美韩四重利空连环引爆：央行利率决议将近、英伟达CDS飙升、中国双喜，美韩半导体板块遭遇集中抛售

2026-07-28 13:15

ChainThink 消息，7 月 28 日，全球半导体相关交易承压，美股半导体板块率先下跌，英伟达收跌约 5%，费城半导体指数跌 2.23%；

亚洲交易时段，韩国、日本及港股 AI 硬件资产继续补跌，韩国 KOSPI 指数盘中跌超 10% 并两度触发熔断，SK 海力士、三星电子大幅下挫，南方两倍做多海力士 ETF、两倍做多三星电子 ETF 均跌超 20%。

本轮抛售主要受多重消息影响：据 The Information 报道，一家获中国国有资本支持的企业已开始量产自主研发浸没式 DUV 光刻设备，计划 2026 年生产约 5 台、2027 年扩大至约 20 台。

ASML 周一跌 5.80%，闪迪跌 11.02%，西部数据跌 4.21%。长鑫科技上市首日大涨 466%，也强化了市场对中国存储产业自给化提速的关注。

英伟达相关 AI 基建合作引发的信用风险担忧同步升温。据彭博报道，英伟达据称正讨论提供最高 2500 亿美元担保，帮助 OpenAI 从美国数据中心项目租赁算力；

公司还披露，与 SK Group 相关合作规模超过 5000 亿美元。

ICE Data Services 数据显示，英伟达 5 年期 CDS 一度上升约 14 个基点，最高至每年约 82 个基点，创相关合约活跃交易以来最大盘中涨幅。

AI 模型层面，月之暗面 Kimi K3 于 7 月 27 日开放模型权重，市场重新关注低成本高性能开源模型对 AI 资本开支效率的影响。

本周美联储和日央行将公布利率决议，市场对政策偏鹰的担忧也加重了高估值科技股和半导体股压力。
