Bain & Co: Stablecoin Supply to Grow 12x by 2030

Financial institutions face a compressed timeline to position themselves within emerging stablecoin networks. According to Bain & Company, the supply of these digital cash instruments could grow by as much as 12 times by 2030.

The shift could reshape how capital moves between institutions and across borders. For banks, the question is whether to help define the infrastructure or operate on networks controlled by competitors.

Control over settlement architecture

Ricardo Correia, a partner in Bain & Company's Financial Services practice, frames the issue as one of strategic control. "This is not just about faster payments, it is becoming a strategic question of control over how money moves through the global financial system," he says.

"As stablecoin adoption accelerates, banks are facing a narrowing window to decide where to play."

Correia adds that early movers will help shape emerging settlement networks. Institutions that delay could find themselves operating on infrastructure defined by others.

The research describes this period as a "great rewiring of wholesale banking" where stablecoins and tokenised deposits transition from experimental tools to core infrastructure.

Corporate demand for efficiency

Cross-border complexity creates friction for multinational operations. According to Bain & Company, 34% of CFOs identify this as a leading challenge.

Fragmented foreign exchange markets, delayed settlement cycles and the requirement for pre-funded accounts all add operational cost. Stablecoins and tokenised deposits offer near-instant, programmable transfers that can operate continuously across time zones.

The ability to reduce delays and enable faster reuse of capital could unlock trapped liquidity. This could improve capital efficiency and reduce operational complexity for financial institutions.

Use cases are already appearing in foreign exchange, collateral management and corporate treasury operations. Speed, programmability and continuous availability offer advantages over legacy systems in these areas.

Regulatory and operational barriers

Bain & Company identifies sanctions screening and transaction monitoring as key barriers to adoption. These challenges are particularly acute in cross-border contexts.

The firm recommends a phased approach. Pilot programmes and targeted deployments should precede broader participation in emerging networks.

Institutions must also invest in compliance frameworks, data integration and operational infrastructure to support adoption. These foundations are necessary before scaling participation.

The report draws attention to high-friction areas where digital money can deliver tangible improvements. Cross-border foreign exchange, collateral management and treasury functions present the clearest opportunities.

Two-system operating model

Bain & Company does not anticipate stablecoins replacing traditional banking infrastructure. Instead, the firm describes a "two rails, one system" model where digital and traditional financial systems operate in parallel.

This approach will require banks to embed digital asset custody into existing risk frameworks. Institutions must also invest in blockchain connectivity and real-time reconciliation between on-chain transactions and internal ledgers.

Capital should move seamlessly between the two systems. The ability to do so could determine competitive positioning as adoption scales.

"As stablecoin supply and use scales, institutions' early participation in these networks will increasingly determine where value accrues in the next generation of wholesale banking," Correia says.

Strategic window closes

The research makes clear that stablecoins have moved from the periphery of the financial system. As adoption accelerates and supply expands, they are positioned to play a central role in wholesale banking.

For financial institutions, the opportunity and urgency are both substantial. Those that move early will not only capture efficiency gains but also help define the infrastructure that underpins global finance for years to come.

The decision to participate is becoming less about technology experimentation and more about competitive positioning. The window to influence network design is finite.
