Speaking on March 12, Patrick Witt said that stablecoins meeting the requirements of the GENIUS Act will "actually lead to deposit inflows" into the US banking system. The statement challenges the framing of an ongoing policy dispute in which major US banks have warned that stablecoins bearing yields could trigger an estimated $6.6 trillion outflow from traditional deposits.

The Regulation Behind the Argument

The GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins) was signed into law by President Trump on July 18, 2025, after passing the Senate 68 to 30 and the House 308 to 122. The law requires all payment stablecoins to maintain 1:1 reserve backing, with reserves held exclusively in US Treasuries, cash, or approved low-risk instruments. Crucially, it prohibits issuers from lending out or rehypothecating those reserves. Regulatory implementation deadlines fall on July 18, 2026.

The logic behind Witt's deposit inflow claim runs as follows. As global demand for dollar-denominated stablecoins grows, issuers must purchase US Treasuries to back every unit in circulation. Tether, currently the largest stablecoin issuer with a market cap above $150 billion, already held approximately $135 billion in US debt instruments (direct and indirect) as of December 2025, according to the company's attestation reports, with Treasuries comprising more than 83% of its reserves according to a January 2026 Stablecoin Insider reserves report.

That figure puts Tether's Treasury holdings above those of Germany and Israel, placing it roughly 17th among all global holders of US government debt. It is important to note, however, that Tether is not a GENIUS Act-compliant entity. Tether is domiciled offshore, in El Salvador and the British Virgin Islands, and had not registered as a GENIUS-compliant issuer as of this article's publication date. Tether's reserve behavior resembles what the GENIUS Act mandates for compliant issuers, but Tether itself does not operate under that framework. The figures above illustrate the potential scale of the mechanism Witt describes; they do not reflect a GENIUS Act outcome.

The total stablecoin market now sits at approximately $312 billion, up roughly 50% year over year, according to DefiLlama data and analysis from Macquarie published this week. Transaction volume across stablecoin networks reached around $33 trillion in 2025, according to Stablecoin Insider, with adjusted transfer volume estimated at $11 trillion, a figure that strips out automated and non-economic transactions, per Macquarie and CoinDesk analysis.

The Dimon Dispute

Witt's comments are a direct response to JPMorgan CEO Jamie Dimon, who has argued that any platform holding balances and paying interest is functionally a bank and should face equivalent capital and insurance requirements. "If you are going to be holding balances and paying interest, that's the bank. You should be regulated by a bank," Dimon said, according to CoinDesk.

Witt rejected that framing earlier this month: "The deceit here is that it is not the paying of yield on a balance per se that necessitates bank-like regulations, but rather the lending out or rehypothecation of the dollars that make up the underlying balance." Because GENIUS-compliant issuers cannot lend out reserves, Witt argues the bank-equivalence claim does not hold.

A White House meeting with major banks in February reportedly signaled that the administration supports certain stablecoin yield mechanisms and expects banks to adapt rather than resist stablecoin growth.

What This Means Outside the United States

For users in Nigeria, India, and across Sub-Saharan Africa, the policy debate in Washington has concrete financial consequences.

Stablecoins account for 43% of all crypto transaction volume across Africa, according to AFI Global. In Nigeria specifically, stablecoin transaction volume reached approximately $22 billion in the 12-month period from July 2023 to June 2024, according to TRM Labs and Web3 Enabler data. Much of that activity involves USDT and USDC used for savings protection against local currency devaluation and for cross-border remittances, though publicly available data does not break down Nigerian stablecoin activity by specific use case.

For everyday users, the connection between stablecoin activity and US Treasury demand is already visible. A Nigerian trader buying USDT routes capital into Tether's reserve structure, which is currently composed primarily of US Treasuries. An Indian freelancer holding USDC between client payments routes capital through Circle's reserves, which operate under US regulatory oversight. Both activities tie global dollar demand to American debt markets, though only USDC, issued by the US-regulated Circle, represents the model the GENIUS Act formalizes. This appears to be the structural dynamic that Witt's policy argument describes and that the GENIUS Act is designed to institutionalize at scale.

The Alliance for Financial Inclusion has named the risk directly, noting that dollar stablecoins contribute to dollarization and can weaken monetary policy transmission in emerging economies.

India currently has no stablecoin-specific regulatory framework. The Reserve Bank of India has repeatedly favored its own central bank digital currency (the e-Rupee) over private stablecoins, with the RBI Governor warning in October 2025 about threats to monetary sovereignty. India's Economic Survey 2025-2026 has signaled that a domestic stablecoin regulatory framework may be forthcoming, suggesting Indian regulators are beginning to address the question. For now, a regulatory vacuum means GENIUS-compliant US stablecoins may become entrenched infrastructure before domestic rules are fully in place.

Looking Ahead

Macquarie analysts noted this week that stablecoins are transitioning from speculative instruments to institutional settlement tools, with Visa, Mastercard, Citibank, HSBC, and JPMorgan (through its JPMD tokenized deposit product) all integrating stablecoin or tokenized deposit infrastructure.

Western Union announced USDPT on Solana in late 2025, targeting remittance corridors into Africa and Asia, with the commercial rollout planned for 2026.

The next major regulatory deadline is July 18, 2026, one year after the GENIUS Act's enactment, with the FDIC having already proposed application procedures for supervised institutions. Rulemaking from that process will determine custody and compliance requirements that affect both US banks offering stablecoin products and international fintechs building on dollar stablecoin rails. US Treasury Secretary Scott Bessent has framed the GENIUS Act explicitly as a tool to reinforce US dollar primacy in global finance, lending direct policy weight to Witt's argument. The World Economic Forum projects the total stablecoin market could reach $2 trillion by 2028. If that growth materializes under the current reserve framework, the structural dynamic Witt described will scale accordingly, regardless of whether emerging market regulators have caught up.
