Japan’s Nikkei hits record high after PM Ishiba resignation, strong Q2 GDP

Japan's Nikkei 225 index surged to a record high above 44,000, propelled by stronger-than-expected revised second-quarter GDP data showing a 2.2% annualized growth rate, driven by robust private consumption and inventory gains. Investor sentiment was further bolstered by Prime Minister Shigeru Ishiba's resignation, which ignited expectations for more expansionary fiscal and monetary policies and a potential delay in Bank of Japan tightening, alongside news of an impending U.S.-Japan deal to lower tariffs on auto exports.

Analysis

The Japanese equity market is exhibiting significant strength, with the Nikkei 225 index reaching a record high above 44,000, peaking at 44,185.7. This rally is underpinned by a confluence of positive catalysts. Firstly, revised economic data for the second quarter showed a stronger-than-expected annualized GDP expansion of 2.2%, a notable acceleration from the initial 1.0% estimate, driven by robust private consumption. Secondly, the abrupt resignation of Prime Minister Shigeru Ishiba has paradoxically fueled investor optimism; markets are pricing in the potential for a successor who will champion more expansionary fiscal and monetary policies, thereby creating expectations that the Bank of Japan may delay further policy tightening. Finally, sentiment is further supported by news of an impending U.S.-Japan trade agreement to lower tariffs on Japanese auto exports, providing a direct tailwind for a key sector. The market's broad-based strength is also reflected in the 0.2% gain in the wider TOPIX index, marking the fourth consecutive day of sharp advances for Japanese stocks.

Key Decisions for Investors

• Given the confluence of strong GDP growth, positive technical momentum, and expectations for continued accommodative policy, investors could consider maintaining or increasing long exposure to the Japanese equity market.
• The current rally is heavily predicated on political outcomes; therefore, closely monitor the LDP leadership contest and any forward guidance from the Bank of Japan, as a hawkish policy shift would challenge the prevailing market thesis.
• The impending U.S.-Japan deal to lower tariffs presents a specific catalyst, warranting a re-evaluation of positions in Japanese automotive exporters ahead of the mid-September timeline.
