Correlation With Equities Weaker In 2023, Equity Flows Lagging Kospi Rebound

KRW

1 month USD/KRW sits close to session highs currently, last near 1305 (highs were close to 1306.30), which is +0.30% on NY closing levels. This comes despite a weaker USD tone against the majors, albeit a modest one, while regional equities are higher (Kospi +0.96%).

  • The relationship between KRW and the Kospi has not been as strong in recent months, see the first chart. The current rolling 1 month correlation (in levels) is close to flat. For much of 2022 we were consistently in the -60/-80% range (i.e. higher local equities coincided with lower USD/KRW levels).
  • One possible driver of this weaker correlation has been the shift in the National Pension Service (NPS) FX hedging policy. The authority was asked to raise the ratio to 10% late last year to help curb USD demand.
  • Also note corporate FX deposits fell sharply in Feb, down nearly $12bn, the sharpest drop since 2012, which also be impact local FX supply/demand dynamics.
  • So, it remains to be seen when this correlation (between equities and the KRW) re-asserts itself.

  • It's also noteworthy that offshore equity flows have yet to return in a meaningful way, despite the Kospi being on a more stable footing in recent trading, see the second chart below.
  • All else equal, this will provide less flow support for the won, than otherwise might be the case. An improved flow picture can aid the won and perhaps help drive a fresh test sub 1300, but the market will likely want to see how the Fed decision unfolds later before flows return in a meaningful fashion.
