Introduction
The meteoric rise of cryptoassets has presented a profound challenge to traditional legal and regulatory paradigms. Hailed by some as the foundation of a new, decentralised financial system, the cryptoasset market has also been described as a ‘Wild West’, replete with fraud, manipulation, and extreme volatility, exposing consumers to significant risks of financial loss (FCA, 2021). In response, jurisdictions worldwide are moving to impose order on this nascent industry. The UK, aspiring to be a “global hub for cryptoasset technology” (HM Treasury, 2023a), has taken a decisive step with the Financial Services and Markets Act 2023 (FSMA 2023), which brings cryptoassets definitively within the regulatory perimeter. A central pillar of this new framework is the extension of the market abuse regime to cover cryptoasset trading. This essay will critically evaluate whether this new regime will, in fact, make digital finance safer.
This essay will argue that while the UK’s extension of the market abuse regime to cryptoassets is a necessary and significant advancement that will incrementally improve safety, its effectiveness will be substantially constrained by the unique and challenging characteristics of the cryptoasset ecosystem. The analysis will demonstrate that fundamental obstacles, including the global, borderless nature of crypto markets, the challenge posed by pseudonymity to enforcement, and the conceptual difficulty of applying traditional market abuse rules to novel digital assets, will temper the regime’s impact. Consequently, while the framework will foster greater market integrity and investor protection within its jurisdictional reach, it will not, in isolation, transform digital finance into a ‘safe’ harbour. Achieving a meaningful state of safety will necessitate a more holistic approach, combining the new rules with robust international cooperation, advanced supervisory technology, and a realistic appraisal of the inherent risks that regulation alone cannot eliminate.
The Unregulated ‘Wild West’: Market Abuse in Crypto ecosystems
To assess whether the new regime will make digital finance safer, it is essential to first understand the unsafety it seeks to remedy. The cryptoasset market has, to date, operated largely outside the purview of conduct-based financial regulation, creating fertile ground for abusive practices analogous to those seen in traditional securities markets but amplified by technology and a lack of oversight. Prevalent manipulative schemes include ‘pump and dump’ operations, where influencers and coordinated groups artificially inflate the price of a token before selling, leaving retail investors with near-worthless assets (Xu and Livshits, 2019). Similarly, ‘wash trading’—where a trader simultaneously buys and sells the same asset to create a false impression of market activity—is reportedly rampant on some unregulated exchanges, distorting price discovery (Cong et al., 2022).
Furthermore, insider dealing has found a new guise in the crypto world. For instance, employees of crypto exchanges with knowledge of an impending token listing—an event that typically boosts a token’s price—can use that non-public information to profit, a practice that has led to criminal prosecution in the United States (United States v Wahi, 2023). These activities undermine the core tenets of a fair market: transparency, price integrity, and a level playing field. They erode trust and deter both institutional and retail participation, legitimising calls for regulatory intervention. While existing general laws such as the Fraud Act 2006 theoretically apply, their application is fraught with difficulty, requiring high standards of proof for dishonesty and intent that are hard to meet in the complex, pseudonymous context of crypto trading (Fletcher, 2022). The demonstrated inadequacy of the existing legal toolkit provides the core justification for a bespoke market abuse regime.
Extending the Perimeter: The UK’s New Cryptoasset Market Abuse Framework
The UK’s strategy, articulated through a series of consultations and culminating in FSMA 2023, is not to reinvent the wheel but to extend the existing, well-understood framework for traditional finance to this new asset class. The government’s approach is founded on the principle of ‘same risk, same regulatory outcome’ (HM Treasury, 2023b). The cornerstone of this is Part 2 of FSMA 2023, which amends the Financial Services and Markets Act 2000 (FSMA 2000) and the Regulated Activities Order 2001 to define cryptoassets as a specific type of regulated investment.
The most significant consequence of this legislative change will be the application of the UK’s Market Abuse Regulation (UK MAR) to cryptoassets admitted to trading on a UK-based crypto trading venue. UK MAR, which originated from EU law and was onshored post-Brexit, prohibits three core abusive behaviours:
- Insider dealing: Unlawfully using, or attempting to use, inside information to trade in financial instruments.
- Unlawful disclosure of inside information: Improperly disclosing inside information to another person.
- Market manipulation: Engaging in, or attempting to engage in, activities that give or are likely to give false or misleading signals as to the supply, demand, or price of an instrument, or which secure the price at an artificial level (UK MAR, Articles 12, 14, 15).
Bringing cryptoassets under this umbrella empowers the Financial Conduct Authority (FCA) to police crypto markets with a formidable toolkit. The FCA will be able to surveil trading activity, demand information from firms, and impose significant sanctions for breaches, including substantial financial penalties, public censures, and injunctions. In serious cases, evidence can be passed to law enforcement for criminal prosecution under either the civil regime’s criminal counterparts or other statutes. This structured approach, replacing legal ambiguity with a defined rulebook and a powerful regulator, represents a clear and intentional effort to make the UK’s domestic crypto market demonstrably safer for participants.
Building the Foundations of Trust: How the Regime Aims to Enhance Safety
The introduction of a dedicated market abuse regime for cryptoassets has the potential to enhance safety in several critical ways. Firstly, and most directly, it serves as a powerful deterrent. The existence of clear prohibitions and the credible threat of substantial FCA sanctions should discourage overtly manipulative behaviour on regulated UK platforms. This will foster a higher standard of market conduct, directly protecting investors from the most egregious forms of abuse like wash trading and orchestrated pump-and-dump schemes. By establishing a minimum standard of behaviour, the regime aims to cleanse the market of its most toxic elements, thereby increasing investor protection.
Secondly, the regime is crucial for building market integrity and, by extension, consumer and institutional confidence. A key barrier to the maturation of the crypto market has been the reluctance of institutional investors—such as pension funds and asset managers—to engage with an asset class plagued by reputational risk and regulatory uncertainty (Chainalysis, 2023). A robust market abuse framework is a precondition for such investors. By aligning the rules for crypto with those for equities and bonds, the UK signals that it is creating a serious, investment-grade market. This can create a virtuous circle: higher integrity attracts more sophisticated, long-term capital, which in turn promotes greater liquidity and stability, making the market inherently safer and more reliable. This aligns directly with the government’s ambition to make the UK a competitive and attractive jurisdiction for digital finance.
Thirdly, the regime provides much-needed legal certainty for market participants. For crypto exchanges, token issuers, and other intermediaries, the previous state of ambiguity was operationally challenging. A formal regulatory framework, while imposing compliance costs, clarifies their obligations regarding market surveillance, the handling of inside information, and reporting suspicious activity. This clarity reduces legal risk for businesses and helps to professionalise the industry from within. This is comparable to the EU’s approach with the Markets in Crypto-Assets (MiCA) Regulation, which also includes a comprehensive suite of rules to combat market abuse. This international convergence on the necessity of such rules demonstrates a broad consensus that they are a foundational component of a ‘safe’ digital finance ecosystem.
A Regime Under Strain: The Enduring Challenges to Making Crypto Safe
Despite these significant potential benefits, the assertion that the new regime will make digital finance ‘safe’ must be heavily qualified. A critical analysis reveals profound structural and technological challenges that will severely test the limits of the UK MAR framework and the FCA’s ability to enforce it.
The Cross-Border Conundrum
The most formidable challenge is the inherently global and decentralised nature of cryptoassets. UK MAR will apply to cryptoassets admitted to trading on a UK-regulated trading venue, or where the offending conduct occurs within the UK. However, a UK-based investor can easily access and trade on an exchange based in a jurisdiction with lax or non-existent regulation. A manipulative scheme can be orchestrated from abroad, targeting a token that is traded globally, with effects felt by UK investors but with the perpetrators remaining beyond the FCA’s jurisdictional grasp. While the FCA has powers to act against unauthorised firms targeting UK consumers, enforcing these powers against elusive, offshore entities with no physical presence in the UK is exceptionally difficult (Chiu, 2022). The regime may therefore simply create a two-tier system: a cleaner, regulated ‘on-shore’ market for UK-based exchanges, and a persistently risky ‘off-shore’ market where UK consumers remain vulnerable. True safety is compromised as long as this global regulatory arbitrage remains possible.
The Pseudonymity Hurdle
Traditional market abuse enforcement relies heavily on the ability to identify who is trading. The regulatory architecture of traditional finance is built around accounts tied to verified legal identities. In contrast, the cryptoasset world operates on the basis of pseudonymity; transactions are linked to alphanumeric wallet addresses, not names. While the blockchain’s transparent ledger allows for the tracing of funds, attributing those addresses to specific individuals or entities responsible for market abuse is a significant technical and evidential hurdle (De Filippi and Wright, 2018). How can the FCA prove, to the required standard, that a particular wallet address used in a suspicious trading pattern belongs to a corporate insider? While blockchain analytics firms are developing sophisticated tools to de-anonymise transactions, this creates a costly and complex technological arms race between perpetrators and regulators. This evidentiary gap poses a fundamental threat to the effective application of rules against insider dealing and market manipulation.
Applying Analogue Concepts to a Digital World
A further challenge lies in the conceptual mismatch when applying rules designed for traditional securities to the novel world of cryptoassets. The definition of ‘inside information’ under UK MAR, for example, is “information of a precise nature, which has not been made public, relating, directly or indirectly, to one or more issuers or to one or more financial instruments, and which, if it were made public, would be likely to have a significant effect on the prices of those financial instruments” (UK MAR, Article 7). Applying this to a decentralised cryptoasset like Bitcoin, which has no ‘issuer’, is problematic. For other tokens, what constitutes material, non-public information? Is a lead developer’s knowledge of a critical bug in the code ‘inside information’? Is an influencer’s plan, before they announce it, to endorse a token ‘inside information’? The lines between legitimate information discovery and unlawful insider knowledge are far blurrier than in the corporate world of quarterly earnings reports and merger announcements (Markham and Guttman, 2021). Similarly, distinguishing between illicit ‘market manipulation’ and the legitimate, if frenetic, community-driven hype that characterises ‘meme coin’ phenomena will be a major interpretive challenge for the FCA and, eventually, the courts. This uncertainty risks either chilling legitimate activity or proving the rules to be unenforceable in practice.
The Challenge of Enforcement and Resources
Finally, there is the practical question of regulatory capacity. The crypto market is a 24/7 global marketplace generating an immense volume of data from thousands of different assets across numerous platforms. Effectively policing this environment requires not only immense financial resources but also highly specialised technical expertise in areas like blockchain forensics and data science. There are legitimate concerns about whether the FCA is sufficiently equipped to meet this challenge without a substantial increase in its budget and technological capabilities (House of Commons Treasury Committee, 2023). Without the capacity for proactive surveillance and swift enforcement, the new regime risks becoming a ‘paper tiger’—a set of rules that look good on paper but have little practical impact on deterring illicit behaviour.
Beyond Market Abuse: A Multi-faceted Approach to Digital Finance Safety
The analysis thus far reveals that while the market abuse regime is a crucial component of the regulatory architecture, it cannot single-handedly make digital finance ‘safe’. The concept of safety is multifaceted, and addressing market conduct alone leaves investors exposed to a host of other significant risks. A truly effective framework requires a holistic approach.
First, the cross-border challenge necessitates deep and effective international cooperation. The UK’s regime will be most effective if it is part of a global network of similar regulations, supported by information-sharing agreements and cooperative enforcement actions. Global standard-setting bodies like the Financial Stability Board (FSB) and the International Organization of Securities Commissions (IOSCO) are developing frameworks for crypto regulation (IOSCO, 2023). The UK’s success will be contingent on its ability to align with and contribute to these international efforts, closing the gaps that allow for regulatory arbitrage.
Second, regulation must adapt technologically. For regulators to keep pace with a technologically driven industry, they must themselves embrace technology. This means investing in ‘Supervisory Technology’ (SupTech) and ‘Regulatory Technology’ (RegTech) that can automate the surveillance of blockchain data, identify suspicious patterns in real-time, and streamline reporting. The effectiveness of the market abuse regime will depend as much on the FCA’s data scientists as on its lawyers and investigators.
Finally, it is vital to recognise the limits of what this type of regulation can achieve. The market abuse regime is designed to combat illicit conduct, not poor investment decisions or inherent market volatility. Cryptoassets remain, for the most part, highly speculative and risky. No amount of market conduct regulation can protect an investor from the price of a cryptoasset falling to zero due to a shift in market sentiment or a failure of the underlying project. Therefore, ‘safety’ must also involve robust consumer protection rules, clear and stark risk warnings—which the FCA has already strengthened for crypto promotions (FCA, 2023)—and a sustained campaign of consumer education to ensure that investors understand the fundamental risks they are taking, even within a regulated market.
Conclusion
The extension of the UK’s market abuse regime to cryptoassets is an unequivocal and positive step towards making digital finance safer. By outlawing manipulative practices and empowering the FCA to police the market, the framework promises to enhance investor protection, build market integrity, and provide much-needed legal certainty. It lays the foundational layer of trust necessary for the UK’s crypto sector to mature and for its ambitions as a global crypto hub to be credible. In this regard, the regime will undoubtedly make the UK’s domestic digital finance ecosystem safer than its current, largely unregulated state.
However, this essay has argued that the promise of ‘safety’ must be met with a strong dose of realism. The regime’s effectiveness will be significantly mitigated by the inherent nature of the technology it seeks to regulate. The formidable challenges of cross-border enforcement, the evidential hurdles posed by pseudonymity, the conceptual difficulty of fitting digital assets into analogue rules, and the sheer scale of the enforcement task mean that the regime is not a panacea. It will not eradicate market abuse, nor will it insulate investors from the high risks intrinsic to cryptoassets.
Ultimately, the new market abuse regime should be viewed as a vital, but incomplete, part of the regulatory puzzle. Its success will be a measure not just of the rules themselves, but of the FCA’s agility, its technological prowess, and the UK’s commitment to international cooperation. The regime will likely lead to a more professionalised and sanitised domestic crypto market, which is a key component of safety. However, it will not, by itself, make the volatile and global world of digital finance ‘safe’. True safety remains an aspirational goal, one that will require continuous and coordinated effort on legal, technological, and educational fronts, far beyond the scope of this single, albeit crucial, piece of regulation.
