The World’s Strangest Currencies
For centuries, humans from all around the world have tried to use different things as money. Some forms, which most people are familiar with today, have been effective catalysts for trade over thousands of years. Other currencies, from squirrel pelts to parmesan cheese, have had their time or place in human history, but were ultimately unsuccessful or made obsolete.
The path to finding the best money has been long and riddled with trial and error. Here are just some of the world’s strangest currencies that we discovered in our research.
The importance of salt to ancient civilizations cannot be understated. The first written record on salt appears in 2700 BCE in China.
Salt was highly valued for food preservation, but its production was very limited. As a result, in many places of the world, salt was used as currency.
- As early as the 6th century, Moorish merchants in sub-Saharan Africa routinely traded salt and gold at the same value per ounce.
- In what is now modern-day Ethiopia, slabs of rock salt were used as coins. Each coin was 10 inches long and two inches thick.
- Salt was also used as pay soldiers in Ancient Rome. This became known as “solarium argentum”, from which we now derive the word “salary”
- A soldier’s salary was cut if he was “not worth his salt”, a phrase that still exists today.
Bricks of tea leaves were used for currency in many places in Asia. However, it was the nomads in Mongolia and Siberia that actually preferred tea bricks to metallic coins.
Tea leaves, either whole or ground, would be dried and compressed into bricks using flour, manure, or blood. The bricks could be used as a means of exchange, or they could be eaten, used to make tea, or brewed for medicine.
In Italy, the hard, dry cheese made from skim milk is not just for pasta. It was also used as a currency.
As early as the year 1200, wheels of parmesan were used as a medium of exchange for other goods.
Even as recent as 2009, the New York Times reported some banks in the region using parmesan wheels as collateral for farmers’ loans. Each compact wheel holds the equivalent of 550 liters of milk.
In the Solomon Islands, one of the world’s strangest currencies was born: the rai stone. These limestone discs with the hole in the center were up to 12 feet in diameter and weighed up to eight tons.
It was not unusual for buyers and sellers of this currency to have their boats capsize due to their sheer weight.
Animal skins have a surprisingly important history as currency in different parts of the world.
In Russia and Finland, squirrel pelts were a key medium of exchange during medieval times. Even today, the Finnish word “raha”, which now refers to money, originally meant the “fur of squirrel”.
In North America, the European settlers and First Nations tribes found skins to be one commodity they both agreed had value.
In 1748, Beaver pelts became the “standard of trade” in the north. One pelt could buy two pounds of sugar.
Lastly, the use of buck skins in trade gave rise to “buck” as a slang word for currency, which we still use to describe dollars today.
Merging the ideas of weapons and currency is not new. Many cultures have used arrowheads as currency throughout the world.
However, Chinese “knife money” is certainly an original idea: around 600 BCE, at the time of the Zhou dynasty, these knives were inscribed with numbers or single words such as “sheep” or “fish” to determine their value.
These were used for hundreds of years, and eventually it was declared by the emperor that only circular coins with square holes could be used for Chinese currency.
What Gives a Currency Staying Power?
Currencies come and go.
Some of the world’s strangest currencies, like rai stones, did not have the staying power or value to be used universally. They would eventually fade away into the history books.
Other currencies around the world would experience hyperinflation and ultimately became worthless.
What gives a currency staying power? What makes a currency “money”?
The Money Project acknowledges that the very concept of money itself is in flux – and it seeks to answer these questions.
About the Money Project
The Money Project aims to use intuitive visualizations to explore ideas around the very concept of money itself. Founded in 2015 by Visual Capitalist and Texas Precious Metals, the Money Project will look at the evolving nature of money, and will try to answer the difficult questions that prevent us from truly understanding the role that money plays in finance, investments, and accumulating wealth.
This Infographic Breaks Down Careers In Finance, From Hedge Funds to M&A
Corporate finance oversees trillions of dollars and makes modern markets and economies possible, but who are the main players?
Careers In Corporate Finance, From Hedge Funds to M&A
Corporate finance is a key pillar on which modern markets and economies have been built. And this complex ecosystem consists of a number of important sectors, which can lead to lucrative career avenues.
From lending to investment banking, and private equity to hedge funds, the graphic above by Wall Street Prep breaks down the key finance careers and paths that people can take.
Let’s take a further look at the unique pieces of this finance ecosystem.
The Lending Business
Lending groups provide much needed capital to corporations, often in the form of term loans or revolvers. These can be part of short and long-term operations or for events less anticipated like the COVID-19 pandemic, which resulted in companies shoring up $222 billion in revolving lines of credit within the first month.
Next, is investment banking, which can split into three main areas:
- Mergers and Acquisitions (M&A): There’s a lot of preparation and paperwork involved whenever corporations merge or make acquisitions. For that reason, this is a crucial service that investment banks provide, and its importance is reflected in the enormous fees recognized. The top five U.S. investment banks collect $10.2 billion in M&A advisory fees, representing 40% of the $25 billion in global M&A fees per year.
- Loan Syndications: Some $16 billion in loan syndication fees are collected annually by investment banks. Loan syndications are when multiple lenders fund one borrower, which can occur when the loan amount is too large or risky for one party to take on. The loan syndication agent is the financial institution involved that acts as the third party to oversee the transaction.
- Capital Markets: Capital markets are financial markets that bring buyers and sellers together to engage in transactions on assets. They split into debt capital markets (DCM) like bonds or fixed income securities and equity capital markets (ECM) (i.e. stocks). Some $41 billion is collected globally for the services associated with structuring and distributing stock and bond offerings.
The top investment banks generally all come from the U.S. and Western Europe, and includes the likes of Goldman Sachs and Credit Suisse.
Sell Side vs Buy Side
Thousands of analysts in corporate finance represent both the buy and sell-sides of the business, but what are the differences between them?
One important difference is in the groups they represent. Buy-side analysts usually work for institutions that buy securities directly, like hedge funds, while sell-side analysts represent institutions that make their money by selling or issuing securities, like investment banks.
According to Wall Street Prep, here’s how the assets of buy-side institutions compare:
|Buy side institution||Total assets|
|Mutual Funds, ETFs||$21 trillion|
|Private equity||$5 trillion|
|Hedge funds||$3 trillion|
|Venture capital||$0.5 trillion|
Also, buy-side jobs appear to be more sought after across financial career forums.
Breaking Down The Buy Side
Mutual funds, ETFs, and hedge funds all generally invest in public markets.
But between them, there are still some differentiating factors. For starters, mutual funds are the largest entity, and have been around since 1924. Hedge funds didn’t come to life until around 1950 and for ETFs, this stretched to the 1990s.
Furthermore, hedge funds are strict in the clients they take on, with a preference for high net worth investors, and they often engage in sophisticated investment strategies like short selling. In contrast, ETFs, and mutual funds are widely available to the public and the vast bulk of them only deploy long strategies, which are those that expect the asset to rise in value.
Private equity (PE) and venture capital (VC) are groups that invest in private companies. Venture capital is technically a form of PE but tends to invest in new startup companies while private equity goes for more stable and mature companies with predictable cash flow patterns.
Who funds the buy side? The source of capital roughly breaks down as follows:
|Source of capital||Capital amount|
|Pension funds||$34 trillion|
|Insurance Companies||$24 trillion|
Endowment funds are foundations that invest the assets of nonprofit institutions like hospitals or universities. The assets are typically accumulated through donations, and withdrawals are made frequently to fund various parts of operations, including critical ones like research.
The largest university endowment belongs to Harvard with some $74 billion in assets under management. However, the largest endowment fund overall belongs to Ensign Peak Advisors. They represent The Church of Jesus Christ of Latter-day Saints (LDS), with some $124 billion in assets.
Primary Market vs Secondary Market
One of the primary motivations for a company to enter the public markets is to raise capital, where a slice of the company’s ownership is sold via an allotment of shares to new investors. The actual capital itself is raised in the primary market, which represents the first and initial transaction.
The secondary market represents transactions after the first. These are considered stocks that are already issued, and shares now fluctuate based on market forces.
Tying It All Together
As the infographic above shows, corporate finance branches out far and wide, handles trillions of dollars, and plays a key part in making modern markets and economies possible.
For those exploring a career in finance, the possibilities and avenues one can take are practically endless.
Visualizing the $94 Trillion World Economy in One Chart
Which countries and regions contribute the most to the world economy? In this infographic, we break down all $94 trillion of global GDP by country.
The $94 Trillion World Economy in One Chart
View the expanded version of this infographic.
Just four countries—the U.S., China, Japan, and Germany—make up over half of the world’s economic output by gross domestic product (GDP) in nominal terms. In fact, the GDP of the U.S. alone is greater than the combined GDP of 170 countries.
How do the different economies of the world compare? In this visualization we look at GDP by country in 2021, using data and estimates from the International Monetary Fund (IMF).
An Overview of GDP
GDP serves as a broad indicator for a country’s economic output. It measures the total market value of final goods and services produced in a country in a specific timeframe, such as a quarter or year. In addition, GDP also takes into consideration the output of services provided by the government, such as money spent on defense, healthcare, or education.
Generally speaking, when GDP is increasing in a country, it is a sign of greater economic activity that benefits workers and businesses (while the reverse is true for a decline).
The World Economy: Top 50 Countries
Who are the biggest contributors to the global economy? Here is the ranking of the 50 largest countries by GDP in 2021:
|Rank||Country||GDP ($T)||% of Global GDP|
|19||🇸🇦 Saudi Arabia||$0.8||0.9%|
|33||🇿🇦 South Africa||$0.4||0.4%|
|40||🇭🇰 Hong Kong SAR||$0.4||0.4%|
|47||🇨🇿 Czech Republic||$0.3||0.3%|
|50||🇳🇿 New Zealand||$0.2||0.3%|
*2020 GDP (latest available) used where IMF estimates for 2021 were unavailable.
At $22.9 trillion, the U.S. GDP accounts for roughly 25% of the global economy, a share that has actually changed significantly over the last 60 years. The finance, insurance, and real estate ($4.7 trillion) industries add the most to the country’s economy, followed by professional and business services ($2.7 trillion) and government ($2.6 trillion).
China’s economy is second in nominal terms, hovering at near $17 trillion in GDP. It remains the largest manufacturer worldwide based on output with extensive production of steel, electronics, and robotics, among others.
The largest economy in Europe is Germany, which exports roughly 20% of the world’s motor vehicles. In 2019, overall trade equaled nearly 90% of the country’s GDP.
The World Economy: 50 Smallest Countries
On the other end of the spectrum are the world’s smallest economies by GDP, primarily developing and island nations.
With a GDP of $70 million, Tuvalu is the smallest economy in the world. Situated between Hawaii and Australia, the largest industry of this volcanic archipelago relies on territorial fishing rights.
In addition, the country earns significant revenue from its “.tv” web domain. Between 2011 and 2019, it earned $5 million annually from companies—including Amazon-owned Twitch to license the Twitch.tv domain name—equivalent to roughly 7% of the country’s GDP.
|🇲🇭 Marshall Islands||Oceania||$0.2|
|🇨🇰 Cook Islands||Oceania||$0.4*|
|🇸🇹 São Tomé and Príncipe||Africa||$0.5|
|🇻🇨 St. Vincent and the Grenadines||Caribbean||$0.8|
|🇰🇳 St. Kitts and Nevis||Caribbean||$1.0|
|🇦🇬 Antigua and Barbuda||Caribbean||$1.4|
|🇸🇧 Solomon Islands||Oceania||$1.7|

Like Tuvalu, many of the world’s smallest economies are in Oceania, including Nauru, Palau, and Kiribati. Additionally, several countries above rely on the tourism industry for over one-third of their employment.
The Fastest Growing Economies in the World in 2021
With 123% projected GDP growth, Libya’s economy is estimated to have the sharpest rise.
Oil is propelling its growth, with 1.2 million barrels being pumped in the country daily. Along with this, exports and a depressed currency are among the primary factors behind its recovery.
2021 Real GDP Growth (Annual % Change)
|2||🇬🇾 Guyana||South America||20.4%|
|7||🇵🇦 Panama||Central America||12.0%|
|8||🇨🇱 Chile||South America||11.0%|
|9||🇵🇪 Peru||South America||10.0%|
|10||🇩🇴 Dominican Republic||Caribbean||9.5%|
Ireland’s economy, with a projected 13% real GDP growth, is being supported by the largest multinational corporations in the world. Facebook, TikTok, Google, Apple, and Pfizer all have their European headquarters in the country, which has a 12.5% corporate tax rate—or about half the global average. But these rates are set to change soon, as Ireland joined the OECD 15% minimum corporate tax rate agreement which was finalized in October 2021.
Macao’s economy bounced back after COVID-19 restrictions began to lift, but more storm clouds are on the horizon for the Chinese district. The CCP’s anti-corruption campaign and recent arrests could signal a more strained relationship between Mainland China and the world’s largest gambling hub.
Looking Ahead at the World’s GDP
The global GDP figure of $94 trillion may seem massive to us today, but such a total might seem much more modest in the future.
In 1970, the world economy was only about $3 trillion in GDP—or 30 times smaller than it is today. Over the next thirty years, the global economy is expected to more or less double again. By 2050, global GDP could total close to $180 trillion.
Correction: In earlier versions of this graphic, countries such as Vietnam and Pakistan were inadvertently not included in the visualization. They have now been added. In cases where the IMF has no data for 2021 (specifically Pakistan, Syria, Afghanistan, and Lebanon), the latest available data is used.
