In Argentina, Turkey, and Nigeria, the local currency is not a reliable store of value. The Argentine peso lost roughly 50% of its purchasing power in 2024. The Turkish lira has depreciated by more than 80% against the dollar over five years. The Nigerian naira fell 70% after the 2023 float. Against that backdrop, a dollar-pegged token reachable from a smartphone carries genuine appeal — not as speculation, but as a way to preserve what was earned.
Argentina alone processed $34 billion in stablecoin transactions in 2024, with 67% representing cross-border flows partly designed to circumvent capital controls. Nigerian USDC volume exceeded $3 billion per month in 2025 according to BCG data. The USDT/lira trading pair topped Binance's global volume charts at $22 billion in 2024. These are not marginal flows.
Whether holding stablecoins is safe in any of these contexts depends on three separate questions: which stablecoin, held how, and where.
Why dollars on-chain appeal where bank dollars don't
Official dollar access in many emerging markets is restricted, costly, or rationed. Argentina imposed strict capital controls throughout much of 2023–2025 that limited dollar purchases and set official exchange rates well below the parallel market. Nigeria's central bank tightly managed dollar access until the 2023 float, with persistent shortfalls for businesses and individuals.
For anyone outside the formal banking system — and in Sub-Saharan Africa, a large share of adults are — a bank dollar account requires documentation, a branch, and minimum balances that many people do not have. A stablecoin wallet requires a phone and a data connection.
The result is practical dollar substitution: people earn in local currency, convert to stablecoins at the parallel or post-reform rate, and save in stablecoins denominated in dollars. They transact locally in local currency and hold surplus in stablecoins.
What the stablecoins actually are
The two most widely used stablecoins in emerging markets are structurally different.
USDT (Tether) is issued by Tether Limited, a private company registered in the British Virgin Islands. It holds dollar reserves backing its ~$140 billion in supply, but publishes quarterly attestations rather than monthly audited reports, and its reserve composition has historically included assets other than cash and Treasuries. Tether has maintained its peg through every major stress event since 2017, including the Terra/Luna collapse in 2022 and the FTX failure, which supports confidence in the short term. The longer-term concern is reserve opacity: if Tether's reserves include assets that lose value sharply, the peg is exposed.
USDC (Circle) is issued by Circle, a US-regulated money transmitter. Circle publishes monthly attestations conducted by Deloitte and holds reserves exclusively in cash and short-term US Treasury securities managed through regulated fund structures. USDC is audited more transparently than USDT, but its smaller market share means thinner liquidity in some emerging-market trading pairs.
For a savings application where you hold stablecoins for months, the reserve quality difference between USDC and USDT matters more than it does in a payment context where the token is in your wallet for hours.
Custodial vs self-custody: different risk profiles
Custodial holding (via an exchange like Binance, or an app like Bitso, Flutterwave's Send App, or Felix) means the platform holds the private keys. Your stablecoins are a claim on the platform, not directly on-chain assets you control. If the platform fails — as FTX did in 2022, erasing billions in customer funds — recovery is uncertain. If local regulators compel the platform to freeze accounts, they can. The benefit is simpler access: no seed phrase management, familiar interface, often built-in FX conversion.
Self-custody (holding stablecoins in a wallet where you control the private keys) means no intermediary can freeze or seize the funds — but a lost seed phrase or compromised device means permanent, unrecoverable loss. There is no "forgot my password" for a self-custody wallet. Self-custody requires meaningful technical competence and disciplined backup practices.
For most users in emerging markets, the realistic choice is custodial — through apps that have done the key management work. This is fine if the platform is regulated and reputable, but it does reintroduce intermediary risk.
The specific risks
Depeg risk. A stablecoin can lose its dollar peg. TerraUSD (UST) collapsed entirely in 2022, taking holders' savings to near zero. USDC briefly depegged to $0.88 in March 2023 after Silicon Valley Bank froze $3.3 billion of Circle's reserves — it recovered within days, but anyone who sold at the bottom lost 12%. USDT has never had a material depeg, but its reserves carry less transparency. Fiat-backed stablecoins like USDC and USDT are far more stable than algorithmic designs, but "far more stable" is not "no risk."
Regulatory risk. Several governments have moved to restrict stablecoin use — including some of the same countries where demand is highest. Nigeria's CBN initially banned banks from facilitating crypto transactions in 2021 (later reversed). Countries can and do change the rules. In a custodial app, those rule changes translate quickly to frozen accounts.
FX conversion risk. Getting into and out of stablecoins in many emerging markets means using local on- and off-ramp services that charge fees and set their own rates. In a currency with thin liquidity, the spread between the buy and sell rate can be 2–5%, which erodes the value of holding stablecoins if you convert frequently.
Counterparty risk in the issuer. Stablecoins are not FDIC insured, not regulated as bank deposits, and not guaranteed by any government. They are the liability of the issuer. If Circle or Tether were to fail, holders' claims would depend on bankruptcy proceedings, not deposit insurance.
Self-custody key loss. Irreversible and common. There is no estimate of total funds lost to lost keys that is reliable, but it is a non-trivial share of total stablecoin supply.
A practical risk framework
| Risk | Custodial holding | Self-custody |
|---|---|---|
| Platform failure | High concern | No exposure |
| Regulatory freeze | High concern | Lower concern |
| Depeg | Same for both | Same for both |
| Key loss | Platform's problem | Your problem |
| FX conversion | Managed by platform | Your problem |
| Technical complexity | Low | High |
Neither option is risk-free. The appropriate choice depends on the amount held, technical comfort, and the regulatory environment in the specific country.
What makes it safer
Choose transparent issuers. For long-term savings, USDC's published reserve attestations provide more assurance than USDT's. The difference in liquidity may matter less than the difference in transparency for a savings balance held for months.
Avoid algorithmic stablecoins entirely. For savings in emerging markets, fiat-backed stablecoins from regulated issuers are the only category to consider. The collapses of algorithmic designs wiped out savings that could not be recovered.
Use regulated platforms. Flutterwave, Bitso, Felix, and similar regulated fintech apps provide custodial access with more regulatory oversight than offshore or unregulated exchanges. Regulation does not eliminate risk, but it changes recourse options.
Understand the off-ramp before you on-ramp. The ability to convert stablecoins back to local currency at a reasonable cost when needed is as important as the ability to buy in. In some corridors, off-ramps are thin or expensive. Know what the friction looks like before parking significant savings.
The pattern across markets
IMF and BIS research published in 2026 documented that stablecoin demand in emerging markets correlates strongly with periods of local currency stress — dollar stablecoins are rising more in countries with higher inflation and weaker currencies. Standard Chartered estimated that dollar-backed stablecoins could draw $1 trillion from emerging-market banking systems within three years as adoption scales.
That scale of adoption creates its own systemic questions — what it does to local monetary policy, local banking systems, and exchange rates. But for an individual in Nairobi or Buenos Aires deciding where to hold this month's savings, the systemic question is secondary to the practical one. For them, stablecoins are already functioning as a dollar savings tool — imperfect, with genuine risks, but meaningfully better than local currency inflation in the right conditions.
