Payments in South Korea: What Global Businesses Need to Know

South Korea is built for digital payments. Near-universal banking access, widespread mobile wallets and a highly connected economy have made fast, convenient transactions an everyday expectation.

Cross-border payments face a complex environment.

Currency restrictions, local banking requirements and compliance processes make reaching South Korean recipients more complex. At the same time, South Korea’s banks and payment companies are already testing stablecoins and blockchain-based settlement, signalling where the market could head next.

This article looks at how payments work in South Korea, where global businesses can encounter friction, and what the country’s changing payment environment means for PSPs, MTOs, marketplaces and international businesses.

A digitally mature economy with high payment expectations

South Korea combines a large economy with near-universal access to digital financial services. GDP reached USD 1.93 trillion in 2025, while its population of 51.6 million has an internet penetration rate of 97.9%.

That digital maturity extends directly into financial services:

• 96.9% of people aged 15 and over have a bank account.
• 27.8 million people use mobile money services.
• South Korea is one of Asia’s largest e-commerce markets.

South Korea’s digital maturity also extends to how its payment systems connect beyond the domestic market. Payment interoperability describes how effectively different payment systems, providers and networks can work together, both locally and across borders. In Thunes’ Interoperability Index, South Korea ranks 13th globally, placing it among the stronger-performing markets for payment connectivity.

Yet a relatively high ranking doesn’t remove the complexity of moving money across borders. For international businesses, accessing South Korea still means working across local banking requirements, foreign exchange, compliance processes and established payment rails. 

That matters in a market where consumers and businesses are already accustomed to money moving quickly through digital channels. South Korea is primed for cross-border payments that can match the speed and convenience of domestic experiences, putting pressure on international payment providers to keep pace.

The local payment landscape in South Korea

South Korea’s high level of digital adoption is reflected in the range of payment methods people use.

Bank payouts remain the backbone for inbound flows

With 97% bank account ownership, South Korea has the banking coverage needed to receive funds directly into accounts. These inbound flows span several important use cases, including remittances, disbursements to freelancers and marketplace sellers and B2C, B2B and C2B commercial payments.

This shows that the ability to access local bank accounts is an important part of serving the South Korean market. 

Domestic payment experiences have already set a high bar for speed and convenience. Cross-border payout infrastructure needs to meet those expectations while working within South Korea’s local banking and regulatory requirements.

The role of mobile wallets in everyday payments

Mobile wallets are embedded into daily life in South Korea. Linked with bank accounts, these are supported by large technology companies that already play a significant role in how consumers shop, communicate and manage their finances.

South Korea’s mobile payments market reached $44.4 billion in 2025, forecast to grow to $48.3 billion in 2026, and there are several major players:
 

• KakaoPay, with around 36-40 million users, leads the way, processing KRW 167.3 trillion in payments in Q4 2024.
• Naver Pay, which has approximately 30 million users, surpassed KRW 25 trillion in quarterly payments for the first time in the second quarter of 2025.
• Toss reaches over 30 million users and is popular with the 20-30s demographic.
• Payco, a digital wallet with 12 million registered users, is used for one-time KRW purchases.

Their reach extends across e-commerce and physical retail, with payment services increasingly incorporated into broader apps and digital services. For consumers, mobile payments are part of an established payment experience rather than an emerging alternative.

Cards remain extremely important

Cards also retain a major role in South Korean payments. The country has approximately 6.7 cards per person, and cards account for around 70% of payments.

High card ownership means businesses serving South Korean consumers operate in a market where both card and mobile payment options are firmly established. This mix has contributed to expectations for convenient digital transactions across both online and offline commerce.

Where global businesses hit friction

South Korea’s domestic payment market is highly developed, but cross-border payments introduce a different set of operational requirements. 

The won adds complexity to cross-border settlement

The South Korean won remains much less widely used for international settlement than major currencies such as the US dollar. In 2025, KRW accounted for 3.4% of South Korean export settlements and 6.6% of import settlements, while the US dollar represented the large majority of both.

For payment providers, this can make cross-border flows into South Korea more operationally demanding. Funds may need to be converted into KRW, liquidity has to be managed across currencies, and settlement arrangements must work within South Korea’s foreign exchange rules.

The market is changing, though. The Bank of Korea is working to expand the international use of the won and plans to pilot a 24-hour offshore KRW settlement system by the end of 2026. Until those changes are established, global payment providers still need infrastructure that can handle KRW FX and settlement requirements. 

Domestic payment sophistication doesn’t remove cross-border complexity

South Korea has extensive local banking and payment capabilities, but accessing them from overseas can involve multiple institutions and processes.

A cross-border payment may need to pass through FX conversion, correspondent banking relationships, local clearing systems and compliance checks before reaching the beneficiary. Supporting multiple banks directly can also require separate commercial and technical relationships.

Compliance adds another layer. South Korean financial institutions are subject to customer due diligence requirements under the Financial Transaction Reports Act and Real Name Financial Transactions Act. Financial institutions must identify and verify customer information, including the real name of individuals and registered names of businesses.

For inbound payments, accurate beneficiary information matters. Account validation and beneficiary lookup can help identify mismatches before a payment is sent, reducing the risk of failed transactions and manual intervention.

Cross-border experiences have to keep pace with domestic expectations

Consumers in South Korea are already accustomed to digital payment experiences, and those expectations don’t disappear when money comes from overseas. 

A freelancer receiving payment from an international platform, a marketplace seller waiting for a disbursement, or a family receiving a remittance still expects funds to arrive quickly and conveniently.

The challenge for international providers is delivering that experience across a payment flow that may involve more FX, compliance and settlement steps than a domestic transaction. As South Korea’s local payment market continues to set a high standard, the gap between domestic and cross-border payment experiences is becoming increasingly apparent.

South Korea is preparing for the next generation of payments

Alongside its established banking and payment systems, South Korea is becoming an important testing ground for new forms of digital settlement, such as blockchain, tokenised deposits and stablecoins.

Stablecoins are a particular focus. Policymakers and financial institutions are discussing the development of a regulated market for won-denominated stablecoins, partly in response to the growing use of US dollar-backed stablecoins by Korean consumers and businesses. The Bank of Korea has also been examining how won-denominated stablecoins could coexist with central bank digital currency and tokenised deposits.

Financial institutions are already putting some of these ideas into payment trials:

• KB Financial Group has tested blockchain-based payments and cross-border remittances, while KB Kookmin Bank is also introducing blockchain-based trade payments using JPMorgan’s Kinexys network.
• Hana Financial Group is participating in stablecoin remittance testing, while Hana Card has trialled USDC payments for foreign visitors.
• Shinhan Card has worked with the Solana Foundation on stablecoin payment infrastructure.
• KakaoPay and Naver Pay are examining how stablecoins could fit within payment services that already reach millions of Korean consumers.

While these developments remain at different stages of commercial and regulatory maturity, they show where parts of the market are heading. Blockchain-based settlement is being examined by established financial institutions for practical payment, remittance and settlement use cases, rather than solely through the lens of retail crypto trading.

For global payment providers, this will add another dimension to South Korea’s payment market. 

How Thunes connects to payments in South Korea

Through a single API connection to its Direct Global Network, Thunes gives Members access to South Korean banks, supporting KRW payouts across C2C, B2C, B2B and C2B flows. Payouts can be made in real time.

Account validation and beneficiary lookup help Members verify recipient details before funds are sent, reducing the risk of payment failures caused by incorrect beneficiary information.

Behind the payment itself, Thunes’ wider infrastructure helps Members manage the requirements that come with international flows:

• SmartX Treasury System supports FX and liquidity management across currencies and markets, helping Members manage the treasury requirements involved in funding KRW payouts.
• Fortress Compliance Platform embeds compliance controls into every stage of payment flows, supporting the screening and monitoring required when moving money across borders.

This model gives businesses flexibility as South Korea’s payment market continues to develop. 

Through its Direct Global Network, Thunes gives Members access to South Korea’s existing real-time fiat payment rails today. As banks and payment companies test stablecoins, tokenised deposits and blockchain-based settlement, this model also gives Members a consistent way to access local payment capabilities as new settlement models develop, without rebuilding their cross-border payment infrastructure on a market-by-market basis.

What does this mean for payment strategy in South Korea?

South Korea combines high payment expectations with specific requirements for moving money across its borders. The implications vary depending on the type of payment provider:

• PSPs can access South Korean banks through a single connection, reducing the need to manage individual bank integrations.
• MTOs and remittance providers can offer real-time KRW payouts directly to recipients’ bank accounts, supported by account validation and beneficiary lookup.
• International businesses can support B2B, B2C and C2B payments while reducing the operational burden of managing local banking, FX and payment requirements independently.
• Marketplaces and digital platforms can pay freelancers, sellers and other recipients directly into local bank accounts, matching the digital payment expectations established across South Korea’s domestic market.

Access South Korea through the Direct Global Network

South Korea already has many of the characteristics of a highly developed digital payment market: near-universal banking access, widespread mobile payments and consumers accustomed to fast digital transactions.

The opportunity for global businesses is to bring cross-border payments closer to that domestic experience. At the same time, developments in stablecoins, tokenised deposits and blockchain settlement show that the country’s payment systems will continue to change.
