How regulatory shifts permanently reshaped the digital dollar economy, sparked an RWA boom, and accelerated the transition to B2B payments.
For the first time in four years, the global stablecoin market has experienced a significant contraction. According to DeFiLlama, by July 28, 2026, the overall market capitalization of “stablecoins” dropped to around $310 billion, declining by over $10 billion from its May peak. The industry hasn’t seen a net capital outflow of this scale since the collapse of the Terra ecosystem in May 2022.
However, behind this shrinking supply lies a major paradox: actual usage of digital dollars has hit an all-time high. In June 2026, the adjusted transfer volume of stablecoins grew by 63% month-over-month, reaching an unprecedented $1.79 trillion.
The GENIUS Act Effect: Where Is Liquidity Going?
The key driver behind the disconnect between falling market cap and surging transfer volumes was the passage of the GENIUS Act in July 2025. U.S. lawmakers introduced a strict ban prohibiting issuers of payment stablecoins from paying interest yield to holders.
Marquette University finance professor David Krause commented on the impact of this rule:
“The difficulty is that the ban didn’t destroy the underlying demand for yield — it merely displaced it. Investors looking for a digital dollar with a yield close to the U.S. Treasury bill rate simply found other products legally allowed to offer it. The [GENIUS Act] rule, intended to protect banks and maintain monetary control, instead pushed capital into instruments that regulators understand less and control less strictly.”
The ban fundamentally altered capital mechanics. CFOs and institutional investors restructured their treasury operations: they now store the bulk of their liquidity in tokenized funds yielding around 4% annually, acquiring stablecoins only briefly when needed to execute specific payments. As a result, money no longer sits idle on balance sheets, but velocity speeds up — turnover rises while permanent stablecoin capitalization drops.
The RWA Boom and New Market Leaders
Freed-up capital surged into the Real World Assets (RWA) sector — primarily tokenized U.S. Treasury bond funds. In just five months, total assets in this sector jumped from $11 billion to $16 billion.
According to data from RWA.xyz, this reallocation led to a shakeup among top players:
- Circle’s USYC fund surpassed the former leader, BlackRock’s BUIDL, in volume.
- A similar tokenized product from JPMorgan surged by 87% in a single month.
Clash of the Titans: USDC vs. USDT
The acceleration of capital velocity dramatically shifted the balance of power among leading issuers. In Q4 2025, Visa estimated the velocity of stablecoins reached 13.56 — outpacing the traditional M1 money supply (1.65) nearly eightfold.
In this high-velocity environment, USDC became the primary choice for institutional players. According to Visa and Allium, USDC accounted for roughly 70% of all transactions in the first half of 2026.
By the end of June 2026, transaction volume breakdowns were as follows:
- USDC: $1.21 trillion (~67.6% market share).
- USDT: $576 billion (~32% market share).
Despite lagging behind USDC in transfer volume by more than half, Tether (USDT) maintains an undisputed lead in total market capitalization. It continues to serve as a reliable digital “savings account” for users in emerging markets.
Transformation of the Industry’s Business Model
Falling market cap alongside record-breaking utility signals a profound transformation across the crypto industry:
- A blow to the traditional issuer model. Earning revenue solely from interest on underlying reserve assets — the bedrock business model of 2021 — is no longer the primary financial driver for the sector.
- Triumph of infrastructure players. Primary revenue flows are shifting toward payment networks, processors, and blockchains that capture transaction fees. Payment giants like Visa no longer evaluate the market by total locked asset value, focusing instead purely on clearing volumes.
- Dominance of the B2B sector. A study by McKinsey and Artemis reveals that in 2025, identifiable real-world payments reached approximately $390 billion (with $226 billion stemming from the B2B sector). Although this represents only about 1% of total network volume, it marks a 30-fold increase compared to data from two years prior.
The global stablecoin market is maturing, permanently evolving from a speculative trading tool into a high-speed financial highway for international corporate settlements and tokenized real-world assets.
