Options traders prepare for increased yen volatility in case of Bank of Japan market intervention

As the market increasingly believes that Japanese authorities' intervention to support the yen could be unpredictable, options traders are bidding up the cost to hedge against potential sharp fluctuations in the yen ahead of the upcoming light trading period during the U.S. holiday.

The negative value of the one-week USD/JPY risk reversal indicator has deepened further, indicating a stronger demand for bullish yen options compared to bullish dollar options. Meanwhile, the one-week butterfly spread has widened, showing that investors are paying more to guard against large price swings in either direction.

Together, these moves indicate that traders are preparing for increased market volatility and are leaning towards yen appreciation, reflecting concerns that the Japanese government may intervene in the market. The lack of liquidity around the U.S. Independence Day holiday could amplify any sharp fluctuations in this currency pair.

Earlier this week, the yen fell to its weakest level against the dollar since 1986; it then rebounded nearly 1% on Thursday, driven by weaker-than-expected U.S. nonfarm payroll data, which led to dollar weakness. On Friday, after comments from Japan's Finance Minister Shunichi Katayama, the yen briefly broke above 161; she stated that the Bank of Japan is expected to take appropriate monetary policy actions to achieve its price targets.
