Stablecoin Depeg Risk: What Happens When One Dollar Is Not One Dollar?

A stable price target is not the same as a guaranteed cash value

Stablecoins use different mechanisms to target a reference value. Some rely on reserves and redemption arrangements; others rely on collateral, market incentives or protocol rules. Whatever the design, the market price can move away from the intended peg when holders become uncertain about redemption, liquidity or the assets supporting the system.

Suppose a fictional stablecoin normally trades near USD 1.00 but falls to USD 0.92. A holder with 5,000 units now has a secondary-market value of about USD 4,600 rather than USD 5,000 if the entire position is sold at that price before costs.

That is an 8% market discount:

(1.00 - 0.92) ÷ 1.00 = 8%

Market price and redemption value can diverge

The key analytical question is whether holders can actually redeem the token near the reference value, through whom, under what conditions and on what timeline. A direct redemption route may be available only to certain eligible users, may have minimums, may require banking access or may take time. Secondary-market traders therefore price not only the reserves but also the practical path to turn the token into usable money.

A statement such as “fully backed” is not enough for risk analysis. You would still need to know what the backing consists of, how it is held, what claims holders have, and whether the redemption mechanism is usable under stress.

The final PHP outcome adds another layer

For a Philippine user, the practical question may be how many pesos arrive after the stablecoin is sold and converted. Even if the token returns to USD 1.00 later, a user who needs PHP immediately can be exposed to the temporary depeg, exchange spread, fees and USD/PHP conversion at the time of exit.

Assume 5,000 units sell at USD 0.92 and the illustrative USD/PHP rate is PHP 58.00 before other costs:

5,000 × 0.92 × 58 = PHP 266,800

At USD 1.00 the same conversion would be PHP 290,000. The difference is PHP 23,200 before fees and spread. The example shows why “stable” should be treated as a mechanism to investigate, not a promise to assume.

Depeg risk is also liquidity and confidence risk

A depeg can widen when many holders try to exit through the same market. Spreads can increase and depth can disappear. In other cases the market discount may recover quickly if credible redemption remains available. The same observed price therefore needs context: reserve concerns, redemption access, market depth and timing.

No-money practice

Create three scenarios for 10,000 fictional units: market prices of USD 1.00, USD 0.97 and USD 0.85. Calculate the value difference and then add a PHP conversion. Write separately what you know about the secondary-market price and what you would still need to verify about redemption.
