 <li>The Bank of Korea raised its benchmark interest rate to 2.75%, citing inflation, stronger growth, and currency weakness despite retail buying.</li>

The Bank of Korea raised its benchmark interest rate for the first time in three and a half years, sending South Korean stocks into a broad selloff. <a href="https://x.com/Crypto_Briefing/status/2077617796570341873" rel="noopener noreferrer nofollow">According to Crypto Briefing</a>, the policy move coincided with renewed weakness in global semiconductor shares, pushing both the KOSPI and KOSDAQ low enough to trigger market safeguards. 
The benchmark KOSPI fell more than 6%, activating a sell-side circuit breaker designed to curb excessive market volatility. Meanwhile, the technology-heavy KOSDAQ also triggered protective measures after dropping more than 4%, highlighting widespread selling across the market. 
Semiconductor companies led the market downturn, with Samsung Electronics and SK Hynix recording significant losses as investors reacted to an overnight slump in U.S. chip stocks. Market participants grew more cautious over expectations that spending on artificial intelligence infrastructure could slow. 
Moreover, foreign and institutional investors maintained strong selling pressure throughout the session. Retail investors stepped in to buy lower-priced shares. However, their purchases were not enough to reverse the broader market decline.

According to the update, the <a href="https://36crypto.com/bank-of-korea-pushes-crypto-circuit-breakers-after-43b-bithumb-error/" rel="noopener noreferrer nofollow">Bank of Korea</a> increased its benchmark interest rate by 25 basis points to 2.75%, ending a pause that lasted three and a half years. 
The central bank cited stronger economic growth, persistent inflation, and weakness in the Korean won as key reasons behind the decision. Additionally, policymakers expect the economy to expand faster than previously forecast, supported by resilient semiconductor exports.

However, officials warned that inflationary pressures remain elevated despite improving economic conditions. Consequently, the central bank indicated that additional policy tightening could become necessary if inflation fails to ease. 
Governor Shin Hyun Song pointed to upcoming inflation and gross domestic product reports as the main indicators for future policy decisions. Market expectations also favor at least one additional rate increase before the end of the year if economic data remains strong.

Investors also monitored developments in the global semiconductor industry, which remains a key driver of South Korea’s economy. Weakness in U.S. chip stocks added another layer of uncertainty, weighing heavily on major Korean technology companies. 
Besides, higher borrowing costs have raised concerns about corporate financing conditions and investor appetite for growth stocks. Those factors combined to create one of the market’s weakest trading sessions in recent months. 
South Korean equities declined significantly as higher interest rates and weakness in the semiconductor sector weighed on investor confidence. While the central bank expects stronger economic growth, inflation concerns and uncertainty surrounding the chip sector remain key factors influencing market sentiment.
