    Japan’s Prime Minister, Ishiba, has announced his resignation after losing the election. This comes at a tough time as the government has just completed a deal with the United States that needs approval from local lawmakers. His resignation might shake up Japanese markets and create uncertainty. However, the Nikkei index continues to rise, while the Japanese yen has weakened. The USD/JPY exchange rate has increased by 0.3%, reaching 147.10. This situation raises questions about how the Bank of Japan and political instability could affect market yields.

    Impact on Market Dynamics

    We see the resignation of the former defense minister as a key factor in causing market confusion. This political shift makes it harder to predict fiscal and monetary policy. Traders dealing in derivatives should brace for increased volatility in Japanese assets. With the yen falling past 147 against the dollar, we think the USD/JPY currency pair is likely to rise further. Buying call options on USD/JPY could be a wise move to benefit from this continued yen weakness due to the political changes. We’ll be keeping a close eye on the 150 level, as past data from late 2022 and 2023 suggests this is an important area for the Ministry of Finance to possibly intervene. The Nikkei’s rally is no surprise; it directly benefits from the yen’s decline. We see this as a chance to invest in futures to go long on the Nikkei 225 while expecting the yen to weaken further. The market currently favors the positive impact on exporter earnings, which have pushed the index to 34-year highs, rather than the ongoing political issues.

    Bond Yields and Political Risk

    The rise in Japanese government bond yields can be attributed to several factors. The Bank of Japan has signaled a move away from its strict yield curve control, with the 10-year Japanese Government Bond (JGB) yield recently exceeding 0.9% for the first time in a decade. The political risk from Ishiba’s exit adds to this trend, making bearish positions on JGB futures more appealing. In light of the mixed signals, we recommend strategies that can profit from price fluctuations instead of just one direction. Buying straddles or strangles on major Japanese equity ETFs could be a smart way to navigate the expected ups and downs. The Nikkei Volatility Index, which recently hovered around 18, is likely to rise, benefiting those who prepare for turbulence ahead of any potential snap election.
