The cryptocurrency ecosystem has undergone a pragmatic shift from Bitcoin's original vision of replacing traditional currencies to embracing stablecoins—digital assets designed to maintain a fixed value, typically pegged to the U.S. dollar. This evolution addresses Bitcoin's volatility and scalability challenges, positioning stablecoins as the backbone of crypto transactions, payments, and decentralized finance (DeFi).
The Rise of Stablecoins
Stablecoins bridge traditional finance and crypto ecosystems, offering stability, efficiency, and widespread adoption. Their market capitalization has surged from under $3 billion in 2017 to over $228 billion in 2025, accounting for 8.57% of the total crypto market.
What Are Stablecoins?
Stablecoins are cryptocurrencies pegged to external assets like fiat currencies or commodities. Examples include Tether (USDT) and USD Coin (USDC), which maintain a 1:1 peg to the dollar through collateralized reserves. Their primary purpose is to enable fast, borderless transactions without the volatility of assets like Bitcoin.
Types of Stablecoins and Their Revenue Models
1. Fiat-Backed Stablecoins (e.g., USDT, USDC)
Mechanism:
- Users deposit $1 to mint 1 stablecoin; redemptions destroy tokens and return $1.
- Issuers invest reserves in short-term instruments like U.S. Treasuries, generating interest income.
Revenue Drivers:
- Interest from reserves (e.g., T-bills, repos).
- High reliance on central bank rates—profits soar in high-rate environments but plummet near 0%.
Risks:
- Regulatory scrutiny: Compliance challenges (e.g., MiCA regulations banning USDT in Europe).
- Depegging: Bank run risks (e.g., USDC’s brief depeg during the 2023 SVB crisis).
2. Commodity-Backed Stablecoins (e.g., PAXG, XAUT)
Mechanism:
- Pegged to physical assets like gold.
- Revenue from minting/redemption fees and trading services.
Risks:
- Commodity price volatility.
- Strict custodial and regulatory requirements.
3. Crypto-Backed Stablecoins (e.g., DAI, HONEY)
Mechanism:
- Overcollateralized with crypto assets (e.g., ETH) or wrapped stablecoins (e.g., USDC).
- Revenue from stability fees, liquidation penalties, and protocol incentives.
Risks:
- Crypto asset volatility triggering liquidations.
- Smart contract vulnerabilities.
4. Treasury-Backed Stablecoins (e.g., USDY, USYC)
Mechanism:
- Backed by short-term U.S. Treasuries, offering yield-bearing tokenized notes.
- Passive income for holders via interest distributions.
Risks:
- Regulatory uncertainty for non-U.S. users.
- Custody and counterparty risks.
5. Algorithmic Stablecoins (e.g., USDe)
Mechanism:
- Delta-neutral hedging using crypto assets and perpetual futures.
- Revenue from funding rate arbitrage, staking rewards, and basis trading.
Risks:
- Sensitivity to crypto market leverage and volatility.
Interest Rates and Stablecoin Profitability
Correlation Analysis
- USDT/USDC/SKY: Strong positive correlation (R = 0.89–0.94) with interest rates. Income relies heavily on Treasury yields.
- USDe: Weak correlation (R = 0.26). Revenue depends on crypto-native mechanisms like funding rates, making it resilient to rate cuts.
Impact of 0% Interest Rates
Tether (USDT):
- $200 billion in equity ensures decades of runway despite income drop.
- Diversified into BTC, gold, and low-cost operations.
Circle (USDC):
- Vulnerable with 18–25 months of sustainability due to high reliance on reserve income ($16.8B in 2024).
SKY (DAI/USDS):
- 2.89–6.29 years of operational buffer via DeFi fees and governance tokens.
Ethena (USDe):
- Thrives in low-rate environments due to funding rate arbitrage. $61M reserve fund supports stability.
Conclusion
Stablecoin issuers face divergent futures in a 0% rate world:
- Fiat-backed models (USDT/USDC) risk revenue collapse but benefit from robust reserves or IPO strategies (e.g., Circle’s public listing).
- Algorithmic stablecoins (USDe) leverage crypto-native yield, offering adaptability.
Key Insight: Diversification beyond traditional interest-bearing assets is critical. Protocols like USDe exemplify resilience, while others must innovate to survive.

FAQs
Q: Can stablecoins survive without interest income?
A: Yes, but models like USDe (algorithmic) or diversified reserves (Tether) fare better than pure fiat-backed ones.
Q: What happens if USDC depegs again?
A: Circle’s transparency and liquidity measures aim to prevent repeats, but systemic risks persist.
Q: Are algorithmic stablecoins safer than fiat-backed ones?
A: They’re less sensitive to rate cuts but face crypto market risks (e.g., negative funding rates).
