大宗商品综述：油价大涨 铜价收窄周跌幅 金价下跌
可以写进 IB、A-Level、AP、IGCSE 经济学论文的真实新闻案例：供给冲击、供求与价格、成本推动型通胀
发生了什么
布伦特原油本周收于4月份以来最高水平，原因是沙特阿拉伯遭到的袭击愈演愈烈，加剧了此前已因美伊战争而升温的供应担忧。
经济学角度
这可以作为供给冲击的典型例子：地缘冲突威胁产油国的供给能力，使供给曲线向左移动，在需求不变时推高油价。学生可以画出供给左移的图形，说明价格上升、成交量可能下降。油价上涨还会通过运输和能源成本传导到其他商品，形成成本推动型通胀的压力。
评估角度
不过，油价能否持续上涨还取决于需求端和其他产油国是否增产，单一供给冲击的短期影响可能被长期调整削弱；同时产油国受益而石油进口国消费者受损。
练习题
结合该事例，分析地缘政治冲突如何通过供给冲击影响原油价格，并讨论其对通货膨胀的传导机制。

对应考纲
- 供给冲击：能源、粮食、供应链等突发变化使供给骤减或骤增，影响价格和产出。
- 供求与价格：某个市场的需求或供给变化，如何改变均衡价格和数量。
- 成本推动型通胀：工资、能源或原材料等生产成本上升，企业提价，导致物价上涨。

What happened
Brent crude ended the week at its highest level since April as escalating attacks on Saudi Arabia deepened supply worries already heightened by the US-Iran war.
The economics
This is a clear supply-shock example: geopolitical conflict threatens producers' ability to supply oil, shifting the supply curve left and raising the price when demand is unchanged. Students can draw the leftward shift to show a higher price and possibly lower quantity traded. Higher oil prices can also feed through transport and energy costs into cost-push inflationary pressure.
Evaluation
However, whether prices keep rising depends on demand and on whether other producers raise output, so a single supply shock may be offset over time; oil exporters gain while consumers in importing countries lose.
Practice question
Using this example, analyse how geopolitical conflict affects oil prices through a supply shock and discuss how this is transmitted to inflation.
