Stablecoins are digital currencies designed to maintain a stable value, often pegged to fiat currencies like ₹ or US$. They are widely used in India’s growing crypto market for low-cost transactions, asset protection from volatility, and predictable DeFi activities. Here’s how they maintain their pegs:
- Collateral Systems: Backed by reserves like fiat (₹, US$), crypto (e.g., Bitcoin, Ethereum), or commodities (e.g., gold). Examples: USDT, USDC, DAI.
- Algorithmic Controls: Use smart contracts to adjust supply with mechanisms like rebasing or seigniorage shares. Example: UST (now defunct).
- Market Operations: Issuers actively intervene using reserve management, market making, and emergency protocols.
Quick Comparison of Peg Mechanisms
| Mechanism Type | Reserve Backing | Decentralisation | Market Resilience | Examples |
|---|---|---|---|---|
| Fiat‑Collateralised | Backed by fiat reserves | Low | Strong | USDT, USDC |
| Crypto‑Collateralised | Over-collateralised in crypto | Medium | Moderate | DAI |
| Algorithmic | No direct reserves | High | Unstable | UST (defunct) |
| Hybrid | Mix of reserves and algorithms | Medium–High | Moderate–High | FRAX |
Stablecoins are essential for bridging traditional finance and blockchain, but maintaining their pegs requires transparency, robust reserves, and strong operational systems to handle risks like market stress and regulatory challenges.

Main Peg Maintenance Methods
Stablecoins use three main methods to keep their value stable. Each method has its own approach and requirements.
Collateral Systems
These stablecoins are backed by reserves such as fiat money, cryptocurrencies, or commodities to maintain their value.
- Fiat Currency: Reserves in currencies like ₹ or US$ held in bank accounts.
- Cryptocurrencies: Digital assets like Bitcoin or Ethereum, often over-collateralised to handle price volatility.
- Commodities: Physical assets like gold, stored with regulated custodians.
Issuers typically provide regular audits to confirm these reserves. Each type of collateral involves trade-offs between liquidity, costs, and audit requirements.
Algorithmic Controls
Algorithmic stablecoins rely on smart contracts to automatically adjust their supply based on demand.
- Rebase Functions: Automatically increase or decrease supply when the price changes.
- Seigniorage Shares: Mint or burn tokens according to protocol rules.
- Bond or Coupon Systems: Issue bonds or coupons to encourage arbitrage and stabilise the value.
While these models are efficient in terms of capital use, they can be more fragile during market stress.
Market Operations
This method involves active intervention by issuers to stabilise the peg.
- Reserve Management: Adjust reserves and conduct stress tests to ensure stability.
- Market Making: Work with market makers to improve liquidity.
- Emergency Protocols: Implement measures like circuit breakers or inject reserves during extreme situations.
These interventions can be costly and carry risks, which will be discussed in the next section.
Risks and Limits
Stablecoins aim to keep their value steady, but several challenges can impact their ability to do so.
Reserve Verification
Transparency around reserves is critical, but it’s often not up to the mark. Issues like irregular audits, holding assets that can’t be quickly converted to cash, and weak reporting standards can shake user confidence. Beyond reserves, factors like market fluctuations and technical glitches also pose risks to maintaining the peg.
Market Stability Issues
Unstable cryptocurrency markets can put additional pressure on stablecoin pegs. Redemption surges and arbitrage activities can destabilise a peg, especially during market stress. On top of that, technical problems – such as oracle failures or network congestion – can worsen these vulnerabilities.
In India, where regulations are still taking shape, stablecoin issuers face the added challenge of complying with banking laws and reporting standards. To keep their pegs stable, they need strong operational systems and a solid risk-management plan.

Comparing Peg Methods
Stablecoin mechanisms differ in how well they maintain their pegs. Here’s a breakdown of the main approaches, focusing on reserve backing, decentralisation, and market resilience.
Method Comparison Data
| Mechanism Type | Reserve Backing | Decentralisation | Market Resilience | Notable Examples |
|---|---|---|---|---|
| Fiat‑Collateralised | Backed by full fiat reserves | Low | Generally high | USDT, USDC |
| Crypto‑Collateralised | Over‑collateralised in crypto | Medium | Moderate | DAI |
| Algorithmic | No direct reserves | High | Variable | UST (now defunct) |
| Hybrid | Mix of reserves and code‑based adjustments | Medium–high | Moderate–high | FRAX |
The right mechanism depends on factors like the intended use case, current market dynamics, and regulatory requirements. Up next, we’ll explore how India’s regulatory framework and market characteristics influence stablecoin adoption.
Comparing Peg Methods
Stablecoins use different mechanisms to maintain their pegs. Here’s a quick look at the main types, evaluating their reserve backing, level of decentralisation, and performance under market pressure.
Method Comparison Data
| Mechanism Type | Reserve Backing | Decentralisation | Market Resilience | Notable Examples |
|---|---|---|---|---|
| Fiat‑Collateralised | Fully backed by fiat reserves | Low | Generally strong | USDT, USDC |
| Crypto‑Collateralised | Backed by over-collateralised crypto | Medium | Moderate | DAI |
| Algorithmic | No direct reserves | High | Unstable | UST (now defunct) |
| Hybrid | Combines reserves with code-based adjustments | Medium–high | Moderate–high | FRAX |
Choosing the best mechanism depends on factors like the specific use case, market conditions, and regulatory considerations. Each type has its strengths and weaknesses, making it crucial to match the mechanism to the intended application.
Summary and Training
Let’s quickly recap the key methods stablecoins use to maintain their value and how you can deepen your understanding through training.
Key Takeaways
Stablecoins use three main approaches to maintain their peg:
- Collateralised: Examples like USDT and USDC are backed 1:1 with fiat reserves.
- Algorithmic: These rely on smart contracts to adjust supply but can struggle under stress (e.g., UST).
- Hybrid: Combines reserves and algorithms to balance stability and efficiency.
Understanding these mechanisms is essential, and hands-on training can help solidify your knowledge.
