Summary

Lee Jin-woo of GFM Investment Research Institute discusses next-week BOJ and Fed meetings, assessing whether a BOJ rate hike could reignite yen carry trade unwind fears. He argues the carry unwind risk is overstated because the US-Japan rate gap remains wide and Japanese capital still needs US AI growth. He then analyzes USD/KRW, JPY/KRW around the 850 level, and the Korean stock market, saying KOSPI is still only a technical rebound and SK Hynix may need more time to resolve its chart.

  • Yen carry trade unwind fears are discussed ahead of the BOJ and Fed meetings.
  • The guest argues the US-Japan rate gap and Japan's lack of domestic growth reduce the likelihood of a severe unwind.
  • USD/KRW has fallen to the 1,340 area after policy pressure on exporters to convert dollars.
  • The 850 won per 100 yen level is highlighted as a critical cross-currency battleground.
  • KOSPI is described as still in a technical rebound with heavy overhead supply.
  • SK Hynix's chart is seen as facing resistance and possible ABC correction despite positive AI narratives.
  • Large memory chip exporters are said to be able to offset won strength through higher DRAM/NAND prices.
  • The guest advises caution and scenario-based preparation around Fed/BOJ events.
Ideas

Won strength likely faces policy resistance.
USD/KRW has fallen to the 1,340 area after Korean authorities pressured exporters to convert dollar revenues and after tax investigations and repeated meetings with exporters, while Fed/BOJ expectations also weighed on the dollar. But further won appreciation is uncertain: the authorities probably do not want the won to strengthen too much, and the next move depends on the Fed and BOJ. Watch whether USD/KRW can follow yen crosses lower or whether policy resistance keeps it supported.

Yen carry unwind fear is overdone.
The fear that the BOJ's next rate hike will trigger a 2008-style yen carry trade unwind is overdone. Even if the BOJ hikes to 1.25-1.50%, the US policy rate around 3.75% and market rate around 4.75% leave a wide rate gap; Japan also lacks domestic growth, so Japanese capital still needs to chase US AI growth. The BOJ is unlikely to tolerate excessive yen strength, and dollar-yen is unlikely to plunge sharply toward the yen. Therefore USD/JPY should remain supported rather than break down sharply.
Lee Jin-woo Director, GFM Investment Research 15:42
850 yen-won level is critical.
The 850 won per 100 yen level is the key battleground. If USD/JPY falls after the Fed and BOJ meetings but USD/KRW does not fall by the same amount because Korean authorities resist further won strength or local dollar demand persists, JPY/KRW will spike above 850 and trigger stops. If both USD/JPY and USD/KRW fall together, JPY/KRW should stay around 850.
Lee Jin-woo Director, GFM Investment Research 20:54
KOSPI remains a technical rebound.
KOSPI is still only in a technical rebound, not a sustainable trend. It has not cleanly broken above the 60-day moving average, and heavy overhead supply means foreign buying is needed to absorb it. The index may attempt a move toward the prior high, but the rebound is likely capped and range-bound until supply is cleared.
Lee Jin-woo Director, GFM Investment Research 21:51
SK Hynix faces ABC correction risk.
Large memory semiconductor exporters such as Samsung Electronics and SK Hynix can absorb the recent won strength because DRAM and NAND prices rose more than 20% in August, offsetting the 10%-plus currency move. This contrasts with smaller exporters that may face KIKO-like losses from FX derivatives bought when they expected won weakness.
