Summary

Park Byung-chang, CEO of MP Partners, discusses the market impact of potential Fed and BOJ rate hikes and the risk of yen carry trade unwinding. He argues that the first BOJ hike is less important than repeated hikes, which could narrow rate differentials and trigger carry unwinds, but immediate panic is not needed. He also sees a memory shortage and long-term supply contracts supporting Samsung Electronics and SK hynix, while near-term 3Q earnings and year-end sector rotation offer opportunities. He warns that high US Treasury yields and JGB stress could pressure risk assets.

  • BOJ rate hikes and yen carry trade unwind risk are the main macro focus.
  • Park says repeated BOJ hikes, not one hike, would be the real trigger for unwinding.
  • US big tech and long-term JGBs are flagged as vulnerable if carry unwinds.
  • Samsung Electronics and SK hynix are supported by memory shortage and LTAs.
  • 3Q earnings and strong Korean exports could act as a near-term catalyst.
  • Year-end rotation may favor Korean nuclear, power, infrastructure, security, and robotics stocks.
  • High US Treasury yields near 5% could make pensions prefer bonds over equities.
  • Park advises investors to prepare for volatility rather than simply waiting.
Ideas

BOJ hikes raise yen carry unwind risk.
The first BOJ rate hike is not the main issue, but repeated BOJ hikes will narrow rate differentials and raise the probability of yen carry trade unwinding. If Japanese rates reach 1.5-2%, unwinding becomes highly likely, causing global market tantrums and risk-asset volatility. Investors do not need to flee now, but they should be alert and monitor the risk into next year.
Park Byeong-chang Director, MP Partners 4:07
US big tech vulnerable to yen unwind.
If a yen carry trade unwind occurs, the most critical damage would likely be in the US because US big tech has enormous leverage. This makes US big tech the most fragile area to monitor or avoid in that unwind scenario.
Park Byeong-chang Director, MP Partners 6:13
Rising JGB yields pressure long-term Japanese bonds.
Japanese 10-year bond yields have risen to around 3%, causing losses for long-duration JGB holders. Japanese insurers and banks are selling long-term JGBs and shifting into short-term bonds, which can trigger margin calls and derivative spillovers into equities. This risk can recur each time rates rise.
Park Byeong-chang Director, MP Partners 10:28
5% Treasury yields may crowd out equities.
If the US 10-year Treasury yield reaches 5%, global pension funds with 5-6% annual return targets could meet those targets with safe US Treasuries, reducing the need to take risk in equities. This makes the 5% yield level an important threshold for risk appetite.
Park Byeong-chang Director, MP Partners 12:54
Memory shortage and LTAs support Samsung/SK hynix.
The memory upcycle remains intact: memory prices are rising, and industry leaders such as Jensen Huang and Chairman Chey say shortage conditions may last until 2028. Long-term supply agreements (LTAs) provide earnings stability, so Samsung Electronics and SK hynix are unlikely to reverse sharply and can eventually break previous highs. Near-term upside may be capped by rate hikes, but holding some exposure and waiting for the timing is reasonable.
Park Byeong-chang Director, MP Partners 21:29
Year-end rotation favors Korean nuclear, power, robotics.
As Samsung Electronics, SK hynix, and bank stocks consolidate, the Korean market is seeing a rotation into nuclear, power, infrastructure, security, and robotics stocks. These areas have already performed well during large-cap sideways moves and typically attract year-end rotational demand, creating short-term return opportunities even in a not-too-harsh market.
