The US consumer price index rose rapidly for the second consecutive month in September, highlighting the intention of the Federal Reserve to maintain higher interest rates for a longer period of time. The released data shows that the core CPI index, excluding food and energy costs, rose 0.3% last month. Economists believe that core indicators can better reflect potential inflation than overall CPI. Some analysts believe that recent inflation data highlights how a strong job market can support consumer demand, which may keep price pressures above the Federal Reserve's target. It is currently unclear whether this will make the central bank inclined to raise interest rates again this year, especially considering the recent surge in bond yields, which some officials suggest may replace more tightening policies. But at least it supports policymakers' desire to maintain high borrowing costs for a period of time.
