美联储政策动向影响全球市场，特朗普批评美联储理事，欧洲央行行长警示美国关税拖累欧元区经济。

Group 1: Federal Reserve Policy Dynamics - The Federal Reserve maintained the federal funds rate in the range of 4.25%-4.50% on May 8, 2025, signaling a potential future rate cut despite a 0.9% month-on-month increase in the PPI for July, which exceeded market expectations [1][3] - The July PPI reached its highest level since June 2022, indicating ongoing supply chain cost pressures, while non-farm employment growth was only 73,000, suggesting signs of a cooling labor market [3] - The dovish signals from the Federal Reserve have led to a rebound in global stock markets, but a weakening dollar may exacerbate capital flow pressures in emerging markets [3] Group 2: Trump's Criticism of the Federal Reserve - On August 19, 2025, Trump criticized Powell for maintaining high interest rates, claiming it harms the housing industry, and called for his resignation while suggesting a replacement [7] - Trump advocated for significant rate cuts, proposing a reduction of 300 basis points to stimulate the real estate market and economic growth, contrasting with the Fed's cautious approach to inflation [7] - Trump's scrutiny of the Federal Reserve's budget, particularly the renovation costs exceeding $1.9 billion to $2.5 billion, has raised questions about its management transparency [7] Group 3: European Central Bank Warnings - ECB President Lagarde indicated that U.S. tariffs on European goods could reduce Eurozone GDP by approximately 0.3 percentage points in the first year, with potential retaliatory measures from the EU increasing the impact to 0.5 percentage points [10][12] - The tariffs are expected to directly affect Eurozone manufacturing exports and temporarily raise inflation by about 0.5 percentage points, while long-term growth may be suppressed [12] - The Eurozone's economic growth forecast for 2025 is only 0.9%, with core inflation remaining low at 0.9%, limiting the ability to respond to imported inflation through interest rate hikes [12] Group 4: Interconnections and Global Impact - The conflict between Trump's rate cut demands and the Fed's data-dependent strategy increases policy uncertainty, affecting global confidence in dollar assets [15] - U.S. tariff policies are dragging down Eurozone growth through trade channels, creating a "lose-lose" situation as retaliatory measures raise import costs [15] - Emerging markets are compelled to raise interest rates to combat imported inflation, while the Eurozone faces a "low growth-low inflation" trap, limiting monetary policy options [15]
