South Korea’s rise in household debt raises questions over financial stability South Korea’s rise in household debt raises questions over financial stability · Retail Banker International Global Data Mon, June 29, 2026 at 5:36 PM GMT+7 3 min read South Korea witnessed a sharp increase in household borrowing in May 2026, with loans rising from KRW2.1tn ($1.4 bn) to KRW6.9tn ($4.5bn), marking the fastest monthly increase since August 2024. Lower borrowing costs and a wealth effect driven by the stock market rally have boosted consumer confidence and encouraged investment activity. However, the rapid pace of borrowing raises concerns over the quality and sustainability of credit growth.The strong performance of South Korean equities, particularly AI- and semiconductors-related stocks, has attracted significant retail investor participation. Driven by fear of missing out (FOMO) on potential returns, many individuals appear to have borrowed funds to invest in the stock market, mainly leveraged ETFs. According to the Financial Supervisory Service, much of the increase in lending came from personal credit lines and overdraft accounts, while investor deposits at securities firms reached a 12-month high. Although rising equity markets have generated wealth for some investors, leveraged exposure to highly volatile assets leaves households vulnerable to sharp market corrections.

The sustainability of this borrowing is particularly concerning given South Korea's already elevated household debt burden. With a debt-to-income ratio of 174%, many households are under considerable financial pressure, and additional borrowing could further weaken balance sheets. Moreover, a significant proportion of recent loans has been taken by individuals in their 20s and 30s, whose repayment capacity is already stretched. Their debt service ratios of approximately 40–50% imply nearly half of disposable income is allocated to debt repayments, leaving limited room for consumption and savings.

GlobalData's Global Lending Analytics 2025 cites 44% of borrowers in South Korea missed or have fallen behind on their loan payments in the past six months.
