SUI Drops 10% From Sunday’s High: What’s Behind the Pullback?

Sui (SUI) has slipped nearly 10% from Sunday’s high, raising questions about whether the altcoin’s recent rally is beginning to lose momentum. 

The decline follows a sharp breakout that saw SUI surge almost 40% over the past week, making it one of the market’s top-performing altcoins.

SUI Staking Powered the Rally

Market data revealed that SUI climbed to an intraday high of $1.42 on Sunday, its highest level since late January, before retreating. A key catalyst came from SUI Group Holdings.

The firm revealed that it had expanded its treasury holdings to 108,728,129 SUI. It added that “substantially all” of those holdings are now staked at an estimated 1.8% yield. The shift pulled another 2.7% of supply off the liquid market. 

“Two more catalysts compounding: CME Group SUI futures launching May 29 (only the fifth L1 with regulated derivatives access), and Paga partnership for cross-border African payments,” Santiment said.

What’s Behind SUI’s 10% Price Drop  

Despite the strong rise, SUI pulled back. At press time, the altcoin traded at $1.273, down 4% over the past 24 hours and nearly 10% below Sunday’s peak.

The correction came after SUI’s Relative Strength Index (RSI) surged into heavily overbought territory at 84.4 before cooling to 75.94, suggesting the pullback may reflect a natural market reset following rapid gains.

The broader crypto market also weakened, with total market capitalization slipping 0.33% over the past day amid losses across several altcoins.

“RSI hit 84 yesterday. That’s deeply overbought. A cooldown was inevitable. The broader market also shifted risk-off today. $680M in outflows from BTC and ETH into stablecoins. SUI didn’t dump alone — the whole market did,” an analyst wrote.

Network Activity Continues to Strengthen

Meanwhile, on-chain activity within the Sui Network ecosystem remains strong. DefiLlama data showed that the total value locked (TVL) climbed to around $653 million, up from roughly $541.9 million at the start of May.

Stablecoin supply on the network also rose 4.5% over the past week, while decentralized exchange volumes jumped over 200%.

Santiment further noted that SUI’s social dominance during the rally ranged between 0.13% and 0.15%, still below the 0.38% spike recorded on May 6.

“The conversation isn’t outrunning the price. Institutional supply locks driving a rally look different on-chain than retail FOMO,” the post added.

Nonetheless, SUI remains roughly 76% below its all-time high and continues to trade below its early-2026 peaks, keeping the token in negative year-to-date territory. 

Therefore, whether SUI reclaims its January peak depends on investor demand and corporate treasury inflows outpacing monthly token unlocks. Continued network growth and sustained buying pressure could determine the strength of the next move higher.
