Stablecoins are cryptocurrencies designed to maintain a stable value, typically pegged 1:1 to the US dollar. Unlike Bitcoin or Ethereum, which can swing 10% or more in a single day, stablecoins aim to stay within fractions of a cent of their target price. The global stablecoin market now exceeds $255 billion in total value (BIS, June 2025), with nearly 99% of all stablecoins pegged to the US dollar.
Whether you're trading crypto, sending money internationally, or earning yield on your holdings, stablecoins have become essential infrastructure for the digital asset economy. This guide covers everything you need to know: how stablecoins work, the different types, which ones are safest, current interest rates, and what regulations mean for the future.
How Do Stablecoins Work?
Stablecoins maintain their $1 value through backing mechanisms: fiat reserves (cash and Treasury bonds held by the issuer), cryptocurrency collateral (over-collateralized crypto locked in smart contracts), or algorithms (code that automatically adjusts supply to match demand). Each mechanism carries different risk profiles and trade-offs between decentralization, stability, and capital efficiency.
When you buy a stablecoin like USDC, the issuer (Circle) is supposed to hold one dollar in reserve for every USDC token in circulation. When demand increases, the issuer mints new tokens and deposits more reserves. When users redeem their stablecoins for dollars, the issuer burns the tokens and releases reserves. This mint-and-burn mechanism keeps supply matched to demand.
The key difference from traditional banking: stablecoin transactions settle on blockchain networks in seconds or minutes, operate 24/7, and don't require bank intermediaries. A $10 million USDC transfer settles just as fast as a $10 transfer—something impossible with traditional wire systems.
What Makes Stablecoins Different from Bitcoin?
Bitcoin and stablecoins serve fundamentally different purposes. Bitcoin is a volatile store of value with fixed supply; stablecoins are stable payment instruments with flexible supply.
| Factor | Bitcoin | Stablecoins |
|---|---|---|
| Price volatility | ±5-10% daily swings common | <0.5% deviation typical |
| Backing | None (value from scarcity and demand) | Reserves or algorithms |
| Primary use case | Store of value, speculation | Payments, trading, yield |
| Supply mechanism | Fixed (21M cap, halving schedule) | Flexible (minted and burned on demand) |
| Settlement time | 10+ minutes (varies by congestion) | Seconds to minutes (chain-dependent) |
| Value proposition | Appreciation potential | Stability and utility |
Bitcoin can move 15% in a day during market events. Stablecoins typically stay within 0.1% of their peg during normal conditions. This stability makes stablecoins useful for trading, payments, and as a parking spot for capital—while Bitcoin serves as a long-term investment thesis.
What Are the Different Types of Stablecoins?
There are four main types of stablecoins: fiat-backed (USDT, USDC), crypto-backed (DAI), commodity-backed (Tether Gold, PAX Gold), and algorithmic (USDD, Celo Dollar). Fiat-backed stablecoins dominate the market with over 95% share. Each type uses different backing mechanisms, carries different risks, and receives different regulatory treatment.
Fiat-Backed Stablecoins
Fiat-backed stablecoins are issued by centralized companies that hold dollar-denominated reserves—typically cash, bank deposits, and US Treasury bonds—to back each token 1:1.
How they work: When you deposit $100 with Circle, they mint 100 USDC tokens and add $100 to their reserve accounts. When you redeem USDC for dollars, Circle burns the tokens and sends you cash. Examples: - USDT (Tether): $145+ billion market cap, largest stablecoin - USDC (Circle): $73+ billion market cap, considered most transparent - FDUSD (First Digital): $4.8 billion, popular on Binance - TUSD (TrueUSD): $1.9 billion, regulatory challenges Advantages: High liquidity, wide acceptance, regulatory clarity (in compliant jurisdictions). Risks: Counterparty risk (issuer could mismanage reserves), custodian risk (banks holding reserves could fail), regulatory risk (governments could restrict operations).Crypto-Backed Stablecoins
Crypto-backed stablecoins use cryptocurrency as collateral instead of dollars. Because crypto is volatile, these systems require over-collateralization—typically $1.50 or more in crypto locked for every $1 of stablecoins issued.
How they work: To mint DAI, you deposit ETH or other approved crypto into a smart contract (called a Vault or CDP). You can then borrow DAI against that collateral. If your collateral value drops below the required ratio, your position gets liquidated automatically. Examples: - DAI (MakerDAO): $5.4 billion market cap, largest decentralized stablecoin - sUSD (Synthetix): Backed by SNX tokens - LUSD (Liquity): ETH-backed, immutable smart contracts Advantages: Decentralized (no single issuer to trust), transparent (reserves verifiable on-chain), censorship-resistant. Risks: Liquidation risk during market crashes, smart contract vulnerabilities, complexity for average users.Commodity-Backed Stablecoins
Commodity-backed stablecoins are pegged to physical assets like gold, oil, or real estate rather than fiat currency.
How they work: Each token represents ownership of a specific amount of the underlying commodity. Tether Gold (XAUT) and Paxos Gold (PAXG) each represent one troy ounce of gold stored in vaults. Examples: - PAXG (Pax Gold): Each token backed by one ounce of London Good Delivery gold - XAUT (Tether Gold): Gold stored in Swiss vaults - Redeemable: PAXG can be redeemed for physical gold (minimum 430 oz) Advantages: Exposure to commodities without storage hassles, easy transfer of ownership, potential inflation hedge. Risks: Price tracks commodity (not stable in dollar terms), storage and insurance costs, custodian risk.Algorithmic Stablecoins
Algorithmic stablecoins attempt to maintain their peg through code rather than collateral. They use supply-and-demand mechanisms to expand and contract token supply automatically.
/blog/algorithmic-stablecoins
How they work: When the stablecoin trades above $1, the algorithm mints new tokens to increase supply and push the price down. When it trades below $1, the algorithm reduces supply (often by incentivizing users to burn tokens in exchange for another asset). The problem: Algorithmic stablecoins are vulnerable to "death spirals" where loss of confidence triggers mass selling, which triggers more supply reduction, which fails to restore the peg, which causes more selling. The TerraUSD (UST) collapse: In May 2022, TerraUSD—then the third-largest stablecoin with $18 billion market cap—crashed from $1 to $0.10 in days. The collapse wiped out approximately $45 billion in value across UST and its sister token LUNA. Current examples: USDD, Celo Dollar, FRAX (partial algorithmic). Risk level: High. Most experts recommend avoiding purely algorithmic stablecoins.Comparison Table: Types of Stablecoins
| Type | Backing Mechanism | Decentralized? | Risk Level | Capital Efficiency | Examples |
|---|---|---|---|---|---|
| Fiat-backed | Cash, T-bills, bank deposits | No | Low-Medium | High (1:1) | USDT, USDC, FDUSD |
| Crypto-backed | ETH, BTC, other crypto | Yes | Medium | Low (150%+ collateral) | DAI, sUSD, LUSD |
| Commodity-backed | Gold, oil, real estate | No | Medium | High (1:1) | PAXG, XAUT |
| Algorithmic | None (code-based) | Yes | High | Very High (0% collateral) | USDD, FRAX |
What Are the Largest Stablecoins by Market Cap?
Tether (USDT) is the largest stablecoin with over $145 billion market cap and approximately 59% market dominance. USDC ranks second at $73 billion (29% share). DAI is the largest decentralized stablecoin at $5.4 billion. Together, the top 10 stablecoins represent over 98% of total stablecoin market value.
The stablecoin market has grown from under $5 billion in early 2020 to over $255 billion by mid-2025—a 50x increase in five years. This growth reflects broader crypto adoption and stablecoins' utility for trading, DeFi, and international payments.

Are Stablecoins Safe?
Stablecoins are safer than volatile cryptocurrencies but carry unique risks including depegging (losing the $1 peg), reserve opacity (unclear what's backing them), regulatory uncertainty, and issuer counterparty risk. The TerraUSD collapse in 2022 and USDC's temporary depeg during the SVB crisis prove stablecoins aren't risk-free.
/blog/are-stablecoins-safe
No stablecoin offers the same protections as FDIC-insured bank deposits. When you hold stablecoins, you're trusting the issuer's reserve management, their banking partners, the smart contracts involved, and the regulatory environment—none of which come with government guarantees.
What Are the Main Risks of Stablecoins?
| Risk Type | Description | Real-World Example |
|---|---|---|
| Depegging | Price falls significantly below $1 peg | UST crashed from $1 to $0.10 (May 2022) |
| Reserve risk | Insufficient or illiquid backing assets | Tether maintained full reserves during only 27.6% of the days examined (2016-2018 CFTC finding) |
| Counterparty risk | Banks or custodians holding reserves fail | USDC depegged to $0.87 when SVB collapsed (March 2023) |
| Regulatory risk | Government restricts or bans operations | BUSD ordered to stop minting by NYDFS (Feb 2023) |
| Smart contract risk | Code vulnerabilities enable exploits | Various DeFi hacks affecting stablecoin protocols |
| Concentration risk | Heavy reliance on single banks/custodians | Circle held $3.3B at Silicon Valley Bank |
How to Evaluate Stablecoin Safety
Before holding significant value in any stablecoin, assess these factors:
Reserve transparency checklist: - Regular third-party audits or attestations (monthly preferred) - Transparent reserve composition disclosure (% cash, T-bills, etc.) - Licensed in major jurisdictions (US, EU) - Strong peg stability history (<0.5% deviation from $1) - Reputable attestation provider (Big 4 accounting firm preferred) - Clear redemption mechanism for institutional holdersReserve Transparency Grades
| Stablecoin | Grade | Audit Frequency | Attestor | Reserve Disclosure |
|---|---|---|---|---|
| USDC | A | Monthly | Deloitte | Full breakdown published |
| USDT | B- | Quarterly | BDO Italia | Summary only, no full audit |
| DAI | B+ | Real-time | On-chain verifiable | 100% transparent |
| FDUSD | B | Monthly | Third-party | Published reserves |
| TUSD | C | Irregular | The Network Firm | Limited disclosure |
Grades reflect Bitcompare's assessment of reserve transparency, audit quality, and regulatory compliance.
What Is Stablecoin Depegging?
Depegging occurs when a stablecoin's market price falls significantly below its intended $1 value. This happens due to bank runs on reserves, algorithmic failures, loss of market confidence, or external shocks like banking crises. The most severe depegging event was TerraUSD (UST) in May 2022, which crashed from $1 to $0.10, erasing approximately $45 billion in value.
/blog/stablecoin-depegging
Major Depegging Events
TerraUSD (UST) — May 2022: - Crashed from $1 to $0.10 over several days - Algorithmic mechanism failed during sell pressure - $45 billion market cap destroyed - Triggered broader crypto market crash - Luna Foundation Guard's $2.4B Bitcoin reserve (80,394 BTC) couldn't save the peg USDC — March 2023: - Briefly dropped to $0.87 during Silicon Valley Bank collapse - Circle had $3.3 billion in reserves at SVB - Peg fully recovered within four days after Fed backstop announcement - Demonstrated even "safe" stablecoins face banking system risk TUSD — June 2025: - Brief depeg to $0.985 amid redemption concerns - Questions about reserve attestation practices - Recovered but highlighted ongoing transparency issuesPeg Stability Scores
Bitcompare tracks peg stability using a proprietary scoring system based on 90-day weighted average deviation from the $1 peg.
| Stablecoin | Peg Stability Score | Grade | Max Deviation (90d) |
|---|---|---|---|
| USDC | 99.2 | A+ | 0.3% |
| USDT | 98.7 | A+ | 0.5% |
| DAI | 96.4 | A | 1.2% |
| FDUSD | 97.8 | A | 0.8% |
| TUSD | 94.2 | B+ | 1.8% |
Scores range 0-100. Higher scores indicate tighter peg maintenance.
How Are Stablecoins Regulated?
Stablecoin regulation varies significantly by jurisdiction. The United States passed the GENIUS Act in July 2025, establishing a federal framework that allows banks to issue stablecoins backed by US Treasuries. The European Union's MiCA regulation took effect for stablecoins in June 2024. Hong Kong passed its Stablecoin Bill in 2024. Most frameworks require 1:1 reserves and prohibit issuers from offering yield-bearing stablecoins directly.
/blog/stablecoin-regulation
Key Regulatory Frameworks
United States — GENIUS Act (July 2025): - Federal licensing pathway for stablecoin issuers - Requires 1:1 reserve backing (cash, T-bills, Fed deposits) - Prohibits issuer-paid yield (interest must come from third parties) - Bank holding companies can issue stablecoins - State-licensed issuers remain valid under $10B threshold European Union — MiCA (June 2024): - E-money token (EMT) classification for single-currency stablecoins - Strict reserve requirements (30% cash at EU banks) - Transaction volume caps for non-EUR stablecoins - USDT currently non-compliant; USDC compliant - Significant issuer licensing requirements Hong Kong — Stablecoin Bill (2024): - Licensing regime through Hong Kong Monetary Authority - Reserve backing requirements - Consumer protection provisions - Positioned as Asia-Pacific stablecoin hubRegulatory Status by Jurisdiction
| Stablecoin | US (GENIUS) | EU (MiCA) | UK | Singapore | Hong Kong |
|---|---|---|---|---|---|
| USDC | Compliant | Compliant | Under review | MAS approved | Pending |
| USDT | Varies by state | Non-compliant | Under review | MAS approved | Pending |
| DAI | Uncertain | Unclear (decentralized) | TBD | TBD | TBD |
| FDUSD | Limited presence | Pending | N/A | TBD | HK-based |
What Is Tether (USDT)?
Tether (USDT) is the world's largest stablecoin with over $145 billion market cap and 59% market dominance. Launched in 2014, USDT is issued by Tether Limited (a subsidiary of iFinex, which also owns Bitfinex exchange). Tether claims backing by cash, cash equivalents, and other reserves. USDT operates on multiple blockchains including Ethereum, Tron, Solana, and Arbitrum.
/blog/tether-usdt
Key Facts About Tether
- Market cap: $145+ billion (largest stablecoin)
- Daily trading volume: $52+ billion (most liquid stablecoin)
- Launch date: 2014 (first major stablecoin)
- Primary networks: Tron (28% of supply), Ethereum, Solana
- Reserve attestor: BDO Italia (quarterly attestations)
Tether Controversies
Reserve transparency concerns: - Never completed a full independent audit by a major accounting firm - 2021 CFTC investigation found Tether maintained full reserves during only 27.6% of the days examined in 2016-2018 - $41 million fine paid to CFTC for "untrue or misleading statements" about reserves - Current attestations show improved reserves but still lack full audit detail Why it still dominates: Despite controversies, USDT maintains market leadership due to first-mover advantage, deep liquidity on exchanges, and widespread adoption—particularly in Asia and on Tron network. Many traders accept the trade-off between transparency concerns and USDT's unmatched liquidity.Can You Earn Interest on Stablecoins?
Yes, you can earn 4-10% APY on stablecoins through lending platforms, DeFi protocols, and liquidity provision. Centralized platforms like Nexo and YouHodler offer up to 8% on USDT. Decentralized protocols like Aave and Compound provide variable rates around 4-6%. Note: earning yield adds counterparty risk (centralized platforms) or smart contract risk (DeFi protocols).
Best Stablecoin Interest Rates
| Stablecoin | Platform | Platform Type | APY | Term | Risk Level |
|---|---|---|---|---|---|
| USDT | Nexo | CeFi Lending | 8.00% | Flexible | Medium |
| USDT | YouHodler | CeFi Lending | 7.50% | Flexible | Medium |
| USDC | Aave v3 | DeFi | 5.20% | Flexible | Medium |
| USDC | Compound v3 | DeFi | 4.80% | Flexible | Medium |
| DAI | Spark (DSR) | DeFi Savings | 5.00% | Flexible | Low-Medium |
| USDC | Coinbase | Exchange | 4.00% | Flexible | Low |
Rates as of February 2026. APY fluctuates based on market conditions.
Important Yield Considerations
Regulatory restrictions: The US GENIUS Act, EU MiCA, and Hong Kong Stablecoin Bill all prohibit licensed stablecoin issuers from paying yield directly on their tokens. Any interest you earn comes from third-party platforms—not from Circle or Tether themselves. Risk-return trade-off: Higher yields typically mean higher risk. An 8% APY on a centralized lending platform means you're trusting that platform's creditworthiness, security practices, and business model. Several crypto lending platforms (Celsius, BlockFi, Voyager) collapsed in 2022, causing billions in customer losses. Where yield comes from: - Lending platforms earn by lending your stablecoins to borrowers at higher rates - DeFi protocols facilitate peer-to-peer lending through smart contracts - Stablecoin issuers earn yield on reserves (5%+ on T-bills) but keep it as profitWhat Are Stablecoins Used For?
Stablecoins serve three primary use cases: trading cryptocurrency (parking value between volatile positions), cross-border payments (faster and cheaper than SWIFT wire transfers), and hedging against local currency inflation (maintaining dollar value in countries with unstable currencies like Argentina, Turkey, and Venezuela).
Trading and Investing
Stablecoins are the backbone of cryptocurrency trading:
- Base pair liquidity: Most crypto exchanges use stablecoins (particularly USDT) as primary trading pairs
- Volatility parking: Traders move to stablecoins to avoid drawdowns without converting to fiat
- 24/7 availability: Unlike fiat, stablecoins trade around the clock
- Faster settlement: Move between exchanges in minutes rather than days
Cross-Border Payments
Traditional international wire transfers take 3-5 business days and cost $25-50 in fees. Stablecoin transfers settle in minutes and cost under $1 on efficient networks.
Use cases: - Remittances to family in other countries - International contractor and freelancer payments - B2B cross-border settlements - Avoiding currency conversion feesInflation Hedge
In countries with high inflation or unstable currencies, stablecoins provide access to dollar-denominated value:
- Argentina: Peso saw 289% year-on-year inflation by April 2024; citizens use stablecoins to preserve savings
- Turkey: Lira depreciation drives stablecoin adoption
- Venezuela: Hyperinflation makes stablecoins essential for commerce
- Accessibility: Anyone with a smartphone can hold dollars via stablecoins—no bank account required
DeFi and Yield Generation
Stablecoins power decentralized finance (DeFi):
- Liquidity provision: Supply stablecoins to decentralized exchanges (Uniswap, Curve) and earn trading fees
- Lending protocols: Lend through Aave, Compound, or Spark to earn interest
- Collateral: Use stablecoins as collateral for crypto loans
- Yield farming: More complex strategies combining multiple DeFi protocols
How Do I Buy Stablecoins?
You can buy stablecoins on major cryptocurrency exchanges like Coinbase, Kraken, or Binance using bank transfer, credit card, or other cryptocurrencies. Create an account, complete identity verification (KYC), deposit funds, and purchase USDC, USDT, or other stablecoins. Tokens can remain in your exchange wallet or transfer to a personal crypto wallet for self-custody.
Step-by-Step Process
- Choose an exchange: Select a reputable exchange available in your jurisdiction (Coinbase, Kraken, Gemini for US; Binance for international)
- Create and verify account: Sign up and complete Know Your Customer (KYC) verification with government ID and proof of address
- Deposit funds: Connect bank account for ACH transfer (lowest fees), or use debit card/wire transfer for faster funding
- Buy stablecoins: Navigate to the trading section, select your stablecoin (USDC, USDT), enter amount, and execute purchase
- Store securely: Keep on exchange for convenience and trading, or withdraw to personal wallet (hardware wallet like Ledger for large amounts) for self-custody
Choosing Between USDT and USDC
For most users, USDC offers the better risk profile due to superior transparency and regulatory compliance. Choose USDT if you need maximum liquidity or primarily trade on exchanges where USDT pairs dominate.
Stablecoins vs CBDC: What's the Difference?
Stablecoins are issued by private companies (like Tether or Circle), while CBDCs (Central Bank Digital Currencies) are issued directly by governments. In monetary terms, stablecoins represent M2 money supply (commercial bank money), while CBDCs would be M0 (monetary base, like physical cash). China's digital yuan is a live CBDC; the European digital euro remains in development.
Comparison: Stablecoins vs CBDCs
| Factor | Stablecoins | CBDCs |
|---|---|---|
| Issuer | Private companies (Circle, Tether) | Central banks (Fed, ECB, PBOC) |
| Money type | M2 (commercial deposits) | M0 (base money, like cash) |
| Live examples | USDT, USDC, DAI | Digital yuan (China), e-CNY |
| Development status | Mature, $255B+ market | Limited pilots, mostly development |
| Privacy level | Pseudonymous (address-based) | Government-tracked (varies by design) |
| Innovation speed | Fast (market-driven) | Slow (regulatory process) |
| Interoperability | Multi-chain, global | Jurisdiction-specific |
| Yield potential | Yes (third-party) | Typically no (policy tool) |
Why CBDCs Matter for Stablecoins
Central banks developing CBDCs could eventually compete with or restrict private stablecoins. China's digital yuan is already live with millions of users. The European Central Bank is developing a digital euro. The Federal Reserve is studying a potential digital dollar.
However, CBDCs face adoption challenges (privacy concerns, limited innovation) that stablecoins don't. Most experts expect stablecoins and CBDCs to coexist, serving different use cases.
Frequently Asked Questions
What is the safest stablecoin?
USDC is widely considered the safest major stablecoin due to monthly audits by Deloitte, full reserve transparency, and regulatory compliance in both the US (GENIUS Act) and EU (MiCA). Circle holds reserves in cash and short-term US Treasury bonds with regulated custodians. That said, no stablecoin offers FDIC insurance—all carry some risk.
Can stablecoins lose value?
Yes. Stablecoins can "depeg" and trade significantly below $1. The TerraUSD (UST) crash in May 2022 saw its value fall from $1 to $0.10, wiping out $45 billion. Even USDC briefly dropped to $0.87 during the March 2023 SVB banking crisis before recovering within four days. Depegging risk is real.
Are stablecoins backed by real dollars?
Fiat-backed stablecoins like USDC and USDT claim dollar backing, but reserve composition varies. USDC holds primarily cash and US Treasury bonds. USDT holds a mix of cash, Treasury bills, commercial paper, and other assets. Crypto-backed stablecoins like DAI are backed by cryptocurrency collateral instead of dollars.
Why would I use stablecoins instead of regular dollars?
Stablecoins offer 24/7 instant transfers, settlement in minutes rather than days, lower fees for international payments, and access to DeFi yield opportunities. They're essential for crypto trading, useful for cross-border remittances, and provide dollar access in countries with limited banking or high inflation.
How do stablecoins make money?
Stablecoin issuers earn interest on the reserve assets backing their tokens. With US Treasury yields around 5%, issuers earn substantial returns on billions in reserves. Tether reportedly earned over $6 billion in profit during 2024 from reserve interest alone. Users holding stablecoins don't receive this yield—issuers keep it.
What blockchain are stablecoins on?
Major stablecoins operate across multiple blockchains for maximum accessibility. USDT exists on Ethereum, Tron (largest share), Solana, Arbitrum, and others. USDC runs on Ethereum, Solana, Base, Arbitrum, and more. This multi-chain presence ensures users can access stablecoins on their preferred network.
Can I convert stablecoins to cash?
Yes. You can sell stablecoins for USD on exchanges like Coinbase, Kraken, or Gemini, then withdraw funds to your bank account. Institutional holders can redeem directly with issuers—Circle allows USDC redemption where tokens are burned and USD is wired to your bank. Exchange withdrawal typically takes 1-3 business days.
What's the difference between USDT and USDC?
The key differences are transparency and regulation. USDC undergoes monthly audits by Deloitte with full reserve disclosure and is compliant with US and EU regulations. USDT has never completed a full audit, provides limited reserve transparency, and isn't MiCA-compliant in Europe. USDT has larger market cap ($145B vs $73B) and more trading volume, making it more liquid.
What happens if Tether collapses?
A Tether collapse would trigger a severe crypto market crisis given its $145 billion market cap and role as the primary trading pair on many exchanges. Crypto prices would likely crash as traders flee to other stablecoins or fiat. Exchange liquidity would evaporate. This systemic risk is why Tether's reserve transparency matters to the entire market.
Are algorithmic stablecoins safe?
Algorithmic stablecoins carry high risk and are generally not recommended. They have no asset backing and rely purely on code-based supply adjustment. TerraUSD's $45 billion collapse demonstrated the "death spiral" vulnerability—when confidence breaks, algorithms can't restore the peg. Most financial experts recommend avoiding purely algorithmic stablecoins.
Can the government ban stablecoins?
Governments can and do restrict stablecoins. The US now regulates them under the GENIUS Act, requiring reserves and licensing. The EU's MiCA effectively blocks non-compliant stablecoins like USDT from regulated platforms. Some countries may ban stablecoins entirely as threats to monetary sovereignty. Operating in regulatory gray areas carries legal risk.
What's the best interest rate for stablecoins?
Top stablecoin lending rates currently range from 4-8% APY depending on platform and risk tolerance. Nexo offers up to 8% on USDT. DeFi protocols like Aave offer 4-6% variable rates. Higher rates generally mean higher risk—consider the platform's track record and security carefully. /blog/compare/stablecoin-rates to see current rates.
Is earning interest on stablecoins taxable?
Yes, in most jurisdictions. Stablecoin interest is typically treated as ordinary income and taxed at your marginal income tax rate. In the US, you must report all cryptocurrency interest earnings to the IRS, regardless of whether you received a 1099 form. Consult a tax professional familiar with crypto for your specific situation.
Will stablecoins replace traditional banking?
Stablecoins are disrupting payments but won't fully replace banking. They excel at fast, cheap transfers and 24/7 availability. However, banks still provide lending, FDIC insurance, mortgage origination, and other services stablecoins can't replicate. More likely: stablecoins become another payment rail that banks integrate rather than a banking replacement.
What's the future of stablecoin regulation?
Global regulation is accelerating. The US GENIUS Act and EU MiCA established comprehensive frameworks in 2024-2025. More countries are following with their own licensing regimes. Expect stricter reserve requirements (1:1 high-quality assets), mandatory regular audits, issuer licensing, and potentially limits on non-compliant stablecoins accessing regulated financial infrastructure. Compliant stablecoins will benefit; others may face restrictions.
