亚洲午盘 — 2026-07-30

市场概览 #

北亚半导体杠杆泡沫的出清在今日演变为全面踩踏。韩国 KOSPI 午盘快照报 5,584.43 点、单日重挫 21.31%，按韩国交易所规则（跌幅达 20% 当日休市）已触发最高级别熔断，这已是 2026 年内第八次熔断、且是首次触及休市线；台股加权指数跟跌 7.53% 至 40,367.24 点，日经 225 跌 4.43% 至 61,746.79 点。与之形成鲜明对照的是资金的明确轮动方向：印度 SENSEX 涨 2.03%、新加坡 STI 涨 1.57%、澳洲 ASX 200 涨 1.44%。地缘面上，美军今日宣布结束对伊朗的新一轮大规模打击、但海上封锁持续，WTI 升至 83.70 美元；美债 10 年期收益率回落 8bp 至 4.62%，典型的避险买盘特征。

台湾 #

Taiwan’s TAIEX was caught directly in the crossfire of the Korean deleveraging cascade, sliding 7.53% to 40,367.24 by midday — one of the worst single sessions in its history. The transmission channel is straightforward: Korea’s forced liquidation of Samsung Electronics and SK Hynix positions is repricing the entire global memory and AI-compute complex, and TSMC (2330.TW), as the foundry anchor of that trade, absorbed indiscriminate de-grossing from regional long-only and quant funds. The overnight ADR signal was unambiguous — EWT fell 4.83% in New York with volume near 9.7 million units — and local breadth this morning was one-way, with foreign institutions net selling across the board. The Taiwan dollar weakened modestly (USD/TWD +0.44% to 32.44), orderly enough to suggest the central bank is tolerating rather than resisting the move. Watch whether the FSC tightens short-sale rules again; a similar playbook was deployed during the April 2025 tariff shock.

台股被韩国去杠杆风暴直接击中，加权指数午盘重挫 7.53% 至 40,367.24 点，为史上最惨烈的单日表现之一。传导链条很清晰：韩国市场对三星电子、SK海力士的强制平仓正在重新定价全球存储与 AI 算力板块，而台积电(2330.TW)作为这条主线的晶圆代工锚，遭遇了区域型长线基金和量化基金无差别的降仓（de-grossing）。隔夜 ADR 信号已经写明方向——EWT 在纽约跌 4.83%、成交近 970 万单位；今早本地盘面呈单边下跌，外资全线净卖出。台币小幅走贬（美元/台币 +0.44% 至 32.44)，节奏尚属有序，显示央行选择容忍而非对抗。后续观察金管会是否再度收紧融券规则——2025 年 4 月关税冲击时曾用过同一套工具。

韩国 #

This is no longer a correction; it is a structural deleveraging event. KOSPI’s midday print of 5,584.43, down 21.31% on the session, crossed the exchange’s third-tier circuit breaker threshold (-20%), which mandates a full-day trading halt — the first time this ultimate brake has been hit in the 2026 crash cycle, and the eighth circuit breaker year-to-date. The mechanics are by now well documented but worth restating: the April 2026 approval of 2x single-stock leveraged ETFs on Samsung Electronics and SK Hynix drew in over KRW 14 trillion of retail money; the daily-reset leverage turned a semiconductor pullback into a self-reinforcing liquidation spiral, with over 1.2 million leveraged accounts hitting margin calls since July 13. The index has now fallen roughly 39% from its late-June record of 9,115. Yesterday’s -10.84% close was supposed to be capitulation; today’s tape says otherwise — SK Hynix (000660.KS) and Samsung Electronics (005930.KS) remain locked in limit-down-type selling as ETF redemption and forced liquidation flows feed on each other. The one anomaly worth flagging: USD/KRW fell 2.36% to 1,439.18 (won strengthening), a move consistent with suspected BOK intervention or state-entity dollar selling to stabilize the FX channel. Regulators’ July 16 package (higher cash margins, ban on securities collateral) has not stopped the bleeding; the market is now pricing a policy response — an emergency liquidity facility or a temporary buy-side stabilization fund — within days, not weeks.

这已经不是回调，而是一场结构性的去杠杆事件。KOSPI 午盘报 5,584.43 点、单日暴跌 21.31%，越过交易所三级熔断阈值（-20%）——按规则将当日直接休市，这是 2026 年崩盘周期中首次触发这条"终极刹车"，也是年内第八次熔断。机制层面已被充分记录，但值得重述：2026 年 4 月获批的三星电子、SK海力士个股 2 倍杠杆 ETF 吸引了逾 14 万亿韩元散户资金；每日重置的杠杆结构把一次半导体回调变成了自我强化的强平螺旋，7 月 13 日以来已有超过 120 万个杠杆账户触及追保线。指数较 6 月下旬 9,115 点的历史高位已回落约 39%。昨日的 -10.84% 本被当作恐慌出清的信号，今天的盘面否定了这个判断——SK海力士(000660.KS)与三星电子(005930.KS)仍被钉在跌停式卖压中，ETF 赎回与强制平仓互相喂养。一个值得注意的异常：美元/韩元下跌 2.36% 至 1,439.18（韩元走强），与央行疑似入场干预或国有机构抛售美元稳定汇率的特征相符。监管层 7 月 16 日的一揽子措施（提高现金保证金、禁用证券担保）未能止血，市场现在定价的是"数日而非数周内"出台政策响应——紧急流动性工具或临时性买方稳定基金。

日本 #

The Nikkei 225 fell 4.43% to 61,746.79, extending yesterday’s 3.95% drop, as the semiconductor equipment complex took another leg down in sympathy with Korean memory names. Tokyo Electron (8035.T) and Advantest remain the epicenter of selling — these are the most crowded foreign-held names in the AI-capex trade and thus the natural source of funds when regional portfolios are forced to raise cash. Earlier this week Kioxia’s double-digit collapses set the tone for the memory supply chain. Two cushions differentiate Japan from Korea: first, positioning was far less levered at the retail level; second, USD/JPY at 163.46 (yen still historically weak) keeps exporter earnings revisions from collapsing alongside equity prices. The macro overlay, however, is deteriorating: oil at $83.70 with the Strait of Hormuz effectively closed is a direct terms-of-trade shock for Japan, and the Ministry of Finance will be watching energy-import costs as closely as equity breadth. The Nikkei has now given back its May lows; the 60,000 psychological level is the next test.

日经 225 下跌 4.43% 至 61,746.79 点，延续昨日 3.95% 的跌势，半导体设备板块随韩国存储股再下一台阶。东京电子(8035.T)与爱德万测试仍是抛售中心——它们是 AI 资本开支交易中外资持仓最拥挤的名字，区域组合被迫筹集现金时自然成为提款机。本周早前铠侠的双位数暴跌已为存储供应链定下基调。日本与韩国有两个关键差异：其一，散户层面杠杆远低；其二，美元/日元在 163.46（日元仍处历史弱势），出口企业盈利预期不至于随股价同步崩塌。但宏观层面在恶化：霍尔木兹海峡事实性关闭、油价 83.70 美元，对日本是直接的贸易条件冲击，财务省对能源进口成本的关注度不亚于股市广度。日经已失守 5 月低点，下一个考验是 60,000 点心理关口。

香港 #

Hong Kong is trading as the relative-safety leg of the region, though the data is split across timestamps. Yesterday’s close saw the HSI up 1.96% at 25,807.92, and this morning’s snapshot shows the index essentially flat intraday (-0.03%) — remarkable resilience given the carnage in Taipei, Seoul and Tokyo. The HSCEI feed prints +3.36% at 8,633.51, pointing to state-linked buying in mainland heavyweights. Southbound flows were mixed but net positive (Shanghai leg +HK$630mn, Shenzhen leg -HK$463mn), consistent with mainland funds bottom-fishing financials and energy names while trimming tech. The logic is portfolio geography: Hong Kong’s index composition is banks, insurers, energy and China consumer — structurally short the memory/AI-capex complex that is detonating in Korea and Taiwan. The risk to this haven trade is crude: if Hormuz stays shut and WTI grinds toward $90, Hong Kong’s airline, transport and petrochemical names will start to discount the inflation pass-through.

港股正在扮演区域内的相对避险资产角色，不过数据时间戳有所错位。昨日收盘恒指涨 1.96% 报 25,807.92 点，今早快照显示盘中基本持平（-0.03%)——在台北、首尔、东京一片惨跌中表现出罕见的韧性。恒生国企指数数据流报 +3.36% 至 8,633.51 点，指向中资权重股获得类国家队资金承接。南向资金方向分化但净额为小幅流入（沪市 +6.30 亿港元、深市 -4.63 亿港元），与内地资金低吸金融、能源股同时减持科技股的结构一致。逻辑在于组合的地理属性：恒指成分以银行、保险、能源和中国消费为主，结构上天然低配正在韩国与台湾引爆的存储/AI 资本开支链条。这个避险交易的风险点是原油：若霍尔木兹持续封锁、WTI 向 90 美元磨进，香港的航空、运输和石化股将开始计价输入型通胀。

中国 #

Mainland equities opened weak but the damage is contained relative to North Asia. The morning snapshot shows the Shanghai Composite down 1.15% intraday and the Shenzhen Component down 3.79%, with breadth deeply negative (921 decliners vs 666 advancers on the Shanghai connect; 1,196 vs 638 on Shenzhen). The pressure concentrates exactly where the Korean shock transmits: A-share memory and advanced-packaging names, which had been the retail-favorite AI proxies, are being repriced on both the sentiment channel and legitimate fears that a memory price collapse in Korea bleeds into domestic contract pricing. Northbound flow prints at zero — effectively flat — suggesting foreign investors are neither fleeing nor buying the dip. Defensive rotation is visible: banks and coal are outperforming, echoing the pattern from the July 14 selloff. With the Politburo meeting window approaching and the US Section 301 “overcapacity” tariff decision (proposed 12.5% on China and 45 other economies) having just passed its July 24 effective window, domestic policy easing expectations are the main counterweight to the external shock.

A 股开盘走弱，但相对北亚市场损伤可控。早盘快照显示上证指数盘中跌 1.15%、深证成指跌 3.79%，涨跌家数明显偏空（沪股通口径 921 家下跌对 666 家上涨；深股通 1,196 家对 638 家）。压力精确集中在韩国冲击的传导点上：A 股存储与先进封装板块——此前散户最拥挤的 AI 映射标的——既受情绪面拖累，也面临韩国存储价格崩塌传导至国内合约定价的真实担忧。北向资金数据显示为零——实际持平——说明外资既没有出逃也没有抄底。防御性轮动清晰可见：银行、煤炭跑赢，复刻 7 月 14 日下跌时的结构。随着政治局会议窗口临近，且美国 301"产能过剩"关税决定（拟对中国等 46 个经济体征收 12.5%）刚跨过 7 月 24 日生效窗口，国内政策宽松预期是抵消外部冲击的主要砝码。

其他亚太市场 #

今日亚太最值得记录的并非跌幅榜，而是资金的去向。印度 SENSEX 涨 2.03%、澳洲 ASX 200 涨 1.44%、新加坡 STI 涨 1.57%——三条上涨线背后是同一个交易：从拥挤的北亚半导体杠杆仓位撤出，轮入与 AI 资本开支周期相关性低的市场。印度受益于国内资金持续流入与"非存储"的指数结构；澳洲则是能源与矿业股直接吃进霍尔木兹封锁的油价红利，WTI 站上 83 美元让资源权重占三成的 ASX 200 成为区域对冲工具。反例是泰国 SET(-1.60%）与印尼 JCI(-1.03%)：两个石油净进口国被油价与区域避险情绪双杀，东南亚内部的分化本身就是地缘定价的镜像。

资金流向 #

北向资金 #

沪股通、深股通今日净买入均录得 0.0（持平/无显著流向）。市场宽度偏空：上证侧 666 家上涨、921 家下跌，深证侧 638 家上涨、1,196 家下跌——外资观望、内资承接的格局。

南向资金 #

港股通（沪）净买入 +6.30 亿港元；港股通（深）净卖出 -4.63 亿港元，合计小幅净流入约 1.67 亿港元。方向分化对应"低吸金融能源、减持科技"的避险结构，港股通全天成交额各 420 亿港元左右，活跃度未因北亚动荡而收缩。

汇率与宏观 #

汇率端最值得玩味的是韩元：股指崩盘之日韩元反而走强 2.36%，与央行或国有机构入市卖美元的干预特征高度吻合。美债收益率下行 8bp、美元指数回落、黄金守稳 4,100 美元上方——标准的"股崩债涨"避险组合。油价在美军宣布结束新一轮对伊打击后不跌反涨，说明市场把"打击结束"读作阶段性战术暂停，而非海峡重开的前奏。

地缘冲突追踪与板块影响 #

1. 伊朗战争 / 霍尔木兹海峡 #

Latest (EN): The conflict entered its fourth week of renewed escalation. Overnight, US Central Command stated its naval blockade of Iran remains in force and has already diverted around 20 merchant vessels from Gulf routes; this morning (11:11 HKT) the US military announced the conclusion of a fresh round of large-scale strikes on Iranian targets, following Iran’s July 29 surprise attack on US bases in the region. The IRGC’s closure of the Strait of Hormuz since July 12 remains formally in place, with passage conditional on Iranian authorization. Oil has not sold off on the “strikes concluded” headline — WTI +1.32% at $83.70 — because the blockade, not the strikes, is the binding constraint on supply. Roughly 20% of global crude flows through the strait; analysts’ base case remains Brent $78–92 while the standoff persists, with $120+ in a full-closure tail.

中文： 冲突进入重启升级后的第四周。美军中央司令部隔夜表示对伊海上封锁持续生效，已迫使约 20 艘商船改变航线；今晨（11:11）美军宣布结束对伊朗的新一轮大规模打击——此前一日（7/29）伊朗刚对中东美军基地发动"突然袭击"。伊朗革命卫队自 7 月 12 日实施的海峡关闭在形式上仍然有效，通航须获伊方许可。油价对"打击结束"的消息不跌反涨（WTI +1.32% 至 83.70 美元），因为约束供给的是封锁而非空袭。全球约两成原油经霍尔木兹运输；机构基准判断仍是僵持情景下布伦特 78–92 美元区间，完全封锁的尾部情景指向 120 美元上方。

关键时间节点： 美伊谈判重启窗口（未定，市场紧盯美方"解除封锁最后期限"表态）;8 月中旬海湾夏季装载计划公布（检验海峡实际通行率）。

2. 俄乌战争 / 制裁链 #

Latest (EN): The conflict’s market impact has migrated from the battlefield to the sanctions supply chain. On July 23 the EU adopted its 21st sanctions package — targeting Russian energy, finance and the shadow fleet — which listed 14 Chinese mainland and Hong Kong entities; Beijing retaliated within 24 hours by placing 14 EU entities (including Rheinmetall and several semiconductor-materials and photonics firms) under dual-use export controls. Brussels is reportedly preparing a further, softened package. The net effect for Asia: EU defense and semiconductor-material supply chains now face Chinese input restrictions, while EU economic sanctions on Russia were extended to July 2027.

中文： 这条冲突线的市场影响已从战场转移到制裁供应链。7 月 23 日欧盟通过对俄第 21 轮制裁（覆盖能源、金融与影子舰队），将 14 家中资实体列入清单；中方 24 小时内对等反制，将莱茵金属等 14 家欧盟军工、半导体材料与光电实体纳入两用物项出口管制。欧盟据悉正酝酿新一轮、但条款明显弱化的方案；对俄经济制裁期限已延长至 2027 年 7 月。对亚洲的含义：欧洲军工与半导体材料供应链开始承受中国原料管制，稀土、磁材与靶材的出口许可成为新摩擦点。

关键时间节点： 欧盟第 22 轮制裁表决（预计 8 月）；中欧就两用物项管制的后续交涉。

3. 全球关税 / 贸易冲突 #

Latest (EN): The Section 122 global 10% surcharge expired on July 24, and the USTR’s Section 301 “manufacturing overcapacity” investigation — covering 16 economies — has entered its decision window, with a proposed 12.5% tariff on China, Hong Kong and 44 other economies. Front-loading ahead of the switch pushed China–US freight rates to two-year highs. Separately, the June-announced semiconductor tariff escalation ladder (new rates effective 2027) keeps a structural overhang on the Asian chip complex — one more reason the Korea/Taiwan selloff is finding no policy floor from trade relief.

中文： 第 122 条款 10% 全球临时附加税已于 7 月 24 日到期，USTR 覆盖 16 个经济体的 301"产能过剩"调查进入决定窗口，拟对中国大陆、香港等 46 个经济体加征 12.5% 关税。企业赶在切换窗口前抢运，把中美航线运价推至两年高位。另外，6 月预告的半导体关税阶梯（2027 年生效）持续压制亚洲芯片链的远期估值——这也是本轮韩台抛售缺少贸易面缓冲的原因之一。

关键时间节点： 301 调查最终决定公布（随时可能落地）;11 月中美贸易休战安排到期。

4. 韩国杠杆危机（金融稳定事件） #

虽非军事冲突，但已是当前亚洲市场最大的单一风险源：KOSPI 较 6 月高点回撤约 39%，年内八次熔断并首次触发 -20% 休市线；逾 120 万杠杆账户触及追保，散户保证金存款较 6 月底蒸发近 30 万亿韩元。监管层 7 月 16 日的去杠杆组合拳未能止血，市场等待更高级别的流动性响应。

关键时间节点： 韩国监管层紧急会议（市场预期数日内）;SK海力士二季度正式财报（验证 60.4 万亿韩元营业利润预测）;8 月韩国央行议息——加息周期是否因金融稳定而急转弯。

专家研判 #

相对受益方向：

1. 上游油气——中海油(0883.HK)、Woodside(WDS.AU)：海峡封锁的风险溢价直接兑现；
2. 黄金与贵金属——山东黄金(600547)、紫金矿业(601899)：避险 + 实际利率回落双驱动；
3. 油运集运——中远海能(600026)、中远海控(601919)：绕行 + 抢运，运价两年高位；
4. 印度/澳洲指数资产——SENSEX、ASX 200：北亚去杠杆的资金承接地；
5. 中国国产半导体替代——中芯国际(0981.HK)、北方华创(002371)：关税与韩系动荡共同强化份额逻辑。

需要回避方向：

1. 韩国半导体及 2 倍个股杠杆 ETF——强平螺旋未见底，波动率未系统性收敛前不接飞刀；
2. 日本半导体设备——东京电子(8035.T)、爱德万测试(6857.T)：外资拥挤持仓的提款机；
3. 航空与石化下游——国泰(0293.HK)、恒力石化(600346)：油价冲击的成本端；
4. 泰国、印尼等石油净进口国资产——油价与避险情绪双杀，SET 已率先走弱。

情景分析（未来 2 周，以美伊僵局演化为主轴）:

• 情景 A：战术暂停、谈判重启（概率约 40%)——海峡部分恢复通航，WTI 回落至 75–78 美元；北亚出现报复性反弹，但韩国去杠杆仍需时间，反弹幅度韩 < 台 < 日。
• 情景 B：封锁僵持、零星交火（概率约 45%，基准情形）——油价 83–92 美元高位震荡；能源与避险资产继续跑赢，韩股在监管救市与强平残余之间反复磨底，市场宽度持续恶化。
• 情景 C：海峡完全关闭 / 曼德海峡受累（概率约 15%)——布伦特冲击 120 美元上方，全球滞胀交易启动；亚洲股市无差别下挫，唯黄金、油气、油运独善。
