As the holiday season concludes, markets are bracing for a high-risk September. The Federal Reserve, European Central Bank (ECB), and Bank of Japan (BOJ) will hold their monetary policy meetings consecutively, with the Federal Reserve and Bank of Japan (BOJ) meetings taking place in the same week. The Bank of Japan (BOJ) is expected to raise interest rates, while the European Central Bank (ECB) deposit rate is projected to increase by 25 basis points to 2.50%. Additionally, Anthropic plans an IPO with a funding target of up to $100 billion, which analysts warn could put AI-related stocks like NVIDIA and Microsoft under a stress test. European debt pressures (France's budget dispute, German state elections) and the direction of the UK's new government fiscal policy are also closely watched, while the energy price shock from the Iran war continues to erode global growth buffers.
