistently outpaced inflation, preserving and often enhancing the purchasing power of holders.
HOW IT CONNECTS TO PRECIOUS METALS
At Alex Lexington, purchasing power preservation is the core message to every client. We do not sell gold as a get-rich-quick scheme or a speculative trade. We position it as what it is: a proven store of value that protects purchasing power against the systematic erosion built into every fiat currency system.
For vault storage clients, the math is clear. Metal stored today at current prices will retain its purchasing power over the coming decades. Cash held in a bank account — even with interest — will lose a significant portion of its real value to inflation over the same period. The vault storage fee is the cost of protecting purchasing power that would otherwise evaporate.
The most powerful illustration: a client who stored 50 oz of gold in 2004 at roughly $400/oz paid $20,000. Twenty years later, that gold is worth over $145,000. The gold did not generate a return — it maintained purchasing power while the dollar lost roughly 40% of its value. The apparent "gain" is primarily the dollar's loss, measured in gold.
THE BOTTOM LINE
Purchasing power is what your money can actually buy. Under fiat currency systems, it declines every year by design. Gold preserves purchasing power across decades and centuries — not because gold goes up, but because fiat currencies go down. The decision is simple: hold your wealth in an asset designed to lose value, or hold it in one that has preserved value for thousands of years.
