Stablecoins Surge to 60% of Crypto On-Ramp Volume — Mercuryo's H1 2026 Data Shows the Digital Dollar Has Won

In just six months, stablecoins have crossed from a complementary asset class into the dominant medium for both entering and exiting the crypto economy. New data from payments infrastructure platform Mercuryo shows that in the first half of 2026, stablecoins accounted for 60% of total crypto purchase value on its on-ramp infrastructure, up from 43% in the second half of 2025 . The shift is even more pronounced among newcomers: 47% of first-time crypto buyers now start with a stablecoin, and on the exit side, stablecoins represent 57% of all off-ramp transactions — more than double the 25% share from a year earlier . This is not a temporary rotation driven by market volatility. The data points to a structural shift: stablecoins are becoming a core payments and settlement layer, increasingly used for payroll, remittances, treasury management, and everyday digital payments, supported by deep infrastructure from card networks and emerging regulatory frameworks like the GENIUS Act.

How Stablecoins Took Over the On-Ramp

Mercuryo's on-ramp data, comparing H1 2026 to H2 2025, reveals a decisive shift in crypto buying behavior.

Nearly $6 of every $10 on-ramped went into stablecoins in H1 2026 . Every other major asset class lost share: Ethereum dropped from 19.5% to 13.3%, Bitcoin fell from 16.1% to 12.6%, and all other assets combined declined from 21.4% to 14.5% .

First-time buyers are driving much of this growth. Stablecoins accounted for 47% of first purchases, up from 33% in H2 2025 — meaning nearly every second new crypto user now starts with a digital dollar . The trend accelerated even as the total crypto market cap fell roughly 30% (from $2.96T to $2.08T), suggesting users are actively rotating into stablecoins as a lower-volatility haven rather than simply exiting crypto altogether .

Average order sizes also tell the story: stablecoin orders grew 28% half-over-half, while Bitcoin's average order shrank ~6% and other assets dropped 10%. Overall average purchase size grew 16% .

The Off-Ramp Mirror: Stablecoins Now Lead the Exit Too

The off-ramp data — converting crypto back to fiat — shows the same transformation, only faster.

In H1 2026, stablecoins accounted for 57% of all accepted off-ramp transactions, up from 25% a year earlier . Their share of off-ramp turnover (value) rose from 30% to 56% — essentially doubling .

The volume growth is staggering: stablecoin off-ramp transaction volumes rose 446% year-on-year, compared to just 38% growth for other crypto tokens. Stablecoins contributed roughly 80% of total off-ramp growth .

Weekend cash-out behavior reinforces the utility thesis: weekend off-ramp volumes averaged about 86% of weekday levels, reflecting demand for always-on access to cash outside traditional banking hours .

What's Driving the Shift: Five Key Factors

1. Crypto Payroll Is Going Mainstream

Rise's 2025 Crypto Payroll Report found that 25% of businesses already use crypto for payroll . Rise has processed over $1 billion in payroll volume, with more than half of worker withdrawals now in stablecoins across 190+ countries . Global payroll provider Deel is also building stablecoin payroll infrastructure, signaling that crypto salary payment is moving from niche to normal .

2. Brazil as a Stablecoin Hotspot

Brazil received an estimated $318.8 billion in crypto value between July 2024 and June 2025, with roughly 90% of flows linked to stablecoins, according to Chainalysis data and Brazilian central-bank commentary . This massive inflow is driven by use cases like cross-border trade settlement, remittances, and savings in an inflationary environment.

3. Real-World Payment Use Cases Expand

Neobanks are integrating stablecoin rails for international transfers. Businesses increasingly use stablecoins for treasury rebalancing, working capital movement, and real-time supplier settlement — all benefiting from 24/7 settlement that bypasses traditional banking hours .

4. Visa and Mastercard Deepen Stablecoin Infrastructure

Visa has expanded stablecoin settlement capabilities (USDC over Solana and Ethereum), introduced stablecoin payouts for creators and freelancers, and continues to build payment rails that treat stablecoins as a first-class settlement asset . These integrations lower the friction for both consumers and businesses to use stablecoins in everyday transactions.

5. Regulatory Momentum: The GENIUS Act

The GENIUS Act in the United States outlined a legal framework for stablecoin issuance, reserve backing, and consumer protections . While still evolving, the legislation is expected to strengthen institutional confidence and accelerate adoption of regulated stablecoins by providing clearer rules of the road.

Broader Significance: Stablecoins as the New Payments Layer

The Mercuryo data marks a clear inflection point. Stablecoins are no longer just a trading safe harbor or a vehicle for DeFi yield farming. They are becoming a core payments and settlement layer for the digital economy — used for payroll, cross-border remittances, treasury management, supplier payments, and everyday digital purchases.

The combination of utility-driven demand (especially from crypto payroll), card network integrations, and improving regulatory clarity points to continued growth in H2 2026 and beyond. As stablecoins make up the majority of both on-ramp and off-ramp activity, they increasingly serve as the bridge between traditional finance and the crypto economy — not a side asset class, but the main channel itself.
