Options Positioning
Given the market’s indecision around the 158.80 level, we see a clear mismatch between the calm currency price and the escalating geopolitical tension with Iran. The ceasefire deadline on Wednesday is a major binary event that the market seems to be underpricing. This complacency suggests that options, particularly those that protect against a sudden downturn, are attractively valued.
We should be positioning for a potential risk-off shock where the Japanese Yen regains its safe-haven status. Buying USD/JPY put options with expirations in the next few weeks offers a defined-risk way to profit from a breakdown in US-Iran talks. Such a strategy allows us to capitalize on a sharp move lower without being exposed to unlimited risk if the situation de-escalates and the pair resumes its uptrend.
A failure of the ceasefire could easily push WTI crude prices back toward the $100 mark, considering that roughly 21% of global petroleum liquids consumption passes through the Strait of Hormuz. We saw in early 2022 how the invasion of Ukraine sent oil prices soaring over 30% in just a couple of weeks, creating massive market volatility. While USD/JPY rose then due to interest rate policy, a direct conflict in the Gulf could trigger a far more aggressive flight to safety into the yen.
The key indicator to watch is implied volatility, which remains subdued despite the clear and present danger. We expect measures of currency volatility to spike significantly if Wednesday’s deadline passes without a peaceful resolution. Therefore, entering these protective positions now, before volatility gets expensive, is the prudent move.
From a technical standpoint, the 50-day moving average around 158.15 is the critical line of defense for the current uptrend. A break below this level on negative headlines would signal that the bullish structure is failing and could accelerate a move towards the 154.60 area. Our put options would gain significant value in such a scenario.
