For more than a decade, stablecoins have been sold as the financial world’s answer to volatility: digital tokens that promise the speed and programmability of cryptocurrencies without the stomach-churning price swings. Pegged to the US dollar or other supposedly safe assets, they are marketed as the dependable plumbing of a new, frictionless financial system. Yet as their market value has ballooned into the hundreds of billions, so too have the questions about what really lies beneath this veneer of stability.
From opaque reserves and regulatory gray zones to the uncomfortable reality that many “stable” coins have broken their pegs at critical moments, the sector’s foundations look far less solid than the branding suggests. London Business School’s latest research cuts through the marketing gloss to examine whether stablecoins truly reduce risk-or simply repackage it in a more reassuring form. In a world hungry for digital money that can be trusted, understanding the illusion-and the limits-of stability has never been more urgent.
Unmasking the promise of digital dollars Why stablecoins feel safe but remain structurally fragile
From the outside, tokens pegged 1:1 to the dollar look like a digital safe harbour: prices barely move, apps show a reassuring “$1.00”, and marketing materials lean heavily on words like “cash-equivalent” and “fully backed”. Yet beneath this calm surface lies a structure that more closely resembles a lightly regulated money-market fund than a bank deposit. Reserves frequently enough sit in a mix of short-term government debt, bank deposits and commercial paper, instruments that can become illiquid or lose value under stress. Redemption promises are also conditional: issuers can halt withdrawals, impose delays or change terms. In moments of market panic, those caveats matter more than any glossy assurance on a website.
What makes these tokens feel safe is not just the peg, but a narrative carefully built around them. Issuers highlight:
- Familiar anchors – the US dollar, Treasuries, cash-like assets
- Simple stories – “every token is backed by one real dollar”
- Everyday use cases – payroll, remittances, cross-border trade
| Perception | Reality Check |
|---|---|
| Digital cash in your wallet | Claim on a private issuer’s balance sheet |
| Always redeemable at $1 | Redemptions can be paused, gated or repriced |
| Risk-free store of value | Exposed to market, liquidity and legal risks |
This gap between image and infrastructure creates a structural fragility: stability depends not only on collateral quality and regulation, but also on confidence that can evaporate in a single trading day.
Inside the peg How governance opacity and collateral quality undermine perceived stability
Behind the reassuring promise of a one-to-one peg lies a governance structure that is often anything but transparent. Many issuers publish glossy reserve reports while revealing little about decision-making processes, conflict-of-interest management or who ultimately controls emergency levers such as redemption gates or blacklisting powers. In practice, the “stability” investors perceive is frequently outsourced to a small circle of insiders and service providers, from custody banks to market makers. This opacity matters because when pressure builds, users suddenly discover they are relying on a patchwork of legal agreements, discretionary policies and off-chain relationships rather than a clear, enforceable claim.
The quality and composition of collateral amplify these hidden risks. A stablecoin may be fully “backed” on paper, yet still fragile if reserves are concentrated in illiquid or volatile assets. Short-term government debt, commercial paper and even crypto-backed loans can move sharply in value during market stress, turning a safe-looking peg into a confidence game. Key warning signs include:
- Vague reserve disclosures with broad asset buckets and no look-through to underlying holdings.
- Heavy reliance on correlated assets such as other stablecoins or crypto tokens as collateral.
- Redemption restrictions that appear only in footnotes or legal fine print.
- Unclear audit scope, where “attestations” replace full, independent audits.
| Collateral Profile | Perceived Stability | Hidden Vulnerability |
|---|---|---|
| Cash & T-bills | High | Concentration in few banks |
| Corporate paper | Moderate | Credit & rollover risk |
| Crypto collateral | Innovative | Price crashes & liquidity gaps |
| Other stablecoins | Comforting | Contagion & circular backing |
When stability breaks Systemic risks for markets consumers and regulators in a run on stablecoins
Once confidence in a major digital coin evaporates, the promised peg can unravel in minutes, turning a niche tech product into a mainstream financial shock. A rapid sell-off forces issuers to liquidate their reserves, often in highly correlated assets such as short-term government bonds or commercial paper. This can transmit stress into traditional markets, especially when redemptions are large and simultaneous. Liquidity dries up,spreads widen,and even solvent institutions can be dragged into distress. For ordinary users,what looked like a frictionless digital cash substitute morphs into a classic bank run with a modern user interface: apps freeze,withdrawal windows close,and the value of supposedly stable balances falls below par. The bigger the ecosystem built on top of these tokens-DeFi protocols, trading venues, consumer payments-the more complex the contagion pathways become.
The regulatory dilemma is equally stark. Supervisors must decide in real time whether to treat these issuers as banks, money-market funds, or something entirely new, often with incomplete data and intense political pressure. Delayed action can amplify losses; heavy-handed intervention can cement moral hazard.Key stakeholders feel the strain in different ways:
- Retail consumers face sudden loss of savings and payment disruptions.
- Institutions suffer forced asset sales and mark-to-market hits.
- Regulators risk credibility if they appear captured or unprepared.
- Developers and platforms confront legal liability and reputational damage.
| Actor | Immediate risk | Long-term impact |
|---|---|---|
| Consumers | Loss of funds | Lower trust in digital finance |
| Banks & funds | Market volatility | Higher funding costs |
| Regulators | Crisis management | Expanded oversight mandates |
Building real resilience Policy safeguards institutional standards and investor due diligence for a post illusion era
As the myth of frictionless digital dollars frays, regulators and investors are beginning to treat these instruments less like harmless plumbing and more like systemically relevant shadow banks. That shift demands a new toolkit: capital and liquidity rules that bite in stress scenarios,ring-fenced reserves held in bankruptcy-remote structures,and mandatory,independent audits that trace every major asset and liability on a near-real-time basis. Equally vital is a common vocabulary: standardised risk labels, clear disclosure templates and comparable stress tests that make it harder for marketing gloss to obscure concentrated bets on short-term credit, thin liquidity, or opaque counterparties. In this landscape, “trust me” gives way to “show me”, and disclosure becomes an ongoing process rather than a glossy PDF buried in a website footer.
Institutional investors, too, are rewriting their playbooks, moving beyond headline peg stability to interrogate governance, operational resilience and the incentives of founding teams. Due diligence now extends to:
- Governance structure – board independence, veto rights and conflict-of-interest policies.
- Reserve composition – share of cash versus short-term paper, concentration of bank custodians.
- Redemption mechanics – speed, gates, fees and historical performance under stress.
- Regulatory perimeter – licences held, supervisory regime and enforcement track record.
| Focus Area | Old Illusion | Resilience Standard |
|---|---|---|
| Reserves | “Fully backed” marketing claims | Verified, audited asset breakdown |
| Liquidity | Assumed 24/7 convertibility | Modelled and tested stress redemptions |
| Governance | Founder-controlled structures | Independent oversight with clear duties |
| Clarity | Sporadic attestation reports | Frequent, machine-readable disclosures |
In Conclusion
the promise of stablecoins is less about stability than about storytelling. They offer the reassuring language of price pegs and technological innovation, yet remain deeply entangled with the same market forces, incentives and vulnerabilities that have long shaped global finance.As regulators in London and beyond weigh how to classify and constrain these instruments, businesses and consumers will need to distinguish between stability as a marketing claim and stability as a structural reality. Until the underlying risks – from collateral opacity to governance failures and regulatory arbitrage – are more fully resolved,stablecoins will continue to occupy an uneasy space: indispensable to the growth of digital finance,but far from the safe harbour their name suggests.
For financial leaders, the task now is not to reject stablecoins outright, but to interrogate their design, scrutinise their backers and understand their systemic implications. Only then can the City of London, and the institutions that operate within it, decide whether these digital tokens are a durable foundation for the future of money – or simply the latest expression of an enduring illusion.
