"USDT wins on volume; USDC wins on compliance. For enterprise B2B payments, the right choice depends entirely on the corridor and the counterparty." Artemis Research, 2025

USDT: The Volume Leader Across Emerging Markets

USDT controls 85% of global stablecoin payment volume. In corridors spanning Southeast Asia, Latin America, Eastern Europe, and Sub-Saharan Africa, USDT is the de facto dollar. Its dominance is explained by first-mover advantage, deep OTC liquidity, and the fact that in many emerging markets USDT functions as a practical savings vehicle against local currency depreciation. For B2B payments on the Singapore-China corridor, USDT on Tron is standard. For Turkey-Germany trade, USDT is often the only liquid option.

USDC: The Compliance-Grade Choice for Western B2B

USDC, issued by Circle, is the preferred stablecoin in markets where counterparties demand auditable, regulated infrastructure. Circle publishes monthly reserve attestations by Big Four accounting firms. USDC is the stablecoin of choice for US enterprises, European businesses operating under MiCA, and any corporate treasury that needs to demonstrate to auditors that its digital assets are held in verifiable, fully-backed instruments.

Corridor-by-Corridor Recommendation

USA → Europe: USDC. USA → Latin America: USDC preferred, USDT accepted. Singapore → China: USDT. Any corridor → Africa: USDT. Any corridor → India: USDC gaining share. The practical rule: if your counterparty is in a regulated Western market and your compliance team needs audit-grade reserves, use USDC. If you're paying into emerging markets where USDT has deeper OTC liquidity, USDT is typically more efficient. Truman supports both.
