Reuters reported that:

“Iran’s Supreme Leader suggested maintaining near weapons-grade enriched uranium stockpiles.”

→ Markets immediately reacted with a risk-off response.

The Core of the Current Market

“A geopolitical safe-haven dollar rally driven by Middle East tensions.”

  • Rising oil prices
  • Higher U.S. yields
  • Weakening equities

→ A classic geopolitical dollar-buying environment.


Market Reaction

  • NY crude oil: rebounded from the $97 range back above $100
  • U.S. 10-year Treasury yield: rose toward 4.61%
  • USD/JPY: recovered back into the 159 range
  • EUR/USD: declined

However,

overall price moves remain relatively contained for now.

USD/JPY

USD/JPY rose toward the 159.17 area.

The rally is being supported by:

  • Iran-related headlines
  • Whether oil can remain above $100
  • The battle around 159–160 in USD/JPY
  • U.S. yield movements

→ Markets are especially vulnerable to sudden reactions from Middle East news flow.


Possible Scenarios Ahead

1) Middle East tensions escalate further

→ Oil prices remain elevated
→ Dollar strength continues
→ USD/JPY moves toward 160

2) Oil prices retreat

→ Dollar rally temporarily cools

3) Intervention concerns intensify

→ Risk of sharp USD/JPY reversal increases


Strategic View

  • Headlines remain the top priority
  • Watch oil prices and U.S. yields closely
  • Be cautious chasing USD/JPY higher in the 159 range

The current market can be summarized as:

“A geopolitical market driven by individual headlines.”

Iran-related developments
and the battle around the 159–160 zone in USD/JPY.
