Stablecoins Shrank for the First Time in Years, Trading Hit $1.79 Trillion

CoinGecko noted that the total stablecoin market cap decreased slightly in the second quarter to $305.1 billion, falling by around $4.8 billion or 1.6%, ending a period of steady upward trend in the market. “Q2 of 2026 was the first recorded quarterly decrease in the market cap of stablecoins since Q3 of 2023”, wrote the company in the Q2 market report.

Much of the damage occurred in June alone. The market lost approximately $7.7 billion in this month, following an ascent to roughly $321-322 billion in the two previous months – the most severe one-month dollar decline since the Luna-Terra collapse in May of 2022, which took an average cumulative loss to roughly $10 billion. CoinDesk Data reported a higher-end total of approximately $312 billion at the end of June, a month-to-date drop of 2.39%. The difference, to be sure, can be seen as a nuance of various tracking methodologies, though everyone agrees on the trendline.

Despite the “biggest drop since Terra” framing, this was a mild contraction in percentage terms, about 3% from peak, versus the 20%+ collapse in 2022 when UST depegged. Neither USDT nor USDC lost their peg in June, as the broader crypto market fared worse, falling 12.6% in Q2 to around $2.1 trillion.

The drop in supply was not uniform across all issuers. Supply for USDC decreased about 4.8% to near $73.5 billion (~$3.7 billion), while USDT remained near flat around $184 billion, raising Tether’s share to approximately 60%. Smaller issuers saw increased market presence in the better-performing climate under the GENIUS Act (USDG from Paxos is at $3.2 billion and USDGO from Anchorage). This centralisation around issuers could signal a risk that may have to be monitored going forward.

In the same month when supply went through its largest decline, the regulated revenue from the transfer of coins operated at its peak of $1.79 trillion in comparison to 63% growth of the previous month and a hefty growth of almost 125% compared to the last year. As stated by CoinDesk and the dashboard by Visa’s Allium, the overall figures for the first half of 2026 make $8.82 trillion.

USDC was responsible for the majority of this volume activity even though it is under half of USDT’s supply. Thus, USDC provided about $1.21 trillion in volume and USDT – $576 billion. It means that USDC tokens exchange hands more often. It is also worth mentioning that the term adjusted volume means that only exchange flows and transactions of DeFi, along with those related to minting and burning, are taken into consideration, and repeats of transfers are eliminated, thus not covering only consumer payments. McKinsey and Artemis conducted a study that showed that the total amount of released stablecoin payments was only around $390 billion throughout 2025. It would be worth noting that on-chain transactions are not the same as real payments.

For about two years, the growth in supply and the increase in usage cycled together. The pattern changed in June 2026. The probable cause for this change is that people are currently using stablecoins differently; instead of storing their funds in stablecoins, the holders now seem to transfer money into and out of stablecoins more quickly and use them as working capital instead of letting their money sit idle.

Probably that surplus cash is going into high-yield tokenized Treasury products instead, given that common stablecoins do not offer interest. RWA.xyz estimates this market to be worth about $16.2 billion, with funds such as Circle USYC and BUIDL holding billions of dollars’ worth of assets. This provides a likely explanation for this capital flight. However, while this appears reasonable, there is no evidence of this kind showing that outflows reached $7.7 billion in these products.

The GENIUS Act, which came into effect in July 2025, has paved the way for the establishment of a federal framework for payment stablecoin providers. The implementation of the OCC regulations, however, is still far from completion at the end of July 2026, with the deadline set for January 2027. Some important pending matters include customer ID proposals (comments are expected till 21 August) as well as new FDIC reporting requirements that can have a huge impact on competition between the USDC-based services in the US and those offered by the USDT-based companies offshore.

Market cap shows us the size of the stablecoin pool, while adjusted volume indicates how quickly it is moving. In June, these figures moved in opposite directions. We saw a significant drop in supply alongside a record level of use. Whether this change is temporary or part of a longer-term trend will depend on upcoming months’ issuance, redemptions, and regulatory clarity.
