美联储以需求工具应对供给冲击

关键论点

• 加息针对需求，但当前通胀多为供给驱动，因此对利率反应较弱。
• 非周期性通胀自2024年初以来趋于上升，占2026年7月核心PCE通胀的近三分之二。
• 医疗服务仅解释非周期性通胀的一小部分，且占比在下降，说明其他供给因素在起作用。
• 美联储旨在防止供给冲击扩散为普遍通胀，但存在削弱需求和伤害就业市场的风险。

2. Additional data from the San Francisco Fed shows that the recent rebound in PCE core inflation has been driven primarily by acyclical inflation.
3. (Again, this doesn't include energy prices.) Meanwhile, though cyclical inflation has ticked higher in recent months, as of July it was lower than it was a year earlier.
