日本股市创历史新高，可持续性存疑

Group 1 - The recent Japanese House of Representatives election resulted in a ruling coalition led by the Liberal Democratic Party and the Japan Innovation Party securing a majority of seats, which has led to a strong rally in the Japanese stock market and a slight rebound in the yen [1][2] - The Nikkei 225 index reached a historical high of 57,960.19 points following the election, driven by expectations of policy continuity and reduced risks regarding fiscal conditions [2][4] - The rise in the Japanese stock market is not reflective of domestic economic improvement but is instead driven by expectations of sustained government policies, overseas investments, yen carry trades, and the Bank of Japan's asset purchase program [4][5] Group 2 - The election results indicate that the Japanese government can maintain policy continuity, with Prime Minister Fumio Kishida committing to funding tax cuts through non-tax revenues rather than issuing deficit bonds, contrasting previous market concerns about excessive borrowing [4][5] - Japanese companies are increasingly focusing on overseas investments, with 50% of revenues for listed companies coming from international markets, and this trend is supported by low financing costs and yen carry trades [5][6] - The Bank of Japan is a significant buyer in the stock market, holding stocks worth 371.8 trillion yen, which accounts for 29.8% of the total market capitalization of the Tokyo Stock Exchange [6] Group 3 - Long-term uncertainties include fiscal sustainability, inflation expectations, and potential risks from Japan's "Japan First" defense and foreign policy, which could lead to increased instability in the Asia-Pacific region [8][9] - The continuation of loose fiscal policies may elevate inflation, leading to debt imbalances, as the weakening yen increases import prices, while real wages are experiencing negative growth [8][9] - If the Bank of Japan is forced to raise interest rates, it could reduce the attractiveness of carry trades, potentially leading to significant issues in the stock market and broader economy [9]
