USDJPY at 155 Again, the Level That Forced BoJ Intervention in 2024
A convergence of AI-driven equity inflows and Hormuz-related haven demand has pushed DXY to 105 and the yen back to its 2024 intervention threshold. A surprise ceasefire or Fed shift could rapidly reverse both drivers, with EURUSD and CL=F the clearest collateral exposures.
RKey facts
- DXYThe US Dollar Index — trade-weighted USD against EUR, JPY, GBP, CAD, SEK, CHF. near 105 as of June 1-2, 2026
- USDJPY testing 155, matching the level that triggered BoJ intervention in 2024
- AI inflows into US equities supporting dollar demand from international investors
- Geopolitical haven demand amid Middle East conflict and Strait of Hormuz closure
- BoJ officials warning of potential intervention if yen weakness persists
What's happening
The US dollar is staging a sustained rally, with the DXYThe US Dollar Index — trade-weighted USD against EUR, JPY, GBP, CAD, SEK, CHF. climbing to nearly 105 and USDJPY approaching the 155 handle that forced Bank of Japan authorities to step in and defend the yen in 2024. This dual strength reflects two concurrent forces: genuine appetite for US risk assets on the back of AI enthusiasm, and simultaneous haven demand as US-Iran peace talks remain deadlocked and the Strait of Hormuz disruption persists. The combination is pushing yen weakness to levels that risk triggering a repeat of BoJ intervention.
AI-driven equity inflows into the US market are supporting dollar demand from international investors rotating into mega-cap tech names. Simultaneously, geopolitical risk premiums in oil and broader commodity markets are pushing investors into the greenback as a safe harbor. Trade flows and portfolio rebalancing are pulling in fresh dollar demand while carryIncome earned from holding a position over time. traders are re-evaluating their long-yen positions in light of elevated volatility. The BoJ has been notably cautious about the yen's weakness, and officials have warned repeatedly that further deterioration could prompt action.
The strength in the dollar is a headwind for commodity exporters and emerging-market currencies that fund themselves in dollars, while supporting US multinational earnings when translated back to dollars. However, the risk of BoJ intervention remains elevated if USDJPY breaches and holds above 155. Traders are watching for any verbal or actual jawboning from Japanese officials. Meanwhile, eurozone exporters face headwinds as EURUSD softens alongside the broader dollar rally.
A key risk to this narrative is a sudden ceasefire announcement in the Middle East conflict, which would reverse the geopolitical premium and potentially deflate haven demand for the dollar. Additionally, if the Fed signals a more hawkish stance than expected, the dollar could accelerate higher, putting even more pressure on the BoJ's tolerance threshold for yen weakness.
