Last week, the Office for Budget Responsibility (OBR) released a sobering update on the long-term outlook for UK public finances, painting a challenging fiscal future shaped by an ageing population, climate change costs, and infrastructure demands. The report projects a significant decline in demand for UK government debt—gilts—by domestic pension schemes, from nearly 30% of GDP (around £1 trillion) to just 11% by 2050, with half of this decline expected within the next five years. This fall is primarily driven by the ongoing decline of final salary (defined benefit) pension schemes, which traditionally held gilts to match pension liabilities, and the rise of defined contribution schemes, which lessen the need for such assets.

This shift is far from a niche technical issue; it holds major implications for the UK government’s cost of borrowing. With fewer pension schemes demanding gilts, prices for government debt could remain depressed and interest rates elevated, potentially increasing the government’s annual interest payments by as much as £22 billion. Such an increase would divert public funds from essential services like health and education, compounding the fiscal pressures faced by a government already borrowing over £100 billion annually.

Attempts to address this by pushing pension funds towards infrastructure and private assets while also requiring more gilt holdings risk contradictory policy goals and exacerbate investor fears of financial repression. Meanwhile, calls to reduce overall debt issuance face political hurdles and the reality of an electorate weary of tax hikes and spending cuts. The broader OBR fiscal risks report warns of a ‘daunting’ set of challenges, including growing state pension costs—which may rise from nearly 5% to 7.7% of GDP by 2070—and sluggish productivity growth, all converging to imperil the UK’s fiscal flexibility and economic stability.

Against this backdrop, some have turned to more innovative financial solutions, notably stablecoins. These digital currencies are typically pegged to low-risk assets such as short-term government debt or cash and are backed by blockchain technology, offering stability combined with programmability. In theory, the development of a UK stablecoin ecosystem—backed partly by gilts or similar sovereign debt—could help spur demand for UK government assets while modernising the financial system.

Yet the UK lags behind other global financial hubs, particularly the United States, where regulatory clarity on stablecoins is advancing rapidly. The US Treasury has signalled stablecoin legislation as a key priority, exemplified by the imminent passage of the Genius Act, which will provide clearer rules for firms issuing dollar-backed stablecoins. US companies such as Circle Internet—the issuer of USD Coin—have seen soaring investor enthusiasm, reflecting confidence in digital currencies tied to stable assets. This US momentum contrasts with the more cautious stance of the Bank of England governor, Andrew Bailey, who recently voiced concerns about stablecoins’ risks to monetary policy transmission and financial stability. His focus on tokenised reserves tied closely to the domestic banking system could limit the UK’s potential to become a global leader in digital finance.

Looking internationally, countries including China, Singapore, and the European Union are racing ahead with their own stablecoin or central bank digital currency projects, positioning digital finance as a geopolitical battleground where the UK risks falling behind.

Aside from macroeconomic considerations, stablecoins may also offer solutions to domestic challenges such as financial inclusion. With high street bank closures and declining cash usage leaving some populations unbanked or underbanked, stablecoins accessible via smartphones could provide low-cost, reliable digital payment options. This could empower marginalised groups, gig economy workers, and small businesses that currently struggle with traditional banking.

There are, however, important regulatory and stability concerns. The Bank for International Settlements has warned that stablecoins pose risks to financial stability and monetary sovereignty if not properly regulated, pointing out issues including their exclusion from banking know-your-customer rules and potential to disrupt safe asset markets. The UK’s Financial Conduct Authority has taken tentative steps toward loosening restrictions on certain crypto investment products, reflecting a cautious but evolving attitude, with broader regulatory frameworks for digital assets—including stablecoins—still in development under government oversight.

Meanwhile, the tokenisation of assets such as Treasury funds has gained traction in the crypto sector, with institutional players increasingly investing in tokenised mutual funds and bonds. These products offer improved liquidity and faster settlement timeframes, appealing to crypto investors who seek yield and operational efficiency. Market projections suggest that tokenised financial products could reach trillions in value, underscoring the transformative potential of digital assets.

For the UK, embracing stablecoins and other digital financial innovations could not only help modernise its financial system but also maintain demand for sterling-denominated sovereign debt amid changing investor behaviour. However, without a clear and supportive regulatory framework, the UK risks missing out on these opportunities, exacerbating existing fiscal challenges, and ceding ground to more proactive global competitors.

The government faces the complex task of balancing innovation with financial stability, ensuring that digital assets bolster rather than undermine public finances. The evolving stance of both the Bank of England and Chancellor Rachel Reeves, especially in forthcoming statements such as the Mansion House speeches, will be crucial in signalling the UK’s direction in this fast-changing financial landscape. In this digital finance race, the UK’s ability to act decisively could shape its economic resilience and global standing for decades.
