Stablecoins are rewriting financial history: How digital dollars are challenging the ACH system

The era of digital payments has long begun – not as a distant vision, but as a tangible reality. Stablecoins like USDT and USDC have evolved from mere crypto instruments to serious competitors of the established payment infrastructure. With a combined market capitalization of over $384 billion, they are increasingly penetrating the core of the American financial system: the ACH network.

The Numbers Tell a Clear Story

The significance of this development becomes evident through concrete metrics. Stablecoins already generate about half of the ACH transaction volume and significantly surpass established payment networks like Visa in their on-chain activities. Notably: USDC alone has a current market capitalization of $75.42 billion. If the current growth rate continues – according to projections by Galaxy Digital – the total stablecoin volume could surpass traditional ACH by 2026.

Efficiency Beats Tradition

The key advantage lies not only in the numbers but in the fundamental way they operate. While the traditional ACH system is tied to business days and transactions can take up to 48 hours, stablecoins operate 24/7 with nearly instant transfers. Additionally: The fee structure is considerably more transparent and cheaper. This efficiency edge is already prompting established institutions to act: Visa is integrating USDC for billing processes, and traditional banks are actively experimenting with their own tokenized currencies.

A Transformation with Deep Impact

This does not mean that the conventional banking system will become obsolete tomorrow. Rather, we are witnessing a fundamental restructuring of money flows: payments are becoming faster, programmable, and inherently global. With emerging regulatory clarifications, this market could grow exponentially. The central question has shifted – no longer if digital dollars will transform the financial system, but how far this revolution will reach and how quickly it will advance.
