South Korea's Game-Changing Loan Switching Service Now Open to Small Business Owners

Starting March 18, 2026, South Korea's individual business owners can now refinance their credit loans through smartphones — a landmark expansion of the country's online loan switching infrastructure. Previously available only to individual borrowers, the service now extends to self-employed entrepreneurs and small business owners, opening the door to significant interest savings. According to the Financial Services Commission (FSC), last year's personal loan switching users — approximately 420,000 people — saved an average of 1.69 million won per person annually, with an average interest rate reduction of 1.44 percentage points. The regulator projects that over 1 trillion won in business loans will migrate to more favorable products through this new service.

For small business owners struggling under high interest rates amid a challenging economic environment, this service represents a tangible opportunity to reduce financial costs without the hassle of visiting bank branches in person.

How the Service Works: Platforms, Banks, and Eligibility

The business loan switching service is accessible through five major loan comparison platforms — Naver Pay, Kakao Pay, Toss, Banksalad, and Kakao Bank — as well as the proprietary apps of 13 participating banks. Any registered business owner aged 19 or older can apply, with working capital credit loans of up to 1 billion won eligible for switching.

The 13 banks available at launch include Shinhan, KB Kookmin, Hana, Woori, NH Nonghyup, iM Bank, IBK Industrial, Jeonbuk, Gwangju, Busan, Kakao Bank, K Bank, and Toss Bank. Three additional banks will join on a staggered timeline: Jeju Bank (end of March), Gyeongnam Bank (end of April), and Sh Suhyup Bank (by year-end). Existing loans from a total of 18 banks — including SC First Bank and Citibank — can be queried for comparison.

The service operates on business days from 9:00 AM to 4:00 PM, with plans to extend hours to 10:00 PM once the system stabilizes. Elderly users and others who may find digital platforms challenging can still visit bank branches in person to access the switching service.

Key Analysis: More Flexible Than Personal Loan Switching

What makes the business loan switching service particularly noteworthy is its significantly more flexible terms compared to the existing personal loan switching framework. Three critical restrictions have been eliminated.

First, there is no waiting period. While personal mortgage refinancing required borrowers to wait six months after taking out a loan, business owners can switch immediately regardless of when the original loan was issued. Second, loan amount increases are permitted. Unlike personal mortgage switching, which only allowed refinancing within the existing balance, business owners can refinance for a larger amount — effectively combining debt consolidation with additional capital access. Third, there are no maturity restrictions, unlike the jeonse (housing deposit) loan switching service which imposed a half-contract-period limitation.

However, not all business loans qualify. Construction interim loans, B2B transaction-related loans, and real estate rental business loans are excluded from the service. Additionally, low-interest policy finance products that already carry preferential rates are ineligible, a measure designed to prevent adverse selection.

Bank Competition Heats Up: Preferential Rates and Special Incentives

The service launch has triggered intense competition among major banks to attract business borrowers. KB Kookmin Bank is offering all customers who switch through non-face-to-face channels a dedicated preferential rate of up to 0.3 percentage points, along with first-month interest support of up to 100,000 won. KB Kookmin's maximum loan limits are set at 300 million won through branches and 200 million won through digital channels.

Shinhan Bank is targeting working capital credit loans of up to 100 million won, emphasizing its commitment to reducing borrowers' financial burden. Hana Bank has taken a differentiated approach by launching a new dedicated product called "Hana The Soho Credit Loan" specifically for this service, while also offering free cyber financial crime compensation insurance from Hana Insurance to all switching customers.

This competitive dynamic is expected to push actual interest rate savings beyond the historical average, as banks vie aggressively for market share during the critical early adoption phase.

Strategies to Maximize Your Savings

To get the most out of this service, business owners should adopt a multi-platform comparison approach. Since each of the five platforms — Naver Pay, Kakao Pay, Toss, Banksalad, and Kakao Bank — may feature different partner banks and loan products, checking all five platforms ensures you find the most competitive rate available.

Beyond headline interest rates, pay close attention to bank-specific switching incentives. KB Kookmin's 0.3 percentage point preferential rate and Hana Bank's free insurance coverage represent value that simple rate comparisons might miss. Early movers may also benefit from more aggressive launch-period promotions, making the initial weeks of the service particularly advantageous for switching.

The ability to increase loan amounts during refinancing presents an opportunity to simultaneously reduce interest costs and secure additional working capital. However, borrowers should exercise caution and carefully assess their repayment capacity before opting for a larger loan, as overextension could create new financial pressures.

Historical Context: The Evolution of Korea's Loan Switching Infrastructure

South Korea's online loan switching ecosystem has evolved rapidly since its inception. The journey began in May 2023 with personal credit loans, when 105,696 borrowers transferred a total of 2.38 trillion won, achieving an average rate reduction of 1.6 percentage points and per-person annual savings of 540,000 won. The service expanded to apartment mortgage loans in January 2024, followed by jeonse deposit loans later that same month.

By the end of 2025, the cumulative impact was substantial: 22.8 trillion won in total loan transfers across approximately 420,000 users, with average per-person savings growing to 1.69 million won annually. The dramatic increase in per-person savings — from 540,000 won in the first year to 1.69 million won — reflects both the maturation of the platform and intensified competition among financial institutions.

The expansion to business loans in March 2026 marks the fourth major phase of this initiative, with the FSC signaling that facility loans, guaranteed loans, and collateralized loans for business owners may follow in future phases.

Broader Impact on Small Business Finance

This service represents more than just a new refinancing channel — it signals a structural transformation in South Korea's small business lending market. Historically, small business owners faced significant friction when attempting to change their banking relationships, with branch visits and complex documentation creating de facto barriers to competition. By enabling smartphone-based rate comparison and loan transfers, the service is expected to catalyze genuine price competition among banks for business lending.

The timing is significant. The Korean government has allocated a record 5.4 trillion won in small business-related budget for 2026, and existing policy lending programs for small merchants offer rates around 2.96% (as of January 2026). The new switching service complements these policy measures by introducing market-driven competition alongside government subsidies, creating a dual-track approach to reducing small business financing costs.

The broader implications extend to Korea's fintech ecosystem as well. Platforms like Toss, Kakao Pay, and Naver Pay are increasingly becoming central hubs for financial decision-making, and their role as loan comparison intermediaries further cements their position in the country's financial infrastructure.

Conclusion: A Pivotal Moment for Small Business Borrowers

The launch of the business loan switching service marks a pivotal moment for South Korea's 6+ million small business owners. With five major fintech platforms, 13 banks competing from day one, flexible terms including immediate switching eligibility and loan amount increases, and historical data showing average savings of 1.69 million won per person, the value proposition is compelling. Business owners currently holding credit loans should take immediate action — open Toss, Kakao Pay, or Naver Pay, compare available rates, and determine whether switching can reduce their interest burden. With banks offering their most competitive rates and incentives during the launch period, the optimal window for switching is right now.
