Seoul

South Korea's capital; a global finance hub whose markets seize when The Gulf burns.

South Korea's F-1-D workation visa, made permanent on 30 June 2026, gives young foreigners a lower income bar only if they settle outside Seoul, Incheon and Gyeonggi Province, steering newcomers away from the capital region.

Background

Seoul is South Korea's capital and its main financial and corporate centre, home to national institutions, the stock market and the head offices of the country's largest technology companies.

National policy now tries to spread that weight. On 26 August 2026 the energy ministry and state utility KEPCO proposed eleven electricity pricing zones with lower industrial rates outside southern Seoul and southern Gyeonggi, to steer new chip plants and AI data centres away from the capital's congested grid. On 21 August the planning and budget ministry announced a Future Response Fund to ring-fence above-trend tax revenue from the chip and AI boom, which analysts put at 60 to 150 trillion won, with youth employment among its priorities.

South Korea's AI Basic Act took effect in January 2026 without pre-deployment safety checks, a lighter regime than other large jurisdictions apply. The capital's markets also carry outside shocks: the KOSPI fell 12% on 4 March 2026 during the Gulf crisis, its worst single-day fall.

Key Issues

Workation visa

Seoul sits outside the regional visa discount

South Korea made its F-1-D workation visa permanent on 30 June 2026, ending a pilot that had run since January 2024, and raised the maximum stay from two years to three. The lower bar, about US$36,963 or the country's per-Capita gross national income, now applies to under-35s from age 18 WHO base themselves beyond the capital, Incheon and Gyeonggi Province, rather than the pilot's flat bar of twice that figure.

A nomad WHO settles in the capital region gains no such discount. Justice minister Jung Sung-ho framed the scheme in June around foreigners voluntarily putting down roots, and the design places those roots in depopulating provinces. For Seoul, the Visa is one more national policy built to spread growth beyond it.

Common Questions

What is Seoul?

Seoul is the capital city of South Korea, home to roughly 10 million people and located about 50 km from the North Korean border. It is the country's political, financial, and cultural centre, and home to the KOSPI stock exchange.

Why did the KOSPI crash in March 2026?

South Korea's KOSPI fell 12% in a single session — its worst day on record — when the strait of Hormuz appeared to close during the Iran conflict. South Korea imports the bulk of its oil and LNG from Gulf sources, making it acutely sensitive to supply disruption.Source: Lowdown

How far is Seoul from North Korea?

Seoul is approximately 50 km south of the Demilitarised Zone (DMZ) that divides the Korean Peninsula. This proximity has defined Seoul's security posture for decades and makes THAAD missile defence a political priority.

How does the Iran war affect South Korea's economy?

South Korea is one of the world's largest importers of Gulf oil and LNG. Rising Brent Crude prices toward the $90-95 corridor triggered by the Iran conflict drive inflation and weaken export competitiveness. The KOSPI's 12% crash on the day Hormuz appeared closed was the most direct market signal.Source: Lowdown

Does the Iran war affect South Korea's missile defences?

Yes. The THAAD interceptor stock shared with US forces in The Gulf is the same arsenal that provides part of Seoul's layered defence against North Korean missiles. With 100-150 THAAD interceptors expended in the first eight days of the Iran conflict, replenishment is estimated to take two to three years.Source: Lowdown

Does Seoul qualify for South Korea's cheaper workation visa route?

No. The F-1-D Visa's lower income threshold, made permanent on 30 June 2026, applies only to under-35s settling outside Seoul, Incheon and Gyeonggi Province. Applicants choosing Seoul face the stricter, higher bar.Source: Korea Herald

How the World Sees Them

China

Beijing watches Seoul's economic distress from the Iran conflict as useful leverage: a South Korea weakened by energy shock is one more likely to soften its alignment with Washington. China's own restrained response to Hormuz tensions signals it is in no hurry to stabilise a crisis hurting a regional rival.

North Korea

Pyongyang reads every South Korean vulnerability as an opportunity. A Seoul distracted by market collapse, energy inflation, and depleted missile defences is exactly the strategic environment North Korea's leadership calculates against when assessing coercive options on the peninsula.

South Korea

Seoul anchors an economy structurally dependent on Gulf energy; any Hormuz disruption is felt first and hardest on the KOSPI. The 12% single-session crash in March 2026 confirmed the capital's exposure as a direct casualty of a war it plays no part in.

United States

Washington views Seoul as a frontline ally in Northeast Asia whose strategic deterrence depends on shared THAAD stocks. The Iran conflict is draining that shared arsenal faster than Lockheed Martin's Alabama plant can replenish it, creating a defence-resource tension Washington has not publicly resolved.
