## How Does the Collateralization Ratio Differ between Algorithmic and Fully Backed Stablecoins?

Fully backed stablecoins (like USDC) aim for a 1:1 ratio, meaning $1 of fiat or equivalent collateral for every stablecoin. Algorithmic stablecoins, by design, are either under-collateralized or not collateralized at all, relying purely on market mechanisms.

This lack of physical backing is the core vulnerability that makes them susceptible to death spirals when confidence fails.

Over-collateralization acts as a buffer against the high volatility of crypto collateral to prevent under-collateralization and liquidation.

Fully paid-for assets have zero rehypothecation risk; margined assets are exposed to the broker's credit risk up to 140% of the debit balance.

Crypto-backed is more decentralized than fiat-backed, but algorithmic aims for pure code-based decentralization, often at a higher systemic risk.

PoA greatly mitigates the problem by adding an initial PoW cost, but the PoS signing phase means a residual, though highly impractical, risk remains.

A catastrophic feedback loop where the stablecoin's price drop causes the collateral token's value to drop, further accelerating the stablecoin's collapse.

Below these arms, lighter beige interlocking plastic or composite parts form a base structure, suggesting intricate mechanical engagement. This abstract arrangement powerfully models the complex infrastructure underpinning modern financial engineering within decentralized autonomous organizations managing complex financial products. The structure visually represents the need for robust, low-latency execution mechanisms essential for calculating implied volatility surfaces for exotic crypto options, particularly American-style contracts settled in stablecoins. Understanding this mechanical fidelity mirrors grasping settlement guarantees in Layer 2 scaling solutions or the internal workings of automated market makers designed for mitigating basis risk in synthetic asset issuance. The precise contact point symbolizes the critical moment of trade execution or option expiration pricing against real time oracle data feeds, demanding fault tolerance analogous to robust governance token voting mechanisms ensuring protocol solvency against tail risk events inherent in decentralized perpetual swaps trading architecture."
