Why Use Stablecoins: The Problem They Solve In Crypto Markets

One of the main reasons to use stablecoins is that they solve a core problem in crypto: extreme price volatility. By pegging their value to stable assets like the US dollar, they provide a reliable medium of exchange and a safer store of value in an otherwise highly unpredictable ecosystem.

The problem is that most cryptocurrencies like Bitcoin and Ethereum can experience large price swings within short periods of time. This makes everyday transactions, pricing, and risk management difficult for users and businesses. As a result, the crypto market needed a more stable unit of account to function effectively at scale.

What Are Stablecoins?

According to the Bank for International Settlements, stablecoins are digital assets that aim to maintain a stable value by linking themselves to another asset, such as a currency or a basket of assets.

Similarly, the International Monetary Fund explains that stablecoins are designed to bring price stability to blockchain-based payments.

In practice, most widely used stablecoins, such as USDT and USDC, are pegged 1:1 to the US dollar and backed by cash or short-term US Treasury assets.

For example: Circle (issuer of USDC) regularly reports that each USDC is backed by fully reserved dollar-denominated assets, which helps maintain its peg and stability in circulation.

Why Crypto Markets Default To Dollars

The US dollar remains the dominant global currency in trade, finance, and reserves, which naturally extends into digital asset markets. In practice, most cryptocurrencies are quoted against USD or USD-backed stablecoins like USDT and USDC.

For example:

• Instead of pricing Bitcoin in terms of Ethereum (which also fluctuates), exchanges list BTC/USD or BTC/USDT pairs so traders can clearly understand its value at any moment.
• This also simplifies trading decisions. If Bitcoin drops from $100,000 to $85,000, the loss is immediately clear without needing additional conversion.

Why Stablecoins Exist: Volatility In Crypto Markets

According to the International Monetary Fund, the high volatility of cryptocurrencies is a key limitation for their use in payments and as a unit of account.

Price instability reduces the effectiveness of crypto as money, especially when users cannot predict its short-term value. This becomes clearer in real market conditions.

For example:

• In 2022, Bitcoin dropped from around $45,000 in early April to below $20,000 by mid-June - losing more than 50% of its value in just a few months. During major events like the Terra collapse, prices across the market moved rapidly within days.
• In contrast, USD-backed stablecoins like USDT and USDC remained close to $1, allowing traders to exit positions, preserve capital, and re-enter the market without converting back to fiat.

How Stablecoins Solve The Problem

Trading pairs

Stablecoins are essential in trading because they turn a chaotic pricing system into something more understandable. They provide a consistent unit of account, which is critical for liquidity and price discovery.

Without them, traders would have to constantly compare one volatile asset against another, making it difficult to know whether a price move is meaningful or just noise.

For example:

• If Bitcoin is priced in Ethereum, both sides of the pair are moving at the same time, making it hard to interpret the market.
• But when BTC is priced in USDT, traders can clearly see whether its value is actually going up or down in dollar terms.

That is why most trading volume today is concentrated in stablecoin pairs - they simplify decision-making and reduce cognitive friction when navigating fast-moving markets.

Store of value

Stablecoins’ role in crypto markets is as a short-term capital preservation tool, especially in a market where timing matters. In crypto, it’s about avoiding losses during sudden downturns.

According to the International Monetary Fund, stablecoins are widely used during periods of market stress as a way to temporarily store value.

For example: During a sharp sell-off, a trader holding Ethereum can convert to USDC within seconds. This effectively “locks in” their current value, allowing them to wait for clearer market conditions before re-entering.

➡ In this sense, stablecoins function like cash in traditional markets - but with much faster execution.

Settlement layer

Stablecoins also solve a less obvious but critical problem: how value is actually transferred and settled on-chain. In a volatile system, even a small delay between sending and receiving funds can lead to unexpected losses.

Stablecoins improve payment efficiency by removing price uncertainty during settlement. This is especially important in use cases like cross-border transfers, DeFi, and arbitrage trading.

For instance:

• If a user sends $10,000 worth of ETH, the value might change before the transaction is confirmed.
• But if they send $10,000 in USDT, the receiver gets almost exactly that amount.

➡ This predictability is crucial for financial applications, where even small discrepancies can create risk or reduce trust.

Over time, this stablecoins monetary function has positioned them as a core settlement layer for crypto - for exchanges, protocols, and liquidity providers operating across the ecosystem.

USD Vs Bitcoin And Ethereum: The Stability Gap

The key difference between the US dollar and cryptocurrencies like Bitcoin and Ethereum is stability. While the dollar tends to maintain relatively stable purchasing power in the short term, crypto assets can experience large and frequent price swings.

A practical example can be seen in how traders interpret prices.

• When Bitcoin is listed at $110,000, its value is immediately clear.
• But if it is priced at 20 ETH, the meaning is less obvious because Ethereum is also fluctuating.

Another practical example is salary or payments. Very few people are willing to receive a fixed salary in BTC or ETH, because its value could drop before they even spend it. 

Because BTC and ETH cannot reliably serve as a unit of account and medium of exchange, the market naturally defaults back to the dollar for measuring value. That's why crypto needs stablecoins - even in a “crypto-native” environment, users still think in USD terms when making decisions.

➡ Stablecoins exist in between, bringing the stability of USD into crypto so the system can actually function day-to-day. 

Limitations And Risks Of Stablecoins

Stablecoins reduce volatility, but they are not risk-free. Their stability depends on how well they are designed, managed, and regulated, which introduces several important limitations.

Peg risk and depegging events

Stablecoins are only “stable” as long as they can maintain their peg - usually 1:1 with the US dollar. When that mechanism fails, prices can quickly deviate from $1.

According to CoinGecko, several stablecoins have experienced temporary or severe depegging during market stress.

• A well-known example is the Terra collapse, where the algorithmic stablecoin UST lost its peg entirely and fell to near zero.
• Even fiat-backed stablecoins like USDC briefly dropped below $1 during the 2023 banking crisis, showing that peg risk exists across different models.

Centralization risks

Many of the largest stablecoins are issued by centralized entities, which introduces counterparty risk. Users depend on these organizations to manage reserves properly and honor redemptions.

As highlighted by Federal Reserve, centralized stablecoins may also have the ability to freeze or restrict funds under certain conditions.

For example: Issuers like Circle can blacklist specific wallet addresses, meaning users do not have full control over their assets in all situations.

Regulatory uncertainty

Stablecoins operate at the intersection of crypto and traditional finance, which makes them a focus for regulators worldwide. However, rules are still evolving and vary by country.

According to the Financial Stability Board, stablecoins could pose risks to financial stability if widely adopted without proper oversight.

Governments are increasingly introducing new frameworks, but uncertainty remains around how stablecoins will be treated in the long term, especially regarding licensing, reserves, and compliance requirements.

Transparency and reserve concerns

The reliability of fiat-backed stablecoins depends on whether their reserves are fully backed and accessible. If users cannot verify this, trust becomes a key issue.

As noted by Moody's, transparency around reserve composition and regular audits is essential for maintaining confidence in stablecoins.

In the past, some issuers have faced scrutiny over unclear or incomplete disclosures, raising concerns about whether all tokens in circulation are truly backed 1:1.

➡ This means users must trust not only the technology, but also the institutions behind the stablecoin, making transparency a critical factor in long-term adoption.

Conclusion

The real answer to why use stablecoins is because they are stable and they make crypto usable. Without a stable layer, pricing, trading, and transferring value in crypto would be far less practical.

The key insight is this: Stablecoins are not truly “stable” in an absolute sense. Instead of users directly facing volatility like with Bitcoin or Ethereum, the risk moves behind the scenes into issuers, collateral, and regulatory frameworks.

This suggests that the future of crypto will be about how stability is created, managed, and trusted at scale.
