Cross-border payments have long been one of the most expensive and inefficient segments of the global financial system. According to the World Bank's Remittance Prices Worldwide database, the global average cost of sending $200 cross-border remains above 6%, with sub-Saharan Africa being the most expensive region to send money to, averaging 7.8% in fees as of Q4 2024. For B2B payments, SWIFT transfers typically cost $25-50 per transaction and take 2-5 business days to settle through correspondent banking chains.
Stablecoins - digital tokens pegged to fiat currencies like the US dollar - are fundamentally changing this dynamic. By moving value on public blockchain networks rather than through correspondent banking chains, stablecoin settlement offers a compelling alternative: sub-dollar fees, settlement in minutes rather than days and 24/7 availability without reliance on banking hours or intermediary institutions.
What Are Stablecoins?
A stablecoin is a cryptocurrency designed to maintain a stable value relative to a reference asset, typically the US dollar. Unlike Bitcoin or Ethereum, whose values fluctuate significantly, stablecoins are engineered to trade at or very near $1.00 at all times. They achieve this stability through different mechanisms:
- Fiat-backed stablecoins (USDC, USDT): Backed 1:1 by reserves of cash and cash-equivalent assets held in regulated financial institutions. For every token in circulation, the issuer holds $1 in reserves.
- Crypto-collateralized stablecoins (DAI): Over-collateralized by cryptocurrency deposits locked in smart contracts.
- Algorithmic stablecoins: Use supply/demand algorithms to maintain peg (historically less reliable; Terra/UST collapse in 2022 demonstrated the risks).
For B2B settlement purposes, fiat-backed stablecoins - specifically USDC (issued by Circle) and USDT (issued by Tether) - dominate. Combined, they represent over $180 billion in circulating supply as of early 2026, with USDT commanding approximately $130 billion and USDC approximately $55 billion.
How Traditional Cross-Border Payments Work
To understand why stablecoin settlement is transformative, it helps to understand the existing system. A typical cross-border B2B payment through the SWIFT network involves multiple parties:
- Originating bank: The sender's bank initiates the transfer and debits the sender's account.
- Correspondent bank(s): One or more intermediary banks that hold nostro/vostro accounts to facilitate the cross-border movement of funds. A single transaction may pass through 2-4 correspondent banks.
- Beneficiary bank: The recipient's bank credits the receiver's account upon receiving the funds.
Each intermediary in this chain adds time, cost and opacity. Fees accrue at each step. Settlement timing depends on each bank's processing windows, timezone differences and cut-off times. The sender typically has limited visibility into where their payment is in the chain until it arrives (or fails to arrive) at the destination.
Traditional SWIFT transfer: $25-50 in fees, 2-5 business days, limited tracking. Stablecoin settlement: under $1 in fees, under 5 minutes, full on-chain transparency.
How Stablecoin Settlement Works for B2B Payments
Stablecoin settlement replaces the correspondent banking chain with a direct, peer-to-peer value transfer on a public blockchain. The process works as follows:
Step 1: On-Ramp (Fiat to Stablecoin)
The sending party converts their local currency into USDC or USDT through a licensed exchange, OTC desk, or directly through an API provider. For businesses, this typically happens through an institutional on-ramp like Circle's APIs (for USDC) or through regulated crypto exchanges that support corporate accounts.
Step 2: Transfer (Blockchain Settlement)
The stablecoins are transferred from the sender's blockchain wallet to the recipient's wallet. This transfer is executed as a blockchain transaction that settles in seconds to minutes depending on the network used:
| Network | Settlement Time | Typical Fee |
|---|---|---|
| Solana | ~400ms | $0.001-0.01 |
| Tron (TRC-20) | ~3 seconds | $0.50-1.00 |
| Polygon | ~2 seconds | $0.01-0.05 |
| Ethereum (ERC-20) | ~12 seconds | $2-20 (variable) |
| Base | ~2 seconds | $0.01-0.10 |
Step 3: Off-Ramp (Stablecoin to Fiat)
The recipient converts the stablecoins back into their local currency through a local exchange, OTC desk, or off-ramp provider. In African markets, companies like Yellow Card, AZA Finance (formerly BitPesa) and local exchanges facilitate this conversion into currencies like NGN (Nigerian Naira), KES (Kenyan Shilling), or GHS (Ghanaian Cedi).
USDC: Circle's Institutional-Grade Stablecoin
USDC is issued by Circle, a regulated financial technology company based in the United States. Key characteristics of USDC for B2B settlement include:
- Transparency: Monthly reserve attestation reports from Deloitte (since September 2023, previously Grant Thornton). Reserves are held in US Treasury bills and cash deposits at regulated banks.
- Regulatory compliance: Circle is registered as a Money Services Business with FinCEN, holds state-level money transmitter licenses and operates under European MiCA regulation through its French subsidiary.
- Multi-chain support: USDC is natively issued on Ethereum, Solana, Avalanche, Polygon, Base, Arbitrum, Optimism and several other chains.
- Cross-Chain Transfer Protocol (CCTP): Circle's CCTP enables native USDC transfers between supported chains without bridges, reducing counterparty risk.
- API access: Circle provides programmatic APIs for minting, burning and transferring USDC, suitable for enterprise integration.
USDT: Tether's Market-Dominant Stablecoin
USDT is issued by Tether, a company incorporated in the British Virgin Islands. Despite ongoing discussions about its reserve composition, USDT remains the most widely traded stablecoin by volume:
- Market cap: Approximately $130 billion in circulation (early 2026), making it the largest stablecoin by a significant margin.
- Liquidity: USDT is the most liquid stablecoin in African markets, with the highest trading volume against local currencies on exchanges operating in Nigeria, Kenya and South Africa.
- Chain dominance: Tron (TRC-20) accounts for a large share of USDT transfers, particularly for remittance and cross-border commerce in emerging markets, due to low fees.
- Reserve composition: Tether publishes quarterly attestations (BDO Italia) showing reserves comprised primarily of US Treasury bills, with some allocation to secured loans and other investments.
Regulatory Landscape in Africa
The regulatory environment for stablecoins in Africa is evolving rapidly, with different jurisdictions taking different approaches:
South Africa
The Financial Sector Conduct Authority (FSCA) declared crypto assets as financial products under the Financial Advisory and Intermediary Services (FAIS) Act in 2022. Crypto asset service providers must now be licensed. This provides a clear regulatory framework for stablecoin-based settlement services.
Nigeria
The Nigerian Securities and Exchange Commission (SEC) issued rules on digital asset offerings in 2022, establishing a regulatory framework for Virtual Assets Service Providers (VASPs). The Central Bank of Nigeria, which previously banned banks from facilitating crypto transactions in 2021, reversed this position in late 2023, allowing banks to service regulated crypto businesses.
Kenya
Kenya's Capital Markets Authority (CMA) has been developing a regulatory framework for digital assets, with draft guidelines published in 2023. The country has taken a cautious but progressive approach, recognizing the importance of innovation while managing risk.
The overall trajectory across African markets is toward regulation rather than prohibition. Jurisdictions that initially banned crypto are reversing course (Nigeria) while others are building comprehensive frameworks from scratch (South Africa, Kenya). This creates a more favorable environment for stablecoin-based settlement services.
Cost Comparison: SWIFT vs. Stablecoin Settlement
For a $10,000 B2B payment from the United States to Nigeria, the cost comparison is stark:
| Factor | SWIFT/Correspondent Banking | Stablecoin Settlement |
|---|---|---|
| Transfer fee | $25-50 | $0.01-1.00 |
| FX spread | 1-3% | 0.5-1.5%* |
| Intermediary fees | $15-30 (correspondent bank charges) | $0 |
| Settlement time | 2-5 business days | Minutes to hours |
| Availability | Banking hours only | 24/7/365 |
| Tracking | Limited (SWIFT GPI improving this) | Full on-chain transparency |
| Total cost (approx.) | $140-350 (1.4-3.5%) | $50-151 (0.5-1.5%) |
*FX spread on off-ramp depends on local market liquidity. Major markets (Nigeria, Kenya) typically offer tighter spreads than smaller markets.
Use Cases for B2B Stablecoin Settlement
Supplier Payments
Companies importing goods from emerging markets can pay suppliers in stablecoins, which suppliers then convert to local currency. This eliminates the multi-day delays that can disrupt supply chains and reduces the cost of each payment.
Payroll for Distributed Teams
Technology companies with employees across multiple African countries can settle payroll through stablecoins, avoiding the need for separate banking relationships and correspondent banking chains in each country.
Platform Settlements
Marketplace platforms, freelance platforms and gig economy companies can use stablecoins to settle with service providers across borders efficiently, especially for the frequent, lower-value payments that are prohibitively expensive through traditional banking.
Risks and Limitations
Stablecoin settlement is not without risks and limitations that businesses must consider:
- Regulatory uncertainty: While the trend is toward regulation, the landscape remains fluid. Rules can change, potentially restricting certain operations.
- Off-ramp liquidity: In smaller markets, converting stablecoins to local fiat currency may face liquidity constraints, wider spreads, or processing delays.
- Counterparty risk: Both USDC and USDT carry issuer risk. While unlikely, a reserve failure or regulatory action against the issuer could impact token value.
- Operational complexity: Managing blockchain wallets, private keys and smart contract interactions adds technical complexity compared to traditional bank wires.
- Accounting and tax treatment: The tax and accounting treatment of stablecoin transactions varies by jurisdiction and may require specialized guidance.
The Path Forward
Stablecoin settlement is not replacing traditional banking infrastructure overnight. Rather, it is emerging as a complementary rail that excels in specific use cases - particularly cross-border B2B payments to and within emerging markets where traditional infrastructure is slowest and most expensive.
The combination of lower costs, faster settlement, 24/7 availability and increasing regulatory clarity is driving adoption among businesses that move money regularly across borders. As off-ramp infrastructure improves and regulatory frameworks mature across African markets, stablecoin settlement will likely capture an increasing share of cross-border B2B payment volume.
For businesses evaluating stablecoin settlement, the key question is not whether to adopt it, but how to implement it in a way that is compliant, operationally sound and integrated with existing treasury processes.
