10月29日外盘头条：美联储按兵不动苹果发布首款触屏笔记本电脑甲骨文大涨谷歌营收利润不及预期

可以写进 IB、A-Level、AP、IGCSE 经济学论文的真实新闻案例：货币政策与利率、需求拉动型通胀

发生了什么

美联储在担忧通胀的情况下仍决定维持利率不变，且有两名委员持反对意见。

经济学角度

这一事件可用于说明央行在通胀压力与利率决策之间的权衡：当通胀令人担忧时，按兵不动意味着货币政策保持现有紧缩或中性立场，利率不上升则借贷成本不变，总需求可能继续受到支撑，从而对物价形成上行压力。学生可以画出利率不变、投资与消费需求维持、物价压力延续的传导链条。

评估角度

但利率只是影响通胀的因素之一，供给冲击、财政政策与外部价格同样会推高物价；而且维持利率不变也可能是为了兼顾增长与就业，短期稳增长与长期控通胀之间存在取舍。

English version

What happened

The Federal Reserve kept interest rates unchanged despite concerns about inflation, with two members dissenting.

The economics

This illustrates the trade-off a central bank faces between inflation worries and its rate decision: holding rates steady keeps borrowing costs unchanged, which can continue to support aggregate demand and keep upward pressure on prices. Students can trace the chain from unchanged rates to sustained investment and consumption demand and to persistent price pressure.

Evaluation

However, interest rates are only one influence on inflation; supply shocks, fiscal policy and external prices also push prices up, and holding rates may be intended to protect growth and employment, so there is a short-run versus long-run trade-off between supporting output and controlling inflation.

Practice question

Using this example, analyse the possible macroeconomic effects of a central bank holding interest rates unchanged while it is concerned about inflation.
