The total stablecoin market cap grew by $931.4 million over the week of August 3-9, according to on-chain analytics firm Lookonchain's weekly report, even as spot DEX volume and perpetuals volume both declined over the same period. Public companies tracked in the report collectively shed 66 BTC from their treasuries during the week, a modest but continued drift away from the aggressive accumulation many corporate treasuries pursued earlier in the cycle.
The stablecoin growth fits a broader 2026 trend: total stablecoin supply has expanded from roughly $161 billion in mid-2024 to around $313-316 billion by mid-2026, a roughly 23% year-over-year increase, with Citigroup and US Treasury Secretary Scott Bessent projecting the market could reach $420 billion before year-end. Tether's USDT and Circle's USDC together account for about 83% of that supply, with USDT alone holding roughly 59% of the market.
Liquidity growing while trading activity cools
The divergence Lookonchain's report highlights, rising stablecoin supply against falling exchange trading volume, is a pattern worth watching closely. Growing stablecoin issuance typically reflects capital entering the crypto ecosystem or being held in reserve, while declining DEX and perpetuals volume suggests that capital isn't being immediately deployed into active trading. That combination has historically preceded periods of either accumulation ahead of a move, or simple risk-off caution as traders wait for clearer signals.
The 66 BTC reduction in public company treasuries recorded for the week is smaller than the standalone sales disclosed individually by companies like MARA and Strategy this earnings season, suggesting the aggregate weekly figure nets out continued accumulation by some corporate holders against disposals by others rather than reflecting uniform selling across the sector.

Why the stablecoin trend matters
Stablecoin supply is widely used as a proxy for dry powder sitting on the sidelines of crypto markets, since USDT and USDC balances often represent capital that has already converted from fiat and is positioned to move into other assets quickly. A $931.4 million weekly increase, while modest relative to the roughly $313 billion total market, adds to a growth trajectory that, if it holds through year-end, would represent one of the fastest expansions in stablecoin supply since the sector's post-2022 recovery.
Whether that growing liquidity translates into renewed trading activity or continues to sit idle will likely depend on the same macro catalysts, including US rate policy and geopolitical developments, that have been driving volatility in both crypto and traditional markets through August.
