Stablecoin

• 1. Origins And Market Evolution

  ›

  The year 2014 marked the first appearance of stablecoins, a new type of cryptocurrency designed to solve a specific problem for investors. These early digital assets emerged as a method for people holding volatile cryptocurrencies to park their money safely while they waited to buy other assets. The goal was simple: create a digital token that maintained a steady value relative to an asset like the US dollar or gold. By 2025, this experiment had grown into a massive global market worth approximately $255 billion. Nearly 99% of these tokens were pegged directly to the United States dollar. This rapid expansion transformed stablecoins from niche tools into essential infrastructure for modern finance. They now serve as the primary bridge between traditional currency and the volatile world of cryptoassets. Investors use them daily to move funds across borders without waiting days for bank transfers. The scale of adoption suggests that what began as a parking spot for speculative gains has become a permanent fixture in the financial system.

• 2. Classification By Reserve Mechanism

  ›

  Fiat-backed stablecoins claim to hold reserves denominated in government-issued currencies like the US dollar or the euro. Issuers defend the price peg by holding short-term assets such as treasury bonds, commercial paper, and bank deposits. Major examples include Tether's USDT and Circle's USDC, which dominate the market alongside Binance's BUSD. In August 2025, nearly all fiat-backed tokens tracked the value of the American dollar rather than any other currency. Cryptocurrency-backed stablecoins operate differently by using other digital assets as collateral instead of physical money. These tokens rely on smart contracts to track the price of the dollar within decentralized networks. DAI serves as a prominent example of this model, allowing users to convert one cryptocurrency into another standard. Commodity-backed stablecoins exist to mirror the value of physical goods like gold or silver. PAX Gold and Tether Gold allow investors to hold digital claims on actual bullion stored in vaults. Algorithmic stablecoins represent the most fragile category because they lack reserve assets entirely. They use computer algorithms to match supply and demand without holding cash or commodities behind them. The European Central Bank suggests treating these unbacked crypto-assets with extreme caution due to their inherent instability.

• 3. The TerraUSD Collapse Case Study

  ›

  In May 2022, the algorithmic stablecoin known as TerraUSD broke its peg with the United States dollar. Its price plunged to just 10 cents while its linked token LUNA fell to virtually zero from an all-time high of $119.51. This event wiped out almost $45 billion of market capitalization over the course of a single week. Do Kwon founded Terraform Labs to create this system that relied on economic incentives rather than reserves. If TerraUSD traded below $1, arbitrageurs could buy it cheaply and redeem it for $1 worth of LUNA. Conversely, if the price rose above $1, actors could mint new tokens by locking up LUNA. This mechanism assumed sufficient market demand existed for both tokens at all times. When confidence evaporated, the system triggered a death spiral where the supply of LUNA increased exponentially. Validators sold their stakes during the crash, allowing malign actors to become dominant validators in the network. The failure demonstrated how fragile algorithmic designs can be when external liquidity tightens globally. Terraform Labs filed for bankruptcy in January 2024 following the collapse. Do Kwon was extradited to the United States in December 2024 and charged with fraud.

• 4. Global Use Cases And Financial Inclusion

  ›

  Stablecoins facilitate cross-border payments for individuals who lack access to traditional banking systems. A smartphone can send these digital assets instantly, superseding slow correspondent banking networks like SWIFT. People in less developed countries use them to hedge against hyperinflation caused by poor monetary policies. Citizens in Argentina, Turkey, and Venezuela often cannot obtain foreign currencies through formal financial services. They turn to stablecoins as a shield against rapidly depreciating local currencies. Humanitarian NGOs distribute aid in financially repressed regions using these tokens to avoid regulatory holdups. Local communities in Africa have begun accepting stablecoins as payment methods for daily transactions. An International Monetary Fund paper highlighted that Pacific Island nations could benefit from adopting dollar-based stablecoins. These islands lack correspondent banking relationships and retail banks needed for international transfers. Foreign currency-based stablecoins offer the most realistic alternative for countries without national currencies. The technology allows people to participate in global commerce despite limited infrastructure or government support.

• 5. Regulatory Frameworks And Legislation

  ›

  The United States passed the GENIUS Act in July 2025 to allow banks to issue stablecoins backed by high-quality collateral. This legislation aims to generate greater demand for US Treasuries while regulating private issuers. Stephen Miran of the Federal Reserve Board confirmed that stablecoins are already increasing demand for American debt. The European Union introduced the Markets in Crypto-Assets Regulation known as MiCAR in June 2023. It became applicable to asset-referenced tokens on the 30th of June 2024 but lacks clear rules for multi-country redemption scenarios. Hong Kong gazetted its Stablecoins Bill in December 2024 and passed it in May 2025 with licenses expected in early 2026. The Hong Kong Monetary Authority warned the public to rein in euphoria surrounding these new financial tools. Singapore finalized its regulatory framework in November 2023 after a year of public consultation. Issuers must maintain reserve assets denominated in the currency they peg their token to. The Central Bank of Bahrain introduced the SIO Module in July 2025 allowing single currency fiat-backed stablecoins. Japan approved JPYC in August 2025 to launch the first yen-pegged stablecoin in October 2025.

• 6. Financial Risks And Systemic Contagion

  ›

  Reserve-backed stablecoins require third-party custodians to hold assets, creating counterparty risk if those banks fail. In March 2023, Circle's USDC de-pegged temporarily during a banking crisis involving Signature Bank and Silicon Valley Bank. Large redemptions can cause fire sales of underlying assets like treasury bonds, pushing prices down further. This contagion effect mirrors the risks found in money market funds that hold similar portfolios. Money laundering concerns persist because stablecoins enable person-to-person transfers without regulated intermediaries. The Financial Action Task Force issued a report in 2020 highlighting the risk of anonymity facilitating illegal use. Chain-hopping techniques allow criminals to layer transactions across different blockchains to hide trails. Tether's USDT remains the preferred tool for pig butchering scams originating from Southeast Asia. The United Nations Office on Drugs and Crime published a report in January 2024 linking USDT directly to cyberfraud. The US Department of Justice seized $225 million worth of USDT linked to these criminal operations in June 2025. Quantum computing advancements pose a future threat where hackers could break public-key cryptography used by these networks.

• 7. Yield Products And Interest Returns

  ›

  Most stablecoins do not provide interest returns to holders because doing so would classify them as financial securities. The GENIUS Act in the US and MiCAR in Europe explicitly prohibit regulated issuers from offering yield-bearing tokens. Some cryptoasset service providers developed products allowing users to earn interest by re-lending their holdings. Platforms take a margin before passing the remaining interest back to the user. Decentralized platforms offer another avenue through yield farming where liquidity takers pay fees to borrowers. The Anchor protocol created by Terraform Labs offered a yield of 19.5% to depositors of TerraUSD initially. This rate was much higher than the return on US Treasuries at the time. When the price of TerraUSD began to crash, holders were unable to cash out of their positions. They were left holding the bag while the value of their deposits evaporated completely. Singapore restricts such products to institutional investors under limited conditions while the EU bans them entirely. Research suggests that providing interest might reduce the risk of runs on stablecoins but introduces new dangers.
