Bain: $320B Stablecoin Market Could Rewire Wholesale Banks

Bain & Company published a report on April 29 that says stablecoins and tokenized deposits are moving from speculative instruments to practical tools for wholesale payments. The report, “From Hype to Hard Value: Stablecoin and the Great Rewiring of Wholesale Banking,” was authored by a six-person team including Ricardo Correia, Karim Ahmad and Philipp Grimmig.

The report identifies persistent frictions in traditional banking that it says stablecoins can address. Cross-border payments are described as slow, collateral management ties up billions in idle capital, and corporate treasury operations run on fragmented systems across jurisdictions. Bain describes stablecoins as “always-on” and programmable, allowing transactions to settle instantly and reducing the number of intermediaries involved in money movement.

Bain recommends that wholesale banks and large corporations prioritize stablecoins and tokenized deposits in their strategic planning. Operational priorities listed in the report include integrating stablecoin payment rails with existing systems, meeting regulatory requirements, and building processes for foreign-exchange settlement, derivatives collateral management and corporate treasury liquidity.

Regulatory clarity is presented as a constraint on scaling the changes Bain outlines. The CLARITY Act, which would set rules on whether digital assets are securities or commodities, has not advanced in committee. Sen. Thom Tillis has sought a committee vote and is planning to release final legislative text a few days before any vote, but negotiations have delayed the timetable. The report notes that if the committee does not act by mid-May, the bill’s chance of passing this year falls sharply because of the election calendar.

The report also notes the GENIUS Act, which focuses specifically on stablecoin rules, is moving through committee. Lobbying is active: representatives of traditional banks have opposed provisions that would allow platforms to offer interest on stablecoins, arguing those rules could shift deposits and liquidity out of the banking system. A White House paper published in April judged that risk as smaller.

Market data cited in the report put the stablecoin sector’s total market capitalization at about $320 billion, based on DefiLlama figures. The report concludes that without clearer rules and operational integration, the broad “rewiring” of wholesale banking it describes cannot occur at scale.
