Stablecoins Are Starting to Reshape Payments and Banking, Macquarie Says

Stablecoins are increasingly being viewed as a foundational layer of global financial infrastructure, according to Macquarie. The trend is driven by growing institutional adoption and regulatory advancements that are helping move stablecoins from speculative trading tools toward practical use in payments and settlement.

The rise of stablecoins is evident in their expanding market size and transaction volume. As of March 2026, the combined market capitalization of major stablecoins has reached approximately $312 billion, up roughly 50% from a year earlier. Adjusted stablecoin transfer volume reached about $11 trillion in 2025, signaling the growing economic significance of onchain dollars.

The integration of stablecoins into mainstream financial systems is accelerating. Visa and Mastercard now support USDC for settlement, allowing card obligations to be discharged onchain. Banks like JPMorgan and Citi are also exploring tokenized deposit products and similar initiatives.

Why Is Institutional Adoption of Stablecoins Growing?

Enterprises are increasingly using USDC for treasury management due to its speed, cost-effectiveness, and compliance features. The stablecoin allows companies to reduce settlement times and costs, automate payments, and maintain control over their liquidity across multiple blockchain networks.

USDC's multi-chain presence on Ethereum, Solana, Avalanche, and Polygon enables strategic liquidity distribution across regions, reducing settlement friction and slippage. Companies are also integrating USDC with enterprise software like Salesforce to automate payment workflows and maintain audit trails.

How Are Stablecoins Reshaping Financial Infrastructure?

Stablecoins are not only supporting payments but also transforming remittance and cross-border transactions. In Africa, for instance, demand for stablecoins is driven by the need to hedge against currency volatility and the high costs of traditional money transfers. Stablecoins offer faster and cheaper alternatives to traditional remittance services, which often charge about $6 for every $100 sent.

Financial institutions are also exploring stablecoin integration for digital supply chain finance and international transactions. Woori Financial Group is one such institution reviewing ways to use stablecoins in cross-border payments and supply chain finance, potentially automating payments with smart contracts to improve transparency and speed.

KAST, a stablecoin-based financial platform, has raised $80 million in a Series A round, led by QED Investors and Left Lane Capital. The platform provides USD-denominated accounts and global payment capabilities built on stablecoin technology. With over one million users and $5 billion in annualized transaction volume, KAST is expanding into Latin America, North America, and the Middle East to serve individuals and businesses left behind by the traditional banking system.

What Drives the Expansion of Stablecoin Usage in Global Markets?

Regulatory progress is a key enabler of stablecoin adoption. Developments such as the U.S. GENIUS Act, Europe's MiCA framework, and emerging Asia-Pacific regulations are pushing stablecoins from speculative uses toward institutional settlement tools.

USDC, a major stablecoin, is fully backed by U.S. dollars and short-term U.S. Treasuries. It operates on 28 blockchain networks and is transparent through monthly audits and third-party reporting. The SEC confirmed in April 2025 that USDC is not a security, supporting its role as a regulated financial instrument.

As stablecoins continue to gain traction, they are becoming an essential part of the global financial system. Their use is expanding from trading and remittances to treasury operations, corporate finance, and institutional settlement. With more financial institutions and enterprises adopting stablecoins, onchain dollars are reshaping the future of finance.
