Some argue that stablecoins are unnecessary due to the ubiquity of the US dollar

Stablecoins could give people in high-inflation economies access to stronger currencies

Specifically, stablecoins could provide a way to make sure these funds remain valuable during times of volatility. Some examples of people without access to the US dollar using stablecoins as a store of value have been observed in Venezuela.

Stablecoins' market cap surged during 2021's crypto bull market

In 2020, the value of all stablecoins was equivalent to just 1% of all physical US dollars. Roughly five years later in August 2025, that value had jumped to roughly 11% of all US cash in circulation.

Learn how stablecoins function in just 4 minutes

This video explains the basics of stablecoins in a beginner-friendly manner. It also dives a bit deeper into the larger stablecoin landscape, detailing, for instance, the many stablecoins backed by fiat currency other than the US dollar, like the euro, the Turkish lira, and the Singapore dollar.

The different types of stablecoins include algorithmic stablecoins

In addition to fiat-backed stablecoins, commodity-backed stablecoins, and cryptocurrency-backed stablecoins, algorithmic stablecoins use smart contract-based mechanisms to maintain a stable value by responding to supply and demand.

Collaterized by crypto, BitUSD is considered the first stablecoin

It was created in 2014 with the intention of making cryptocurrency less volatile. While BitUSD lost its peg to the US dollar in 2018 and never recovered, Tether was created soon after it in 2014 and has had more longevity and success.

The world's largest stablecoins by market cap

The largest stablecoin by market cap, Tether (USDT), as well as the second largest, USDC, are both pegged to the US dollar. As of April 2026, Tether had a roughly $184B market cap.

Stablecoins like USDC are backed by real assets including US Treasurys and cash

While Tether (USDT) is primarily backed by US Treasury bills (64.9%), USDC is mostly backed by US Treasury repurchase agreements (49.6%). USDC also goes by the name Circle, given that it is owned by the company Circle Internet Financial.

Stablecoins now transfer more value than Visa or Mastercard.

Because stablecoins operate on public blockchains, transfers can occur nearly instantly without intermediaries, unlike traditional credit card networks. This has fueled stablecoins' adoption within the crypto world and in cross-border payments. Stablecoin transfer volume rose from about $3B in 2018 to roughly $18T in 2024, overtaking Visa's roughly $16T and Mastercard's $10T.

The first stablecoin pegged to the US dollar launched in 2014

That coin was Tether, also known as USDT. Other key dates in stablecoin history include Circle's launch of USDC in 2018, and, more recently, President Donald Trump's signing of the GENIUS Act in 2025.

The stablecoin market increased tenfold from 2020 to 2025

USDC's reserves were held at Silicon Valley Bank when the bank collapsed

One of the world's largest stablecoin's reserves were held at Silicon Valley Bank, which famously failed in March 2023. USDC briefly lost its peg to the US dollar for a time as a result, within investors pulling out billions of dollars.

The US dollar has served as the world's reserve currency for 80 years—but is its dominance coming to an end?

Since the establishment of the Bretton Woods economic system, about 90% of global foreign exchange transactions have involved USD. Although no viable alternative exists yet, the dollar's share of central bank reserves has decreased from 73% to 58% from 2001 to 2024, and President Trump's 2025 tariffs have sped up this trend.

The US dollar is the official currency of the United States and is the most circulated currency around the world

The US dollar was established in 1792 and comes in the form of coins or paper money. It's considered one of (if not the most) stable currencies in the world due to America’s strong and robust economy, as well as its relatively stable government.

TerraUSD offers a cautionary tale of stablecoin use

This stablecoin was completely wiped out in May 2022, losing investors roughly $40B in value, when its linked support token, LUNA, collapsed in value, triggering a spiral that wiped out the dollar peg and left both tokens essentially worthless within days. TerraUSD's creator was sentenced to 15 years in prison in 2025. (Some users may experience a paywall.)

Arguments for returning to a gold standard reappear from time to time

However, critics argue that globalization has made the gold standard impractical for modern economies, as it limits a nation’s ability to have a flexible monetary policy—hence, none of today's governments have a gold standard.

Fiat money is a currency with no intrinsic, tangible value

Unlike the gold standard, where a nation's currency is linked to the value of gold, fiat money gets its power from the public's trust in its value.

A dollar bill's value relies on two elements: people believing it will be accepted in exchange for goods and services, and how much demand for the currency there is.

British economist John Maynard Keynes originally proposed a global currency called the bancor.

About 17% of US adults said they had invested, traded, or used cryptocurrency in 2023.

Some argue that the $2 bill could be more useful than the $1 bill

Inflation has made purchasing items with just a $1 bill extremely rare. At a time when dollar stores are no longer true to their name, it seems that the $2 note may be the more practical small bill to keep on hand. This article advocates for the use of $2 bills, while detailing their history of being overlooked and the communities that swear by them.

Cryptocurrencies are forms of digital currency

Cryptocurrency's key feature is decentralization. Unlike traditional money, they generally aren't controlled by a single authority. As of early 2025, cryptocurrencies had a cumulative market cap of almost $3.4T, making them worth more than some of the world's most valuable companies, like Google and Amazon (both valued at roughly $2.3T).

The US dollar became the world's reserve currency, backed by gold, after 44 nations gathered in Bretton Woods, New Hampshire, in 1944 with the intention of rebuilding the global economy.

After a series of economic panics induced by a lack of reserve cash at regional banks, the architects of today’s Federal Reserve opted to emphasize the goal of the bank as a reserve at the federal level—thus creating the lasting name.

Many bitcoin enthusiasts have compared the cryptocurrency to digital gold

Gold is valued for its stability and reliability, serving as a hedge against inflation and economic uncertainty. Bitcoin shares both of these characteristics, but also provides near-instant liquidity and isn’t subject to government regulation.

Cryptocurrency acts as a store of value

Traditional money, dating back to its first known uses in ancient Babylonia, has many uses—it reduces friction in transactions by providing a common denominator of value (unit of account), acts as a single item accepted by many vendors (medium of exchange), and holds wealth as a store of value.

The GENIUS Act passed in the US in 2025 was a major milestone for stablecoin regulation

GENIUS stands for the "Guiding and Establishing National Innovation for US Stablecoins." The GENIUS Act defines payment stablecoins as digital money rather than investments and was the first significant piece of stablecoin legislation in the United States.

No institution wields more power in US finance than the Federal Reserve, the central bank of the US—but opinion polls indicate that most Americans don't know what it does.

The US developed a coin circulation problem in 2020

As people reduced the frequency with which they paid for things in cash and change during the COVID-19 pandemic, opting for tap-to-pay systems or online shopping instead, the number of coins in circulation decreased. Those who did make cash purchases were more likely to keep their change at home rather than use it on a subsequent purchase.

Throughout most of the 1800s, US currency was backed by silver and gold

In post-Civil War America, the government moved to use only the gold standard. This was how US currency was backed for decades in the US. You can read a comprehensive explainer on the gold standard and its history in the US to learn more.

Ethereum’s biggest risks and top criticisms

As it evolves, critics say Ethereum’s constant changes make the platform overly complex and fundamentally less secure. They also say the Ethereum Foundation and a handful of developers wield too much control over the crypto platform, and that gas fees are prohibitively expensive. Some criticisms are addressed in Ethereum’s roadmap, but others strike at the crypto platform’s core. Go deeper on why here.

Switzerland's currency is so strong that it could cause deflation

Economic instability in the United States in 2025 strongly benefited Switzerland, where the value of the franc relative to the dollar increased by about 12.7%. In response, the price of imports dramatically decreased, making goods overall much cheaper.

33% of Americans say they don’t know very much about what the Fed does

While most Americans grasp the central bank’s impact on curbing inflation, they don’t know that the Fed is tasked with what is called a “dual mandate” to provide price stability and maximum employment. Furthermore, few understand the Fed is independent—it does not answer to Congress or the US president.

The US has used a wide variety of different currencies between the 1690s and today

From colonial money to national banknotes, people have used all kinds of forms of currency throughout the history of the United States before settling on the dollar bills and quarters that we pay for things with today.

Using cryptocurrency to turn traditional financial arrangements on their head

Cryptocurrency is poised to drastically change everything in the financial world, including financial arrangements. Decentralized finance makes it easier for virtually anyone to take advantage of financial markets without the need for a bank. However, there are new risks involved as well. Professor of Legal Studies and Business Ethics Kevin Werbach, an expert on Bitcoin and blockchains discusses it all in detail in The Conversation.

The Federal Reserve is the most powerful financial institution in the US

The Fed controls the money supply, determines interest rates, and regulates the banking system. Established in 1913 after a volatile series of financial panics, the central bank has managed to retain its legitimacy despite broad critiques against its obscure and independent decision process.

The 10 most important (other) cryptocurrencies

The chief US Treasury economist at the conference, White, advocated for a dollar-centered exchange rate system over Keynes' competing idea of a new global currency, shaping the postwar economic order for decades.

Bitcoin and ethereum are decentralized cryptocurrencies with different functions

Bitcoin, launched in 2009, is primarily a digital currency and store of value with a fixed supply. Ethereum, introduced in 2015, enables smart contracts and decentralized apps, offering more flexibility.

Bitcoin explained and made simple

Bitcoin, the most popular and well-known example of a cryptocurrency, came on the scene around 2010, with its evangelists proclaiming it would eventually displace government-backed traditional cash. While the concept of a digital currency may seem straightforward, the details can be deceptively simple. This quick video overview provides the foundation for a deeper dive into the world of decentralized currency.

Governments have historically used counterfeiting for economic warfare

Inserting fake currency into an economy can help destabilize it. During the American Revolution, for instance, the British distributed counterfeit “Continental Dollars” in an effort to devalue the currency being used in the US at the time with the goal of undermining America’s growing financial credibility. The Nazis also ran an extensive counterfeiting scheme during WWII.

The trillion-dollar coin is a proposed platinum coin with a face value of $1T, which could be used to reduce the national debt

This conceptual strategy was first proposed in 2011 as a potential alternative to raising the US debt ceiling. Although there were several high-profile proponents of the idea, it was eventually rejected in 2013 by Treasury Department and Federal Reserve officials.
