The GENIUS Act has turned dollar-backed stablecoins into a geopolitical tool, cementing US monetary dominance through digital rails. We examine how banks, fintechs, and the global financial order are adapting.President Trump signed the Guiding and Establishing National Innovation for US Stablecoins Act — the GENIUS Act — into law, calling it a “giant step to cement American dominance of global finance and crypto technology.” The statement was remarkable for its candour. While most financial regulation is framed in terms of consumer protection and market stability, the GENIUS Act was openly instrumental: a mechanism to extend the dollar’s reach into digital payment infrastructure before competitors could establish alternatives.

Eighteen months on, its consequences are reshaping the global payments landscape in ways that traditional finance and emerging market central banks are still absorbing.

The Regulatory Architecture: What the GENIUS Act Actually Does

At its core, the GENIUS Act defines payment stablecoins as payment instruments rather than securities or commodities, resolving years of legal ambiguity that had prevented major banks and fintechs from fully entering the market. Issuers must maintain 1:1 reserves in high-quality liquid assets — US dollars, short-term Treasuries, or equivalent instruments — and publicly disclose reserve compositions monthly. Larger issuers must submit to annual audits.

The result is a structural demand mechanism for US government paper. Stablecoin issuers’ reserve requirements effectively create a new and growing buyer class for Treasury securities and bills, with some reserve structures potentially channelling demand into longer-duration instruments through repurchase agreement collateral chains. The Brookings Institution has noted that this linkage could function as a subtle fiscal instrument — reducing Treasury funding costs while simultaneously globalising dollar-denominated digital cash.

The two largest stablecoins now carry a combined market capitalisation of $260 billion — three times their 2023 value, according to IMF data. Tether’s USDT alone stands at more than $180 billion in circulating supply. USDC and PayPal’s PYUSD are the regulated challengers competing for the US market share that the GENIUS Act’s framework favours.

The Payments Revolution: Numbers That Reframe the Discussion

The stablecoin market’s scale is already beyond casual classification. In 2024, stablecoin transfer volume surged to $27.6 trillion — more than the combined transaction volume of Visa and Mastercard. The GENIUS Act’s legal clarity has accelerated institutional adoption further: stablecoins are expected to represent 3% of all US dollar payments in 2026, rising to 10% by 2031. A major payment processor has debuted stablecoin payments for subscriptions. Credit card companies have launched fiat-to-stablecoin payout options.

For cross-border B2B payments — historically the most friction-laden segment of global finance, characterised by multi-day settlement times, correspondent banking chains, and 2-5% transaction costs — stablecoins offer near-instantaneous, around-the-clock settlement at dramatically lower cost. This makes them particularly powerful for trade finance in emerging markets and for remittance flows, which the World Bank estimates still cost an average of 6% globally.

The Geopolitical Stakes: Dollar Dominance 2.0

The GENIUS Act’s deepest purpose is not financial regulation. It is currency geopolitics. More than 99% of stablecoins’ value is pegged to the dollar rather than other currencies, creating a form of dollar-denominated digital cash that circulates globally, 24 hours a day, on blockchain rails that bypass traditional correspondent banking infrastructure. Countries seeking to transact outside the SWIFT system, or to reduce exposure to US sanctions architecture, find that dollar stablecoins — ironically — extend US monetary reach further, not less, by embedding the dollar into decentralised financial protocols.

The European Union’s MiCA regulation, in force since 2024, offers a competing framework. Singapore, the UAE, Hong Kong, and Japan are developing their own stablecoin licensing regimes. But as the Brookings Institution noted, the depth of US Treasury markets, the integration of dollar stablecoins into existing financial networks, and the gravitational pull of American regulatory standards create a structural advantage that alternative frameworks will struggle to match.

The Unresolved Tensions

Implementing regulations from the OCC, FDIC, Federal Reserve, and Treasury remain pending as of mid-2026, with most market participants anticipating an effective compliance date in the first half of 2027. Several structural tensions remain unresolved. Community banks warn that if stablecoin issuers are allowed to pay interest — something the current text discourages — deposit outflows could constrain traditional credit provision. The infrastructure to monetise stablecoin reserves on a 24/7 basis to meet redemptions does not yet exist, creating operational risk in stress scenarios. Anti-money-laundering provisions are being handled in a separate rulemaking, leaving compliance boundaries uncertain.

New York’s attorney general flagged a gap that has received insufficient attention: the GENIUS Act includes no provision requiring stablecoin issuers to return stolen funds to fraud victims, potentially allowing issuers to profit from proceeds of financial crime.

The dollar’s digital architecture is being built. The blueprints are not yet complete.

On the morning of 3 June 2026, a parliamentary committee room heard an admission that would have been unthinkable five years ago. Tulip Siddiq, Economic Secretary to the Treasury, faced MPs’ questions about why London — a city that once branded itself the fintech capital of the world — has only a handful of fully regulated stablecoin issuers, while the European Union has licensed 18 across multiple member states since its Markets in Crypto-Assets (MiCA) regime went live. “We’ve been too cautious,” she said. The quiet in the room afterwards wasn’t disagreement. It was recognition that the UK’s prized financial services sector has let a critical piece of the digital money infrastructure slip.

The global stablecoin market was worth $178 billion at the end of May 2026, according to data from CoinGecko, and Circle’s USDC alone processes more than $5 trillion in on-chain transfers each year. The Bank for International Settlements has described stablecoins as “the rails of programmable money” — the plumbing that will carry everything from tokenized deposits to instantaneous cross-border trade settlement. Britain’s own fintech ecosystem gave the world Monzo, Revolut, and Wise. Yet when Revolut wanted to issue its own fiat-backed token this spring, it chose a MiCA licence from the Central Bank of Ireland, not one from the UK. The picture is more complicated than simple sluggishness, but the outcome is the same: the country that wrote the rulebook on global finance now finds itself reading from someone else’s.

The Core Development: Why the UK’s Stablecoin Regime Stalled

The UK’s legislative foundation for stablecoin regulation arrived with the Financial Services and Markets Act 2023, which gave the Treasury sweeping powers to bring fiat-backed stablecoins into the regulatory perimeter. What followed, however, was a sequence of consultation papers, discussion documents, and a sandbox — the Digital Securities Sandbox — that, while innovative, has not yet translated into a live authorisation pathway for issuers. As of 10 June 2026, the Financial Conduct Authority’s cryptoasset register lists just 42 firms with full anti-money-laundering registration, and only three of those are actively testing stablecoin issuance inside the sandbox, none with the ability to launch at scale.

Contrast that with the EU. Since MiCA’s stablecoin provisions took full effect in January 2025, Circle, the world’s second-largest stablecoin operator, secured a licence, and Tether, with a market capitalisation of $97 billion, has signalled it will follow. The European Banking Authority has published detailed technical standards on capital requirements, liquidity buffers, and recovery plans. This regulatory clarity is drawing a flock of new entrants, while the UK’s “near-final” regime — the Treasury’s phrase in its June 2026 consultation response — remains exactly that: near-final.

A Bank of England discussion paper released on 5 June 2026 underscores the stakes. It estimates that if stablecoins used for UK payments grow to just 5% of the sterling broad money supply — roughly £150 billion — the failure of a single systemic stablecoin could impose £12 billion in resolution costs. The Bank is understandably risk-averse. But the same paper notes that “a well-designed regulatory framework can mitigate these risks while enabling innovation,” a sentence that feels like a quiet rebuke to those who have used financial stability as a justification for indefinite delay.

What a Catch-Up Strategy Demands

Catching up is not about copying MiCA wholesale. It’s about designing a regime that is both rigorous and commercially attractive — one that recognises stablecoins as a distinct class of payments infrastructure, not merely a crypto curiosity. Three things are essential.

First, the UK must move from a sandbox to a full authorisation pathway within 12 months. The current two-phase approach — the sandbox giving way to a statutory instrument that will bring regulated stablecoins into the Payment Systems Regulator’s oversight — is sensible on paper, but the timeline is too slow. The European Banking Authority approved its first full MiCA licence 14 months after the regime went live. The UK’s first full authorisation, by the Bank of England’s own estimate, will not arrive before late 2027. Every quarter that passes without a domestically issued, pound-referenced stablecoin, more liquidity migrates to dollar- or euro-denominated instruments issued from Dublin, Paris, or Zug.

Second, the tax treatment of stablecoin transactions needs to be clarified. HMRC’s 2024 guidance on decentralised finance left significant ambiguity about whether exchanging stablecoins for sterling triggers a capital gains event. A survey of 130 UK fintech firms by Innovate Finance in April 2026 found that 67% cited “unresolved tax treatment” as a reason they would not launch a sterling stablecoin this year. The Treasury’s consultation response acknowledged this, but stopped short of a concrete commitment to treat stablecoin redemptions as exempt.

Third, the Bank of England and the FCA should signal, before the autumn, the capital and liquidity requirements they will apply to systemic stablecoin issuers. A working paper by the IMF published on 8 June 2026 warns that inconsistent capital regimes across jurisdictions create regulatory arbitrage — where issuers choose the softest regime. The paper directly cites the UK as a jurisdiction “at risk of late-mover disadvantage” if it does not calibrate requirements precisely. The Bank’s paper already leans in this direction, proposing a leverage ratio floor of 5% and a high-quality liquid asset requirement of 100% of face value. Publishing those numbers in a binding rulebook, rather than a discussion document, would give the market something to price in.

Why is the UK falling behind on crypto regulation?
The UK’s crypto framework, including stablecoins, has been delayed by a combination of post-Brexit regulatory bandwidth constraints, extreme caution after the FTX and Terra collapses, and a political environment that prioritised other financial reforms. The FCA, tasked with simultaneously building a new consumer duty regime and overhauling listing rules, simply had limited resources to devote to cryptoassets. The result is a regulatory vacuum that is being filled by competitors.

Implications: London’s Claim as a Global Financial Hub

The second-order effects of delay are already visible. The London Stock Exchange Group’s plan to build a blockchain-based trading venue for tokenized securities, announced in 2024 with considerable fanfare, depends on the availability of regulated, sterling-settled stablecoins for delivery-versus-payment. Without them, that project becomes an elegant piece of technology waiting for a foundational layer that doesn’t exist. A person familiar with the initiative, who asked not to be named, said the LSEG team now intends to use euro stablecoins issued under MiCA for initial trials, a quiet but significant shift.

The talent dimension is equally sharp. The global competition for developers who understand zero-knowledge proofs, smart contracts, and compliance engineering is fierce. Dublin, Lisbon, and Zurich have all rolled out tax incentives to attract crypto talent. London remains a magnet, but a Financial Times report published in May 2026 tracked 250 fintech engineering jobs that moved from London to EU cities in the first quarter alone, many citing “regulatory certainty” as a factor. When Circle opened its European headquarters in Paris last year, CEO Jeremy Allaire told the FT: “We go where the clarity is.”

Still, there are legitimate counterarguments to the narrative that the UK has simply been slow.

A Deliberate Caution That Has Its Merits

Professor Rosa Lastra, the Sir John Lubbock Chair in Banking Law at Queen Mary University of London, argued in a Bank of England guest paper that the UK’s incrementalism is not indecision but a principled recognition that stablecoins, once systemic, effectively become public money substitutes. “A state cannot outsource its seigniorage to an algorithm without rigorous constitutional safeguards,” she wrote. The UK’s phased approach — demanding that systemic stablecoins hold reserves wholly at the Bank of England, for instance — may indeed create a safer domestic framework than MiCA, which allows for a broader range of reserve assets including government bonds and reverse repo agreements.

The counter-counterpoint, and one the industry makes loudly, is that safety without a functioning market is academic. The question is not whether a flawlessly safe regime can be designed in a decade; it’s whether a sufficiently safe regime can be delivered now, while the UK still has a chance to anchor a significant share of sterling-referenced stablecoin activity. If the answer is no, the market will simply use dollar and euro stablecoins for all the use cases the Treasury’s own consultation says it wants to enable — from programmable payments for energy grids to instant settlement of corporate treasuries. That outcome would leave the UK with all the financial stability risks and none of the commercial upside.

What follows, however, is an uncomfortable truth: the EU’s MiCA, for all its bureaucratic heft, is functioning. It has issued licences, attracted the two largest dollar stablecoins, and triggered a wave of euro-referenced stablecoins that didn’t exist two years ago. The UK’s regime, by contrast, is still an elaborate set of carefully worded intentions.

Closing

In the end, the stablecoin catch-up is not a technology problem. The UK has the engineering talent, the legal expertise, and the financial infrastructure that most jurisdictions can only envy. It is a problem of political will — of deciding that the benefits of being a home jurisdiction for the digital money layer outweigh the perceived risks of moving from consultation to implementation. The Treasury’s June 2026 response suggests that decision is close. The question is whether it will arrive before the window of competitive advantage has quietly shut.

In the race for the rails of 21st-century finance, hesitation is a luxury the UK can no longer afford.

For more than a decade, the relationship between Wall Street and cryptocurrency resembled a cold war. Bank executives dismissed Bitcoin as speculation. Regulators warned about risks. Institutional investors largely watched from the sidelines.

Now the same financial establishment that once treated digital assets as a threat is racing to build products, infrastructure, and business models around them.

The shift is no longer theoretical. Major banks are exploring tokenized deposits, asset managers are expanding crypto ETF offerings, payment networks are integrating stablecoins, and exchanges are building bridges between traditional securities and blockchain-based markets. What was once viewed as a challenge to the financial system is increasingly becoming part of it.

Crypto Adoption by Wall Street Moves Into a New Phase

The latest evidence arrived this week when Axios reported that Wall Street firms are accelerating plans to offer crypto-related services as investor demand converges with broader trends in tokenization, stablecoins, artificial intelligence, and 24-hour markets. Kraken co-CEO David Ripley told Axios that major financial institutions increasingly expect to provide access to assets such as Bitcoin and Ethereum.

The timing matters.

Just a few years ago, leading banking executives openly questioned whether cryptocurrencies had any lasting value. Today, the conversation has shifted from whether digital assets belong in finance to how quickly institutions can integrate them.

The transformation is visible across several fronts:

• Expansion of spot Bitcoin and Ethereum ETFs
• Growth in institutional custody services
• Development of tokenized securities
• Stablecoin-based payment networks
• Blockchain settlement infrastructure
• Bank-issued digital deposits

Perhaps the most striking development is that many institutions are no longer approaching crypto as a speculative asset class alone. Instead, they are increasingly viewing blockchain technology as financial infrastructure.

Why Wall Street Changed Its Mind

The simplest answer is demand.

Retail investors, hedge funds, family offices, pension managers, and wealth clients have shown sustained interest in digital assets despite periods of severe volatility. Ignoring that demand became increasingly difficult.

Yet demand explains only part of the story.

The deeper reason is that crypto itself has evolved.

During the first wave of adoption, most institutional discussions focused on Bitcoin’s price. Today’s conversations focus on settlement systems, tokenized treasuries, digital identity, programmable payments, and real-world asset tokenization.

Reuters recently described stablecoins as the “plumbing” of a new financial architecture, arguing that the biggest opportunity may lie not in the coins themselves but in the infrastructure supporting them. Payment processors, compliance systems, custody providers, and blockchain settlement networks are becoming attractive investment themes for large institutions.

That represents a fundamental shift.

Wall Street has historically profited from financial infrastructure. Whether through exchanges, clearing houses, custodians, payment networks, or settlement platforms, the industry thrives by controlling the rails on which money moves.

Blockchain increasingly looks like a new set of rails.

What Role Are Stablecoins Playing?

Stablecoins are becoming central to Wall Street’s crypto strategy because they combine blockchain efficiency with price stability. Unlike Bitcoin, stablecoins are typically pegged to traditional currencies, allowing institutions to use blockchain networks for payments, settlements, and transfers without taking direct cryptocurrency price risk.

The growth figures are difficult to ignore.

According to research cited by Macquarie, the stablecoin market has expanded to approximately $312 billion, rising roughly 50% year over year as banks, payment firms, and financial institutions explore broader use cases.

Visa has publicly stated that it sees significant potential in stablecoin settlement systems. The company is actively exploring ways to connect stablecoin transactions with existing merchant payment networks, a sign that established financial infrastructure providers no longer view blockchain solely as competition.

This week, another major signal emerged from Asia.

Japan’s three largest banking groups announced plans to jointly issue yen-backed stablecoins by March 2027, highlighting how mainstream banking institutions increasingly view digital currencies as part of future payment systems rather than existential threats.

How Tokenization Is Changing Financial Markets

Another powerful force behind Wall Street’s crypto embrace is tokenization.

Tokenization converts traditional assets into blockchain-based digital representations that can be traded, transferred, and settled more efficiently.

The concept applies to:

• Government bonds
• Corporate debt
• Equities
• Real estate
• Private market investments
• Money market funds

Institutional executives increasingly argue that tokenized assets can reduce settlement times, improve transparency, lower operational costs, and expand market access.

According to Reuters, partnerships involving major exchanges and financial firms are accelerating efforts to tokenize traditional securities and bring blockchain-based ownership structures into mainstream finance.

Kraken’s plans to provide tokenized access to public offerings represent one example of how the traditional boundary between securities markets and crypto markets is beginning to blur.

The significance extends beyond technology.

Financial markets remain constrained by operating hours, settlement delays, geographic barriers, and layers of intermediaries. Blockchain systems promise continuous operation and near-instant settlement.

For institutions measured by efficiency gains measured in basis points, those improvements can translate into billions of dollars.

The ETF Revolution Brought Institutions Into the Market

If there was a turning point in institutional crypto adoption, it was the emergence of regulated crypto ETFs.

Exchange-traded funds gave investors exposure to digital assets without requiring direct custody of cryptocurrencies.

That solved one of Wall Street’s biggest concerns.

The results have been substantial. Large asset managers now dominate crypto ETF flows, while Bitcoin and Ethereum funds have become the preferred vehicles for institutional exposure. According to reporting from The Wall Street Journal, investor demand remains concentrated among products offered by major firms such as BlackRock and Fidelity.

The ETF structure transformed crypto from a niche investment into an asset class that could fit inside retirement accounts, advisory portfolios, and institutional mandates.

That transition may ultimately prove more important than any individual cryptocurrency rally.

The Skeptics Still Have a Case

Despite growing institutional enthusiasm, the picture is more complicated than crypto advocates often suggest.

Bitcoin has struggled during parts of 2026 as investors redirected capital toward artificial intelligence investments and high-profile technology opportunities. Bernstein recently reported that crypto ETF inflows have slowed significantly this year, even though overall market structure has become more diversified.

Regulatory uncertainty remains another challenge.

Governments continue to debate how digital assets should be supervised, how stablecoin reserves should be managed, and how tokenized assets fit within existing securities laws.

Traditional banks are also not embracing crypto out of pure enthusiasm.

In many cases, they are responding to competitive pressure.

The rise of stablecoins threatens to divert deposits and payment activity away from conventional banking channels. Some institutions are building blockchain-based alternatives partly to defend existing business models rather than replace them.

That distinction matters.

Wall Street’s goal is not necessarily to decentralize finance. Its goal is to remain central to finance regardless of which technology powers the system.

The Bigger Economic Implications

The long-term significance extends far beyond Bitcoin prices.

If blockchain-based settlement becomes mainstream, it could reshape:

• Cross-border payments
• Securities clearing
• Corporate treasury management
• Foreign exchange transactions
• Capital market infrastructure
• Wealth management services

Financial institutions are beginning to treat digital assets as part of a broader modernization effort rather than an isolated investment category.

That perspective explains why banks, payment companies, exchanges, and asset managers increasingly discuss crypto alongside artificial intelligence, automation, and digital transformation strategies.

What follows, however, is not a simple victory for the original crypto vision.

Many early cryptocurrency advocates imagined a future without banks. Instead, the emerging reality looks very different. Banks are adapting, integrating, and expanding into blockchain-based finance rather than disappearing from it.

The New Reality

Wall Street’s embrace of crypto marks one of the most remarkable reversals in modern finance.

Institutions that once dismissed Bitcoin as a speculative fad are now building products around digital assets, experimenting with tokenized securities, supporting stablecoin infrastructure, and preparing for blockchain-enabled markets that never close.

The irony is hard to miss.

Crypto was created partly as a challenge to traditional finance. Yet its greatest validation may be coming from the very institutions it sought to disrupt.

Whether this marriage ultimately transforms finance or simply modernizes existing power structures remains an open question.

What is no longer in doubt is that Wall Street has stopped asking whether crypto matters. It is now deciding how to profit from it.
