South Korean prosecutors seek death penalty for former President Yoon on insurrection charge

Prosecutors have asked for the death penalty for former South Korean President Yoon Suk Yeol after a 17‑hour closing hearing, alleging he led an insurrection by attempting to impose martial law in December 2024; Yoon was impeached last April and has been on trial since. The request — notable given South Korea has not carried out an execution in nearly 30 years and insurrection is one of the few capital offenses — raises domestic political risk ahead of a Feb. 19 verdict at the Seoul Central District Court, though observers note execution remains unlikely based on historical precedent.

Analysis

Market structure: A conviction or protracted trial around the Feb 19 verdict increases short-term risk premia for Korea: exporters (Samsung 005930.KS, SK Hynix 000660.KS) gain from a weaker KRW while domestic cyclicals and banks (KB Financial 105560.KS, Shinhan 055550.KS) face margin pressure and deposit flight. Expect a 1–3% near-term depreciation in KRW and a 10–40bp rise in 2–10y KTB yields; KOSPI volatility (V-KOSPI) should spike, compressing liquidity in local equity and credit markets.

Risk assessment: Tail risks include large-scale unrest, emergency powers, or asset seizures (low prob <5% but high impact), and a political pardon that could reprice governance risk (medium prob ~15%). Immediate window (days–weeks) centers on protests/liquidity hits; short-term (1–3 months) on foreign investor flows and credit spreads; long-term (>=1 year) on structural reforms and foreign capital reallocation. Hidden dependency: foreign ownership (30–40% of market) amplifies outflow sensitivity to headlines.

Trade implications: Implement volatility and directional plays ahead of Feb 19: buy 3-month EWY 5–8% OTM put spreads (defined risk) and purchase 3-month USD/KRW call options sized to 1–2% portfolio exposure; short 2–5% positions in domestic bank-heavy KOSPI names (KB/SHINHAN) or via EWY. Tactical longs: 1–2% positions in defense beneficiaries (Hanwha Systems 272210.KS) on a 6–12 month horizon; hedge with 0.5–1% gold (GLD) or JPY exposure (FXY).

Contrarian angles: Consensus assumes protracted instability; history (Chun/Roh) shows legal outcomes often lead to commutation/pardons and rapid mean-reversion. If EWY falls >8% from current levels or USD/KRW >3% move, begin phased accumulation to 2–3% portfolio weight over 4–8 weeks; cover shorts if KOSPI implied vol retracts >40% from peak.

Key Decisions for Investors

• Establish a 2% portfolio short via EWY put spreads: buy 3-month EWY 5–8% OTM put spread sized to risk <0.5% NAV; target payoff if KOSPI falls >5% into Feb 19, exit or roll after 90 days.
• Buy USD/KRW 3-month call options sized to 1–2% portfolio exposure (delta targeting ~0.25) to hedge currency risk; set stop if USD/KRW move <1.5% or after 90 days.
• Short 2–3% positions in Korean banks (KB Financial 105560.KS, Shinhan 055550.KS) via CDS or stock if spreads widen >20bp and KOSPI falls >5%; cover whenstability returns or after 3 months.
• Allocate 1–2% long to Hanwha Systems (272210.KS) on view of higher defense spend if conviction increases political polarization; horizon 6–12 months, trim on +30% move.
• If EWY drops >8% or USD/KRW >3% within 2 weeks post-verdict, accumulate Korean equity exposure to 2–3% portfolio weight in phased buys over 4–8 weeks; exit if civil-unrest indicators (mass closures, curfews) trigger.
