Japan’s ruling LDP party is organising a leadership vote on 4 October after Shigeru Ishiba resigned. His resignation followed a loss in the upper house election in July.
The announcement affected the Japanese yen, causing a lower opening in trading. Meanwhile, domestic equities experienced a relief rally as the market reacted.
New Party Leadership
The new party leadership will be confirmed in the coming month. This change in leadership is expected to impact both political and economic landscapes.
With the leadership vote scheduled for October 4th, we are seeing increased uncertainty, which is a key driver for derivatives pricing. The initial drop in the yen and the stock market rally suggest markets are optimistic about a change in leadership. We believe this environment is ideal for volatility-based strategies in the weeks leading up to the election.
The Nikkei Volatility Index has already climbed to 18.5, up from an average of 15 last month, reflecting market anticipation. We recommend considering buying Nikkei 225 index options, such as straddles, which profit from a significant price move in either direction before the vote. Looking back at the LDP leadership contest in 2021, the volatility index peaked just days before the vote, presenting a similar opportunity.
For currency traders, the yen’s weakness presents a clear trend to follow, with the USD/JPY pair now trading above 158. We expect the yen to remain under pressure if the front-running candidates continue to signal a commitment to monetary easing policies. Call options on USD/JPY with an expiration date after the October 4th vote could be a good way to capitalize on this potential further decline.
Equity Rally And Volatility
The equity rally in sectors like exporters is directly tied to this weaker yen. To play this, we see value in single-stock call options on major export-focused companies, which will benefit if the new leader reaffirms pro-growth stimulus. Data from Japan’s Ministry of Finance released just last week showed a 4.2% year-over-year increase in exports, a trend that a weaker yen would only accelerate.
As the election date nears, implied volatility will likely reach its peak, making options more expensive. The period immediately following the October 4th announcement will likely see a sharp drop in volatility as the uncertainty is resolved. This “volatility crush” means traders who bought options will need the market to move significantly just to break even, while those who sold volatility could see profits.
