Article summary: Asia’s April 2026 reserve gains were mainly a valuation story: a weaker U.S. dollar raised the dollar value of non dollar reserve assets, with investment income and some surplus/intervention dynamics adding support..

2026年4月亚洲外汇储备增加，不能简单理解为各国央行突然大规模买入美元。更准确的说法是：外储是一篮子资产组合，里面不只有美元；当美元走弱时，非美元资产折算成美元后的账面价值会自然抬升，这就是所谓“估值效应” [24][

国际货币基金组织（IMF）的官方外汇储备币种构成数据库 COFER，跟踪的储备币种包括美元、欧元、人民币、日元、英镑、澳元、加元、瑞士法郎以及其他货币 [24]。这点很重要：外汇储备通常以美元口径公布，但储备资产本身可以分散在多种货币和资产中。
4月下旬的市场评论称，随着市场对美联储降息的预期升温、全球风险偏好改善，美元走弱 [2]。在这种环境下，央行持有的欧元、日元、英镑等非美元资产，即便数量没有明显变化，折算成美元后的总额也会增加。韩国央行相关报道就把这一机制说得很直接：美元兑主要货币下跌，提高了非美元资产的美元计价价值 [

韩国的数据最能说明问题。韩国央行数据经 ChosunBiz 和 Asia Today 报道显示，截至2026年4月底，韩国外汇储备为4278.8亿美元，较3月底增加42.2亿美元 [31][
34]。报道提到的原因包括汇率变动，以及外汇资产投资收益或运营收益增加 [
17][
34]。
韩国外储结构也提醒我们，外汇储备不是一堆“躺着不动的美元现金”。截至4月底，韩国外储中证券为3840.7亿美元，占89.8%；存款为187.6亿美元；特别提款权（SDR）为158.1亿美元；黄金为47.9亿美元；IMF储备头寸为44.5亿美元 [31]。也就是说，外储本质上是一个会受价格、汇率和收益影响的投资组合。
估值效应不是唯一可能因素。德国商业银行（Commerzbank）4月指出，中国、台湾和韩国的贸易及经常账户顺差上升，但相关货币对欧元仍偏弱，韩元甚至对美元也偏弱；该行将这种现象与系统性外汇干预联系起来，认为这有助于维持较低的实际汇率 [3]。
外汇干预的逻辑并不复杂：央行可以通过买入或卖出外币来影响汇率 [25]。如果出口或经常账户顺差带来外币流入，而当局为了限制本币升值而买入外币，外储就可能增加。但反过来，如果央行为了支撑走弱的本币而卖出外币，外储也可能下降。2026年3月的区域报道就提到，印尼、印度和台湾已采取干预以支持本币，中国则通过每日中间价释放支持人民币的信号 [

4月外储上升，并不能直接证明亚洲央行集体大举增持美元。公布出来的外储总额，往往同时包含汇率估值变化、投资收入、央行交易操作，以及不同储备资产结构带来的影响。韩国4月数据中，证券、存款、SDR、黄金和IMF储备头寸都被计入外储总额 [31]。
还有一个数据限制需要留意：中国国家外汇管理局公布官方外汇储备数据，IMF 的 COFER 数据库则追踪全球层面的储备币种构成 [40][
24]。但目前这些资料并没有给出一个完整的、逐个经济体拆分的明细，无法准确说明2026年4月亚洲主要经济体外储增加中，有多少来自估值、有多少来自投资收益，又有多少来自干预操作。
最有证据支撑的解释是：美元走弱抬高了既有非美元储备资产的美元估值。韩国4月外储增加42.2亿美元至4278.8亿美元，是这一机制的清晰案例，相关报道也把汇率变动和投资收益列为主要因素 [31][
34]。贸易顺差和外汇干预可能在部分经济体中提供额外支撑，但现有信息不足以给出整个亚洲范围的精确比例 [
