USD/JPY has once again approached the critical 150-152 zone that triggered Japanese government intervention in 2022. With the pair trading at 150.80, we assess the intervention risk and what traders should watch for in the coming sessions.
Historical Intervention Context
Japan intervened in the currency market in September and October 2022 when USD/JPY crossed 150, spending approximately ยฅ9 trillion ($60 billion) to defend the yen. The interventions were effective in short-term terms but the pair eventually returned to similar levels due to the fundamental interest rate differential.
Current Risk Assessment
Several indicators suggest intervention risk is elevated:
- Finance Minister Suzuki has used increasingly strong language about “excessive moves”
- The speed of the yen’s depreciation (5% in 6 weeks) exceeds 2022 levels
- Japan’s foreign exchange reserves remain ample at $1.29 trillion
- US CPI next week could trigger rapid moves above 152
Trading Implications
The intervention risk creates an asymmetric setup above 151: potential gains are capped while downside from a sudden intervention could be significant (100-300 pips rapidly). Traders long USD/JPY should consider using options strategies to hedge intervention risk rather than carrying large naked long positions.
The best trade above 151 is often no trade. The risk-reward becomes unfavourable when you factor in the possibility of a coordinated intervention that could move the pair 300 pips in seconds.
