The stablecoin market recorded a $12.4 billion outflow over a 62-day period from May 17 to Jul 18, 2026, according to Defillama data released Saturday. The sector lost $1.5 billion in value since Jul 11 alone, marking the largest contraction in over four years. Tether's USDT maintained a $184.055 billion market cap while Sky's USDS dropped 12.3% and Global Dollar's USDG climbed 9.08%, revealing widening divergence among issuers. The pullback occurred during a stretch when Bitcoin and major altcoins largely held their ground, separating this decline from typical risk-off market panics. The timing suggests the stablecoin sector may be shifting toward competition based on yield and utility rather than serving solely as a digital dollar parking space.
Tether and Circle Hold Ground as Sky USDS Records Largest Weekly Decline
Tether's USDT held a $184.055 billion market cap as of Saturday, while Circle's USDC followed at $73.376 billion. USDT declined 0.06% over the past week and USDC slipped 0.04%. Sky's USDS ranked third at $6.66 billion but recorded the hardest hit among the top 10 stablecoins, tumbling 12.30% over the seven-day period.
Dai (DAI), World Liberty Financial's USD1 and Ethena's USDe occupied the middle positions, with USD1 falling 4.59% over the past week and Sky's DAI edging 0.43% lower. Circle USYC and Blackrock's BUIDL declined 3.64% and 8.68%, respectively, leaving BUIDL with a $2.633 billion market cap.
Global Dollar USDG Posts 9.08% Weekly Gain While Yield-Bearing Stablecoins Show Mixed Results
Global Dollar's USDG recorded the strongest weekly performance among the top 10 stablecoins, climbing 9.08% to a $3.164 billion market cap. PayPal's PYUSD added 1.60% to reach $2.877 billion.
The mixed performance across tokenized treasury and yield-bearing stablecoins indicates this segment is still sorting itself out, according to the source, even as the two largest fiat-backed issuers barely broke a sweat.
Stablecoin Outflow Begins Mid-May as Bitcoin and Altcoins Maintain Stability
The contraction began in mid-May and accelerated during a period when Bitcoin and most major altcoins largely held their ground instead of declining. The stablecoin pullback did not move in lockstep with a broader market selloff, according to the source analysis.
The timing separates the stablecoin decline from the usual risk-off panic narrative. The source notes that issuers increasingly compete on yield, features and utility instead of merely offering a digital parking space for dollars.
