Yesterday's Recap

Korean markets tumbled on March 30 amid escalating Iran war concerns, with the KOSPI closing at 5,277.30 after a 2.97% decline, driven by tech sector weakness over potential chip supply disruptions. KOSDAQ dropped 3.02% to 1,107.05, led by losses in Samsung Electronics, down 3.80% to 169,600.00, and SK Hynix, off 5.44% to 825,500.00, as reports warned of global microchip production risks. USD/KRW eased 0.08% to 1,505.79, limiting won weakness despite risk-off mood.

Short-term rates climbed 0.40% to 2.54%, and long-term rates surged 3.64% to 3.61%, reflecting bets on persistent high rates due to oil-driven inflation. No key data releases, but sentiment soured on South Korea's proposed $17 billion budget to mitigate energy costs from the conflict, with 72% of crude imports from the Middle East at risk. Export-heavy sectors faced pressure from supply chain threats.

The Day Ahead

No major economic releases are slated for March 31, shifting focus to global fallout from the Iran war, including oil supply and chip disruptions. Markets may react to updates on the $17 billion energy budget or proposed driving restrictions, impacting energy and auto sectors. Semiconductor stocks like Samsung and SK Hynix could stay volatile amid supply chain warnings.

The won and broader equities may fluctuate without domestic drivers. Eyes on Bank of Korea responses, including views from nominated governor Shin Hyun Song on navigating external pressures. Monitor for any fiscal or geopolitical announcements.

Other Economic Notes

South Korea's export-reliant economy is under strain from the Iran conflict, with 72% of crude oil sourced from the Middle East facing potential disruptions, leading to a $17 billion supplementary budget proposal. The semiconductor sector, vital for growth, risks a global crunch due to Gulf supply chain vulnerabilities, such as helium from Qatar. Rising AI demand and high-end packaging markets, projected to reach USD 134.90 billion by 2035, could intensify shortages.

Animal protein ingredients market growth to USD 15,566.54 million by 2032 highlights broader nutrition trends, but energy costs may weigh on related industries.

Global Macro News

The Iran war is fueling a global oil shortage, prompting South Korea to consider driving curbs for the first time in 35 years to preserve fuel amid heavy Middle East import reliance. This threatens a microchip shortage, jeopardizing Korea's semiconductor exports reliant on Gulf materials and Strait of Hormuz routes. Brent crude fell 8.44% to 103.26, yet volatility stokes inflation, compelling Asian central banks like the BoK to reassess rate cuts amid outflow risks.

AI's high energy needs exacerbate strains, with data centers demanding more power, pressuring Korea's tech firms. Gold climbed 3.82% to 4,698.70 as a haven, Bitcoin rose 2.05% to 68,061.27, but these provide scant relief. Geopolitical moves, including U.S.

actions in Iran, risk global trade chokepoints, affecting Korea's shipbuilding. Korean AI startup Rebellions raised $400 million for global expansion, offering long-term potential despite near-term hurdles.

BoK Watch

The Bank of Korea's base rate remains at 2.54% since its February 2026 adjustment, with officials stressing caution amid Iran conflict shocks. President Lee Jae Myung nominated BIS official Shin Hyun Song as new governor, emphasizing global expertise for inflation and stability challenges from fuel costs. BoK communications underline data-dependent policy, but the crisis heightens cut risks due to imported inflation and outflows.

Deputy governors have focused on energy price monitoring, potentially delaying easing. Recent MPC minutes prioritize financial stability and won support over aggressive moves. This suggests sustained higher rates, weighing on bonds and export stocks amid tensions.
