Two ways to move dollars internationally
Both SWIFT and stablecoins move value across borders, but they do it very differently. A SWIFT transfer sends messages between banks, which then move money through a chain of correspondent institutions (see how SWIFT works). Every bank in that chain can introduce fees, delays, compliance reviews and operating-hour limits. A stablecoin transfer moves a dollar-pegged digital asset such as USDC or USDT directly on a blockchain network, settles 24/7 and needs no intermediary banks. The difference is like taking a flight with multiple layovers versus flying direct.
Why SWIFT transfers are slow and expensive
- Correspondent banks each add cost.
- Banks operate in different time zones.
- Compliance reviews can create delays.
- Transfers pause on weekends and holidays.
- The recipient may receive less than was sent, after intermediary fees.
Why stablecoin rails are growing
- Settlement in seconds or minutes.
- Availability around the clock, 24/7.
- Transparent, on-chain tracking.
- Lower operating costs.
- Global accessibility.
The IOF difference
For Brazilians, the difference that matters most is often tax. A traditional SWIFT transfer sent abroad can carry up to 3.5% IOF under current rules (Decreto 12.499/2025), before FX spreads and Wire fees. A stablecoin transfer does not use traditional correspondent-bank foreign-exchange rails, so under current regulation it is not a câmbio operation and that IOF does not apply. The result is often a dramatically lower total cost. You can check the real numbers in how much IOF you pay.
When SWIFT still makes sense
- Large institutional settlements.
- Counterparties that only accept bank Wires.
- Certain currencies and jurisdictions.
- Traditional banking workflows.
How Ruvo moves money
Ruvo does not force every transfer onto a single rail. It combines multiple payment networks and uses the most efficient route available. In the US, Ruvo supports ACH, RTP (Real-Time Payments) and domestic Wires; in Brazil, it supports Pix; for digital-dollar settlement it uses stablecoin rails; and you can send and receive crypto directly. SWIFT support will be added for customers who need traditional international Wires. The key point: a full end-to-end SWIFT transfer, from a US bank account to a Brazilian one or back, is usually slower and more expensive than routing through local rails and stablecoin settlement. Receiving dollars is free, converting to reais is 0.3% for businesses (0.9% for individuals), and there is 0% IOF throughout. The same rail powers cross-border stablecoin remittances.
The future is hybrid
Cross-border payments are unlikely to be purely SWIFT or purely crypto. The winning approach combines local payment rails such as ACH and RTP, stablecoin settlement for global movement (see ACH vs SWIFT for a full comparison), and traditional banking rails where they are still needed. That mix minimizes fees, shortens settlement times and gives you more flexibility than relying on any single network.
