Cross-Border KRW Remittance Corridors to Asia and the Middle East: Reference Rates vs Bank Spreads
Understanding the distinction between institutional mid-market reference rates (ECB / Korea Eximbank Deal Base Rate) and retail bank cash/telegraphic transfer spreads across 16 foreign currencies used by residents in South Korea.
📊 Key Verified Figures & Units
Under South Korea’s Foreign Exchange Transactions Act administered by the Ministry of Economy and Finance (MOEF), exchange rates displayed by public statistical portals represent the Deal Base Rate (매매기준율) or Mid-Market Reference Rate—the midpoint between interbank buy and sell quotes.
When individuals exchange physical banknotes or send international remittances in USD, EUR, JPY, CNY, EGP, SAR, AED, VND, PHP, NPR, LKR, UZS, or PKR, commercial banks and MOEF-licensed small-sum overseas remittance providers (소액해외송금업자) apply a currency-specific spread and transfer fee.
Comparing the Telegraphic Transfer Selling Rate (TTS / 송금 보낼 때) against the Mid-Market Reference Rate allows foreign workers and students in Korea to verify exact conversion costs before initiating an international transfer.
