Consumer credit may seem like a fairly new invention – but it’s actually been around for more than 5,000 years!
In fact, many millennia before the credit score became ubiquitous, there is historical evidence that cultures around the world were borrowing for various reasons. From the writings in Hammurabi’s Code to the exchanges documented by the Ancient Romans, we know that credit was used for purposes such as getting enough silver to buy a property or for agricultural loans made to farmers.
Consumer Credit: 3,500 B.C. to Today
In today’s infographic from Equifax, we look at the long history of consumer credit – everything from the earliest writings of antiquity to the modern credit boom that started in the 20th century.
Consumer credit has evolved considerably from the early days.
Over the course of several millennia, there have been credit booms, game-changing innovations, and even periods such as the Dark Ages when the practice of charging interest (also known as “usury”) was considered immoral by some people.
A Timeline of Consumer Credit
Below is a timeline of the significant events that have helped lead to the modern consumer credit boom, in which Americans now have over $12.4 trillion borrowed through mortgages, credit cards, student loans, auto loans, and other types of credit.
The Ancients and Credit
3,500 BC – Sumer
Sumer was the first urban civilization – with about 89% of its population living in cities. It is thought that here consumer loans, used for agricultural purposes, were first used.
1,800 BC – Babylon
The Code of Hammurabi was written, formalizing the first known laws around credit. Hammurabi established the maximum interest rates that could be used legally: 33.3% per year on loans of grain, and 20% per year on loans of silver. To be valid, loans had to be witnessed by a public official and recorded as a contract.
50 BC – The Roman Republic
Around this time, Cicero noted that his neighbor bought 625 acres of land for 11.5 million sesterces.
Did this person literally carry 11.5 tons of coins through the streets of Rome? No, it was done through credit and paper. Cicero writes “nomina facit, negotium conficit” – or, “he uses credit to complete the purchase”.
Moral Concerns About Lending
800 – The Dark Ages in Europe
After the collapse of the Western Roman Empire, economic activity grinded to a halt. The Church even banned usury, the practice of charging interest on loans, for all laymen under Charlemagne’s rule (768-814 AD).
1500 – The Age of Discovery
As European explorers and merchants begin trade missions to faraway lands, the need for capital and credit increases.
1545 – England
After the Reformation, the first country to establish a legal rate of interest was England in 1545 during the reign of Henry VIII. The rate was set at 10%.
1787 – England
Philosopher Jeremy Bentham writes a treatise called “A Defense of Usury”, arguing that restrictions on interest rates harm the ability to raise capital for innovation. If risky, new ventures cannot be funded, then growth becomes limited.
The Birth of Modern Consumer Credit
1803 – England
Credit reporting itself originated in England in the early 19th century. The earliest available account is that of a group of English tailors that came together to swap information on customers who failed to settle their debts.
1826 – England
The Manchester Guardian Society is formed, and later begins issuing a monthly newsletter with information about people who fail to pay their debts.
1841 – New York
The Mercantile Agency is founded, and starts systemizing rumors about the character and assets held by debtors through a network of correspondents. Massive ledgers in New York City are made, though these reports were heavily subjective and biased.
1864 – New York
The Mercantile Agency is renamed the R. G. Dun and Company on the eve of the Civil War, and finalizes an alphanumeric system for tracking creditworthiness of companies that would remain in use until the twentieth century.
1899 – Atlanta
The Retail Credit Company was founded, and begins compiling an extensive list of creditworthy customers. Later on, the company would change its name to Equifax. Today, it is the oldest of the three major credit agencies today in the United States.
The Consumer Credit Boom
1908 – Detroit
Henry Ford’s Model T makes automobiles accessible to the “great multitude” of people, but they were still too expensive to buy with cash for most families.
1919 – Detroit
GM solves this problem by loaning consumers the money they need to buy a new car. General Motors Acceptance Corporation (GMAC) is founded and popularizes the idea of installment plan financing. Consumers can now get a new car with just a 35% downpayment at time of financing.
1930 – United States
By this time, efficient U.S. factories are pumping out cheaper consumer products and appliances. Following the lead of GM, now washing machines, furniture, refrigerators, phonographs, and radios can be bought on installment plans. It’s also worth noting that in this period, 2/3 of all autos are bought on installment plans.
The First in Big Data
1950 – United States
By 1950, typical middle-class Americans already had revolving credit accounts at different merchants. Maintaining several different cards and monthly payments was inconvenient, and created a new opportunity.
At the same time, Diners Club introduces their charge card, which helps open the floodgates for other consumer credit products.
1955 – United States
Early credit reporters use millions of index cards, sorted in a massive filing system, to keep track of consumers around the country. To get the latest information, agencies would scour local newspapers for notices of arrests, promotions, marriages, and deaths, attaching this information to individual credit files.
1958 – United States
BankAmericard (now Visa) is “dropped” in Fresno, California. American Express and Mastercard soon follow, offering Americans general credit for a wide range of purchases.
1960 – United States
At a time when the technology was limited to filing cabinets, the postage meter, and the telephone, American credit bureaus issued 60 million credit reports in a single year.
1964– United States
The Association of Credit Bureaus in the U.S. conducts the first studies into the application of computer technologies to credit reporting. Accuracy of data is also improved around this time by standardizing credit application forms.
1970 – United States
The first Fair Credit Reporting Act is passed in the United States. It establishes a standard legal framework for credit reporting agencies.
1980s – United States
The three biggest credit bureaus attain universal coverage across the country.
1989 – United States
The FICO score is introduced, and quickly becomes a standard system to measure credit scores based on objective factors and data.
2006 – United States
VantageScore is created through a joint-venture between the top three credit scoring agencies. This new consumer credit-scoring model is used by 10% of the market, and 6 of the 10 largest banks use VantageScore.
The Information Age has enabled a new era in consumer credit and assessing risk – and today, credit reports are used to inform decisions about housing, employment, insurance, and the cost of utilities.

Ranked: The World’s Top Diamond Mining Countries, by Carats and Value
Who are the leaders in rough diamond production and how much is their diamond output worth?
Ranked: World Diamond Mining By Country, Carat, and Value
Only 22 countries in the world engage in rough diamond production—also known as uncut, raw or natural diamonds—mining for them from deposits within their territories.
This chart, by Sam Parker illustrates the leaders in rough diamond production by weight and value. It uses data from Kimberly Process (an international certification organization) along with estimates by Dr. Ashok Damarupurshad, a precious metals and diamond specialist in South Africa.
Rough Diamond Production, By Weight
Russia takes the top spot as the world’s largest rough diamond producer, mining close to 42 million carats in 2022, well ahead of its peers.
Russia’s large lead over second-place Botswana (24.8 million carats) and third-ranked Canada (16.2 million carats) indicates that the country’s diamond production is circumventing sanctions due to the difficulties in tracing a diamond’s origin.
Here’s a quick breakdown of rough diamond production in the world.
|5||🇿🇦 South Africa||9,660,233|
|10||🇸🇱 Sierra Leone||688,970|
|18||🇨🇮 Cote D'Ivoire||3,904|
|19||🇨🇬 Republic of Congo||3,534|
Note: South Africa’s figures are estimated.
As with most other resources, (oil, gold, uranium), rough diamond production is distributed unequally. The top 10 rough diamond producing countries by weight account for 99.2% of all rough diamonds mined in 2022.
Diamond Mining, by Country
However, higher carat mined doesn’t necessarily mean better value for the diamond. Other factors like the cut, color, and clarity also influence a diamond’s value.
Here’s a quick breakdown of diamond production by value (USD) in 2022.
|5||🇿🇦 South Africa||$1,538M|
|9||🇸🇱 Sierra Leone||$143M|
|19||🇨🇬 Republic of Congo||$0.20M|
|20||🇨🇮 Cote D'Ivoire||$0.16M|
Note: South Africa’s figures are estimated. Furthermore, numbers have been rounded and may not sum to the total.
Thus, even though Botswana only produced 59% of Russia’s diamond weight in 2022, it had a trade value of nearly $5 billion, approximately 1.5 times higher than Russia’s for the same year.
Another example is Angola, which is ranked 6th in diamond production, but 3rd in diamond value.
Both countries (as well as South Africa, Canada, and Namibia) produce gem-quality rough diamonds versus countries like Russia and the DRC whose diamonds are produced mainly for industrial use.
Which Regions Produce the Most Diamonds in 2022?
Unsurprisingly, Africa is the largest rough diamond producing region, accounting for 51% of output by weight, and 66% by value.
|Rank||Region||Share of Rough|

However diamond mining in Africa is a relatively recent phenomenon, fewer than 200 years old. Diamonds had been discovered—and prized—as far back as 2,000 years ago in India, later on spreading west to Egyptian pharaohs and the Roman Empire.
By the start of the 20th century, diamond production on a large scale took off: first in South Africa, and decades later in other African countries. In fact between 1889–1959, Africa produced 98% of the world’s diamonds.
And in the latter half of the 20th century, the term blood diamond evolved from diamonds mined in African conflict zones used to finance insurgency or crime.
