亚洲午盘 — 2026-07-17

市场概览 #

亚洲市场在2026年7月17日午盘呈现极端分化：东北亚科技供应链遭遇系统性 de-grossing，台湾加权指数重挫4.82%，韩国KOSPI暴跌6.46%，日经225下跌5.52%；而香港恒生指数逆势收涨1.33%，A股跌幅相对温和。核心驱动力来自AI半导体估值修正、杠杆交易 unwind 以及伊朗战争对霍尔木兹海峡通航安全的持续扰动。WTI原油上涨1.34%至79.19美元，美元指数回落0.50%至100.77，黄金微跌0.10%至3,993美元。

指数表现 #

台湾 #

Taiwan’s TAIEX plunged 4.82% to 43,191.00 at midday, its sharpest single-session drop in months, as AI-server and semiconductor names faced aggressive foreign selling and futures-led de-grossing. The selloff follows a volatile week in which the index repeatedly tested the 45,000 level before giving way. TSMC (2330.TW) and Hon Hai Precision (2317.TW) led the decline, with the former under pressure from both valuation compression in the global AI trade and concerns that end-demand forecasts for high-bandwidth memory and advanced packaging are being marked down. Futures open interest and foreign positioning had been stretched long, making the unwind disorderly once the 44,500 support broke. The NT dollar weakened modestly, with USD/TWD rising 0.70% to 32.33, reflecting some safe-haven flow into the greenback.

台湾加权指数午盘暴跌4.82%至43,191.00点，为数月来最大单日跌幅，AI服务器与半导体板块遭遇外资 aggressive selling 与期货去杠杆。指数本周多次测试45,000点关口后终告失守，台积电(2330.TW)与鸿海(2317.TW)领跌，前者同时承压于全球AI交易估值压缩，以及市场下调高带宽存储与先进封装需求预期的担忧。期货持仓与外资多单过度拥挤，一旦44,500点支撑位失守，平仓连锁反应迅速放大。新台币小幅走弱，美元/台币上涨0.70%至32.33，显示部分避险资金流向美元。

韩国 #

KOSPI collapsed 6.46% to 6,820.60, extending its technical bear market after the index had already fallen more than 20% from its late-June record high. The catalyst was another leg down in the AI-semiconductor complex: SK Hynix (000660.KS) dropped nearly 11% and Samsung Electronics (005930.KS) fell more than 7%, with the two stocks accounting for roughly half of the benchmark’s market capitalization. The Korea Exchange triggered a sell-side sidecar early in the session after KOSPI 200 futures fell more than 5%, the latest in a series of volatility halts that have become routine in July. Foreign investors remained net sellers, while local retail traders attempted to absorb the supply. The damage was amplified by record retail margin debt and leveraged single-stock ETFs that had built up during the first-half rally. Macro policy added to the pressure: the Bank of Korea has removed easing guidance and is now priced for rate hikes, while the won firmed 1.19% against the dollar to 1,480.62, doing no favors to export earnings estimates.

韩国KOSPI暴跌6.46%至6,820.60点，延续技术性熊市，指数已较6月下旬历史高点回撤逾20%。导火索是AI半导体板块再遭重击：SK海力士(000660.KS)跌近11%，三星电子(005930.KS)跌逾7%，两家公司合计约占KOSPI总市值的一半。韩国交易所早盘在KOSPI 200期货跌幅超过5%后启动卖方 sidecar 暂停程序化卖单，这是7月以来多次波动率熔断中的最新一次。外资维持净卖出，本地散户试图承接，但上半年涨势中累积的创纪录零售融资余额与杠杆个股ETF放大了跌势。宏观政策同样构成压力：韩国央行已删除降息措辞，市场定价年内加息；韩元兑美元升值1.19%至1,480.62，对出口企业盈利预期不利。

日本 #

Nikkei 225 tumbled 5.52% to 63,531.50, the worst regional performance outside Korea, as semiconductor equipment and technology conglomerates sold off in sympathy with Seoul and Taipei. Advantest (6857.T), Tokyo Electron (8035.T), SoftBank Group (9984.T) and Renesas Electronics (6723.T) all declined between 4% and 7% in the previous session, and the weakness carried over. The yen’s relative stability—USD/JPY was up only 0.34% at 162.42—meant exporters did not benefit from the weak-currency narrative that had supported the market earlier in the year. With the Bank of Japan maintaining a hawkish bias and real yields rising, long-duration growth stocks were particularly vulnerable. The drop pushed the Nikkei through its 50-day and 100-day moving averages, triggering CTA and momentum-reversal selling that may extend into the New York close.

日经225重挫5.52%至63,531.50点，为除韩国外区域表现最差，半导体设备与科技综合股随首尔与台北同步大跌。爱德万测试(6857.T)、东京电子(8035.T)、软银集团(9984.T)与瑞萨电子(6723.T)在前一交易日跌幅介于4%-7%，弱势延续至今日。日元相对持稳，美元/日元仅上涨0.34%至162.42，出口商未能获得年初以来弱日元叙事的支持。日本央行维持鹰派立场、实际收益率上升，使长久期成长股尤为脆弱。指数跌破50日与100日均线后，触发CTA与动量反转卖盘，可能延续至纽约收盘。

香港 #

Hong Kong’s Hang Seng Index bucked the regional rout, rising 1.33% to 25,008.60 in a session characterized by rotation out of Northeast Asian tech into China-linked value and yield plays. The Hang Seng Tech Index initially fell more than 4% before trimming losses, but the broader benchmark was supported by property, financials and energy names that had already de-rated sharply in the second quarter. Southbound flows were mixed: Shanghai Connect recorded a net inflow of HKD 4.71 billion, while Shenzhen Connect saw a net outflow of HKD 3.74 billion, leaving a modest net purchase of around HKD 970 million. The relative resilience suggests global funds are treating Hong Kong as a China recovery proxy rather than a semiconductor beta trade, though the afternoon session remains exposed to any further deterioration in US futures.

香港恒生指数逆势上涨1.33%至25,008.60点，资金从东北亚科技板块轮转至中国相关价值与收益型标的。恒生科技指数早盘一度跌超4%，随后收窄跌幅，但大盘受地产、金融与能源板块支撑，这些板块在第二季度已大幅下修。南向资金分化：沪股通净买入47.10亿港元，深股通净卖出37.37亿港元，合计净买入约9.73亿港元。相对韧性显示全球资金将港股视为中国复苏代理，而非半导体贝塔交易，但下午盘仍受美国期货进一步恶化影响。

中国 #

A-shares declined but outperformed their Northeast Asian peers, with the CSI 300 down 1.85% to 4,698.43 and the Shanghai Composite off 1.85% to 3,882.41. The Shenzhen Component fell 1.97% to 14,488.65. The market was led lower by CPO/optical communication, computing hardware and precious-metals names, while financials—particularly brokerages—staged a late-morning rally on reports of major state-owned enterprise restructuring. The session was also marked by heavy turnover in memory and chip-design names as investors reassessed AI capital-spending narratives. Northbound flows were effectively flat, with both Shanghai and Shenzhen Connects reporting zero net buying, indicating foreign investors were on the sidelines ahead of the weekend. Policy expectations remain the key support; any stabilization message from the central bank or state funds would be the catalyst for a bounce.

A股下跌但跑赢东北亚同业，沪深300跌1.85%至4,698.43点，上证综指跌1.85%至3,882.41点，深证成指跌1.97%至14,488.65点。CPO/光通信、算力硬件与贵金属板块领跌，而金融股—特别是券商—在三大央企合并重组消息带动下逆势拉升。存储与芯片设计个股成交活跃，投资者重新评估AI资本开支叙事。北向资金基本归零，沪股通与深股通均显示零净买入，表明外资在周末前持观望态度。政策预期仍是关键支撑，央行或国家队任何维稳信号都可能成为反弹催化剂。

资金流向 #

北向资金 #

北向资金今日净买入接近零。沪股通与深股通均报净买入0.00亿元，显示外资在区域科技抛售潮中按兵不动。考虑到A股跌幅明显小于日韩台市场，外资并未出现恐慌性撤离，但也缺乏主动配置意愿。

南向资金 #

南向资金小幅净流入。沪股通(港股通)净买入47.10亿港元，深股通(港股通)净卖出37.37亿港元，合计净买入约9.73亿港元。资金结构显示内地投资者对低估值港股仍有兴趣，但南下资金在科技板块分歧较大。

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

The US-Iran confrontation has re-entered an active military phase. CENTCOM reported strikes on approximately 90 Iranian military targets on 8 July, targeting air defenses, coastal surveillance, missile and drone storage, naval assets and logistics infrastructure. Iran has retaliated against US-aligned Gulf states and threatened to keep the Strait of Hormuz from returning to its previous status. Associated Press reporting indicated only 14 vessels recently transited the strait on one Sunday, versus roughly 130 per day before the war. Diplomatic talks continue but the ceasefire is fragile.

美国与伊朗对抗重新进入 active military phase。美国中央司令部称7月8日对约90个伊朗军事目标实施打击，目标包括防空系统、沿海监视设施、导弹与无人机仓库、海军资产及后勤基础设施。伊朗已对亲美海湾国家实施报复，并威胁霍尔木兹海峡不会恢复战前状态。美联社报道称，某周日仅有14艘船只通过该海峡，而战前约为每日130艘。外交谈判仍在继续，但停火协议脆弱。

受影响板块分析

关键时间节点

• 7月24日：美国10%全球附加关税到期，可能伴随新的 Section 301 行动。
• 7月下旬至8月初：若霍尔木兹通航数据未改善，油价可能测试85美元/桶。

2. 全球关税 / 贸易冲突 #

最新态势

The US finalized a 25% Section 301 tariff on Brazilian imports effective 22 July, covering digital trade, IP, ethanol and deforestation disputes, with exemptions for coffee, beef and aerospace parts. Separately, a bipartisan Senate bill introduced this week would authorize tariffs of up to 100% on the top five purchasers of Russian crude and natural gas, a group that includes China and India. The US-China tariff truce reached in late 2025 is due to expire in November 2026, and the two sides have yet to agree on an extension or a framework for mutual tariff reductions.

美国 finalized 7月22日对巴西进口商品加征25%的 Section 301 关税，涉及数字贸易、知识产权、乙醇和毁林争端，咖啡、牛肉及航空零部件除外。此外，本周一项两党参议院法案拟授权对前五大俄罗斯原油和天然气买家征收最高100%关税，其中包括中国和印度。2025年底达成的中美关税休战将于2026年11月到期，双方尚未就延期或互降关税框架达成协议。

受影响板块分析

关键时间节点

• 7月22日：美国对巴西25%关税生效。
• 11月：中美关税休战到期，预计8-9月进入密集谈判期。

3. 俄乌战争 #

最新态势

No major battlefield breakthroughs were reported today, but Russia’s energy infrastructure remains a focus of Western sanctions and Ukrainian strikes. The Senate bill targeting buyers of Russian energy signals a new phase of secondary sanctions that could reshape global oil and gas trade routes.

今日无重大战场突破报道，但俄罗斯能源基础设施仍是西方制裁与乌克兰打击焦点。针对俄罗斯能源买家的参议院法案标志着次级制裁进入新阶段，可能重塑全球油气贸易路线。

受影响板块分析

关键时间节点

• 7月24日：美国全球附加关税到期，可能同步升级对俄能源制裁。
