Stablecoins add $5.5B in 7 days as USDT, USDC supplies shift

TLDR

• Stablecoin market cap climbed roughly $5.5B over the past week.
• Gains consolidate momentum for dollar-pegged tokens across major networks.
• On a ~$300B base, the move equals a low single-digit gain.

The stablecoin market cap rose by about $5.5 billion over the past seven days. The increase consolidates recent momentum in dollar‑pegged tokens across major networks.

Weekly changes reflect net new issuance minus redemptions across fiat‑backed and crypto‑collateralized stablecoins. On a base near the low‑$300 billions, that move is a low‑single‑digit percentage gain.

Why this matters: liquidity, USDT–USDC supply, market share signals

Liquidity matters because stablecoins function as the cash leg for spot trading, derivatives margining, and cross‑exchange settlement. A larger circulating float can support deeper order books and smoother transfers.

USDT–USDC supply dynamics are a key signal. USDT often anchors exchange pairs and remittance corridors, while USDC’s compliance frameworks position it for institutional settlement; shifts in market share can foreshadow venue demand.

At the time of this writing, Coinbase Global (COIN) was quoted at $166.00 in after‑hours trading, a NasdaqGS delayed figure disseminated by Yahoo Finance. This market context does not imply any investment view.

What drove flows: settlement, exchange demand, and DeFi

Recent flows likely drew from three channels: payment and settlement initiatives, exchange inventory needs, and DeFi liquidity programs. Historical usage studies provide context on how such channels convert into on‑chain volume.

Institutional signals and prior analytics frame the drivers without assigning causation to prices. “Visa is doubling down on stablecoin settlement infrastructure as transaction volumes surge across digital dollar networks,” as reported by AOL.com/articles/visa-crypto-chief-bets-stablecoin-115917211.html">AOL, citing Visa Inc. “Stablecoins accounted for 30% of crypto transaction volume between January and July 2025,” said TRM in an October 21, 2025 analysis.
