The Synthetix network’s algorithmic stablecoin, sUSD, has again lost parity with the US dollar, dropping roughly 6% over the past day to trade around $0.8597. This deviation marks a continuation of its recent struggles to maintain the crucial $1 peg.
Concurrent with the price dip, trading activity for sUSD has exploded. According to CoinGecko figures, the 24-hour trading volume surged by nearly 487%, exceeding $2.1 million. This spike indicates heightened market interest and potential anxiety surrounding the stablecoin’s stability.
[This reflects growing market activity as concerns rise.]
Synthetix operates as a decentralized finance (DeFi) platform enabling the creation and trading of synthetic assets, designed to mirror real-world asset values on the blockchain. Its stablecoin, sUSD, theoretically tracks the US dollar and is collateralized by the protocol’s native token, SNX, utilizing oracle price feeds.
The latest instability follows the implementation of Synthetix Improvement Proposal 420 (SIP-420). This update introduced the “420 Pool,” significantly reducing the collateralization requirement for minting sUSD from 500% down to 200%.
Market analysts suggest this lowered barrier dramatically increased the circulating supply of sUSD, exerting downward pressure on its price peg. DeFi analyst Panterafi highlighted on X (formerly Twitter) on April 2nd that this oversupply, combined with yield farming strategies involving sUSD sales, is fueling the de-pegging.
[Synthetix developers have described this as a “transitionary period.”]
Despite the stablecoin remaining overcollateralized by SNX, its peg is now seemingly more influenced by open market dynamics rather than direct arbitrage or conventional debt settlement mechanisms within the protocol.
The Synthetix team, communicating via their official Discord channel, acknowledged the excess sUSD supply as part of a “transitionary period.” They outlined plans to counteract the price pressure by increasing liquidity pool incentives and developing further uses for sUSD, including the upcoming Snaxchain initiative.
“During this transition there is excess sUSD in the market causing pressure on the price of sUSD (which is still healthily over-collateralised). We will continue to work on managing (increasing in the short term) incentives for curve pools, supporting the Infinex deposit campaign (will extend) and creating additional sinks for sUSD that will provide long term price support (snaxchain coming)”

[This isn’t the first time sUSD has slipped below its peg.]
This is not the first instance of sUSD losing its $1 anchor; similar events occurred in March and May 2024, prompting reassurances from core contributors about ongoing stabilization efforts.
While the Synthetix team and founder Kain Warwick express confidence, seeing the depeg as a temporary effect of SIP-420 rollout (Warwick recently increased his SNX holdings), some observers remain skeptical. DeFi analyst Eldar voiced concerns on X that the current model might struggle to maintain the peg long-term without more tangible value backing the core SNX token.
[However, Kain Warwick, the founder of Synthetix, is still hopeful.]
The situation underscores the persistent challenges faced by algorithmic stablecoins in maintaining their pegs, especially when protocol changes significantly alter supply dynamics.
