The yen is under renewed pressure at the start of the Asian week, with the US dollar attracting fresh safe-haven demand after weekend US–Iran peace talks broke down. Iranian negotiators walked out following threats from President Donald Trump to strike Iran again, after Tehran said on Saturday it would close the Strait of Hormuz in response to continued Israeli hostilities in Lebanon. Fox News reported further warnings from Trump, including a threat to take over the waterway.
The firmer dollar has pushed USD/JPY back towards last week’s peak near 161.80, the highest level since July 2024. Any further rise, however, remains constrained by the risk of Japanese forex intervention, which could lend support to JPY. That backdrop is reinforced by recent hawkish Bank of Japan commentary and signals from the April meeting minutes.
Safe-Haven Flows and Yen Volatility
We see the rising geopolitical tension in the Middle East as the primary driver for a stronger dollar. This safe-haven flow is pushing USD/JPY towards the 161.80 level, a key resistance point from last week. Implied volatility on one-month options has consequently spiked to 14.8%, signaling trader uncertainty about a sharp move.
Given this backdrop, we are looking at buying USD/JPY call options with strikes around 162.00 and 162.50. This strategy allows us to capture further upside if geopolitical fears continue to dominate the market. The key benefit is that our maximum loss is limited to the premium paid, which protects us from a sudden, sharp drop caused by intervention.
For those who believe a significant move is imminent but are unsure of the direction, a long straddle is worth considering. This involves buying both a call and a put option at the same strike price, profiting from a large price swing in either direction. We’ve seen moves of 3-5 yen in a single day during past interventions in 2022, making this a viable play for expected high volatility.
Crowded Positioning and Option Strategies
The market’s nervousness is also reflected in energy prices, with Brent crude futures pushing above $98 a barrel on fears of supply disruptions through the Strait of Hormuz. Recent CFTC data shows speculative net short positions on the yen remain near historic highs. This crowded positioning could fuel an aggressive price move on any new catalyst, either a military escalation or a surprise intervention.
We also favor using bull call spreads, such as buying the 162.00 call and selling the 163.50 call. This cheapens the cost of entry by capping the potential profit, which is a sensible trade-off given the high probability of intervention above 162.00. This structure allows us to position for a continued grind higher while acknowledging the very real ceiling the Bank of Japan is creating.
