The preceding articles in this series have illuminated the profound challenges posed by the inevitable dollarisation of non-US economies through agentic US dollar stablecoins. The impending legal tender status of agentic US dollar, its inherent competitive advantages and the accelerating adoption by autonomous AI agents, threaten to erode monetary sovereignty, destabilise national debt markets and undermine fiscal autonomy. This article proposes a strategic, proactive solution: the issuance of sovereign “double-backed” US dollar stablecoins by state treasuries. These digital instruments would be GENIUS-compliant, that is, maintaining a peg to the US dollar by being backed by US Treasuries whilst simultaneously being collateralised by tokenised property. This innovative model allows nations to leverage their most enduring asset (real estate) to generate yield, preserve national wealth and reclaim a degree of financial independence in a dollarised digital world.
Meanwhile, the global monetary system is entering a new phase - US dollar stablecoins, increasingly designed for AI-driven transactions and backed by US Treasuries, combine the world’s reserve currency with programmable, internet-native payments. As businesses and AI agents optimise for speed, liquidity and yield, digital dollars could increasingly become the preferred settlement asset for global commerce. For many countries, attempting to resist this shift may prove less effective than adapting to it. This article also explores an alternative approach: a sovereign, US dollar-denominated stablecoin backed not only by high-quality liquid assets but also by tokenised domestic property. Rather than competing directly with digital dollars, such a model could align global demand for dollar-denominated digital assets with domestic wealth creation. The objective is to preserve fiscal resilience, attract capital, unlock new funding sources and ensure that, as finance becomes increasingly digital, a greater share of the economic value generated remains within the issuing jurisdiction rather than flowing offshore.
The “Pearl Harbour” of dollarisation
China’s reclassification of the digital renminbi from digital cash to interest-bearing deposit money raises a broader question: how long before the US grants similar legal recognition to AI-native US dollar stablecoins? If that were to happen, digital dollar adoption could accelerate rapidly rather than incrementally, so reshaping payment preferences and cross-border capital flows. As AI agents increasingly optimise transactions for liquidity, yield and settlement efficiency, they may favour dollar-denominated digital assets, potentially increasing the international role of the US dollar in ways that differ from previous periods of dollarisation. For other countries, the implications extend beyond payments. If households, businesses and institutional investors increasingly hold digital dollars rather than domestic assets, then demand for local bank deposits and government bonds could weaken whereby increasing funding costs for both banks and sovereign debt markets. Conventional policy responses, including non-yield-bearing CBDCs or tighter capital controls, may prove less effective in an environment where digital assets are globally accessible. Therefore, the challenge for policymakers is not simply to issue a digital currency but to develop digital assets that combine stability, programmability and economic incentives whilst supporting domestic financial resilience.
The double-backed stablecoin: a paradigm shift
A possible response is a double-backed sovereign stablecoin. The model combines two forms of collateral: US Treasuries and tokenised domestic assets. The first provides a US dollar peg and compliance with emerging US stablecoin standards, so allowing the asset to offer the liquidity, stability and yield increasingly associated with digital dollars. The second anchors part of the stablecoin’s value to national wealth through tokenised government-owned property, infrastructure or other income-producing real-world assets. The concept is certainly not entirely new: in 1696, England’s National Land Bank proposed issuing money backed by landed estates rather than precious metals. Although unsuccessful at the time, modern blockchain infrastructure now allows illiquid assets to be fractionalised, tokenised and managed programmatically in ways that were previously impossible. For governments, tokenised property could unlock dormant public assets whilst generating additional revenue to support a sovereign digital currency; rather than viewing property solely as collateral for borrowing, it becomes part of the monetary infrastructure itself. This creates a powerful economic incentive for holding the sovereign stablecoin. By linking the stablecoin to tangible national assets, the issuing state provides an intrinsic, non-fiat-based layer of value. It also strengthens the stablecoin’s credibility and provides a mechanism for national wealth preservation, even in a dollarised environment. The income generated from tokenised property (as property titles are used as a form of payment) could potentially provide a stable, non-tax revenue stream for the state, therefore enhancing fiscal resilience and reducing reliance on traditional borrowing or taxation especially in the face of declining seigniorage.
Implementation framework: from concept to reality
Implementing a double-backed sovereign US dollar stablecoin collateralised by tokenised property requires a comprehensive framework encompassing legal, technical and economic considerations. The first step involves establishing a robust legal and regulatory framework and would require:
• property rights tokenisation - legislation to legally define and recognise the tokenisation of property rights, so ensuring that digital tokens represent verifiable and enforceable claims on underlying physical assets.
• stablecoin issuance authority - granting a state entity (e.g., HM Treasury or a specially created public corporation) the authority to issue and manage the double-backed stablecoin, including holding US Treasury reserves and managing the tokenised property portfolio.
• GENIUS Act alignment - ensuring the stablecoin’s structure and reserve management practices are fully compliant with the anticipated US GENIUS Act requirements for US dollar stablecoins, so facilitating its acceptance in the broader agentic US dollar ecosystem and being in line with the US-UK transatlantic digital asset collaboration.
• investor protection - establishing clear rules for investor protection, dispute resolution and the governance of the tokenised property assets.
A sovereign double-backed stablecoin would require secure blockchain infrastructure, audited smart contracts, reliable data oracles for real-world asset valuations and income and interoperability with existing payment networks. Governance would be equally important, with transparent reserve management covering both US Treasuries and tokenised domestic assets, automated yield distribution and independent oversight to maintain confidence. The commercial objective is straightforward - by combining the global liquidity of the US dollar with income-generating national assets, governments could create a competitive digital settlement asset whilst retaining more domestic liquidity. This could help support demand for sovereign debt, unlock value from underutilised public assets and provide businesses with a programmable, yield-bearing digital currency. The broader question is whether national balance sheets should become part of the infrastructure supporting money in the digital economy, rather than simply financing government borrowing.
Unsurprisingly, the real estate market is huge - according to Savills, it is valued at over $393trillion, of which $286 trillion is in the form of residential property. Tokenising property allows the state to monetise previously illiquid (or as the French refer to real estate) unproductive assets, so enhancing national wealth in a digital format. It also provides a mechanism for citizens to directly participate in the economic benefits of national assets. A double-backed stablecoin would seek to combine the global liquidity of the US dollar with the value of tokenised national assets. For businesses and AI-driven payment systems, it offers a programmable, yield-bearing settlement asset that aligns international acceptance with domestic economic interests. The model could also broaden governments’ policy toolkit. Smart contracts may enable more efficient fiscal transfers, tax collection and public spending, whilst tokenised public assets could create new sources of revenue and collateral. However, implementation would require clear legal frameworks, robust governance, resilient technology and public confidence. The central question is whether governments can modernise sovereign money quickly enough to compete in an increasingly borderless, AI-driven financial system, or whether digital capital will increasingly migrate to privately issued alternatives.
The future of sovereign finance
Undoubtedly, the rise of agentic US dollar stablecoins marks a watershed moment in global finance, presenting non-US economies with an unprecedented challenge to their monetary and fiscal sovereignty. The “Pearl Harbour event” of legal tender status, coupled with the AI mandate for efficient, risk-free digital assets, threatens to drain national liquidity, destabilise debt markets and usher-in an era of economic vassalage. However, this challenge also presents an opportunity for profound innovation: the “double-backed” sovereign US dollar stablecoin, combining the stability and global acceptance of a GENIUS-compliant US dollar peg with real estate. Such a model allows nations to strategically embrace dollarisation on their own terms, transforming illiquid real estate into programmable, yield-bearing collateral. It provides a pathway to reclaim fiscal autonomy, generate new revenue streams, preserve national wealth and build economic resilience in the digital age. The future of sovereign finance lies not in resisting the inevitable but in intelligently adapting to it, so leveraging cutting-edge technology to redefine the very nature of national money and wealth. For bankers and policymakers, the question is no longer whether stablecoins will become part of mainstream finance, but who will issue the digital money that attracts global capital. If AI agents increasingly optimise for liquidity, yield and regulatory certainty, capital allocation may become an automated decision rather than a human one. Countries that fail to offer competitive digital settlement assets risk seeing deposits, payments and savings migrate to foreign-issued digital dollars, with implications for bank funding, sovereign debt markets and monetary policy.
The opportunity extends beyond digital payments - national balance sheets contain trillions of dollars of underutilised assets (particularly real estate) that could be tokenised and incorporated into the next generation of financial infrastructure. The question is no longer simply whether governments should digitise money, but whether they should also digitise the assets that underpin it. A double-backed stablecoin would allow holders to benefit from the liquidity and stability of US Treasury-backed reserves whilst also gaining exposure to tokenised real estate, an asset class that has historically provided longer-term protection against inflation. As the UK’s own history demonstrates, property has previously played a role in monetary innovation. Blockchain technology and tokenisation now provide the technology to revisit that concept. The jurisdictions that move first may do more than modernise payments; they could reshape how national assets are financed, monetised and preserved in an increasingly AI-driven global economy.
