Britain's new cryptocurrency rules will benefit big companies first, or everyone in the future

New UK crypto regulatory rules: Give priority to serving large companies or protect ordinary consumers?

For years, the UK's cryptocurrency industry has complained that regulators are slow to act, while competitors in Europe, the United States and the Middle East are moving forward quickly. On June 30, 2026, the UK's Financial Conduct Authority (FCA) finally released the country's most comprehensive cryptocurrency rulebook to date. The plan is based on the law passed by Parliament in February 2026, formally bringing crypto assets into the FCA's regulatory scope, covering almost all major parts of the digital asset industry: stablecoins, cryptocurrency trading platforms, custody service providers, market abuse and prudent capital requirements. In addition, the FCA and the Bank of England issued a joint statement outlining how they can jointly supervise stablecoin issuers in the future, as as discussed in this article, the two regulators ultimately cover different parts of the same market.

Companies can apply for authorization from September 30, 2026 to February 28, 2027, and the comprehensive regulatory system will officially take effect on October 25, 2027. As regulators softened several proposals after months of consultation, the announcement was welcomed by most of the cryptocurrency industry. The most significant change is a reduction in capital buffer requirements for the largest stablecoin issuers, a move that could free up hundreds of millions of pounds for investment and expansion. Proponents believe the FCA strikes a cautious balance between protecting consumers and encouraging innovation, but critics hold the opposite view. They believe that regulators have quietly passed on more risk to consumers while making life easier for large cryptocurrency companies, raising a bigger question: Who was the rule book designed for? Is it designed to help ordinary Britons use digital assets safely, or is it mainly to make the UK more attractive to billion-pound cryptocurrency companies? The answer is much more complicated than either party is willing to admit.

Explanation of Terms

Before delving into the rules, several key terms are explained here in plain language:

• K-SII Enterprise: refers to large stablecoin issuers classified as "systemically important stablecoin issuers."
• Capital buffer: Additional capital held by financial institutions to absorb shocks when losses occur, similar to a shock absorber for a car.
• MARC：The Market Abuse Regime for Cryptoassets is designed to combat insider trading and market manipulation.
• Macroprudential Barrier: Regulatory measures designed to prevent individual institutions from becoming too big and damaging the entire financial system.

The rule that changes everything

The biggest headlines in the FCA's final plan are not about Bitcoin, but about capital. When regulators first proposed their framework, they wanted the largest stablecoin issuers (i.e., companies classified as K-SII) to hold capital equivalent to 2% of the value of assets of their managed clients. After consultation, this requirement was halved and was finally set at 1%. Although this may seem like a minor adjustment, from an economic perspective, it is by no means the case. The main reason is that if you have a stablecoin issuer that manages £ 10 billion of client funds, under the original proposal, it needs to lock in £ 200 million of its own capital. Under the final rules, it only needed £ 100 million, freeing up another £ 100 million.

The FCA argues that this makes the framework more proportional and avoids discouraging innovation, but industry feedback suggests that the initial requirements will impose costs that are difficult to justify, especially for companies trying to expand in a globally competitive market. From a business perspective, this change is completely logical, mainly because capital costs are high and every money locked up cannot be used to hire engineers, expand into new markets, or develop new products. As a result, lowering capital requirements increases a company's return on equity (ROE), one of the most important metrics investors use when deciding on capital allocation. That's why banks, insurance companies and payment companies often lobby against excessive capital requirements: The more money regulators force a company to idle, the lower its profitability.

The cost of reducing capital

Capital buffers exist for a reason: they help absorb losses when things go wrong. Capital can be compared to the shock absorber of a car. Removing half of the shock absorbers will make the vehicle lighter and cheaper to run, but the ride will be more bumpy and riskier when road conditions are bad. The same goes for stablecoin issuers. If operational failures, cyber attacks, or legal disputes result in unexpected losses, the company's own capital should be used to absorb those losses so customers don't feel the impact. A smaller buffer means less room for fault tolerance, which is why the FCA's decision divides economists. One side believes that well-designed reserve requirements already protect customers and therefore do not require large capital buffers; the other side believes that recent financial history, from the 2008 banking crisis to the failure of Silicon Valley banks, suggests that financial institutions almost always look safe until they collapse suddenly.

Why the FCA made a compromise

The FCA did not make this change in isolation. During consultations, cryptocurrency companies argued that the rules proposed by the UK are much stricter than those being developed in other jurisdictions. This is important because the digital asset business has exceptionally high liquidity. Unlike traditional banks, cryptocurrency exchanges can transfer most of their legal structure, technology and management to another jurisdiction relatively quickly. This creates real regulatory competition, with countries competing not only in terms of taxation, but also in terms of the attractiveness of their regulatory environments. If one jurisdiction becomes too restrictive, companies often choose to establish their presence elsewhere. The UK has already seen part of its fintech ecosystem expand into Dubai, where the Virtual Assets Supervisory Authority (VARA) positions itself as a cryptocurrency-friendly regulator; meanwhile, the European Union's Crypto-Asset Markets (MiCA) framework provides companies with access to a single market covering 27 countries. Across the Atlantic, the United States has also taken a step closer to a comprehensive stablecoin framework, putting further pressure on the UK to remain competitive. In other words, lowering capital requirements is not just about making cryptocurrency companies happier, but about preventing the UK from excluding itself from this fast-growing global industry due to excessive costs.

£ 40 billion cap that few consumers notice

Early proposals include setting limits on the number of stablecoins that individuals and businesses can hold: £ 20,000 for retail users and £ 10m for businesses. These proposals were subsequently withdrawn. But it was not the FCA that revoked them, but the Bank of England. The Bank of England oversees different levels of the market: the largest, systemically important stablecoins, which are separate from the broader group of K-SII issuers covered by the FCA. The two regulators detailed how this division of labor works in a joint statement issued along with the FCA's June rules.

The Bank of England did not set a cap on individual positions, but introduced an issuance threshold of £ 40 billion per systemic stablecoin issuer. This is a cap on the size of a company, not a limit on the amount any individual or business can hold. The Bank of England no longer tells consumers how many stablecoins they can own, but focuses on the size of the company issuing stablecoins. This shows a broader concern about the issue of "deposit migration" within central banks. If millions of people move money from bank deposits into privately issued stablecoins, commercial banks will lose a key source of funding. As we all know, banks don't just store deposits; they use deposits to fund mortgages, business loans and consumer credit. Lower deposits mean higher financing costs, which could translate into increased borrowing costs across the economy. From the Bank of England's perspective, the £ 40 billion threshold serves as a macroprudential fence designed to prevent any single private stablecoin from becoming so large that it materially disrupts the UK's banking system before regulators have the opportunity to reassess risks. It's important to note: This cap is designed to protect the stability of the financial system, not to restrict individuals 'financial freedom.

Assets behind each stablecoin

The most important question most people never ask is also the simplest question: What is my stablecoin actually backed by? The answer determines whether a stablecoin deserves the word "stable". Although the Bank of England and the FCA have made it clear that regulated sterling stablecoins cannot just promise stability, they must prove this every day. Under the new framework, issuers are expected to hold high-quality, highly liquid reserve assets that can be quickly converted into cash even during periods of market stress. In practice, this means that reserves are expected to consist mainly of cash held with regulated banks or the Bank of England and short-term UK government securities (gilts). The rules are deliberately strict because the goal is not to maximize issuers 'returns, but to ensure that customers can redeem their stablecoins at face value at any time. However, under this framework, something is missing.

There is little room for riskier corporate bonds, stocks, real estate investments, or speculative crypto assets that could yield higher returns, but also introduces the possibility that reserve assets will just depreciate when customers want their money back. The collapse of TerraUSD in 2022 and the temporary decoupling of the USDC during the 2023 Silicon Valley banking crisis reinforced this lesson. Both incidents suggest that confidence quickly dissipates when users begin to question the quality or accessibility of reserve assets.

What protection do consumers really receive?

From an economic perspective, the UK's approach reflects a simple trade-off: the safer the reserve portfolio, the lower the return the issuer will get from it. A lower return is to lower the price of the destabilizing run. The FCA actually chose financial stability over higher corporate returns. The FCA has repeatedly described the new system as being built around consumer protection, but if you are an ordinary person buying £ 500 stablecoin, what does that mean? First, regulated issuers must maintain full reserve reserves that match the value of outstanding stablecoins. Secondly, customers have the right to redeem stablecoins at their face value under the conditions set out in the regulatory framework; third, cryptocurrency custodians must separate customer assets from their own funds to reduce the risk of customer assets getting entangled in the event of a company bankruptcy. Trading platforms must also implement stronger governance, operational resilience measures, and design systems to detect insider trading and market manipulation in accordance with the new Crypto Asset Market Abuse Regulation (MARC).

Who really benefits?

The biggest direct beneficiaries appear to be large, well-capitalized cryptocurrency companies. Lower capital requirements reduce compliance costs, and removing personal and business position caps makes it easier to attract wealthy and institutional clients. Providing regulatory certainty also makes it easier to raise venture capital because investors finally know the rules of the game. For consumers, the benefits are less immediate but still real, and greater regulatory clarity should encourage more reputable companies to enter the UK market, leading to increased competition and potentially lower fees. Consumers may also get products that were previously not launched because regulatory uncertainty made investments too risky, but the difficult question is whether future benefits justify reducing the safety buffer today. Proponents argue that the 1% capital requirement is still proportional because reserve support provides the main layer of protection, but critics counter that capital exists precisely because unexpected losses occur; history provides examples in support of both views.

Political factors for lifting the £ 20,000 cap

During the consultation, no proposal attracted as much attention as the original £ 20,000 cap on personal stablecoin holdings, mainly because removing it sounded like a straightforward victory for financial freedom: people, not governments, should decide how much digital currency they hold. But there is another way to interpret it. According to FCA's consumer research, relatively few UK cryptocurrency holders have portfolios close to that size, with most retail investors holding well below £ 5000. This means that lifting the cap will have little impact on ordinary working families. It mainly benefits wealthy investors, professional traders and companies that manage large balances of digital assets, which has political weight. Britain has experienced years of debate over the gap between rich and poor, stagnant wages and a cost-of-living crisis. Polls consistently show strong public support for measures that require high-income earners and large businesses to contribute more through taxation and regulation. Against this backdrop, critics believe that one of the FCA's most important concessions mainly benefits those who already have large amounts of financial assets. However, supporters have a different view, arguing that regulation should not discriminate against consumers based on portfolio size and that wealthy individuals should not face arbitrary restrictions simply because they choose digital assets over traditional investments. Both arguments make sense, but it is difficult to claim that lifting the cap will substantially improve the financial inclusion of the UK's working class.

Conclusion: A rule book for growth, not revolution

The FCA's final cryptocurrency rule book is neither an industry wish list nor a nightmare for its critics, but there are compromises here. Regulators have softened some important requirements, especially on capital, while retaining strict standards of reserves, custody and market integrity. From an economic perspective, the framework tends towards growth rather than maximum resilience because it lowers barriers to entry for companies without abandoning safeguards that distinguish regulated finance from the previously large-unregulated crypto markets. But does it mainly help the working class? Well, not directly; most ordinary Britons will not notice the immediate difference beyond the possibility of exposure to a wider range of regulated cryptocurrency products over time. Eliminating position caps, reducing capital requirements and providing more flexibility will, in the first place, benefit issuers and larger market participants. The FCA seems to believe that these benefits will ultimately be trickled down through greater competition, innovation and cost reduction, but whether this is true is still uncertain, but what is certain is that the UK has made the choice and is not trying to suppress cryptocurrency, but trying to shape it.

The real test begins now: between the opening of the authorization window in September 2026 and the full implementation of the system in October 2027, regulators, banks, cryptocurrency companies and consumers will all discover whether the framework meets the balance the UK has been looking for. There's another unanswered question: If most Britons still view cryptocurrencies primarily as an investment vehicle rather than a payment instrument, is the FCA regulating today's markets or preparing for the markets it wants to exist tomorrow?

Frequently Asked Questions (FAQs)

What changes has the FCA made in its final cryptocurrency rulebook?

The FCA cut the capital requirements for stablecoin issuers (known as the K-SII factor) from 2% to 1% of the value of the stablecoin in circulation and subject to redemption. It also set a permanent minimum capital floor for issuers at £ 350,000, introduced a new Crypto Asset Market Abuse Regulation (MARC), and finalized rules covering trading platforms, custody providers and prudent capital across the industry.

When can cryptocurrency companies apply for FCA authorization?

The authorization window will open on September 30, 2026 and close on February 28, 2027. A comprehensive regulatory regime (covering trading platforms, intermediaries, custodians, stablecoin issuers and pledge providers) will take effect on October 25, 2027.

Has the FCA lifted the £ 20,000 cap on stablecoin positions?

No, the FCA has never had rules to cancel. The £ 20,000 individual and £ 10m corporate caps were originally proposed by the Bank of England, rather than the FCA, as part of its separate oversight of the largest, systemically important stablecoins. The Bank of England subsequently abolished these caps completely and replaced them with a £ 40 billion issuance threshold for each systemic stablecoin issuer, a limit on how much stablecoin companies can grow, rather than how much any individual or business can hold.

Is the FCA responsible for overseeing UK stablecoins?

is responsible for both, but for different parts of the market. The FCA regulates a broader group of stablecoin issuers and crypto asset companies under its new rule book. The Bank of England separately supervises systemically important stablecoins, those large enough to threaten financial stability. The two regulators issued a joint statement outlining ways in which they coordinate oversight.

Why did the FCA reduce capital requirements for stablecoin issuers?

The FCA said industry feedback suggested that its original 2% proposal was set too high and could hinder the company from starting or expanding in the UK. David Geale, executive director of the FCA, admitted this directly, saying the regulator was "starting from a little high." Lower capital requirements free up money issuers would otherwise have to idle, although critics believe the same buffer exists to absorb losses if problems arise.

Under the new UK rules, what assets can regulated stablecoins be backed by?

Reserves must consist of cash held with regulated banks or the Bank of England and short-term UK government securities (gilts), a requirement set for standard issuers in the FCA's stablecoin issuance rules (PS26/10). Risky assets such as corporate bonds, stocks, real estate or other crypto assets are not allowed. Stabiloins large enough to be designated as systemic by the Treasury belong to a separate, co-managed framework with the Bank of England, which applies its own code of conduct on top of the FCA's underlying rules. In any case, the goal is the same: reserves are safe and liquid enough so that stablecoins can still be redeemed at face value under market pressure.

Will the new FCA rule book mainly benefit large cryptocurrency companies or ordinary consumers?

Large, well-capitalized companies see the most immediate benefits by reducing compliance costs and removing position caps that make it more difficult to attract institutional clients. Consumer interests are less direct: Greater regulatory clarity may encourage more reputable companies to enter the UK market, which may increase competition and reduce fees over time, although most ordinary users will not notice the immediate difference.
