Federal Reserve Chairman Warsh faces a severe test for next week's interest rate decision after the August CPI data release. The latest data shows that the US August core CPI rose by 0.3% month-on-month (above expectations), while the overall CPI rose by 0.4% month-on-month and 3.4% year-on-year. Analysts believe Warsh must choose between delivering on his previous inflation warnings and avoiding new market doubts about the central bank's control.

Previously, Warsh had repeatedly emphasized that the Federal Reserve should focus on prices and warned against over-reliance on short-term forecasts. However, some officials within the Federal Reserve, including Governor Waller, prefer to wait for more data before deciding whether to raise interest rates. In addition, Warsh also faces political pressure from US President Donald Trump to push for interest rate cuts.
