International Market Correlation
U.S. tech weakness and FOMC rate hike concerns
The oil price spike following Middle East geopolitical tensions is fueling U.S. inflation concerns, leading to widespread fears that the Fed may adopt a more hawkish stance. This could lead to worsening earnings for Korea's semiconductor and IT exporters.
Surge in global oil prices and crude oil futures
WTI crude prices have surged due to the reignited Middle East tensions, worsening the global economic outlook. Increased burden from energy imports and rising manufacturing costs in Korea are major concerns.
Checkpoints for Tomorrow
- U.S. FOMC meeting results — Whether a rate hike is signaled is the key factor determining the direction of the Korean market.
- Developments in Middle East tensions — Monitoring for further oil price spikes or stabilization.
- Foreign supply/demand shift — Crucial to watch if the massive 3.3 trillion won net selling continues.
Investor Action Items
- Must confirm the direction of foreign and institutional supply/demand early in the session (potential for further sidecar triggers).
- Review earnings consensus and re-evaluate guidance for semiconductor-related firms.
- Monitor whether the 1,470–1,480 won range holds for the KRW/USD exchange rate.
