The stablecoin market has pulled back by about $14.6 billion from its May 2026 high, falling from roughly $322 billion to about $307.6 billion by early August, according to the source article. The decline comes as new U.S. federal stablecoin rules reduced interest payments on digital dollars, prompting some capital to move elsewhere.

Stablecoins are designed to hold a one-to-one value with the U.S. dollar, but past episodes show that the peg depends on redemption systems, market confidence, and functioning banking links rather than code alone. The article points to several notable breaks from parity, including USDC’s drop to $0.87, USDT’s fall to about $0.88, Terra’s UST collapse, and xUSD’s sharp losses in 2025.

Why a $1 peg can fail

A stablecoin’s dollar price is maintained mainly through redemption and arbitrage. If the token trades below $1, traders can buy it at a discount and redeem it with the issuer for one dollar, a process that can help push the market price back up. If it moves above $1, additional tokens can be minted and sold at par. In that framework, the peg works because market participants believe the redemption process will hold.

The article stresses that this mechanism is not equally available to everyone. Direct redemption is often limited to verified or institutional users, while retail holders and DeFi platforms rely on arbitrageurs to step in during periods of stress. That means confidence, access, and speed matter as much as reserve claims when markets turn volatile.

Four depegs with different triggers

The source highlights four separate breakdowns to show that stablecoins can lose parity for very different reasons. In October 2018, USDT reportedly fell to around $0.88 amid concerns over Tether’s solvency and its ties to affiliated exchange Bitfinex. The peg later recovered as redemptions continued.

In March 2023, USDC dropped to $0.87 after $3.3 billion of Circle reserves became trapped at Silicon Valley Bank during the bank’s failure. Regulators later guaranteed deposits, helping USDC recover, but the move also spread to other crypto assets, with DAI falling to about $0.89. In November 2025, Stream Finance’s xUSD sank after a disclosed $93 million loss tied to external fund managers and a freeze on withdrawals, with the token said to have dropped as low as $0.24.

The most severe example in the article is terraUSD, or UST. In May 2022, the algorithmic stablecoin’s design failed under withdrawal pressure, sending UST below $0.10 while LUNA’s supply expanded sharply. The collapse erased roughly $40 billion across the two tokens and rippled through hedge funds, lenders, and FTX’s ecosystem, according to the source.

2026 contraction and concentration risk

The current year has so far looked less like a sudden panic and more like a broad retreat. The article says the stablecoin market began 2026 near $310 billion, climbed to around $322 billion in May, and then lost about $14.56 billion by early August. Major issuers including USDT and USDC saw declines, while some competitors either held steadier or gained market share.

Even after that pullback, the market remains highly concentrated. USDT and USDC together account for roughly 83% of the $307.6 billion total cited in the article. That concentration can support market liquidity and day-to-day trading, but it also means any shock affecting either issuer’s reserves, banking partners, or regulatory position could have outsized effects across the sector.

What the next stress event may show

The article argues that the type of depeg matters. A reserve-backed token hit by fear or a temporary banking disruption may regain parity if redemptions continue to function. By contrast, structures that depend on internal tokens or less transparent yield strategies may face deeper solvency questions and may not recover in the same way.

As a result, the next confirmed step in assessing any future depeg is not just watching the market price. The source suggests focusing on whether withdrawals and redemptions are still being processed and whether stress is spreading into other tokens or platforms. Those signals, rather than price alone, can offer the clearest indication of whether a break below $1 is a short-lived dislocation or a more serious failure.
