# South Korea rate policy and rising household debt > Live situation record from CLSTR: https://clstr.news/situations/south-korea-rate-policy-and-ai-fueled-growth > Updated: 2026-09-17T00:19:03.000Z. Sources: 44. Developments: 9. On August 27, 2026, the Bank of Korea (BOK) Monetary Policy Board implemented a second consecutive increase, raising the benchmark interest rate by 0.25 percentage points from 2.75% to 3.00%. This “back-to-back” hike is the first of its kind in approximately three years and seven months, marking the first time the rate has entered the 3% range since February 2025. The decision was driven by stronger-than-expected economic growth and persistent inflation, with the BOK upgrading its 2026 GDP growth forecast to 3.3% due to robust semiconductor exports and AI-driven investment. While commercial banks have intensified competition for deposits, concerns regarding household debt persist. Data from the Financial Supervisory Service shows that bank overdraft (minus account) loan balances surged to 69.7 trillion won by late July, a 9.6% increase from the end of 2025. Borrowing costs have risen significantly, with average overdraft rates climbing to 5.64% in July. By mid-September 2026, a rare inversion in the banking sector emerged, where one-year fixed deposit rates in the mid-3% range exceeded two-year rates, which remained between 2.7% and 3%. This phenomenon is attributed to regulations limiting the total volume of household loans, which reduces banks' need to secure long-term funds. Furthermore, rising corporate loan delinquencies have made banks hesitant to offer higher interest for long-term capital. This shift has coincided with a ‘reverse money move’, as funds migrate from the stock market into short-term deposits in anticipation of further interest rate hikes. On September 17, 2026, South Korean financial authorities, including Finance Minister Koo Yun-cheol and BOK Governor Shin Hyun-song, met to assess market stability following the U.S. Federal Reserve’s decision to raise its benchmark rate to a 3.75-4.00% range. ## Claims - This was the second consecutive rate hike by the central bank.
