Stablecoin Market loses $7.7B as Blockchain Transactions Hit Record Highs

The global stablecoin market contracted in June for the first time in five months, even as blockchain transaction volumes climbed to record highs, signaling a widening gap between the amount of stablecoins in circulation and how actively they are being used.

According to CoinDesk Data, the total stablecoin market capitalization fell by 2.39%, or approximately $7.7 billion, to $312 billion in June. It marked the largest monthly decline in dollar terms since the collapse of the Terra-Luna ecosystem in 2022, although the scale of the decline was far less severe.

On-Chain Activity Climbs to Record Levels

While the overall supply of stablecoins declined, blockchain activity continued to accelerate.

Data from Visa's Stablecoin Dashboard, powered by Allium, showed that adjusted stablecoin transaction volume reached $1.79 trillion in June. That represents a 63% increase from May and a 125% jump compared with June 2025, underscoring continued demand for stablecoins across blockchain networks.

Perhaps most notably, USD Coin (USDC) processed approximately $1.21 trillion in adjusted transaction volume during the month, significantly outperforming Tether's USDT, which recorded around $576 billion despite remaining the largest stablecoin by market capitalization.

By late July, the stablecoin market had declined further. DefiLlama data showed total stablecoin market capitalization at approximately $309.9 billion on July 28, down 0.79% over the previous 30 days. USDT continued to dominate the sector with a market capitalization of roughly $183.9 billion, while USDC stood at approximately $73.7 billion.

Not Another Terra Moment

Although June represented the largest monthly decline in dollar value since Terra's collapse, analysts caution against drawing direct comparisons.

Unlike the 2022 crisis, the recent contraction was driven primarily by a reduction in circulating supply rather than a loss of confidence in stablecoins themselves.

During the second quarter of 2022, major stablecoins collectively lost around $33.9 billion, nearly one-fifth of their total market value, following the collapse of TerraUSD (UST) and the broader crypto credit crisis, according to CoinGecko.

In contrast, leading stablecoins such as USDT and USDC maintained their peg close to $1 throughout the recent decline, indicating that the market remained stable despite shrinking supply.

Different Data Providers Paint Different Pictures

Measuring the stablecoin market is not always straightforward, as different analytics firms apply varying methodologies and asset classifications.

CoinDesk estimated the market at $312 billion at the end of June, while CoinGecko's second-quarter report placed total stablecoin capitalization at $305.1 billion, representing a quarterly decline of $4.8 billion, or 1.6%.

CoinGecko described the quarter as the first quarterly contraction since the third quarter of 2023, whereas CoinDesk identified June as the first monthly decline after five consecutive months of growth.

Although both datasets point to a market contraction, they do not support claims that the stablecoin market has experienced its first decline of any kind since the Terra collapse.

Record Transaction Volume Doesn't Mean Record Payments

The record $1.79 trillion in adjusted transaction volume should not be interpreted as an equivalent amount of real-world payments.

Visa's methodology filters out activity considered non-economic, including known bot transactions, exchange internal transfers, repetitive smart contract interactions, and unusually large or highly active wallets. It also counts only the largest stablecoin transfer within complex transactions to reduce double counting.

Even after these adjustments, the figures still include exchange deposits and withdrawals, decentralized exchange trading, lending activity, investment funds, minting and burning events, and cross-chain transfers.

As a result, the adjusted transaction volume reflects filtered economic activity on blockchain networks rather than consumer purchases or merchant settlements.

The data also highlights differing usage patterns among stablecoins. Despite having less than half of USDT's circulating supply, USDC generated more than twice the adjusted transaction volume, suggesting a significantly higher turnover rate.

This indicates that transaction volume depends not only on the number of tokens in circulation but also on how frequently they move across blockchain networks.

Blockchain Activity and Payments Remain Different Metrics

A separate analysis by McKinsey & Company and Artemis further illustrates the distinction between blockchain activity and actual payment adoption.

The firms estimated identifiable stablecoin payments totaled approximately $390 billion during 2025, representing only around 0.02% of global payment volumes.

Business-to-business (B2B) payments accounted for roughly $226 billion, while much of the remaining blockchain activity stemmed from trading, internal wallet transfers, and automated transactions.

The findings suggest that growing blockchain transaction volumes do not necessarily indicate widespread adoption of stablecoins for everyday commercial payments.

Yield-Bearing Tokenized Assets Gain Attention

The decline in non-yielding stablecoins is also drawing attention to tokenized real-world assets, particularly blockchain-based U.S. Treasury products that offer investors exposure to government debt while generating returns.

According to RWA.xyz, tokenized U.S. Treasury products were valued at approximately $16.2 billion by late July.

DefiLlama data showed that Circle's USYC fund managed roughly $3 billion in assets as of July 28, while BlackRock's BUIDL fund held approximately $2.64 billion.

Unlike traditional stablecoins, which are designed to maintain a fixed value without passing reserve yields to holders, tokenized Treasury products allow investors to earn returns while keeping assets on blockchain networks.

This has fueled speculation that some capital could gradually shift from stablecoins into yield-generating digital assets before being converted back into stablecoins for settlement purposes.

No Evidence of a Direct Capital Migration

Despite that economic rationale, current data does not support the conclusion that the entire $7.7 billion reduction in stablecoin supply flowed directly into tokenized Treasury products.

While CoinDesk reported that the broader tokenized real-world asset market grew 1.75% in June to $30.1 billion, the source of new capital remains unclear. Funds could have moved into traditional bank accounts, other crypto assets, or different investment vehicles altogether.

CoinGecko also found that several yield-bearing digital assets declined during the second quarter. USDS fell 16.4%, while USDe dropped 24.4%, partly reflecting lower yields relative to risk-free interest rates and investor withdrawals.

Taken together, the data points to a selective reallocation of capital rather than a broad migration away from stablecoins.

As the market continues to evolve, June's figures suggest that circulating supply alone no longer tells the full story. Stablecoin usage is becoming increasingly defined by transaction velocity and infrastructure activity, while tokenized yield-bearing assets are emerging as a complementary segment of the digital asset ecosystem rather than a direct replacement.
