Acceptable Media of Exchange: Stablecoins

In the rapidly evolving landscape of digital finance, stablecoins have emerged as a critical component of the tokenized economy. While traditional cryptocurrencies like Bitcoin and Ethereum are known for their volatility, stablecoins provide a much-needed anchor of stability. By pegging their value to a stable asset, usually a fiat currency, stablecoins enable seamless transactions, enhance liquidity, and offer a reliable store of value within blockchain ecosystems. Here, we explore the definition, types, and regulatory considerations of stablecoins, as well as their growing importance in the world of tokenization.

Stablecoins being Settlement Tokens

Stablecoins are digital currencies designed to minimize price volatility by pegging their value to a stable reference asset. This can be a fiat currency like the US dollar, a basket of assets, or even other cryptocurrencies. The primary goal of stablecoins is to combine the benefits of blockchain technology — such as transparency, security, and low transaction costs — with the stability of traditional financial assets. By providing a stable medium of exchange, stablecoins can serve a variety of functions within the broader tokenized economy.

Stablecoins play a pivotal role in the tokenized economy, acting as a bridge between volatile cryptocurrencies and the stable world of traditional finance. They serve multiple purposes that are essential for the smooth functioning of tokenized markets.

As a medium of exchange, stablecoins facilitate transactions across blockchain ecosystems by offering a reliable means of valuing and trading tokenized assets. Their stable value mitigates the risk of price volatility common with other cryptocurrencies, making them ideal for everyday use and large-scale trades.

They also serve as a store of value, offering a safe alternative to volatile cryptocurrencies like Bitcoin or Ethereum. By maintaining a consistent value, often pegged to fiat currencies, stablecoins allow users to preserve capital and avoid sudden depreciation, which is especially important in tokenized asset markets.

Acting as a unit of account, stablecoins provide a consistent pricing standard for goods, services, and assets within tokenized ecosystems. This stability ensures that prices remain understandable and predictable, fostering trust and usability.

Stablecoins are a key gateway to decentralized finance (DeFi), enabling users to engage in lending, borrowing, and other financial activities with tokenized assets. Their stability and liquidity are crucial for supporting DeFi platforms and bridging traditional finance with decentralized systems.

Types of Stablecoins and Their Regulatory Status

Stablecoins come in various forms depending on the mechanism used to maintain their value. There are three main types of stablecoins — fiat-collateralized, crypto-collateralized, and algorithmic stablecoins — each with its own strengths, risks, and regulatory considerations.

Fiat-Collateralized Stablecoins

Fiat-collateralized stablecoins are backed by a reserve of fiat currency, typically held in a bank account. These stablecoins maintain a 1:1 peg to a fiat currency, such as the US dollar (USD) or the Euro (EUR), ensuring that each stablecoin is fully redeemable for its corresponding fiat value. This type of stablecoin is among the most widely adopted due to its simplicity and trustworthiness.

Users deposit fiat currency with a trusted entity, which then issues an equivalent amount of stablecoins. This reserve of fiat currency ensures that the stablecoins can be redeemed at any time, providing a high level of trust and liquidity. Typical examples include Tether (USDT), USD Coin (USDC)

Fiat-collateralized stablecoins may be subject to financial regulations similar to those governing traditional financial institutions. However, regulatory frameworks vary by jurisdiction. Some countries impose strict guidelines that ensure transparency and regular audits of the fiat reserves backing these stablecoins, fostering trust and encouraging wider adoption.

Crypto-Collateralized Stablecoins

Crypto-collateralized stablecoins are backed by reserves of other cryptocurrencies rather than fiat currency. To account for the volatility of cryptocurrencies, they are often over-collateralized, meaning that the value of the collateral exceeds the stablecoin’s value. This decentralized approach maintains stability without relying on traditional financial systems.

Users lock up cryptocurrency as collateral in a smart contract, which then issues stablecoins based on the value of the collateral. In the event of significant price fluctuations, automated liquidation mechanisms help maintain the stablecoin’s value, Dai (DAI) from MakerDAO is a typical example. This ensures that the value of the stablecoin remains stable, even in the face of significant market movements, thus supporting the integrity of tokenized asset transactions.

Crypto-collateralized stablecoins face unique regulatory challenges because they operate within decentralized frameworks. Regulators are primarily concerned with ensuring that these stablecoins maintain sufficient collateral reserves and operate transparently.

Algorithmic Stablecoins

Algorithmic stablecoins use algorithms and smart contracts to manage the supply of the stablecoin, aiming to keep its value stable without direct backing by fiat or crypto assets. Instead of being collateralized, these stablecoins rely on market demand and supply adjustments to maintain their peg.

Algorithms automatically expand or contract the supply of the stablecoin in response to price fluctuations, similar to how central banks manage the supply of fiat currency. This mechanism is designed to keep the stablecoin’s value close to its target peg.

Algorithmic stablecoins introduce innovative methods for maintaining stability in the tokenized economy. However, they also carry higher risks, as their stability is not guaranteed by tangible assets. The collapse of TerraUSD (UST) in May 2022 highlights the risks inherent to algorithmic stablecoins. Without a solid foundation of collateral, these stablecoins can experience rapid devaluation, which can cause significant disruptions in tokenized markets.

Recognizing the complications and risks associated with algorithmic stablecoins, they undoubtedly require more sophisticated regulatory standards and scrutiny. However, the current regulatory frameworks in Singapore and Hong Kong do not deem algorithmic stablecoins as acceptable options.

Stablecoins in Blockchain Settlements

The core advantage of stablecoins in blockchain settlements lies in their price stability and liquidity. The mechanisms by which stablecoins facilitate trading, especially across different blockchain networks, however, are more complex and involve considerations like cross-chain compatibility, bridging solutions, and interoperability.

Stablecoins maintain their value through a mechanism that pegs them to a stable asset or fiat currency. By offering a stable and widely accepted medium for converting various tokens, they allow users to quickly swap between different assets without needing to exit the blockchain environment.

However, a challenge arises when the traded tokens and the stablecoins used for settlement exist on different blockchains. For example, a user may hold Ethereum (ETH) on the Ethereum blockchain, but the stablecoin they wish to use for settlement, such as USDC, may be on the Polygon network.

This is where cross-chain bridges and interoperability solutions come into play. Cross-chain bridges enable the transfer of assets between blockchains by locking tokens on the source chain and minting equivalent tokens on the destination chain. For instance, if a trader holds USDC on Ethereum but wants to settle a transaction on the Binance Smart Chain (BSC), a bridge can lock the USDC on Ethereum and issue an equivalent amount of BSC-compatible USDC on Binance Smart Chain. This ensures that transactions can occur seamlessly, even when the assets involved reside on different networks.

Cross-Chain Mechanisms

The ability of stablecoins to operate across multiple blockchains is critical for facilitating the trading of other tokens that may reside on different chains. The most widely used stablecoins, such as USDT and USDC, are multi-chain — meaning they exist on multiple blockchain networks, including Ethereum, BSC, Polygon, Solana, and others. This multi-chain functionality is crucial for enabling cross-chain transactions. When trading tokens on different chains, the following mechanisms are usually employed:

Native Stablecoin Transfers: If the stablecoin exists natively on both blockchains, the user can transfer the stablecoin across chains using a cross-chain bridge. For example, a trader wishing to use USDC to settle a transaction on Solana but holding USDC on Ethereum can use a bridge to transfer USDC from Ethereum to Solana. The bridge will lock the Ethereum-based USDC in a smart contract and issue an equivalent amount of Solana-based USDC on the Solana blockchain. This allows the user to settle the transaction on Solana without needing to convert the stablecoin into another asset.

Wrapped Tokens: In some cases, a stablecoin on one blockchain is wrapped to represent its value on another chain. For instance, Wrapped USDC (wUSDC) can be used on blockchains where the native USDC token is not directly available. Wrapped tokens are essentially representations of the original token, backed 1:1 by the actual token locked on the original chain. This method ensures that even if the stablecoin does not natively exist on a particular blockchain, its value can still be transferred and used for settlement purposes.

Liquidity Pools and Decentralized Exchanges (DEXs): On DeFi platforms, stablecoins often act as a bridge between different tokens through liquidity pools on decentralized exchanges (DEXs). For example, a user holding Binance Coin (BNB) on BSC but needing DAI on Ethereum can swap BNB for USDT on BSC, then use a cross-chain bridge to transfer USDT to Ethereum, and finally swap USDT for DAI on an Ethereum-based DEX. This process leverages the widespread availability of stablecoins across multiple liquidity pools to facilitate trading across different chains.

Smart Contracts and Automation

Stablecoins also enhance transaction efficiency through integration with smart contracts. Smart contracts can automate settlement processes by executing predefined conditions, such as releasing payment once a specific token or asset has been transferred. This capability is especially useful for decentralized applications (dApps) and complex financial products that require precise and timely execution, such as option contracts, token swaps, and real estate transactions.

For example, in a tokenized real estate transaction, a smart contract could be programmed to automatically release payment in USDC to the seller once the property’s ownership has been transferred on-chain to the buyer. This not only reduces the need for intermediaries but also ensures that settlements occur instantly, with minimal room for disputes or delays.

Cost-Effectiveness and Speed

One of the most significant advantages of using stablecoins as settlement tokens is their cost-effectiveness. Transactions involving stablecoins typically incur lower fees than traditional financial systems, especially for cross-border transactions. For example, international bank transfers can take several days and incur high fees due to currency conversion and intermediary banks. In contrast, stablecoin transfers can be completed in minutes, with minimal transaction fees, even if they traverse multiple blockchains. This speed and reduced cost make stablecoins an attractive option for businesses engaged in global trade.

Moreover, stablecoins reduce the need for businesses to convert cryptocurrencies back into fiat currencies, which can be both time-consuming and costly. Instead, businesses can hold stablecoins in their wallets and use them for instant, low-cost payments to suppliers, employees, and contractors across the globe.

Comparison with CBDC Programmable Tokens

While stablecoins offer substantial benefits in blockchain transactions, Central Bank Digital Currencies (CBDCs) represent another form of digital currency that could play a similar role in the future. CBDCs are digital versions of fiat currencies issued and regulated by central banks and may offer some advantages over privately issued stablecoins.

Regulation and Trust

One of the primary differences between stablecoins and CBDCs is the level of regulation and trust. CBDCs are backed by central governments and subject to comprehensive regulatory frameworks, which can provide users with a higher degree of security and trust compared to stablecoins that are issued by private entities. For example, a digital dollar issued by the Federal Reserve would carry the full backing of the U.S. government, making it a trusted medium for on-chain transactions in both traditional and decentralized finance environments.

Programmability and Interoperability

CBDCs also offer greater programmability than most stablecoins. Central banks could design CBDCs with built-in features that allow for automated compliance with regulatory requirements, conditional payments, and more complex financial interactions. For instance, a CBDC could be programmed to automatically enforce tax withholding during a transaction or limit its use to specific types of purchases, adding a layer of functionality that is not typically available with stablecoins.

Additionally, CBDCs are likely to be highly interoperable with existing financial systems, potentially allowing for seamless integration with traditional banking services. This could make CBDCs more attractive for businesses and consumers who need to move funds between blockchain networks and the fiat-based financial system. In contrast, stablecoins primarily operate within the crypto ecosystem, which may limit their interoperability with traditional financial institutions.

Upcoming Regulated Stablecoins

United Kingdom (UK): The UK is developing a stablecoin framework under the Financial Services and Markets Act (FSMA), which will regulate the issuance of stablecoins and enhance market trust.
European Union (EU): The EU’s Markets in Crypto-Assets Regulation (MiCA) is expected to introduce new standards for stablecoins, providing a secure and regulated medium for tokenized transactions across Europe.
Singapore (SG): The Monetary Authority of Singapore (MAS) has issued guidelines for stablecoins, aiming to support the city-state’s position as a global fintech hub.
Hong Kong (HK): The Hong Kong Monetary Authority (HKMA) is developing a regulatory regime for stablecoins, which is expected to enhance the local and regional tokenized asset markets.

What’s Next

Stablecoins are playing an increasingly important role in the tokenized economy by providing stability, liquidity, and a bridge to traditional financial systems. Whether used as a medium of exchange, store of value, or unit of account, stablecoins are essential for mitigating the volatility of the cryptocurrency market and facilitating the growth of tokenized assets. By understanding the different types of stablecoins and their regulatory frameworks, participants in the tokenized economy can better leverage these assets to enhance trust, stability, and efficiency in their transactions. Next, we will look into other tokenized assets and current adoption.
