Synthetix USD (sUSD), the crypto-collateralized stablecoin of the Synthetix protocol, plunged to $0.83 on April 10—its lowest value in five years—raising fresh concerns about the token’s ability to maintain its dollar peg.

The drop caps off a turbulent start to 2025 for the stablecoin. sUSD slipped to $0.96 on January 1 and has struggled to recover. Although it momentarily rebounded to $0.99 in early February, the peg has remained unstable, with April’s dive marking a sharp escalation in investor anxiety.

As a stablecoin backed by SNX, the Synthetix network’s native token, sUSD’s peg stability is directly tied to SNX’s market performance. This model introduces vulnerabilities similar to TerraUSD (UST), the now-defunct algorithmic stablecoin that collapsed in 2022.

Rob Schmitt, co-founder of Cork Protocol, highlighted the risk of a “death spiral” if sUSD redemptions exert too much sell pressure on SNX. “If the value of SNX drops sufficiently, sUSD is no longer fully backed,” Schmitt explained, warning of a cascading deleveraging event.

However, Schmitt tempered fears, noting Synthetix’s $30 million treasury—holding roughly half of the outstanding sUSD debt—could act as a buffer. “This sUSD can be unwound to avoid a death spiral,” he added.

Synthetix founder Kain Warwick also weighed in, downplaying fears of collapse. “We’re transitioning mechanisms, so there will be volatility,” he wrote. Warwick emphasized that while the peg may drift, built-in mechanisms will restore alignment over time.

The recent sUSD instability mirrors broader trends. On April 7, another stablecoin, syUSD, fell to $0.94 amid concentrated selling. The project blamed the deviation on market conditions and promised improvements to its redemption system.

As crypto markets remain volatile, the spotlight is once again on the fragility of decentralized stablecoins. Whether sUSD can recover its peg and regain investor trust may depend not just on treasury reserves but on how swiftly and effectively Synthetix deploys new stabilization tools.
