Summary

Sonja Marten discusses why the US-Japan coordinated yen intervention is smarter and more credible than past unilateral moves, likely capping USD/JPY upside. She also warns that Fed Chair Warsh's communication style will increase bond market volatility, underlying inflation remains persistent, and equity markets are underpricing the risk of physical goods shortages from depleted strategic reserves.

  • Coordinated intervention with the US sends a strong signal that further yen support is possible.
  • Speculative short-yen positions have likely been wiped out, removing the 'free lunch'.
  • US Treasury using euros for the intervention was unusual and aimed at avoiding a strong-dollar policy clash.
  • Fed Chair Kevin Warsh's opaque communication could raise bond market volatility.
  • Underlying inflation remains elevated due to energy and food cost pressures.
  • The risk of physical goods shortages from drawn-down reserves is underpriced in record-high equities.

Coordinated intervention caps yen downside.
Coordinated US-Japan intervention is a much smarter move than Japan acting alone. It sends a very strong signal to markets that there could be further intervention, likely serving to draw a limit to further USD/JPY upside and wiping out speculative yen short positions. Speculating against the yen is no longer a free lunch.

Equities underpricing goods shortage risk.
The risk of physical goods shortages (excluding oil) is building as strategic reserves are being drawn down and cannot be replenished indefinitely. This risk is heavily underpriced in equity markets, which have just hit record highs, making equities vulnerable.
