The world's largest stablecoins by market cap

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.

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' market cap surged during 2021's crypto bull market

Collaterized by crypto, BitUSD is considered the first stablecoin

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

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

Others have criticized fiat-backed stablecoins for their lack of decentralization, believing that digital currencies not controlled by central banks will become more popular in the future.

The US dollar is the most widely circulated currency in the world, and is involved in nearly 90% of global transactions

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.

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.)

Cryptocurrencies are forms of digital currency
