Morgan Stanley’s Lord Says Worst May Be Over for Korean Won

Morgan Stanley strategist James Lord says the South Korean won, which recently endured its worst selloff since the 2008 financial crisis, may soon stabilize and even reverse some losses as expected US interest-rate cuts align with the end of Korea's policy-easing cycle. He notes near-term volatility will persist but argues monetary-policy shifts and easing trade tensions improve the risk-reward toward a recovery and potential outperformance of the currency.

Analysis

Market structure: A stabilizing or recovering KRW benefits Korean local-asset holders, importers, domestic bond investors and FX-hedged foreign buyers while pressuring large exporters’ USD revenue (Samsung, Hyundai) if appreciation is rapid; expect 3–8% directional moves over weeks as flows re-price. Ending BoK easing plus Fed cuts compresses carry differentials, shifting capital from USD cash into KRW-blend EM flows and Korean sovereign/IG credit.

Risk assessment: Near-term (days–weeks) elevated volatility persists (risk of 5–10% swings). Tail risks include renewed US-Korea trade flareups, BoK policy mistake, or a faster-than-expected US rate cut/vol spike that reverses KRW gains; monitor BoK minutes and Fed dot-plot changes in next 30–90 days as primary catalysts.

Trade implications: Direct plays: long KRW via NDFs or 3–6m call spreads and long Korea equity exposure (EWY) versus broad EM (EEM) capture relative recovery; volatility sell strategies (short-dated straddles) are attractive if IV > realized by >20% but require strict tail hedges. Expect cross-asset impact: local bond yields to tighten 10–40bp on sustained KRW strength, equity P/E expansions of 5–8% for domestic cyclicals.

Contrarian angles: Consensus assumes sustained FX outperformance only after Fed cuts — risk is market already priced for initial Fed dovishness; if Fed delays, short-term rebound can roll over. Historical parallels: 2003–2004 EM recoveries showed sharp 6–12% mean reverts then consolidation; position sizing and optionality are key to avoid being whipsawed.

Key Decisions for Investors

• Establish a 2–3% portfolio long in EWY (iShares MSCI South Korea) over 3–6 months, add on a confirmed BoK pause or dovish Fed signal within 30–90 days; set a hard stop-loss at -8% and trim if EWY outperforms EEM by >300bp in 30 days.
• Put on a tactical KRW long via 3-month call-spread (buy 3m KRW call, sell higher strike) sized to 1–2% portfolio notional if USD/KRW is within 5% of recent lows or after a BoK hawkish surprise; target 4–8% KRW appreciation, cap cost with sold call.
• Implement a relative-value pair: long EWY / short EEM equal notional (target 2% net exposure) to capture Korea-specific upside over EM for 3–6 months; close if spread narrows by >200bp or USD strengthens >4% vs basket in 30 days.
• Sell 1-month USD/KRW straddles only when FX implied vol >20% above 30-day realized vol; limit tail risk by buying a 3-month out-of-the-money put on USD/KRW (or long KRW calls) sized at 25% of premium collected and exit within 14–21 days if IV compresses <10%.
