Bain Projects 5x To 12x Stablecoin Supply Growth By 2030 As Banks Rewire Wholesale Rails

The global supply of stablecoins is projected to grow by up to 12-fold by 2030, according to a new report from @BainandCompany released today. In a shift the firm calls an emerging "great rewiring of wholesale banking," Bain finds that stablecoins and tokenized deposits have moved from mainly speculative instruments to strategic liquidity tools for banks — and that the question for institutions is no longer whether they matter, but where to move first.

Cross-Border Friction Drives the Case for On-Chain Settlement

Inefficiencies in global money movement remain widespread. Fragmented foreign exchange markets, settlement delays, and pre-funding requirements continue to constrain capital flows across the financial system, creating a structural opening for stablecoins that operate around the clock and move instantly across borders. Bain's research among chief financial officers found that 34% cited cross-border complexity as a leading pain point, with FX settlement, derivatives margining, and corporate treasury operations identified as the highest-friction use cases ripe for disruption.

The scale of the FX market underscores the opportunity. According to the Bank for International Settlements' 2025 Triennial Central Bank Survey, trading in OTC FX markets reached $9.6 trillion per day in April 2025, up 28% from 2022. Bain argues that programmable on-chain settlement can compress the principal risk exposure windows that persist in that market — particularly for emerging market currency pairs, non-CLS participants, and off-hours trades. Several bank-led platforms already process billions in daily on-chain wholesale payments.

Compliance First, Issuance Later

Bain's recommended sequence for banks is clear: accept stablecoins first, then run targeted pilots in FX corridors and collateral workflows, and consider proprietary issuance only if scale justifies it. The firm identifies compliance integration — not transaction speed — as the decisive factor determining which banks scale fastest. Sanctions screening, transaction monitoring, and data infrastructure are flagged as priority investments, with regulatory and operational hurdles remaining the key barriers to broader adoption.

"This is not just about faster payments, it is becoming a strategic question of control over how money moves through the global financial system," said Ricardo Correia, a partner in Bain's Financial Services practice. The firm warns that banks delaying engagement risk ceding ground and ultimately participating on terms set by earlier movers.
