2022年，俄罗斯被美国及其西方盟友冻结了约3000亿美元的外汇储备。这个动作本身改变了全球货币体系的逻辑基础——它告诉全世界：持有美元储备不只是一个收益率问题，还有政治风险问题。如果你和美国的关系出现裂痕，你攒了几十年的美元储备随时可能归零。

Foreign producers reduced their prices by 5.2 percent relative to the control group following the 25 percent tariff, absorbing about 20 percent of the tariff rate. The remaining 80 percent was passed forward as higher costs to US importers. On a bottle of wine for which the producer charged $5 before the tariff was imposed and $4.74 after, the tariff payment would have been $1.19. Importers, who the researchers estimate apply an 80 percent markup to the price they pay to producers, would have charged $9 to distributors before the tariff was imposed. The researchers estimate that they raised their prices to distributors by 5.4 percent, but on a base of $9 (= 1.8 x $5). This increase would be $0.49, so importers would be absorbing additional costs since they would pay $5.93 (= 1.25 x $4.74) to the producer and in tariffs. All told, the importer’s dollar margins per bottle declined by $0.44.。下载安装 谷歌浏览器 开启极速安全的 上网之旅。对此有专业解读
