Stablecoins Explained: Uses, Risks, and Regulatory Considerations for Asset Managers and Family Offices
What the $306 billion market cap data reveals, how major jurisdictions are regulating stablecoins in 2025, and a practical framework for institutional due diligence
Stablecoins crossed a critical threshold in 2025: they became infrastructure. No longer merely instruments for crypto-native trading, they are now settlement rails for cross-border remittances, liquidity substrates for decentralized finance, and increasingly, components of institutional treasury management strategies. For asset managers evaluating digital asset exposure, the question is no longer whether to understand stablecoins, but how to evaluate them with the same rigour applied to money market funds, foreign exchange instruments, or short-duration fixed income.
The market data confirms this evolution. Stablecoin market capitalization reached $306 billion by November 2025, representing a 49% increase from January 2025’s roughly $205 billion base. Transaction volume tells an even more compelling story: $33 trillion in stablecoin transactions executed in 2025 — a 72% year-over-year increase — with USDC and USDT together processing $31.6 trillion ($18.3 trillion and $13.3 trillion respectively). Stablecoins now account for 30% of crypto transaction volume, positioning them as the primary medium of value transfer across digital asset markets.
Understanding stablecoins requires moving beyond the “digital dollar” simplification to evaluate the specific mechanics of reserve backing, redemption guarantees, regulatory compliance, and de-pegging risk that determine whether a stablecoin is suitable for institutional capital.
What Stablecoins Are and How They Function
A stablecoin is a digital token designed to maintain a stable value relative to a reference asset — typically the U.S. dollar, though euro, yen, and commodity-backed variants exist. The mechanism maintaining the peg is collateralisation: the issuer holds reserve assets equivalent to or exceeding the stablecoins issued, with the promise (enforceable to varying degrees) that each token can be redeemed for the underlying reference asset.
The dominant collateralisation models are:
Fiat-backed stablecoins — the largest category by market cap. The issuer holds deposits in bank accounts, short-term government securities (primarily U.S. Treasury bills), and cash equivalents equal to the tokens issued. USDC and USDT, the two largest stablecoins, both operate on this model, with USDC maintaining 100% reserves in cash and Treasury bills with monthly attestations from Grant Thornton.
Crypto-collateralised stablecoins — tokens backed by over-collateralised cryptocurrency positions, typically on-chain and visible in smart contracts. DAI, the largest example, requires collateral worth more than 150% of the stablecoins issued to account for cryptocurrency volatility. These instruments carry fundamentally different risk profiles than fiat-backed alternatives and are predominantly used within DeFi protocols rather than institutional treasury management.
Algorithmic stablecoins — tokens that attempt to maintain peg through algorithmic supply mechanisms rather than explicit collateral backing. The collapse of TerraUSD (UST) in 2022 — which lost its $1 peg and declined to near zero within days — demonstrated the structural fragility of this model. No major algorithmic stablecoin retains significant market share post-2022.
For asset managers, the relevant distinction is between regulated, fully-reserved fiat-backed stablecoins (USDC, PYUSD) and less transparent fiat-backed alternatives (USDT), along with the emerging yield-bearing stablecoins that complicate the traditional reserve model by deploying backing assets into income-generating instruments rather than cash and T-bills.
Uses: Where Stablecoins Create Operational Value
Cross-Border Payments and Treasury Settlement
The primary institutional use case for stablecoins is settlement efficiency. Traditional correspondent banking moves value across borders in 1–5 business days with fees ranging from 1–4% of transaction value plus FX spread. Stablecoin settlement occurs in minutes at costs typically below 0.1% per transaction.
This is not theoretical. Major payment processors including PayPal, Visa, and Mastercard have embedded stablecoin settlement infrastructure into their payment systems in 2025. For treasury operations at multinational companies, the ability to move liquidity across jurisdictions in near-real-time, outside traditional banking hours, represents a material operational improvement over ACH and SWIFT rails.
DeFi Yield and Liquidity Provision
Stablecoins form the base layer of decentralized finance. They account for approximately 40% of DeFi total value locked (TVL) — roughly $49.4 billion as of mid-2025. Institutional-grade yield strategies use stablecoins to provide liquidity to automated market makers, lend on over-collateralised lending protocols, and participate in yield-optimising vaults.
The yield available on stablecoins in DeFi — typically 3–8% annualised for USD-pegged assets — is not risk-free. It reflects counterparty exposure to the lending protocol’s smart contract risk, the collateral quality of borrowers, and the liquidity depth of the underlying market. For asset managers, this yield is comparable to high-grade corporate credit or emerging market sovereign debt in risk-adjusted terms, requiring equivalent due diligence.
Currency Substitution in Emerging Markets
In jurisdictions with currency volatility or capital controls, stablecoins function as dollar substitution instruments. Chainalysis data shows that between June 2024 and June 2025, USDT alone processed roughly $703 billion per month, peaking at $1.01 trillion in June 2025. Much of this volume represents retail and SME usage in emerging markets accessing dollar-denominated liquidity outside local banking systems.
For global family offices with operational exposure to multiple jurisdictions, understanding how stablecoins are used by portfolio companies, local partners, and supply chain counterparties is now a component of operational due diligence — even if the family office does not directly hold stablecoins as portfolio assets.
Risks: What the De-Pegging Events Reveal
The argument that stablecoins are “safe” or “equivalent to cash” fails under stress. Two major de-pegging events in 2023 demonstrate the specific failure modes that institutional investors must model.
USDC De-Pegging: March 2023
On March 11, 2023, USDC — the second-largest stablecoin and widely considered the most institutionally credible — de-pegged from $1.00 to $0.87 on major exchanges. The trigger: Silicon Valley Bank’s failure, which held $3.3 billion of Circle’s $40 billion in USDC reserves.
While Circle maintained reserves exceeding 100% of issued USDC, the reserves were temporarily inaccessible due to bank insolvency. The price decline reflected market uncertainty about whether the Federal Reserve would make depositors whole. USDC returned to $1.00 by March 13 after the Fed announced SVB depositor protection — but the 48-hour de-peg triggered 3,400+ automatic liquidations on DeFi lending protocols and created immediate cash flow crises for corporate treasury teams holding USDC for operational payments.
The lesson: Reserve adequacy is necessary but not sufficient. Reserve * custody* and accessibility during stress determine whether redemption guarantees can be executed when needed.
Tether De-Pegging: June 2023
Tether (USDT) — the largest stablecoin by market cap — experienced a de-peg in June 2023 due to an imbalance in Curve’s 3pool liquidity pool, which holds large amounts of USDT, USDC, and DAI. Unlike the USDC de-peg, which was driven by reserve custody concerns, the Tether event was driven by liquidity pool dynamics — large withdrawals from the 3pool created temporary selling pressure that pushed USDT below its peg.
The distinction matters for risk assessment. Fiat-backed stablecoins face two distinct de-pegging vectors: fundamental (reserve adequacy, issuer solvency, banking relationships) and technical (liquidity pool imbalances, leveraged liquidations, exchange-specific pricing anomalies). Institutional treasuries typically face fundamental risk; trading operations face both categories.
Risk Management Frameworks
Current practitioner guidance suggests:
- Keep stablecoin exposure under 5% of liquid assets for mid-market companies, with daily or weekly conversion to fiat to minimise de-peg exposure
- Set 2% de-peg alerts to trigger immediate review and potential conversion
- Diversify across multiple stablecoins and custody arrangements to avoid single-points-of-failure
- Assume stablecoins are not cash equivalents for accounting purposes — GAAP classification depends on price stability, and de-pegging events may disqualify stablecoins from monetary instrument treatment
Regulatory Landscape: MiCA and GENIUS Act
2025 marked the maturation of stablecoin regulation in major jurisdictions. Two frameworks now define the compliance boundary for institutional use: the EU’s Markets in Crypto-Assets (MiCA) regulation and the U.S. GENIUS Act.
EU MiCA (Effective January 1, 2025)
MiCA is the world’s first comprehensive stablecoin regulatory framework, establishing mandatory requirements for issuers operating in EU jurisdictions:
- 100% reserve backing in segregated accounts
- Monthly third-party attestations of reserve holdings
- Redemption guarantees at par value
- EU-based operational presence for issuers exceeding €5 million daily transaction volume
Circle’s USDC achieved full MiCA compliance in December 2024, securing authorisation to operate across all 27 EU member states. Conversely, Tether’s USDT has not received MiCA approval as of early 2026 due to gaps in reserve attestation and transparency requirements — creating potential delisting risk from EU-regulated exchanges.
For asset managers with EU exposure, the MiCA compliance status of stablecoin holdings is now a mandatory due diligence item. Non-compliant stablecoins may face trading restrictions or outright exclusion from EU-regulated venues.
U.S. GENIUS Act (Passed July 2025)
The U.S. framework evolved more recently with the July 2025 passage of the GENIUS Act, signed following the 2024 U.S. election cycle. The Act establishes:
- Federal authorisation requirement for all payment stablecoin issuers
- Strict reserve requirements ensuring 1:1 backing with liquid assets
- Clarity for institutional investors regarding stablecoin regulatory treatment
The GENIUS Act’s passage has been interpreted by markets as a “green light for digital dollar innovation,” with the regulatory clarity contributing to the 2025 stablecoin market cap expansion. Implementation guidance is expected by early 2026, with existing issuers required to complete licensing and compliance reviews.
Regulatory Divergence and Cross-Border Implications
The EU and U.S. frameworks are not harmonised. MiCA provides a single EU-wide license; the GENIUS Act focuses on the U.S. market alone. Issuers must maintain dual compliance structures to operate across both jurisdictions. The practical implication for asset managers: stablecoin selection must be jurisdiction-specific, with compliance status verified against the regulatory framework applicable to the client’s domicile and operational footprint.
Due Diligence Framework for Institutional Investors
When evaluating stablecoins for portfolio or treasury use, the following verification steps are essential:
Reserve and Custody Verification
- Are reserves held 1:1 in cash and short-term government securities?
- Are reserve attestations provided by a recognised third-party auditor (e.g., Grant Thornton, BDO)?
- How are reserves custodied — bank deposits, direct Treasury holdings, or money market instruments?
- What is the issuer’s banking counterparty concentration? (SVB demonstrated that single-bank custody creates systemic risk)
Regulatory Compliance
- Is the stablecoin MiCA-compliant for EU operations?
- Has the issuer obtained or applied for GENIUS Act authorisation in the U.S.?
- Are there pending regulatory actions or enforcement proceedings against the issuer?
Redemption and Liquidity Mechanics
- What is the minimum redemption size? (USDC permits direct redemption at par; USDT’s $100,000 minimum forces reliance on secondary markets for smaller holders)
- Has the stablecoin maintained its peg through prior stress events? (USDC: March 2023; USDT: June 2023)
- What was the issuer’s crisis communication speed and transparency during de-peg events?
Operational Infrastructure
- What custody and security infrastructure protects the tokens once acquired?
- Is the stablecoin supported by qualified custodians with insurance coverage?
- What are the gas/network fees for transfer and redemption?
