Undercollateralized Stablecoin
Pronunciation: UN-der-kuh-LAT-er-uhl-ized STAY-bul-koyn
Also known as: Partially Collateralized Stablecoin, Fractionally Backed Stablecoin
Definition
Undercollateralized Stablecoin is a stablecoin whose identifiable collateral value is lower than the outstanding token liabilities or whose design relies materially on future revenue, unsecured credit, algorithmic incentives, insurance, governance tokens, or market confidence instead of full asset backing.
Overview
How it works and why it matters
An undercollateralized stablecoin arrangement has backing that does not fully cover its stated liabilities under a chosen valuation and risk model. Depending on structure, it may use algorithmic supply adjustments, future revenue, junior capital or unsecured exposures instead of fully liquid reserves. Assessing coverage requires identifying which assets actually exist, their liquidity and credit quality, and who bears losses first. A quoted peg cannot compensate for a shortfall in reliable assets when redemptions surge.
Technical context
It differs from an overcollateralized stablecoin, which maintains excess collateral to absorb losses, and from a fully reserved stablecoin backed at least one-for-one by eligible reserves.
Practical checks
Define the collateral coverage test precisely: mark-to-market assets, expected recovery on default, liabilities due on demand and obligations from related derivatives. Paper asset values may be poor estimates of cash proceeds during a run. Check which token holders bear the first losses and whether redemption may be suspended.

Example
A stablecoin project has $90 million of readily recoverable assets against $100 million of redeemable token claims. If holders request redemption together, the missing $10 million creates a solvency or loss-allocation problem unless external support arrives.
Comparison
Undercollateralization is not the same as ordinary daily market-price deviation. A token can trade near par even when backing is weak, or trade below par temporarily while high-quality backing remains available.
Key Takeaway
Compare realistic reserve recoverability with all relevant redemption obligations.
