What changed
This is the first weekly reading, so there is no previous score or regime to compare. The region opens at +19, ranked 4th overall; Taiwan scores +26 with a bullish tilt and South Korea +2. Economic momentum (+44) and market performance (+37) are strongest; geopolitics (-20) and capital flows (-6) are weakest.
Economy and markets
The IMF’s October 2026 outlook raised Korea’s 2026 growth to 3.3% (from 2.6%) and more than doubled Taiwan’s to 10.7% (from 5.2%); CIER now sees Taiwan at 12.16%, the fastest since 1987. Regional equities are up about 57% year to date and 65% over a year, but fell 13% in the past month, with Korea down about 20% and Taiwan 8%. Against the MSCI ACWI the region lags by 3.2 points over three months but leads by 5.8 over six; Taiwan leads on both, Korea lags on both. Valuations split sharply: MSCI Korea at 4.9x forward earnings against MSCI Taiwan at 18.7x.
Capital flows and rotation
The model reads a stable trend, with three-month ETF flows of about +3.2% of fund size, but the region has moved into the Weakening quadrant. Hard data show heavy foreign withdrawals: KRW19.0tn from Korean stocks in 1-23 October (about 75% in SK hynix and Samsung) and a record NT$302.6bn in Taiwan on 15 October. The IIF says Korea led a $19.2bn EM equity outflow in September.
Currency
KRW scores +35.2 and TWD +3.9, both with upward one-year views (MUFG sees 1,300 and 30.9 per dollar). Longer term, KRW is two-way and TWD flat to higher. Firmer currencies would add to USD-based investors’ returns; for EUR and GBP-based investors the effect also depends on their own currency against the dollar, so check the heatmap.
Risks and what to watch
Geopolitical risk is high: cross-Strait tensions, the US-Iran conflict and oil, plus doubts over AI capex and the memory cycle. Watch the 27-28 Oct FOMC; late-October Korea and Taiwan Q3 advance GDP; Samsung and SK hynix results; hyperscaler capex guidance in late-October US earnings; and October export orders.
