Bank of Korea Weighs November Rate Hike as Stock Market Plunge Complicates the Call
Direct answer
South Korea’s central bank has a difficult decision to make on November 26. Growth came in much stronger than expected and inflation is still above target, which points to another interest rate hike. But the country’s stock market has just suffered a sharp two day fall, which makes raising rates riskier. The Bank of Korea held its base rate at 3.00% in October, and most economists still expect a quarter point rise to 3.25% this month, though the market turmoil has made that call less certain.
What happened
The Bank of Korea’s Monetary Policy Board holds its final meeting of the year on November 26, when it will also release updated growth and inflation forecasts. At its last meeting on October 22, the board voted unanimously to hold the base rate at 3.00%, pausing after quarter point hikes in July and August. Governor Shin Hyun-song signalled then that the tightening cycle was not over, and a Reuters poll of economists found the median forecast was a hike to 3.25% in November.
The case for a hike has only grown stronger since then. South Korea’s economy grew 1.0% in the third quarter from the previous quarter, far above the Bank of Korea’s own forecast of 0.3%. Both headline and core consumer prices rose 2.8% in October, still clearly above the bank’s 2% inflation target. Deputy Governor Lee Ji-ho said on November 3 that inflation in November would stay in the upper 2% range, and the bank expects next year’s inflation outlook to be revised higher. Aju Press reported his remarks on November 3.
Then the stock market fell sharply. The KOSPI index peaked at 6,012.44 on October 28 and then dropped 11.0% across the two sessions of November 5 and 6, breaking below 5,000 during trading on November 6 for the first time in nine months. The fall was driven by worries that US rules on data centre investment could slow demand for the computer chips that power South Korea’s export boom.
That drop has split opinion. Bond market traders told Yonhap Infomax on November 6 that a hike may become impossible if the KOSPI falls toward 4,000, and some now see the peak rate at 3.25% rather than 3.50%. Citi, by contrast, kept its forecast of quarter point hikes in November and February, saying the market fall was not enough to change the rate path. The minutes of the October 22 meeting, due on November 10, should show how the board weighed growth and inflation against market volatility.
Why it matters for beginners
A central bank raises interest rates to cool inflation, and it cuts them to support growth. When growth is strong and prices are rising faster than the 2% target, a hike is the normal response. But higher rates also make borrowing more expensive for households and companies, and they can push share prices down, because future company profits look less valuable when rates are higher.
South Korea shows both sides of that trade off in one story. Inflation is still running at 2.8%, and growth beat forecasts, so the bank has reason to act. At the same time, the KOSPI has already fallen sharply, and a rate rise could add to the pressure on households and investors. For beginners, the lesson is that central bank decisions are rarely simple, and the same strong economy that justifies a hike can make the hike harder to deliver.
What to watch next
The minutes of the October 22 meeting arrive on November 10 and will show how board members balanced the case for a hike against worries about the market. Then the decision itself comes on November 26, along with fresh growth and inflation forecasts. Watch whether the KOSPI steadies or falls further before then, because a deeper slide would strengthen the case for waiting. If the bank does raise rates to 3.25%, the next question is whether it signals more hikes into 2027 or a pause to see how the economy responds.
FAQ
What is the Bank of Korea’s base rate?
It is the benchmark interest rate set by South Korea’s central bank. It guides borrowing costs across the economy, from mortgages to business loans. The rate is currently 3.00% after hikes in July and August 2026.
Why would the bank raise rates when the stock market is falling?
Because inflation is still above its 2% target and growth is stronger than expected. The bank’s job is to bring inflation back to target, and it has said policy will stay restrictive until that happens. A falling stock market is a concern, but it is not the bank’s main target.
What does a rate hike mean for ordinary people in South Korea?
Borrowing gets more expensive. Mortgage payments and loan costs rise, which can cool spending and house prices. Savers, on the other hand, earn more interest on deposits. For investors, higher rates can weigh on share prices, especially for fast growing companies.
When will we know the decision?
The Monetary Policy Board meets on November 26, 2026, its last meeting of the year. It will announce the decision that day, together with updated forecasts for growth and inflation.
