MONEY EXPLAINED: The Evolution of Value

To even try to understand finance, markets, or currency, we first have to understand what money actually is and what it does.

Money

Money is simply a technology we use to solve a problem. In economics, we say money serves three main functions: it’s a Store of Value (saving for later), a Unit of Account (pricing things), and a Medium of Exchange (buying things).

So, how did this work before paper and metal currency? Money is referred to as “the most marketable commodity,” which means that which is most “marketable” is usually that which most people want/find value in.

The Problem of Barter

People would literally exchange goods for other goods or services. Person A would give Person B a chair, and Person B would give Person A a bushel of grain. This is called barter. But people realized that as populations grew and more goods became available, this method didn’t really work at scale. You run into what economists call the “Coincidence of Wants” problem—if you have a chair but I don’t want a chair, we can’t trade, even if I have the grain you need.

Plus, the value in these items could decay over time (grain rots, chairs break). So, we decided to invent a new way of storing value. Instead of value being stored in the item itself, what if we paid for the item with a smaller, tangible asset like gold or silver? In fact, some of the earliest forms of money included salt, grains, beads, and livestock. Now, what is the common denominator you see here? It’s that these are items that are extremely marketable (most people want them) and relatively easy to store without degrading their value.

Gold and silver have inherent value because they are extremely rare, durable, and used in jewelry and decor. Since scarcity + demand = value, gold became the global “currency.” Now gold represented time and labor, so people could trade with it accordingly.

The Two Towers: Inflation and Deflation Explained

Imagine we have two towers representing all the resources in the world.

• Tower 1 (Money): All the gold currently available (e.g., 1,000 gold coins). • Tower 2 (Goods): All the goods and services, represented here by wheat (e.g., 1,000 bushels).

If we try to measure the value of the wheat in gold, we can map 1 gold coin = 1 bushel of wheat.

Scenario A: Supply-Side Deflation (Good for buyers, bad for debtors)

Comes the next harvest, and there is a surplus. Now we have 2,000 bushels of wheat but still only 1,000 gold coins. This causes deflation because the supply of goods has increased relative to the money. Now, 1 gold coin buys 2 bushels of wheat. The money has become more powerful.

Scenario B: Supply-Side Inflation (Bad for buyers, good for debtors)

Imagine a worse harvest than usual. Now there are only 500 bushels of wheat. It would now take 2 gold coins to buy 1 bushel. The value of the money has been diluted because the goods are scarce.

Why does this matter for loans?

Let’s say you borrow 200 gold coins to buy wheat and sell it overseas.

• If Deflation happens (Good Harvest): Your 200 borrowed coins are now worth a huge amount of wheat. But wait—you have to pay back the loan in coins. Since the coins are so valuable now, you have to sell twice as much wheat just to get the 200 coins back to pay your debt. This is why deflation is crushing for people with debt. • If Inflation happens (Bad Harvest): The wheat price skyrockets. You can sell just a little bit of wheat, easily get 200 coins, and pay back the loan with change to spare. This is why inflation is great for debtors but bad for savers.

In the modern world, technology constantly makes goods and services cheaper and more accessible (natural deflation). To keep things fair, central banks try to manage the money supply to keep prices stable.

The Velocity of Money

How does the economy grow besides just mining more gold? It turns out, the more money moves around, the more value one gold coin can “capture.”

If Person A buys a house from Person B, and Person B buys fish from Person C, and Person C buys a chair… that single gold coin changed hands 3 times, but 3 coins worth of economic value was generated.

This is called the Velocity of Money. Economic output (GDP) isn’t just how much money exists ($M$), but how fast it moves ($V$).

The formula economists use is:

$$M \times V = P \times Q$$

(Money Supply × Velocity = Average Price × Quantity of Goods)

So, there are two ways for economic output to grow: increase the money supply, or increase the speed at which money changes hands.

Venice: The Birth of The Bond Market

In 1171, the Byzantine Empire seized the goods and ships of Venetian merchants. Venice needed to go to war, but they needed to build a massive fleet of ships. This cost more than they collected in taxes.

So, the government forced the wealthy to lend them gold. In exchange, the government gave them an IOU with a set interest rate (called prestiti). This was one of the first true government bonds. Eventually, these IOUs started being circulated to pay for things. Venice had effectively increased the money supply without finding more gold!

This created the first bond market. The value of this “money” fluctuated based on trust. If the war was going poorly, the value of the bond/IOU would drop because people feared the government would never pay it back. If the war went well, the value went up. Money became a measure of trust in the state.

The Rise of Fractional Reserve Banking

Later, in London, the early bankers were actually goldsmiths. A merchant would give the goldsmith, say, 10 gold coins for safekeeping. In exchange, he received a paper receipt to claim the coins back. Now these paper receipts were of course easier to carry than the heavy gold, so people started using the receipts as money.

Then slowly the goldsmiths noticed a pattern: most people never withdrew their gold at the same time.

So, they started loaning out 9 of the 10 coins sitting in the vault. They would lend a gold coin to someone else, who would usually just deposit it right back into the vault (or another bank’s vault) for a receipt.

This creates what’s called a Multiplier Effect:

> 10 coins get deposited -> 9 are lent out -> those 9 are deposited -> 8 are lent out…

Suddenly, the original 10 gold coins might support 100 coins worth of paper receipts circulating in the economy. This is Fractional Reserve Banking. The money supply is now backed by a mix of real gold and debt.

THE CREATION OF FIAT MONEY & THE CENTRAL BANK

After the goldsmiths proved you could create money out of thin air, the Government realized they wanted in on the action.

Initially, the system was fragile because it relied on the whim of kings. In 1640, King Charles I of England shattered public trust when he seized the merchants’ gold stored at the Tower of London to fund a war. He essentially told them, “I’m borrowing this indefinitely.” This theft pushed merchants to move their gold to private bankers, birthing the private banking system.

But by 1694, the government needed money for a massive war with France. The King couldn’t borrow from anyone because his credit was terrible. So, the government made a deal with the wealthy merchants that changed the world: they created the Bank of England.

They invented a “Magic Trick” to turn Debt into Money:

1. The Bond: The Government wrote an IOU (a Bond) promising to pay back £1.2 million from future taxes.
2. The Print: The new Bank of England accepted this IOU. Because they held this government debt as an asset, they printed £1.2 million in paper “Bank Notes.”
3. The Spend: The Government took those notes and spent them to build ships and pay soldiers.
4. The Acceptance: Why did people trust paper? Because the Government accepted it back for taxes.

This was the moment Debt became Money. The cash in your pocket wasn’t just gold anymore; it was a share of the government’s debt.

HOW THE FEDERAL RESERVE CREATES “BASE MONEY”

Today, this system is run by the Central Bank (The Fed). To understand how they create money, you have to understand the difference between Base Money and Bank Money.

Think of the money supply like an inverted pyramid.

• Bank Money (The Top): This is the vast majority of money. It’s the credit and loans created by private banks (like Chase or Wells Fargo) using the multiplier effect we talked about earlier. • Base Money (The Bottom Tip): This is the only “real” money created by the Central Bank. It consists of physical cash and the digital reserves banks keep at the Fed.

The Magic Checkbook (How Borrowing Creates Base Money)

When the government spends more than it collects in taxes, it issues a Bond. Here is the modern version of the magic trick:

1. The Borrowing: A private bank buys the government bond.
2. The Monetization: The Fed sees the economy needs cash, so it buys that bond from the private bank.
3. The Creation: The Fed doesn’t pay with money it already has. It simply types numbers into a computer, crediting the bank’s account with brand new Base Money that didn’t exist five seconds ago.

The Bond goes into the Fed’s vault, and new money flows into the economy.

IS THIS JUST “PRINTING MONEY”? (The Debt Distinction)

You might be thinking: “Wait, isn’t this just printing money like Zimbabwe?”

Technically, no. It is Monetizing Debt. The difference is subtle but critical.

When a failed state prints money, they print paper backed by nothing. In our system, every new dollar created is backed by a Bond—a promise of future taxes.

This means that for every dollar that exists, there is a dollar of debt somewhere on a ledger. In theory, this process is reversible. Money enters the world when a loan is made (creation), and money vanishes from the world when the loan is repaid (destruction). If the government paid off the national debt, the money supply would actually shrink.

When the Fed holds a government bond, the dollars it created to buy that bond exist as bank reserves in the system. If that bond later gets repaid and the Fed decides not to reinvest, those dollars “go home” and disappear. The Treasury pays the Fed using dollars that sit in banks’ reserve accounts; then the Fed simply marks down its assets (the bond is gone) and its liabilities (those reserves) by the same amount. From the banks’ point of view, their reserve balances just got smaller, and no one else received those dollars—so they are effectively deleted from the monetary base. In other words, the Fed can create new dollars when it buys assets and can un‑create them when those assets are allowed to run off instead of being rolled over.

WORLD WAR II: THE PROOF IT WORKS

To see this in action, look at World War II. The US Government issued massive amounts of bonds to fund the war. The Fed increased the money supply to buy them, nearly doubling the amount of dollars in circulation.

Going back to our Two Towers model:

• Tower 1 (Money) doubled in height.

Normally, if you double the money but the amount of stuff (Tower 2) stays the same, prices should double (Inflation). But that didn’t happen. Why?

• Because Tower 2 (Goods) also doubled. American manufacturing went into overdrive to build tanks, planes, and food. The economic output (GDP) grew fast enough to “soak up” all the new dollars. This proved that you can expand the money supply without destroying the currency—but only if the economy actually produces more value to match it.

Bretton Woods & The Triffin Dilemma

In 1944, at a conference in Bretton Woods, New Hampshire, the world decided to peg global currencies to the US Dollar, and the US Dollar was pegged to gold at $35 an ounce.

But then America started overspending (on the military, domestic programs, etc.), printing more dollars than they had gold to back up. This created a paradox known as the Triffin Dilemma:

• To support global trade, the US had to print tons of dollars so other countries could use them. • But the more dollars they printed, the less likely it was that they had enough gold to redeem them all.

Foreign countries (like France) called America’s bluff. They started redeeming their dollars for actual gold bars. The US gold reserves began to empty rapidly.

America faced two choices:

1. Stop printing dollars and raise interest rates (which would crash the US economy and stop global trade).
2. Cut the link to gold entirely.

In 1971, President Nixon chose option 2. He took the dollar off the gold standard.

This made the entire world players in America’s carnival, where the rides and games only run on tickets (dollars) that the US government can print at will. We entered the age of Fiat Money—money that is valuable not because it is gold, but because the government says it is.

Summary:

We moved from:

• Barter (inefficient) to commodity money (gold/wheat). • We learned that deflation favors savers, and inflation favors debtors. • Venice taught us that debt (bonds) can act like money. • Goldsmiths taught us we can multiply money via fractional reserve banking. • Finally, we severed the link to gold entirely, leaving us with a system based on government debt and trust.
