Depeg — This Is When a Stablecoin Loses Its Peg to Real Value

Depegging is a phenomenon that occurs when a stablecoin deviates from its set price. Simply put, depegging is a breach of the promise made by the project to token holders. For example, a stablecoin is supposed to be worth exactly $1, but for some reason, its price drops to $0.95 or $0.98. It may seem like a small issue, but in the cryptocurrency market, it’s a warning sign of danger.

How the peg system works and why depegging is possible

A stablecoin operates on the principle of trust. Take USDT from Tether as an example — the company guarantees that for every token issued, there is an equivalent amount in US dollars held in its bank accounts. Investors believe in this claim and use the token as a reliable store of value. However, if the company runs out of funds, or if there are problems with the banking system, or if users start demanding withdrawals en masse, the system can break down.

Depegging is not just a price drop — it’s a signal that the mechanism backing the stablecoin is not functioning properly. The market stops believing that the token is fully backed.

When depegging becomes a threat to investors

The crypto market has several high-profile examples. In 2022, the catastrophic collapse of UST by Terraform Labs occurred. This was an algorithmic stablecoin, meaning its value was maintained not by reserves but by complex mechanisms and an external token, Luna. When the system started to fail, depegging led to a complete crash — UST fell significantly below $1 and never recovered.

A less dramatic but illustrative case was in March 2023. Under the influence of panic and negative rumors (FUD — Fear, Uncertainty, Doubt), two major stablecoins temporarily lost their peg: BUSD and USDC. Although the crisis was contained thanks to regulatory intervention and the projects’ efforts, it demonstrated the vulnerability of even supposedly reliable tools.

What to watch out for

Depegging serves as a reminder that a stablecoin is not just a regular currency. It’s a financial instrument that depends on transparency, trust, and the proper functioning of backing mechanisms. Investors should monitor news about the reserves of issuing companies, their banking partners, and regulatory status. In 2023, the reliability of several leading stablecoins noticeably declined, prompting discussions about the need for more transparent reserve verification systems.

Understanding what depegging is and how it occurs helps cryptocurrency users avoid unpleasant surprises and make more informed decisions when choosing a stablecoin to store their funds.
