台湾 #
The TAIEX closed the morning session down 2.88% at 45,398.87, with chip heavyweights leading the decline after another wave of foreign selling into the AI hardware complex. TSMC (2330.TW) and Hon Hai (2317.TW) faced renewed de-risking as investors reassess the sustainability of AI capex into 2027. Breadth was poor, with declines outpacing advances by a wide margin. The index has now given back a meaningful portion of its June gains, testing the 45,000 psychological support.
台湾加权指数午盘收45,398.87点，下跌2.88%。AI硬件板块再遭外资减码，台积电(2330.TW)与鸿海(2317.TW)等权值股领跌，市场重新评估2027年AI资本支出动能。盘面跌多涨少，指数回吐6月以来大部分涨幅，正测试45,000点整数关口支撑。
深度分析：台湾市场为何同步重挫 #
The synchronized drop in Taipei reflects a regional unwind of semiconductor exposure rather than Taiwan-specific news. Foreign investors have been net sellers of Asian tech for several sessions, using any headline around AI demand softness or margin compression as an excuse to de-gross crowded long positions. TSMC’s weighting near 35% of the index means every 1% move in the stock translates into roughly 30 index points; today’s selloff therefore had a mechanical amplification effect. Technical support is now seen around 44,800-45,000, with resistance at the 20-day moving average near 46,800.
台股重挫并非单一事件，而是亚洲半导体持仓同步去风险的结果。外资已连续数个交易日净卖出亚洲科技股，任何关于AI需求放缓或毛利压缩的消息都被当作减仓理由。台积电占台股权重约35%，其股价每波动1%约影响大盘30点，今日的跌势因此具有机械性放大效果。技术面看，下档支撑在44,800-45,000区间，上档阻力则位于20日均线约46,800附近。
韩国 #
KOSPI collapsed 10.47% to 7,433.96, triggering a full-market circuit breaker during the morning session as selling cascaded through Samsung Electronics and SK Hynix. The move extends a violent two-week unwind that has seen Korean equities experience multiple trading halts. Leveraged single-stock ETFs tied to the memory giants amplified the downside, forcing forced liquidations into an already thin order book. The won weakened to 1,509.38 per dollar, reflecting capital flight from the equity market.
韩国综合指数KOSPI暴跌10.47%，收报7,433.96点，早盘触发全市场熔断机制。三星电子与SK海力士遭遇抛售连锁反应，延续了过去两周剧烈去杠杠的行情。与这两大存储龙头挂钩的杠杆型单股ETF放大了跌幅，在委买盘稀疏的情况下触发强制平仓。韩元兑美元贬至1,509.38，反映股市资金外流压力。
深度分析：KOSPI暴跌的根源与传导 #
Today’s 10.47% drop marks the sixth circuit-breaker event for KOSPI in 2026 and the most severe single-session decline since the June 23 crash. The proximate catalyst remains the same: a reassessment of AI memory demand following Meta’s reported plan to monetize idle AI compute, which triggered fears of overcapacity in HBM and high-bandwidth memory. Samsung and SK Hynix together account for over 40% of KOSPI’s market cap; when both fall more than 10% simultaneously, the index has no natural buyers.
Beyond fundamentals, microstructure played a decisive role. Korean retail investors had piled into 2x leveraged ETFs on Samsung and SK Hynix, with aggregate AUM swelling from $3 billion to over $9 billion in less than a month. As the underlying stocks fell, these products were forced to sell to maintain leverage ratios, creating a reflexive spiral. The Korea Exchange has convened emergency meetings and is reportedly considering additional stability measures for leveraged products.
Valuation-wise, KOSPI has now fallen more than 20% from its June high of 9,385, entering a technical bear market. The next support zone is around 7,200-7,300, while a close below 7,000 would likely trigger further foreign outflows and potential sovereign fund intervention.
今日的10.47%跌幅是KOSPI在2026年第六次触发熔断，也是自6月23日崩跌以来最严峻的单日表现。直接导火索仍是AI存储需求被重新评估：此前有消息称Meta计划将其闲置AI算力对外出租，引发市场对HBM及高带宽存储产能过剩的担忧。三星电子与SK海力士合计占KOSPI市值逾四成，当两者同步跌逾10%，指数几乎没有自然买盘承接。
除了基本面，市场微观结构才是决定性因素。韩国散户大量涌入挂钩三星与SK海力士的2倍杠杆ETF，规模在不到一个月内从30亿美元暴增至逾90亿美元。随着标的股票下跌，这些产品被迫卖出以维持杠杆比例，形成越跌越卖的反射性螺旋。韩国交易所已召开紧急会议，据传正研拟针对杠杆产品的额外稳定措施。
估值方面，KOSPI自6月高点9,385已回落逾20%，进入技术性熊市。下档支撑区约在7,200-7,300，若收盘跌破7,000点，可能触发更大幅度外资流出，甚至引发主权基金入市干预。
日本 #
The Nikkei 225 shed 1.46% to 67,732.36, underperforming only slightly relative to the regional average but showing notable resilience compared with Seoul and Taipei. Exporters such as Toyota and Sony faced mild pressure from a weaker yen earlier in the session, though USD/JPY later stabilized near 162.38. Financials outperformed as the 10-year U.S. Treasury yield climbed toward 4.53%, improving net interest margin expectations for domestic banks.
日经225指数下跌1.46%，收报67,732.36点。相较于首尔与台北的崩盘，日股展现出一定韧性。丰田、索尼等出口商早盘因日元偏软承压，但美元兑日元随后稳定在162.38附近。金融股相对抗跌，因美国10年期国债收益率升至4.53%，提振国内银行净息差预期。
香港 #
The Hang Seng Index drifted 0.51% lower to 23,496.89, with losses concentrated in property and internet names while energy plays benefited from the oil rally. Southbound inflows remained robust, suggesting mainland investors continued to use Hong Kong as a proxy for risk assets. The Hang Seng Tech Index tracked Nasdaq futures lower but avoided the heavy selling seen in North Asian chip names.
恒生指数下跌0.51%，收报23,496.89点。地产与互联网板块领跌，能源股则受油价反弹提振。南向资金维持强劲流入，显示内地投资者仍透过港股作为风险资产的替代配置。恒生科技指数跟随纳斯达克期货走低，但跌幅远小于北亚芯片股。
中国 #
A-shares were softer across the board, with the CSI 300 down 1.03% at 4,792.26 and the Shanghai Composite off 1.26% at 3,990.24. Semiconductor and AI hardware names led the decline as the domestic chip complex tracked the regional sell-off. Utilities and oil majors provided relative support. Policy-sensitive sectors showed little reaction to the State Council’s approval of the 15th Five-Year tourism plan, with investors focused instead on global risk sentiment.
A股全线走弱，沪深300下跌1.03%至4,792.26点，上证综指下跌1.26%至3,990.24点。半导体与AI硬件板块跟随区域跌势领跌，公用事业与石油央企则提供相对支撑。国务院批复《旅游强国建设"十五五"规划》对政策敏感板块刺激有限，投资者更关注全球风险情绪变化。
资金流向 #
北向资金 #
今日行情数据未显示北向资金有效净买入（沪股通/深股通 net_buy 均为0.0），可能是数据延迟或统计口径未更新。昨日A股下跌期间，外资动向仍需等待港交所盘后披露确认。
南向资金 #
港股通（沪）净买入约48.83亿港元，港股通（深）净买入约52.40亿港元，合计南向净流入逾101亿港元。内地资金持续逢低吸纳港股，主要配置方向集中在高股息央企与互联网龙头。

地缘冲突追踪与板块影响 #
1. 伊朗战争 / 霍尔木兹海峡 #
最新态势（英文）: The Strait of Hormuz remains operating far below normal capacity, with daily transits running at roughly one-third of pre-crisis levels as IRGC naval forces continue to operate in the Omani corridor. Iran has repeatedly declared the strait “closed” to non-friendly vessels since late February 2026, and attacks on commercial tankers persist. WTI crude has repriced higher on renewed supply disruption fears, jumping 5.31% in the session.
最新态势（中文）: 霍尔木兹海峡通航能力仍远低于正常水平，日均通航量约为危机前三分之一。伊朗自2026年2月底起多次宣布海峡对"非友好国家"船只关闭，伊斯兰革命卫队海军持续在阿曼航道活动，商船遇袭事件仍时有发生。WTI原油因地缘供应中断担忧重估，日内跳涨5.31%。
| 板块 | 影响方向 | 代表标的 | 逻辑 |
|---|---|---|---|
| 石油勘探与生产 | 📈 | 中石油(0857.HK)、中石化(0386.HK)、ConocoPhillips | 油价风险溢价上升，上游盈利预期改善 |
| 油轮 / 航运 | 📈📉 | Frontline(FRO)、Euronav、招商轮船 | 运价与保险成本飙升，但航线中断限制运力周转 |
| 航空 | 📉 | 国泰航空(0293.HK)、中国国航(0753.HK)、ANA(9202.T) | 燃油成本上行，亚洲航线盈利受压 |
| 化工 / 炼化 | 📉 | 台塑(1301.TW)、LG化学(051910.KS) | 原料成本上升，下游需求疲弱挤压毛利 |
| 半导体 / 电子 | 📉 | 台积电(2330.TW)、三星电子(005930.KS)、SK海力士(000660.KS) | 区域风险偏好下降，且卡塔尔 helium/LNG 供应仍受限 |
关键时间节点: 7月中旬美国与伊朗相关方关于海峡通航的任何外交表态；OPEC+部长级会议前产油国是否会额外增产。
2. 俄乌战争 #
最新态势（英文）: The conflict remains entrenched, with European defense spending continuing to rise and energy sanctions on Russian exports largely unchanged. The war has become a background factor for Asian markets, though any escalation involving NATO infrastructure or Black Sea shipping could reignite energy and wheat price volatility.
最新态势（中文）: 俄乌冲突仍处僵持，欧洲防务开支持续增加，对俄能源出口制裁基本维持。该冲突对亚洲市场的影响已转为背景噪音，但若北约设施或黑海运粮通道出现升级，仍可能重新点燃能源与小麦价格波动。
| 板块 | 影响方向 | 代表标的 | 逻辑 |
|---|---|---|---|
| 欧洲防务供应链 | 📈 | Rheinmetall、BAE Systems、韩华航空(012450.KS) | 欧洲军费扩张带动订单 |
| 农产品 / 化肥 | 📈📉 | 中粮家佳康、Yara、Nutrien | 黑海谷物出口不确定性仍存 |
| 欧洲银行 | 📉 | UniCredit、Intesa Sanpaolo | 对俄风险敞口与地缘信用风险溢价 |
3. 全球关税 / 贸易冲突 #
最新态势（英文）: Trade tensions remain elevated heading into the second half of 2026, with the U.S. administration continuing to review reciprocal tariff measures against Asian exporters. Electronics and automotive supply chains remain the most exposed, though markets have largely priced in a baseline level of friction.
最新态势（中文）: 2026年下半年全球贸易紧张局势仍处于高位，美国政府持续审议对亚洲出口国的对等关税措施。电子与汽车供应链暴露度最高，但市场已基本计入一定基线水平的摩擦。
| 板块 | 影响方向 | 代表标的 | 逻辑 |
|---|---|---|---|
| EMS / 电子代工 | 📉 | 鸿海(2317.TW)、立讯精密(002475.SZ) | 关税成本转嫁能力有限 |
| 东南亚制造基地 | 📈 | 越南Vingroup、泰国Delta Electronics | 产能转移受益者 |
| 中国出口链 | 📉 | 家电、光伏、新能源汽车 | 美国关税与市场准入压力 |
