日本参议院选举在即，野村称“这个可能性越来越大”：首相辞职、日美谈判停滞，日本面临加税

Core Viewpoint - A significant election in Japan is approaching, with increasing likelihood that the ruling coalition may lose its majority in the House of Councillors, which could lead to major political and economic implications, including the resignation of Prime Minister Shigeru Ishiba, a halt in US-Japan trade negotiations, and a reduction in interest rate hike expectations [1][2]. Group 1: Election and Political Implications - The ruling coalition (LDP and Komeito) is projected to win between 31-55 seats, with a majority requiring at least 50 seats, indicating a downward trend in expected seat numbers [1][2]. - Polls show a significant decline in the expected number of seats for the ruling coalition over time, with predictions dropping from 54-58 seats to as low as 41-53 seats [1][2]. Group 2: Economic and Market Impact - If the ruling coalition retains a majority (≥50 seats), the Ishiba administration will likely continue, and US-Japan trade negotiations will proceed as planned, potentially accelerating interest rate hikes and impacting the stock market negatively [2]. - Conversely, if the coalition secures fewer than 50 seats, it may lead to Ishiba's resignation, halting crucial trade negotiations and possibly increasing tariffs on Japanese imports from 10% to 25%, adversely affecting Japanese export companies [2]. Group 3: Potential New Government Policies - Even if the ruling coalition loses its majority, the LDP and Komeito may still govern due to their dominance in the House of Representatives, with potential candidates for LDP leadership identified [3]. - A new government is expected to adopt a more accommodative fiscal policy, focusing on measures to increase disposable income for households, such as welfare enhancements and reductions in social insurance fees [3]. Group 4: Market Reactions and Currency Fluctuations - The potential loss of seats by the ruling coalition could lead to mixed impacts on the stock market, with political uncertainty and stalled trade negotiations dampening market sentiment, while expectations of fiscal stimulus from a new government may provide some support [4]. - The anticipated delay in interest rate hikes by the Bank of Japan could result in a depreciation of the yen against the dollar, benefiting export-oriented sectors but putting pressure on financial stocks [4][5].
