Summary

Hong Seon-ae hosts Shinhan Investment & Securities Dr. Kim Hyo-jin to discuss USD/KRW, US Treasury yields, inflation, and whether rate hikes are actually bearish for stocks. Kim sees the won's sharp rally as normalization with fair value near 1,290 and limited further downside. He argues US 10-year yields are tracking a Taylor Rule estimate near 5.1%, making near-term rate cuts unlikely, and he frames a September Fed hike as painful but better for KOSPI by year-end.

  • USD/KRW fell from about 1,560 to 1,340 as an abnormal dollar/won gap normalized.
  • Korea's current account surplus remains very large, supporting a stronger won.
  • Kim estimates fair USD/KRW near 1,290 and expects a mostly 1,300-1,400 range unless trade accelerates.
  • US 10-year Treasury yields are following the Taylor Rule, with fair value near 5.1%.
  • Broad PCE inflation components are still rising, so a soft CPI print may not quickly stabilize yields.
  • Kim sees a September Fed hike with hawkish rhetoric as preferable to prolonged uncertainty and better by year-end.
  • Historical comparisons show KOSPI suffered in 2022-23 when hikes were late/fast, but rallied after early gradual hikes in the 2010s.

USD/KRW has limited further downside now.
USD/KRW's sharp fall from about 1,560 to 1,340 is a normalization of an abnormal gap versus the dollar index. Korea is running an unusually large current account surplus, and Samsung Electronics/SK Hynix tax, ADR and exporter conversion flows helped flip the exchange rate trend. His dollar-index-based fair value is near 1,290, leaving only about 50 won of further downside from 1,340, so the risk-reward for fresh large USD/KRW shorts is poor. He expects USD/KRW to mostly swing between the 1,300 and 1,400 zone rather than collapse toward 1,200/1,100 unless the trade surplus accelerates or oil drops substantially.

US 10-year yields stay elevated toward 5%.
The US bond market is currently following the Taylor Rule rather than simply repricing oil or rate-cut/hike probabilities. His updated Taylor Rule calculation puts fair US 10-year yield near 5.1%, so the 10-year yield at about 4.8% can approach the widely watched 5% line. Rate-cut expectations are not being reflected in yields, and a soft CPI print alone is unlikely to reverse the trend because the bond market is watching broad PCE inflation components that are still rising. He does not expect a violent break far above 5%, but rapid rate cuts and a liquidity-driven rally are unlikely near term.

Don't panic-sell KOSPI on September hike.
Rate hikes are not mechanically bad for equities. The 2022-23 cycle hurt KOSPI because the Fed started late and hiked too rapidly, while in the 2010s and 2015 cycle, initial hikes led to sideways price action and then equities rallied, with Korea often among the strongest markets. A September Fed hike with hawkish rhetoric may cause immediate market pain, but it is preferable to dragging uncertainty into year-end. This sets KOSPI up as a watch for a buyable resolution rather than a signal to panic-sell.
