The Japanese yen initially surged on Monday following the results of Japan’s Upper House election, showing Prime Minister Ishiba’s ruling coalition lost its majority. Losing control in both the upper and lower houses, Japan anticipates political uncertainty.
The yen experienced fluctuations, initially increasing, retracting, then gaining again during European and US trading hours.
Japanese Government Bonds (JGBs) and equity futures showed little movement as the markets reopened following a holiday. Early signals suggest limited changes in response to the political developments.
Legislative Gridlock
The political upset for Ishiba’s coalition points towards legislative gridlock, making new fiscal stimulus unlikely. We see this as a headwind for domestic growth, a view supported by the Cabinet Office recently cutting its GDP forecast for the current fiscal year. Derivative traders should anticipate a period where government-led economic support is absent.
The yen’s strength, pushing the USD/JPY pair back from its recent 34-year highs above 160, is a logical reaction to this new reality. With less chance of large-scale fiscal spending that could weaken the currency, the yen may find a firmer footing. We are considering that yen volatility will increase, making long yen option strategies more attractive.
Nikkei 225 Risks
We believe the muted reaction in equity futures masks a developing risk for the Nikkei 225 index. A government unable to pass pro-business reforms or spending packages removes a key pillar of support for corporate earnings. This environment suggests positioning for downside by purchasing put options on the index.
The minimal change in government bonds confirms that the Bank of Japan, not the government, remains the primary driver for JGBs. With the 10-year yield already held near 1% by monetary policy, the election result is largely a non-event for this specific market. Traders should focus on the central bank’s next meeting for direction, not political headlines.
Historically, periods of a “twisted Diet” in Japan, such as the one following the 2007 election, have led to policy stagnation and market drift. This precedent suggests we should not expect any bold government action to jolt markets in either direction. Implied volatility in equity options may be underpricing this risk of prolonged indecision.
