The market for stablecoins has matured beyond a single yield environment. Treasurers at mid-market companies now face a fragmented yield curve that varies materially by collateral type: fiat-backed, commodity-backed and algorithmic. Each category carries distinct risk profiles, liquidity characteristics and regulatory treatment. The result is a basis risk that complicates cash management strategies and demands more sophisticated treasury operations.
The Fragmented Yield Landscape
Fiat-backed stablecoins such as USDC and USDT offer yields that track short-term US Treasury bills, typically in the range of 4-5% annualised as of early 2025. These instruments benefit from deep liquidity, established redemption mechanisms and a growing regulatory framework in jurisdictions such as the EU under MiCA and in parts of the US. Their yields are relatively predictable and correlate closely with conventional money market rates.
Commodity-backed stablecoins, often pegged to gold or other precious metals, present a different yield profile. Their returns are tied to the underlying commodity price movements plus any storage or custody fees. For a treasurer, this introduces commodity price volatility into what is nominally a cash-equivalent holding. Yields can be negative in real terms when storage costs exceed price appreciation, or positive during commodity bull markets. The yield curve here is not a function of duration but of commodity spot and futures curves.
Algorithmic stablecoins, which maintain their peg through smart contract mechanisms rather than direct collateral, offer the widest yield dispersion. Some protocols have offered annualised yields above 20% during periods of high demand for leverage, but these returns come with acute basis risk. The yield is often paid in the protocol's own governance token, creating a correlation between yield and token price that can amplify losses during a de-pegging event.
Basis Risk in Practice
Basis risk arises when a treasurer holds one type of stablecoin but the company's liabilities or operational expenses are denominated in another. For example, a firm that holds USDC for payroll but receives revenue in a gold-backed stablecoin faces a mismatch that can erode margins if the gold price falls or if the algorithmic stablecoin used for short-term lending de-pegs.
Mid-market treasurers typically lack the dedicated derivatives desks that large corporates use to hedge such exposures. They rely on simple conversion strategies, often through centralised exchanges or OTC desks, which introduce counterparty risk and execution slippage. The cost of hedging basis risk via futures or options on stablecoin pairs can exceed 100 basis points annually, eroding the yield advantage of higher-return stablecoins.
Liquidity and Redemption Dynamics
Liquidity varies significantly across stablecoin types. Fiat-backed stablecoins benefit from direct redemption with the issuer, though this can take 1-3 business days and may be subject to minimum thresholds. Commodity-backed stablecoins often require physical delivery of the underlying asset, which is impractical for most corporate treasurers. Algorithmic stablecoins rely on secondary market liquidity, which can evaporate during stress events.
A treasurer managing a cash portfolio of, say, £5 million must consider not only the yield but the ability to exit the position quickly. The basis risk between stablecoin types becomes acute during market dislocations, when liquidity premiums spike and redemption gates may be activated. The TerraUSD collapse in 2022 demonstrated that algorithmic stablecoins can lose their peg rapidly, leaving holders with significant losses.
Regulatory Divergence
Regulatory treatment of stablecoins is not uniform. The EU's Markets in Crypto-Assets Regulation (MiCA) imposes strict requirements on fiat-backed stablecoin issuers, including reserve composition and redemption rights. Commodity-backed stablecoins fall under different regulatory categories depending on whether they are classified as e-money, commodity derivatives or collective investment schemes. Algorithmic stablecoins face the most regulatory uncertainty, with several jurisdictions considering outright bans or severe restrictions.
For a mid-market treasurer, this regulatory fragmentation creates compliance risk. Holding a stablecoin that is later classified as an unregistered security could trigger reporting obligations, tax penalties or legal exposure. The cost of compliance monitoring and legal advice adds to the total cost of holding each stablecoin type, further widening the effective yield differential.
Commercial Impact
The commercial impact for mid-market firms is twofold. First, the yield differential between stablecoin types can be material. A treasurer who allocates £5 million to a fiat-backed stablecoin yielding 4.5% earns £225,000 annually. Switching to an algorithmic stablecoin yielding 15% would generate £750,000, but with substantially higher risk of principal loss. The basis risk between the two positions, if unhedged, could wipe out the additional yield in a single de-pegging event.
Second, the operational complexity of managing multiple stablecoin types increases treasury overhead. Mid-market firms typically have lean finance teams. Adding stablecoin yield optimisation to their responsibilities requires new skills, systems and counterparty relationships. The cost of this infrastructure can offset yield gains for portfolios below a certain threshold, estimated by some practitioners at £10 million.
Risks and Unknowns
Several risks remain poorly understood. The correlation between stablecoin yields and traditional money market rates is not stable. If central banks cut rates sharply, fiat-backed stablecoin yields will fall, potentially pushing treasurers toward higher-yielding but riskier alternatives. The basis risk between stablecoin types may widen during such transitions.
Regulatory action remains the largest unknown. A coordinated global crackdown on algorithmic stablecoins could eliminate that yield category entirely. Conversely, regulatory clarity for fiat-backed stablecoins could narrow the yield spread as more capital enters the space. The timing and direction of regulatory changes are difficult to predict.
Counterparty risk at exchanges and custodians is another concern. Several major platforms have failed or faced liquidity crises. Treasurers must assess the creditworthiness of the entities through which they access stablecoin yields, adding another layer of due diligence.
FY Outlook
The stablecoin yield curve will likely remain fragmented for the foreseeable future. Fiat-backed stablecoins will continue to offer low but predictable returns, closely tied to monetary policy. Commodity-backed stablecoins may gain traction among firms with natural exposure to commodity prices, such as miners or agricultural producers. Algorithmic stablecoins will persist but remain a niche product for sophisticated investors willing to accept tail risk.
Mid-market treasurers should expect the basis risk between stablecoin types to persist and potentially widen. The most prudent approach is to treat stablecoin cash management as a distinct asset class with its own risk budget, separate from traditional cash and short-term fixed income. Firms with less than £10 million in cash holdings may find that the operational costs of yield optimisation outweigh the benefits.
Conclusion
The stablecoin yield curve is not a single curve but a family of curves, each with different risk, liquidity and regulatory characteristics. Mid-market corporate treasurers must navigate this complexity with limited resources. The decision to hold one stablecoin type over another is not merely a yield optimisation exercise but a risk management decision with material commercial consequences. Those who treat stablecoins as interchangeable cash equivalents do so at their peril.

Why It Matters
Mid-market corporate treasurers are increasingly allocating cash to stablecoins for yield, but the divergence in risk profiles across fiat-backed, commodity-backed and algorithmic instruments creates basis risk that can erode returns and introduce principal loss. Understanding this disconnect is essential for prudent cash management.
