A $220 Billion Market Gets Its Digital Disruption Moment

On March 18, 2026, South Korea's fintech landscape shifted dramatically. Three of the country's most prominent financial platforms — Toss, KakaoPay, and Banksalad — simultaneously launched business loan refinancing services for individual entrepreneurs and small business owners. Built on the government-backed Loan Transfer System developed by the Financial Services Commission (FSC) and the Korea Financial Telecommunications & Clearings Institute, this coordinated launch marks the opening salvo in what promises to be an intense battle for Korea's approximately 300 trillion won ($220 billion) self-employed lending market.

Previously, loan refinancing through mobile platforms was limited to salaried workers with personal credit loans. Now, small business owners and self-employed individuals can compare and switch to lower-rate products — starting from as low as 3.76% APR — entirely through their smartphones. For the millions of Korean entrepreneurs paying elevated interest rates on business credit loans, this represents a potentially transformative opportunity to cut annual interest costs by hundreds of thousands of won.

How the Business Loan Refinancing System Works

Korea's business loan refinancing (대환대출, or "loan switching") infrastructure is a world-first initiative led by the FSC. The system enables borrowers to transfer existing business credit loans to new, lower-rate products without visiting bank branches — a process that previously required extensive paperwork and in-person appointments. The entire process can now be completed in approximately five minutes via mobile app.

The service launched across 5 fintech comparison platforms (including Naver Pay, KakaoPay, Toss, and Banksalad) and 13 bank apps (KB Kookmin, Shinhan, Hana, Woori, NH Nonghyup, IBK, K Bank, and others). Eligible loans include unsecured business credit loans from commercial banks and savings banks, while policy-backed guaranteed loans are currently excluded.

A significant regulatory enhancement accompanied the launch: starting March 18, 2026, volume-increasing refinancing is now permitted for operating fund loans up to 1 billion won ($730,000), meaning borrowers can not only switch to a lower rate but also increase their loan amount in the process. Applications are processed in real-time during business hours (9 AM to 4 PM on business days), with required documentation including business registration certificates, lease agreements, and two years of tax documentation.

Platform Comparison: Three Distinct Approaches

Toss — Speed and Simplicity

Toss, Korea's leading fintech super-app, branded its offering "사장님 신용대출 갈아타기" (Boss's Credit Loan Refinancing). True to its reputation for intuitive UX, Toss enables users to query all existing business credit loans in a single action, instantly check refinancing eligibility, and compare conditions across 6 participating financial institutions. When conditions are met, the entire loan execution process is completed within the app without additional documentation.

Through Toss Bank (its banking subsidiary), the platform offers refinancing products for licensed professionals at rates as low as 3.76% to 4.43% APR with maximum limits of 500 million won ($365,000). This positions Toss Bank as the market leader on headline rates, though eligibility for the lowest rates is restricted to professional-category borrowers.

KakaoPay — Scale Through Data

KakaoPay's competitive advantage lies in its extraordinary reach: approximately 22 million MyData subscribers provide the platform with an unparalleled dataset for personalized financial recommendations. Its "개인사업자대출 갈아타기" (Individual Business Loan Refinancing) service requires only a resident registration number input, after which the platform automatically aggregates scattered business loan information and recommends eligible products based on business location and verified income data.

Having already built significant expertise through existing refinancing services for personal credit loans, mortgage loans, and lease deposit loans, KakaoPay's extension into business lending leverages proven infrastructure and user trust. The platform's emphasis on non-face-to-face convenience makes it particularly appealing to time-pressed entrepreneurs.

Banksalad — AI-Powered Inclusive Finance

Banksalad, Korea's premier MyData specialist, differentiates itself through an AI-based Small Business Credit Scoring System (CSS) that goes beyond traditional credit evaluation. While conventional systems rely primarily on credit bureau scores, Banksalad's model incorporates sales flow patterns, business tenure, tax payment history, and other non-financial data points to identify creditworthy borrowers among mid-to-low credit entrepreneurs — a demographic traditionally underserved by mainstream banks.

With 9 participating financial institutions — the most among the three platforms — Banksalad offers the widest comparison range. The platform's track record in personal loan refinancing includes documented interest rate reductions of up to 13 percentage points, demonstrating the potential magnitude of savings available through comprehensive comparison.

The Numbers: Quantifying the Impact

The financial case for business loan refinancing is compelling. Data from existing personal loan refinancing services shows that approximately 32,000 borrowers have refinanced loans totaling 1.7 trillion won, achieving average rate reductions of 1.58 percentage points — equivalent to annual interest savings of approximately 840,000 won ($615) per borrower.

For business loan refinancing, the FSC projects even stronger results. Regulators anticipate average rate reductions of 1.45 percentage points, translating to annual interest savings of approximately 1.77 million won ($1,300) per borrower. If the service expands from bank-issued credit loans to include second-tier financial institutions and secured products, aggregate annual financial cost savings could reach 65 billion won ($47.5 million).

Market trends already point in a favorable direction. Average interest rates on first-tier bank business loans intermediated through the Finda platform dropped from 6.56% in December 2024 to 5.33% by February 2025 — a decline of 1.23 percentage points in just two months. With three major fintech platforms now competing directly for refinancing volume, downward pressure on rates is expected to intensify significantly.

Strategies for Maximizing Savings

Business owners seeking to optimize their refinancing outcomes should adopt a multi-pronged approach. First, comparing across multiple platforms simultaneously is essential, as each platform partners with different financial institutions and may surface different rate offers. Toss works with 6 lenders while Banksalad connects with 9, meaning a comprehensive comparison requires checking at least two platforms.

Second, prioritizing second-tier financial conversions delivers the largest absolute savings. Borrowers currently holding loans from savings banks or capital companies at rates of 7% or higher can realize dramatic interest reductions by switching to commercial bank products. The government-backed SME refinancing program offers a fixed 4.5% rate for borrowers with NCB credit scores of 919 or below who are currently paying 7% or more.

Third, leveraging MyData connectivity can improve credit assessment outcomes, particularly on Banksalad's AI-driven platform. By ensuring that sales data, tax records, and other business performance indicators are fully synced, borrowers can present a more comprehensive picture of their creditworthiness. This is especially valuable for mid-to-low credit entrepreneurs whose traditional credit scores may not reflect their actual business health.

Finally, borrowers should always verify early repayment penalties before switching. Some financial institutions impose prepayment fees within the first three years of loan origination, and the net benefit of refinancing should be calculated after accounting for these costs.

Competitive Landscape and Market Outlook

The simultaneous launch by three major platforms signals the beginning of an intensely competitive phase in Korea's fintech lending ecosystem. The five major banks held combined self-employed loan balances of 324.8 trillion won as of February 2026, representing a massive addressable market that is growing month over month.

Each platform has staked out a distinct competitive position: Toss competes on speed and UX simplicity, KakaoPay leverages its 22 million MyData user base for personalized recommendations, and Banksalad focuses on AI credit scoring and inclusive finance for underserved borrowers. Additionally, Naver Pay and Finda have entered the market, ensuring that competitive pressure remains high across the ecosystem.

Looking ahead, the FSC plans to expand the refinancing infrastructure to include secured business loans in the second half of 2026. The government has also allocated 12.1 billion won for fintech industry development, including financial testbed programs and international expansion support. As the MyData 2.0 strategy advances and business-specific credit evaluation systems mature, the fintech-driven democratization of small business lending in Korea appears set to accelerate further.

Key Takeaways

The coordinated launch of business loan refinancing services by Toss, KakaoPay, and Banksalad represents a watershed moment for Korea's 300 trillion won self-employed lending market. With minimum rates starting at 3.76% APR, projected average rate reductions of 1.45 percentage points, and potential annual savings of 1.77 million won per borrower, the financial incentives for small business owners to refinance are substantial. The combination of government infrastructure, fintech innovation, and AI-powered credit assessment is creating a more competitive, transparent, and accessible lending environment — one that has the potential to meaningfully reduce the financial burden on Korea's 6.9 million self-employed workers. For business owners currently paying elevated interest rates, the message is clear: now is the time to compare, switch, and save.
