USD/JPY Volatility Aftermath Continues | Battle Around the 157 Level Under Intervention Risk
■ Overview
Yesterday, USD/JPY saw a historic move:
- 160.72 → 155.57 (over 5 yen drop)
→ Triggered by strong verbal intervention from Japanese authorities
Today:
- Rebounded to the low 157 range and holding firm
👉 The market is now clearly:
“Waiting for the next move from authorities”
■ FX Moves
- USD/JPY: recovered from 155 → 157 range
- US Dollar Index: volatile, then back near 98
👉 This is not a USD-driven market
👉 It is a USD/JPY-driven market
■ Core Market Structure
“Intervention risk dominates everything”
- When price rises → intervention fear caps upside
- When price falls → dip buying emerges
👉 Result:
No sustained directional trend
■ Key Levels
- 50% retracement: 158.15
→ Important reference level - 160.00
→ Strongest intervention warning zone
👉 This area is extremely sensitive
■ Key Drivers Ahead
- Timing of the next move by Japanese authorities
- Oil prices (Middle East influence)
- Thin liquidity (Labor Day period)
👉 Combination:
Low liquidity × intervention risk = high volatility
■ Scenarios
① Move toward 158
→ Verbal or actual intervention risk increases
→ Upside capped
② Renewed JPY weakness
→ Retest of 160
→ High probability of intervention
③ Range continuation (most likely)
→ 156 – 158 range
■ Key Event Today
- ISM Manufacturing PMI
→ Forecast: 53.2
👉 However:
The real driver remains USD/JPY itself
■ Strategy
- Avoid large positions
- Respect key levels (158 / 160)
- Focus on short-term trading
■ Conclusion
This is now:
“A market driven by authorities, not fundamentals”
- If it rises → it gets capped
- If it falls → it rebounds
👉 The most important edge now is:
