亚洲午盘 — 2026-07-03
市场概览 #
Asian benchmarks diverged sharply at midday Friday. Taiwan’s TAIEX jumped 3.65% on AI supply-chain buying, while Korea’s KOSPI tumbled 5.51% as semiconductor heavyweights were sold down. Japan’s Nikkei 225 was nearly flat, Hong Kong’s Hang Seng edged higher, and mainland China continued to weaken with the CSI 300 off 2.96%. The session reflected a broad repositioning out of richly valued tech growth into safe-haven assets and regional rotation opportunities.
亚洲主要指数周五午盘呈现极端分化。台湾加权指数在AI供应链买盘推动下大涨3.65%，而韩国KOSPI受半导体权重股抛售拖累重挫5.51%。日本日经225几乎持平，香港恒生指数小幅收高，A股则延续弱势，沪深300下跌2.96%。整体来看，资金正在从高估值科技成长股向避险资产和区域轮动机会重新配置。

台湾 #
Taiwan’s TAIEX surged 3.65% to 46,643.61, bucking the regional tech rout and finishing the morning session as the best-performing major benchmark in Asia. The move appeared driven by rotational buying into liquid AI-supply-chain names after several sessions of consolidation, with semiconductor foundry and server-component plays leading breadth. The iShares MSCI Taiwan ETF (EWT) closed the prior US session down 0.79%, suggesting the cash-market rebound in Taipei caught offshore positioning offside.
台湾加权指数大涨3.65%至46,643.61点，逆势成为亚洲主要市场中表现最强的指数。经过此前数个交易日整理后，资金轮动回补流动性较好的AI供应链标的，晶圆代工与服务器零组件板块领涨，市场广度显著改善。隔夜美股上市的iShares台湾ETF（EWT）收跌0.79%，显示离岸仓位对台北现货市场的反弹准备不足。
韩国 #
Korea’s KOSPI plunged 5.51% to 7,947.35, the weakest major Asian market, as foreign investors de-grossed exposure to semiconductor heavyweights. Samsung Electronics and SK Hynix continued to absorb the bulk of selling pressure, mirroring the recent pattern where chip-driven downside has dominated index-level moves. The Korean won weakened, with USD/KRW rising 0.57% to 1,544.04, adding pressure to foreign-carry positions.
韩国综合指数重挫5.51%至7,947.35点，为亚洲主要市场中最弱。外资继续减仓半导体权重股，三星电子与SK海力士承受主要卖压，延续了近期的“芯片主导指数”格局。韩元同步走弱，美元/韩元上涨0.57%至1,544.04，对外资套利仓位构成额外压力。
深度分析：The 5.51% drop ranks among the largest single-day declines since the March 4 Iran-war circuit-breaker session, underscoring how sensitive the KOSPI has become to any repricing of AI capital-spending expectations. Technical support now sits near the psychological 7,800 level, with the 7,500 handle as the next downside reference if foreign selling accelerates into the close. Breadth was heavily negative, and KOSDAQ-linked small caps also underperformed, indicating the selloff extended beyond the two megacap chipmakers. The EWY ETF fell 2.89% overnight, pointing to further potential downside in Seoul unless bargain-hunting emerges.
深度分析：本次5.51%的跌幅是自3月4日伊朗战争触发熔断以来的最大单日跌幅之一，显示KOSPI对AI资本支出预期的任何重新定价都极为敏感。技术支撑位先看7,800点整数关口，若外资卖压在尾盘加速，7,500点将成为下一下行参考。市场广度明显转差，科斯达克小型股同样跑输，说明抛售已不仅限于两大芯片巨头。隔夜EWY ETF下跌2.89%，除非首尔市场出现逢低买盘，否则短线仍有下探空间。
日本 #
Japan’s Nikkei 225 barely moved, edging down 0.04% to 69,441.39. The index balanced weakness in global semiconductor sentiment against a firmer yen and expectations of more measured Bank of Japan policy adjustments. USD/JPY slipped 0.38% to 161.17, providing some relief to domestic-focused sectors while continuing to weigh on exporters. The iShares Japan ETF (EWJ) closed up 0.10% in New York, showing relative resilience.
日经225指数几乎收平，微跌0.04%至69,441.39点。全球市场半导体情绪偏弱与日元走强、日本央行政策调整预期放缓相互抵消，指数呈现拉锯格局。美元/日元下跌0.38%至161.17，对内需板块构成一定支撑，但继续压制出口股。隔夜iShares日本ETF（EWJ）收涨0.10%，显示日股相对抗跌。
香港 #
Hong Kong’s Hang Seng Index closed the latest available session at 23,055.03, up 0.76%, supported by continued southbound buying and selective strength in internet and property names. Mainland investors remained net buyers through Stock Connect, with combined southbound inflows reaching approximately HKD 41.4 billion. The HSI outperformed mainland peers, partly reflecting a valuation gap and a more stable liquidity backdrop.
恒生指数最新收于23,055.03点，上涨0.76%，主要受南向资金持续流入及互联网、地产板块局部走强支撑。内地投资者通过港股通继续保持净买入，南向资金合计约414亿港元。恒生指数跑赢A股主要指数，部分反映了估值折价和相对稳定的流动性环境。
中国 #
Mainland China extended its recent pullback. The CSI 300 fell 2.96% to 4,812.30, the Shanghai Composite dropped 2.03% to 4,028.90, and the Shenzhen Component tumbled 3.85%. High-valuation technology and AI-related names led the decline as investors took profits ahead of the weekend and reassessed stretched positioning. Defensive sectors such as utilities and consumer staples saw relative bids, but breadth was weak with broad-based selling.
A股延续近期回调。沪深300下跌2.96%至4,812.30点，上证综指跌2.03%至4,028.90点，深证成指大跌3.85%。高估值科技与AI相关标的领跌，投资者在周末前获利了结并重新评估拥挤持仓。公用事业、必需消费等防御板块相对抗跌，但市场广度偏弱，抛压较为普遍。
深度分析：The 2.96% CSI 300 drop follows several sessions of narrowing breadth and signals a tactical de-risking in the most crowded growth trades. Northbound Stock Connect flows showed zero net-buy prints for both the Shanghai and Shenzhen boards, likely reflecting a holiday or data-collection pause rather than actual flat foreign positioning. The decline took the Shanghai Composite back below the 4,100 level, a key psychological marker, and raised the risk of further technical selling into the 3,950–4,000 support zone. Policy watchers will look for any verbal support from regulators or state-fund buying to stabilise sentiment.
深度分析：沪深300下跌2.96%，此前市场广度已连续收窄，显示最拥挤的成长交易正在战术性降风险。北向资金方面，沪股通与深股通净买入均显示为零，更可能是假期或数据采集暂停，而非外资实际零仓位。上证综指跌回4,100点心理关口下方，若技术面抛压延续，3,950–4,000区间将成为下一个支撑带。市场参与者将关注监管层表态或国家队资金是否入场稳定情绪。
资金流向 #
北向资金 #
北向资金（沪股通/深股通）当日净买入数据均显示为0.0亿元，推测为数据采集暂停或通道关闭，暂无法判断外资实际动向。前一交易日A股大跌已反映外资及机构对高估值成长股的减持。
南向资金 #
| 通道 | 净买入（亿港元） | 标的指数涨跌 |
|---|---|---|
| 港股通(沪) | 26.38 | 恒指 +1.57% |
| 港股通(深) | 14.98 | 恒指 +1.57% |
| 合计 | 41.36 | — |
南向资金合计净流入约41.36亿港元，继续成为港股流动性的重要支撑。内地资金对港股互联网及高股息板块的偏好未改。
汇率与宏观 #
| 品种 | 价格 | 涨跌幅 |
|---|---|---|
| 美元/日元 | 161.17 | -0.38% |
| 美元/人民币 | 6.7800 | -0.25% |
| 美元/韩元 | 1,544.04 | +0.57% |
| 美元/台币 | 31.96 | +0.36% |

| 美国10年期国债收益率 | 4.49% | +2.58% |
| 美元指数 | 100.79 | -0.32% |
黄金大涨4.23%至4,192.60美元，显示避险需求重新升温；WTI原油下跌2.50%至68.98美元，反映市场对霍尔木兹海峡局势阶段性缓和的定价。美国10年期国债收益率升至4.49%，美元指数小幅走弱。
地缘冲突追踪与板块影响 #
1. 伊朗战争 / 霍尔木兹海峡 #
Latest posture: US-Iran technical talks continue following the June 17 Islamabad memorandum of understanding, but implementation remains fragile. Iran’s IRGC re-declared the strait closed on June 20, while the foreign ministry contradicted that statement and shipping traffic has partially rebounded to around 40 crossings per day — still well below the pre-war average of 110. Disputes over tolls, frozen funds and sequencing of sanctions relief keep the risk premium elevated.
最新态势：6月17日伊斯兰堡谅解备忘录签署后，美伊技术谈判仍在继续，但落实过程脆弱。伊朗革命卫队6月20日再次宣布海峡关闭，外交部数小时后否认，实际航运流量部分恢复至每日约40艘次，仍远低于战前日均110艘次。通行费、冻结资金解冻及制裁解除顺序等争议使风险溢价维持高位。
| 板块 | 影响方向 | 代表标的 | 逻辑 |
|---|---|---|---|
| 国际油气 | 📈 | ExxonMobil(XOM), Chevron(CVX), ConocoPhillips(COP) | 供应中断风险支撑油价与上游利润 |
| 国防军工 | 📈 | RTX, Northrop Grumman(NOC), Lockheed Martin(LMT) | 中东及欧洲军费开支上行 |
| 黄金/贵金属 | 📈 | SPDR Gold(GLD), Newmont(NEM), Barrick(GOLD) | 避险与通胀对冲需求升温 |
| 航运/油轮 | 📉 | ZIM, Frontline(FRO), Maersk | 战争险保费飙升、运力绕航 |
| 航空 | 📉 | Delta(DAL), United(UAL), American(AAL) | 燃油成本占运营成本25–35% |
| 韩国半导体 | 📉 | Samsung(005930.KS), SK Hynix(000660.KS) | 外资减配高估值AI敞口 |
关键时间节点：60天临时停火/谈判窗口将在8月中旬到期。若届时未能达成最终协议，伊朗可能重新封锁海峡或恢复军事行动，油价与黄金可能再次跳升。
2. 俄乌战争 #
Latest posture: Western sanctions pressure continued through June. The EU adopted a “mini” sanctions package on June 15, the UK introduced new trade sanctions on May 19, and Ukraine extended its own sanctions lists. Peace talks have stalled, with the US and Russia holding only sporadic calls and Ukraine pressing for more Patriot missile deliveries.
最新态势：6月西方继续加大对俄制裁力度。欧盟6月15日通过“迷你”制裁方案，英国5月19日实施新贸易制裁，乌克兰也延长了制裁名单。和谈陷入停滞，美俄仅保持零星通话，乌克兰持续敦促美方增加爱国者导弹交付。
| 板块 | 影响方向 | 代表标的 | 逻辑 |
|---|---|---|---|
| 欧洲军工 | 📈 | Rheinmetall(RHM.DE), BAE Systems(BA.L) | 欧洲防务开支结构性上升 |
| 替代能源/LNG | 📈 | Cheniere(LNG), Shell(SHEL) | 欧洲能源去俄化需求 |
| 俄罗斯资产/银行 | 📉 | Sberbank, Gazprombank | 制裁、资产冻结与诉讼风险 |
| 德国工业 | 📉 | BASF(BASFn.DE), Siemens(SIE.DE) | 能源成本与出口订单承压 |
关键时间节点：欧盟对俄部门制裁有效期已延至2026年1月31日，下一次续审节点临近；冬季供暖季前（10月）能源供应安排将再次成为焦点。
3. 全球关税 / 贸易冲突 #
Latest posture: Tariff rhetoric remains a background risk. The Trump administration has threatened additional sectoral tariffs, while China-EU electric-vehicle duties and Japan-US trade negotiations continue. Asian exporters are managing supply-chain shifts and regional trade-diversion effects.
最新态势：关税言论仍是背景风险。特朗普政府威胁对特定行业加征关税，中欧电动车关税及日美贸易谈判仍在进行。亚洲出口商继续应对供应链转移与区域贸易分流效应。
| 板块 | 影响方向 | 代表标的 | 逻辑 |
|---|---|---|---|
| 墨西哥/东南亚制造 | 📈 | Foxconn(2354.TW), Delta Electronics(2308.TW) | 近岸与友岸外包受益 |
| 中国电动车 | 📉 | BYD(1211.HK), NIO(NIO) | 欧盟及潜在美国关税压力 |
| 美国零售/消费品 | 📉 | Walmart(WMT), Target(TGT) | 进口成本转嫁与需求放缓 |
关键时间节点：美国对中国及欧盟商品的关税复审窗口通常在季度末；8月前后可能出现新的关税公告。
