美国总统特朗普已于2月1日签署行政令，宣布自2月4日起，对所有来自加拿大和墨西哥的进口商品加征 25%的关税，其中对加拿大石油征收10%的关税；同时，对来自中国的商品加征10%的关税。那么从历史 数据来看，加征关税对金融市场的影响究竟有多大呢？ 我们将基于历史关税事件的市场反应，深入分析金融市场及主要可投资指数的潜在波动。我们的分析基于 对以往关税在历史上所引发反应的观察。通过回顾过往关税政策实施首月对相关行业指数、国家可投资指 数及汇率的影响（若适用）。之所以选择分析首月的情况，是因为如果将时间延长到更长的时段，就很难 将当时由于宏观经济和政治决策所产生的其他影响因素单独分离出来。 探索历史关税对特定行业和国家的影响 以下两张历史图表显示，2018年1月美国针对进口太阳能组件和大型家用洗衣机征收的关税，以及2018年 3月对进口铝和钢铁征收的关税，对宽基股票、债券或波动性指数的价值影响微乎其微。任何一个指数的 下降似乎都与当时发生的其他宏观经济新闻或政治决策相关，比如2018年2月因劳动力市场利好和通胀数 据支持加息举措引发的市场波动。 | | 日期 | 中国宽基 股票指数 | 美国宽基 股票指数 | 教 ...

今天两市成交1.3万亿，量能进一步萎缩，1.3万亿差不多是本轮行情启动以来的最低表现，但今天个股表现不错，个股中位数+0.94%，除了微盘股指数 外，另外7个大盘指数全部上涨超过1%，分布很均衡。 中午的时候路透社援引国内两位线人的消息，称中国政府已经同意明年发行总规模3万亿人民币的特别国债，这将是最大规模的特别国债，用以增加经济 刺激的砝码。 经常会有读者问，为什么外媒总能率先报道重大消息，那肯定是国内传出去的。而且从逻辑上判断，很可能是经过许可后主动传出去的，否则泄露国家机 密信息就涉嫌间谍罪了。 关于这3万亿特别国债的用途也有说法，其中1万亿据说是要给国有银行补充资本，所以你们看银行股最近的涨势又好起来了，不单国内机构在增仓，摩 根、富达、普徕仕这些外资也在买。今天中证银行指数再涨1.33%，中、农、工、建四大行股价刷新史高。 另外2万亿里有超过一半会投向"两重"、"两新"。解释一下名次，两重是重大战略实施和重点领域安全能力建设，两新是大规模设备更新和消费品以旧换 新，以上领域会获得1万亿以上的资金刺激 。 剩下的钱会对生育进行补贴，以及投资新质生产力。 以上就是最新的饼，不管你们信不信，起码下午a股的 ...
