The yen extended its slide on Wednesday, pushing further past 160.00 per US dollar, a level often associated with potential Tokyo action, and the USD/JPY rate rose above 160.50 after news that Bank of Japan Governor Kazuho Ueda had been hospitalised. A BoJ statement gave no details on his condition, but said he will miss the 15-16 June monetary policy meeting; Deputy Governor Ryozo Himino will stand in, while Deputy Shinichi Uchida will deliver the post-decision press conference.
Markets broadly expect the BoJ to tighten by a quarter-point next week, taking the policy rate to 1%, the highest in more than 30 years, while attention is also on guidance for further tightening as the yen stays weak. Japanese authorities were reported to have spent JPY 11.7 trillion, or about USD 73.14 billion, on 30 April to support the currency, though the effect proved short-lived. Pressure has also been linked to high oil prices and comparatively low Japanese Government Bond yields, as expectations build for Federal Reserve rate rises; later, May US CPI data are expected to show inflation at a three-year high, a backdrop that could lift US Treasury yields and the dollar.
Volatility and Market Reactions to Ueda’s Hospitalization
We are watching the USD/JPY cross 160.50, a level that triggers significant concern from Japanese authorities. The sudden hospitalization of Governor Ueda introduces a high degree of uncertainty ahead of next week’s crucial policy meeting. This has caused one-week implied volatility for USD/JPY options to surge past 15%, a level not seen since the last intervention scare in late April.
All eyes are on the US CPI data due later today, which will be a key driver for the US Dollar. After the recent Non-Farm Payrolls report showed a robust addition of 295,000 jobs, economists are forecasting May’s core CPI to print at 0.4% month-over-month. A number at or above this forecast will likely strengthen the case for the Federal Reserve to maintain its hawkish stance.
Forward Guidance, Intervention, and Volatility Strategies
While a Bank of Japan rate hike to 1% is already factored into the market, we are more focused on the forward guidance from the press conference. The Ministry of Finance has shown its willingness to act, having spent nearly ¥12 trillion in a single day back on April 30th to defend the currency. This history suggests that any further spikes, perhaps towards 161.00, could be met with sudden and forceful intervention.
Given this outlook, we believe a simple long call strategy is too exposed to a sharp reversal from intervention. Instead, we are looking at bull call spreads, buying calls at 161.00 and selling them at 162.50 to cap both risk and reward. This structure allows us to profit from a continued upward drift while mitigating losses from a sudden yen-strengthening move by authorities.
For those who believe a significant move is imminent but are unsure of the direction, buying a one-week strangle is a viable strategy. This involves purchasing both an out-of-the-money call and an out-of-the-money put, profiting from the expected spike in volatility around the BoJ decision and US data releases. The elevated implied volatility makes this an expensive trade, but it covers the risk of a major surprise in either direction.
