When a Stablecoin Loses Its Peg: Understanding the Phenomenon of Depeg

Depegging is a phenomenon where a stablecoin deviates from its nominal value. This occurs with assets pegged to traditional currencies. Let’s understand why this happens and what consequences it has for the crypto market.

How the Depegging Mechanism Works for Stablecoins

The most well-known example is Tether (USDT). This coin promises to maintain a value of $1, but its value depends solely on users’ trust in Tether Limited. In theory, each token should be backed by an equivalent amount in US dollars in the company’s accounts.

However, there is no internal mechanism to guarantee this. Stablecoins exist based on trust. When that trust begins to waver, when questions arise about the company’s reserves or liquidity issues occur, the token loses its parity. At this moment, a break in the peg happens — the stablecoin starts trading below its set rate.

Historical Examples of Parity Breaks in the Market

The year 2022 was marked by one of the most high-profile cases. The algorithmic stablecoin UST (Terra USD) by Terraform Labs completely lost its peg to the dollar and subsequently collapsed. This was a systemic failure of the mechanism meant to maintain the value.

A more recent example is from March 2023. During this period, BUSD and USDC experienced pressure due to market fears. Both tokens temporarily lost their 1:1 parity with the dollar, although they later recovered. This episode demonstrated the vulnerability of stablecoins even from major issuers.

Analysts noted a worrying trend: throughout 2023, the stability of leading stablecoins in the crypto market significantly weakened. The risk of depegging shifted from a theoretical threat to a real market danger.

Risks of Depegging: What Investors Need to Know

When depegging occurs, investors holding their funds in such coins face unexpected losses in value. The effect can spread across the entire crypto sector, causing panic runs from stablecoins and significant volatility.

Understanding the depegging mechanism is crucial for any participant in the cryptocurrency market. This phenomenon shows that even assets positioned as risk-free carry certain threats and require constant monitoring.
