Summary

Lee Jin-woo of GFM Investment Research Institute argues that dollar-yen is at a historic turning point and that broad U.S. dollar weakness and yen strength are increasingly likely. He explains why the U.S. is helping Japan resist yen weakness, how this could lower JGB yields, and why long-term U.S. Treasuries remain under pressure despite buybacks. He also says Bessent's policies may support U.S. equities even as bond and FX markets struggle.

  • Dollar-yen is at a long-term inflection after years of yen weakness.
  • The U.S. and Japan appear to want to stop yen weakness above 160.
  • Bessent warned speculators against betting on further yen weakness.
  • Broad dollar weakness would imply won, yen, euro, and yuan strength.
  • Falling dollar-yen may improve Japan's inflation outlook and lift JGB prices.
  • U.S. long-term Treasury yields are still rising despite buyback expansion.
  • U.S. equities may be supported by Bessent's market-supportive policies.
  • The interview also covers oil, geopolitics, and event risk.

Dollar-yen reversal points to yen strength.
The dollar-yen pair is at a historic inflection after a long period of yen weakness. Japan and the U.S. do not want yen weakness beyond 160, and the U.S. is helping because Japanese intervention funded by selling U.S. Treasuries would push U.S. yields higher. Bessent has warned speculators against betting on further yen weakness. If the cycle reverses, dollar-yen should fall toward at least 140, with potential for a much larger multi-year move.

EUR/JPY technical setup is bearish.
The U.S. Treasury sold euros and bought yen during recent intervention, and EUR/JPY has dropped. Technically, EUR/JPY looks bearish after failing to break higher, so it could fall further if key support gives way, although support makes the timing uncertain.

Broad U.S. dollar weakness is likely.
The dollar index is at a critical long-term average and trend point after the Fed and BOJ meetings. The speaker expects broad dollar weakness, which would mean strength in the Korean won, Japanese yen, euro, and Chinese yuan, as the U.S. also wants lower long-term yields and tolerates yen strength to avoid Treasury selling pressure.

Yen strength supports Japanese government bonds.
If yen strengthens, Japan's inflation outlook improves, which lifts Japanese government bond prices and lowers JGB yields. This would reverse the prior vicious cycle where yen weakness hurt inflation expectations, pressured JGB prices, raised yields, and fed fiscal credibility concerns. The virtuous cycle can pull dollar-yen and JGB yields lower together.

Bessent measures favor U.S. equities.
Bessent's policy measures are aimed at supporting the stock market. Although bond and FX markets may suffer, U.S. equities could welcome these actions because they are designed to prop up share prices.
Lee Jin-woo Director, GFM Investment Research 27:01
Long-term Treasuries remain under pressure.
Bessent's Treasury buyback expansion has not convinced the market; long-term U.S. Treasury yields continue to rise, with 10-year and 30-year yields under upward pressure. The market is skeptical of fiscal expansion and tariffs, so long-duration Treasuries remain vulnerable.
