Coins, gold bars and bills swirling along a ribbon of light in a stone hall

Money, plainly

Where money comes from

Most money is created the moment someone takes a loan.

5,000 years of the record, from clay-tablet debts to Bitcoin. And barter never came first.

The origin story

Barter didn't come first

The textbook: Adam Smith, 1776: people swapped goods, barter was clumsy, so they invented money.
The fieldwork: Anthropologist Caroline Humphrey, 1985: no pure barter economy has ever been described, and none where money grew out of one.
What they found: Barter shows up between strangers, or where money has broken down. Neighbors ran on credit: you owe me.

Debt came before coins

On clay: Mesopotamian temples kept accounts about 5,000 years ago. Signed loan contracts on clay are about 4,000 years old.
The shekel: A weight before it was a coin: about 8 grams of silver, set equal in temple books to a measure of barley.
A legal cap: Hammurabi's laws, about 3,800 years ago, capped interest: 20% a year on silver, 33⅓% on grain.

Coins: a stamp you could trust

Where: Lydia and the Greek cities of western Turkey, more than 2,600 years ago. Lumps of electrum, a gold-silver alloy.
The proof: The oldest dated hoard lay under the Temple of Artemis at Ephesus. Herodotus credits the Lydians with the first coins.
What it changed: A stamp vouched for weight and purity, so strangers could pay without weighing metal each time.

China prints paper money

The problem: Sichuan, about 1,000 years ago, paid in iron coins. A thousand of them weighed several kilograms.
The fix: Merchants issued paper receipts, called jiaozi, that could be exchanged for coin. People traded the receipts instead.
The state steps in: When private issuers failed, the Song government took over in 1023 and ran its own note office.

Marco Polo sees money from bark

What he wrote: Kublai Khan's mint pressed mulberry bark into sheets, signed by officials and stamped in red. Everyone had to accept them.
The rule: Counterfeiting meant death, Polo reported. Gold and silver went to the state in exchange for paper.
How it ended: Wars were paid for with new notes. Prices rose about 140-fold in 96 years. By 1368, people bartered.

1933 to 1944

The gold standard and its end

Gold standard: A dollar was defined as a fixed weight of gold, and paper notes were a claim on that gold.
1933 and 1934: Americans were ordered to turn in gold coin. The government reset the price from $20.67 to $35 an ounce.
Bretton Woods, 1944: 44 nations pegged their currencies to the dollar. Foreign governments could swap dollars for US gold at $35.

Fiat money

What happened: President Nixon closed the gold window. Foreign governments could no longer trade dollars for US gold.
Fiat, plainly: Latin for "let it be done." Money by law, accepted for taxes and debts, with no claim on any metal.
The tradeoff: Central banks can respond fast in a crisis. The same freedom lets prices rise when money grows faster than goods.

Where new money comes from

Bank of England, 2014: "The majority of money in the modern economy is created by commercial banks making loans."
How: When a bank lends, it types a new deposit into the borrower's account. That deposit is new money.
And back: Repaying the loan erases that money. Limits remain: capital rules, profit, and how many people want to borrow.

What the textbook gets wrong

The textbook: Fractional reserve: banks keep a slice of your deposit and lend out the rest, multiplying reserves into more money.
The central bank: The Bank of England says the multiplier story gets the order backward. Loans come first; deposits and reserves follow.
The US rule: Since March 26, 2020, the Fed's reserve requirement is 0%. Capital and liquidity rules do the limiting now.

What a 1913 dollar is worth

The index: The US consumer price index begins in 1913 at 9.9. Its 2025 yearly average was 321.9.
The math: What cost $1 in 1913 took about $32.50 in 2025. A 1913 dollar now buys about 3 cents' worth.
Who it hits: Wages and assets rose over the same years. The steadiest loss falls on cash left sitting idle.

A 1494 tool: the Rule of 72

Pacioli, 1494: Divide 72 by a yearly rate to get the years it takes to double. At 6%, about 12 years.
Savings and wages: At 3% inflation, prices double in about 24 years. A raise or return below that loses ground.
Debt: An unpaid balance at 24% doubles in about 3 years. The same rule works for you or against you.

Money with no bank

The paper: A paper signed Satoshi Nakamoto proposed electronic cash sent person to person, "without going through a financial institution."
Its answer: A public ledger kept by many computers at once, and a fixed issuance schedule written into code.
Next: Bitcoin and sovereignty: what the design does, what it costs, and what it risks.
