BoE speech frames the practical hurdles for tokenisation and digital assets

# What Mills said and why it matters

Mills identifies the concrete legal and operational questions that must be answered before tokenisation and smart contracts can scale: who owns a token, which record is authoritative, how settlement finality is achieved, how insolvency is handled, who is accountable, and where the regulatory perimeter lies. These are practical questions that determine whether market participants will accept and depend on token-based systems.

# Concrete market tools under development

May and promised a full Roadmap later in the year. Mills points to active, testbed-style tools that feed policy design: the Digital Securities Sandbox lets firms trade with real customers under predefined limits (for example, quoted limits for gilts of £8–13.1 billion) and now permits stablecoins as a settlement asset. These controlled experiments are intended to shape future permanent rules for central securities depositories and settlement finality.

# The BoE's stated commitments

Mills sets out five commitments the BoE will pursue alongside market participants:

• Stay neutral on technology while assessing practical outcomes.
• Support experimentation and scaling through sandboxes and other test environments.
• Improve the BoE's own processes to work with new platforms and instruments.
• Back a Digital Markets Champion to improve market connectivity and coordination.
• Work with domestic and international authorities to reduce fragmentation.

For each commitment, Mills challenges industry to invest, collaborate and demonstrate that commercial value can be delivered safely and at scale.

# Why coordination and legal foundations are central

Mills makes a direct point: tokenisation will not succeed through isolated technical fixes. It needs coordinated change across participants, interoperable systems that can exchange assets and information reliably, and firm legal foundations so market users know which records and promises they can rely on. Without that combination, technical experiments will not convert into mainstream market infrastructure.

# What to watch next

Expect the BoE/FCA Roadmap to add specificity on the regulatory perimeter, settlement finality rules and how existing legal frameworks should treat tokenised assets. Watch the Digital Securities Sandbox outputs and any follow-up proposals for central securities depositories or changes to settlement law. The live synchronisation service timeline (2028) provides a marker for when settlement-in-central-bank-money options might become operational for new platforms.
