Collateralized vs Algorithmic Stablecoins: What’s the Difference?

September 26, 2025

Stablecoins have become a cornerstone of the crypto economy as well as cross border payment rails. They offer the best of attributes and benefits of the blockchain - speed, transparency and programmability while maintaining a stable value - these are typically pegged to a fiat currency like US Dollar. However, if we dig deeper, not all stablecoins achieve their stability the same way. Two key models dominate this landscape: Collateralized stablecoins and Algorithmic stablecoins. For businesses, investors and developers, it's important to understand their mechanics, strengths and risks while exploring these blockchain based payments.  

Types of stablecoins

Before understanding the two main categories, it helps to understand the broader clarification that stablecoins fall into;

  1. Fiat-backed stablecoins - these are fully collateralized by fiat currency which is held in their bank accounts (eg, USDC, USDT)
  1. Crypto backed stablecoins - these are overcollateralized with crypto currencies such as ETH and BTC (e.g. DAI)
  1. Commodity backed stablecoins - these ones are pegged to assets like gold (eg. PAX Gold)
  1. Algorithmic stablecoins - these stablecoins maintain their peg via code driven supply/demand mechanisms rather than explicit collaterals. 

In this article, we’ll focus on collateralized (fiat or crypto) and algorithmic stablecoin categories.  

Collateralized stablecoin  

How they work

Collateralized stablecoins are issued when a user deposits collateral - fiat money or cryptocurrencies into a reserve or smart contract. The value of the collateral, in this case, equates or exceeds the value of stablecoin in circulation. 

Examples 

  • Fiat backed: USDT (Tether) and USDC (Circle), BUSD, PYUSD.
  • Crypto backed: DAI (overcollateralized with ETH and other assets), sUSD, LUSD. 

Peg mechanism 

  • Each of these tokens redeemed 1:1 for the underlying asset.
  • Independent audits or on-chain proofs are reassurance for users of reserves 

Pros 

  • These have high stability as they are pegs supported by real collateral.
  • They are business friendly as they pose clear redemption and regulatory pathways.
  • For reputable issuers, they entail transparent accounting providing attestation or on chain data. 

Cons

  • They come with a potential for centralized risk (fiat backed) and require trust in custodians/banks.
  • Crypto backed ones hold Capital inefficiency in some cases - Overcollateralization demands excess assets. 
  • They have a regulatory dependence where bank partnerships and audits can be disrupted and damaged. 

Algorithmic stablecoin 

How they work

Algorithmic stablecoins use smart contracts and monetary policy algorithms to automatically contract or expand token supply based on market demand. 

Typical mechanism 

  1. rebase/elastic supply - if their price rises above 1$, the protocol mints new tokens to automatically push the price down.
  2. Dual token systems - A “governance” or “share” token absorbs this volatility (e.g., Terra’s LUNA burned to mint UST). 

Examples 

  • TerraUSD (UST) - collapsed in 2022.
  • Ampleforth (AMPL) - uses rebase mechanism.
  • FRAX - It’s a hybrid combining algorithmic and collateral coin type.

Pros 

  • It stands with capital efficiency which means there is no need for large collateral reserves.
  • It has a decentralisation potential and can operate without banks and custodians. 

Cons 

  • Pegs can be fragile, which means price stability depends on market confidence.
  • Sudden sell offs can cause uncontrolled supply changes leading to a death spiral. 

Business uses and considerations

Collateralized stablecoins 

  1. Payment and settlement - USDC, USDT and PYUSD are widely and majorly accepted for B2B settlements.
  1. Payroll and remittance - their low volatility makes them ideal for cross border payroll. 
  1. Treasury management - businesses can cover up against fiat depreciation with crypto backed coins like DAI. 

Algorithmic stablecoins 

  1. Decentralized Finance (DeFi) - these are preferred by some protocols to avoid banking friction.
  1. High yield opportunities - when functioning properly, algorithmic stablecoins can offer attractive liquidity rewards. 

It's important to not that after the UST collapse, businesses remain cautious of algorithmic coins for mission critical payments. 

Stablecoin models and the future

  1. Hybrid approaches - FRAX and other projects are known to blend collateral and algorithmic supply to balance efficiency and stability. 
  1. Regulation and Audits - it is expected that tighter rules for fiat backed issuers and stress testing for algorithmic models is on the rise. 
  1. Business trend - most companies are opting for collateralized stablecoins as they offer reliability and regulatory clarity.
