Korean Stock Plunge Triggers Circuit Breaker, Safe Haven Sentiment Rattles Asia-Pacific Markets

BlockBeats News, March 3rd. Influenced by the escalation of the Middle East situation and expectations of soaring energy costs, global markets quickly warmed up to risk aversion. The South Korean benchmark index KOSPI plummeted by 5.6% at one point during Tuesday's trading, marking the largest single-day drop since November last year and triggering a circuit breaker mechanism, temporarily halting algorithmic trading. The South Korean won fell by 1.9% against the US dollar, marking the biggest single-day drop since May last year.

Pressure spread across the Asia-Pacific markets. The Nikkei 225 fell by about 2.5% during trading, and the MSCI Asia Pacific Index recorded its largest two-day decline since April last year. US and European stock index futures also declined, with the market expecting increased volatility.

South Korean tech giants led the decline, with Samsung Electronics and SK Hynix both falling by over 6%. The aviation and automotive sectors weakened, while defense stocks showed strength, with Hanwha Aerospace and LIG Nex1 both rising by over 25%. Energy stocks showed relative resilience to the downturn.

Analysts point out that if the conflict involving Iran evolves into a long-term confrontation, oil prices may remain high, exacerbating inflationary pressures and disrupting the monetary policy path. KOSPI has still risen by over 40% year-to-date, led by semiconductor stocks amid the AI boom, with current valuations being sensitive to changes in interest rates and liquidity expectations.

In terms of fund flows, foreign investors have been selling massively, with a net selling volume exceeding 40 trillion Korean won (about $27 billion), while retail investors are buying on dips. Some institutions believe that if the conflict escalation remains under control, the pullback may provide a mid-term positioning opportunity. However, there are also warnings that if oil prices continue to rise and impact capital expenditure and hiring decisions, the downside market risk may accelerate.
