Conclusion: USD/JPY near 159 is not an ordinary carry trade: intervention risk can create gaps, slippage and rapid reversals. The key insight is that a profitable rate differential may be overwhelmed in minutes by official action or a hawkish BOJ repricing.
Reuters reported that the yen had surrendered roughly half the gains triggered by late-July and early-August intervention, reaching about 159.29 per dollar in the week to August 14. The market viewed 160 as a possible trigger zone, but that threshold was trader perception—not an official commitment.
| Risk | What can happen | Execution response |
|---|---|---|
| Official intervention | Abrupt yen strengthening | Reduce leverage; plan gap risk |
| BOJ repricing | Yield spread narrows | Track Japanese rates, not spot alone |
| Thin liquidity | Wider spreads and slippage | Avoid oversized market orders |
✓ Japan and the United States confirmed coordinated intervention in early August.
✓ Reuters said markets had sharply raised the probability of a September BOJ hike.
⚠ No precise future intervention level is confirmed. Rumours must not be presented as action.
