Stablecoin

Definition

A stablecoin is a cryptocurrency pegged to a fiat currency — typically USD — designed to hold price stability, used increasingly for cross-border B2B settlement.

A stablecoin is a cryptocurrency designed to maintain a stable value by pegging to a reference asset — typically the US dollar. USDC (Circle) and USDT (Tether) are the two dominant dollar-pegged stablecoins, with combined market caps exceeding $150B. In B2B payments, stablecoins are used as settlement instruments for cross-border corridors where correspondent banking is slow or expensive, with USDC preferred for enterprise use due to its fully-reserved, independently-attested structure.

Stablecoins bridge cryptocurrency infrastructure and fiat-denominated commerce. For payment operators, the relevant stablecoins are those pegged 1:1 to the US dollar — primarily USDC and USDT — which function as dollar-denominated instruments that settle on blockchain infrastructure rather than through correspondent banking.

USDC vs USDT

USDC (USD Coin) is issued by Circle (in partnership with Coinbase). Reserves are held in short-duration US Treasury instruments and cash at regulated US financial institutions. Circle publishes monthly attestations from a Big Four auditor. USDC is the enterprise default for regulated businesses due to its reserve transparency and regulatory standing under emerging US stablecoin legislation.

USDT (Tether) has a larger market cap and deeper liquidity, particularly in emerging markets where BNPL infrastructure was built on USDT rails. Tether’s reserve disclosures have historically been less transparent, making it difficult for regulated enterprises to hold USDT in corporate treasury without auditor complications. Tether has improved disclosures; the institutional trust gap persists.

B2B Settlement Use Cases

Stablecoins deliver meaningful advantages over SWIFT in specific corridors:

  • US → Mexico: USDC → SPEI via licensed off-ramp providers (e.g. Bitso). Total cost 2–3x cheaper than SWIFT wire on transactions above $10K.
  • UAE → South Asia (Pakistan, Philippines): Avoids US correspondent bank touchpoints that create AML hold risk. Settlement in minutes vs 1–5 day SWIFT uncertainty.
  • US → Argentina: USDT widely held as a USD substitute due to ARS inflation. B2B invoicing and treasury in USDT is commonplace.

Where Stablecoins Don’t Compete

  • US → EU/UK: SEPA and Faster Payments already work well. No meaningful advantage over existing fintech rails.
  • Transactions above $5M: Off-ramp liquidity for large single conversions is limited; SWIFT wires are better understood by treasury teams.
  • Markets with hostile or unclear stablecoin regulation: China, restrictive jurisdictions where the fiat off-ramp is unreliable.

Regulatory Trajectory

US GENIUS Act (2025), EU MiCA (2024–2025), UAE VARA, and UK FCA frameworks are all moving toward licensed stablecoin operation — providing legal clarity rather than prohibition. USDC already meets the reserve requirements these frameworks impose.
