Why Foreign Investors Pulled a Record $137 Billion From Asian Stocks in H1 2026

In the first half of 2026, foreign investors sold Asian equities at the fastest pace in at least 16 years, pulling a net $137.36 billion from markets in South Korea, Taiwan, India, Indonesia, Thailand, Vietnam, and the Philippines . The outflow—the highest half-year total on record—was not a single event but a cascade of mutually reinforcing pressures: a crowded AI trade that had to be unwound, an oil shock from the escalating US-Iran war, a disappointing earnings report from Broadcom, and a hawkish repricing of global interest rates that made Asian equities less attractive. The result has been a sharp concentration of foreign capital into a handful of AI-chip giants, creating risks that even BlackRock has now flagged as a reason to downgrade emerging markets .

What Caused the Record $137 Billion Outflow?

The data from regional stock exchanges and LSEG show the outflow built steadily over the first half of 2026, driven by four main forces:

AI-driven crowding and profit-taking. A blistering rally in AI-linked tech stocks, especially in South Korea and Taiwan, pushed valuations to levels that forced institutional investors to trim their biggest winners and rebalance. Analysts called it a "crowded trade" unwind . In South Korea alone, Samsung Electronics and SK Hynix surged roughly 225% year-to-date, likely breaching single-stock exposure limits at many global funds, according to UBS .

Middle East conflict and oil shock. The escalating US-Israeli war with Iran triggered a severe oil price spike, which reset risk models across global portfolios. Net oil-importing Asian economies were hit particularly hard . By March, foreign investors had already pulled $70.3 billion from emerging-market assets in the largest monthly outflow since the pandemic rout of March 2020, with Asian equities accounting for the bulk .

Tech rout after Broadcom earnings. Disappointing earnings from Broadcom in June triggered a broader decline in AI-related technology shares, accelerating the exits . The selloff in June alone reached $27.08 billion, surpassing the total net outflow of $24.08 billion recorded in May .

Rising global bond yields and inflation fears. Conflict-driven inflation forced a re-evaluation of interest rate forecasts, making Asian equities less attractive relative to fixed income . By late May, the 30-year US Treasury yield spiked, and investors withdrew $17.27 billion from regional equities in a single week .

Stagnant earnings in some markets. In India specifically, lackluster earnings growth, weak rupee, and limited direct AI investment opportunities drove selling. By end-April, Indian outflows had already surpassed the full-year 2025 total .

Which Countries Were Hit Hardest?

The selling was concentrated in the three largest AI-chip-linked markets. As of June 12, total outflows from these three markets had already reached ~$134 billion before hitting $137 billion by end-June .

• South Korea suffered the most severe outflow, estimated between $70 billion and $78 billion in the first half—more than three times the $20-something billion seen during the pandemic peak of H1 2020 . The KOSPI delivered its strongest first-half performance since 1999, yet foreign money fled because the rally had become too concentrated in Samsung and SK Hynix .
• India recorded the second-largest selling in Asia, with approximately $31 billion of outflows by June 12 . Foreign portfolio investors (FPIs) dumped Indian equities worth over ₹1.8 lakh crore in the first four months alone, surpassing the total for all of 2025 .
• Taiwan saw roughly $22 billion of outflows by June 12, driven by the AI chip rout and TSMC concentration concerns . In March alone, Taiwan experienced the most significant capital outflow in the region, amounting to $25 billion .

How Did Global Banks and Central Banks Respond?

The crisis forced central banks across Asia into a sharp policy rethink. The Iran oil shock drove up inflation expectations, limiting central banks' ability to cut rates. South Korea signaled it could adopt a more hawkish stance if inflation exceeded targets; the Bank of Japan found itself less able to pause rate hikes as oil prices added inflationary pressure; and the IMF encouraged policymakers to consider unconventional strategies to manage capital flight .

The Institute of International Finance (IIF) reported that in March, non-resident investors withdrew $70.3 billion from emerging-market assets—the largest outflow since March 2020—with equity outflows of $56 billion being the largest such loss in at least 20 years . The IIF noted that equity allocations tend to react more swiftly to significant geopolitical disturbances that threaten growth.

Investment banks flagged concentration risks. HSBC noted that TSMC had become the most underweighted stock in Asia-focused portfolios, underscoring how the AI chip rally had distorted normal stock-picking . As one fund manager told Reuters, "As equities continue to excel, funds will face increasing difficulty in adding exposure, perpetuating persistent selling pressure" .

How Did BlackRock Respond?

BlackRock, the world's largest asset manager, sent a mixed signal that reflected the complexity of the situation. In mid-June, BlackRock publicly stated that India's equity market had been "over-punished" by the AI-driven rotation and oil shock, and that the country's medium- to long-term investment case remained intact. Natasha Sarkaria, BlackRock's EMEA wealth investment strategy lead, affirmed the firm remained constructively positioned on India, citing demographics, infrastructure, and financials .

But by the end of June, BlackRock shifted course. In its 2026 mid-year global investment outlook, the BlackRock Investment Institute downgraded emerging-market equities from overweight to neutral for the next six to 12 months, explicitly citing concentration risk in AI-linked companies as the reason . The downgrade targeted markets including Taiwan and South Korea that have heavy exposure to AI-related firms. This was a notable reversal from BlackRock's own Spring Investment Directions report, which had been constructive on EM, stating "we prefer emerging over developed market equities, given the centrality of many EM countries in the ongoing AI buildout" .

What Risks Does AI-Chip Stock Concentration Pose to Emerging Markets?

The concentration of foreign capital in AI-chip stocks has become extreme. Three companies—TSMC, Samsung, and SK Hynix—now account for nearly one-third of the MSCI Asia Pacific ex-Japan index . This creates several risks:

Systemic vulnerability to a single sector trigger. If AI capex expectations falter or chip earnings disappoint again (as with Broadcom in June), a further rout in these three stocks would disproportionately drag down the entire Asian index . BlackRock's mid-year outlook explicitly cited this risk as a reason for its downgrade .

Distorted portfolio construction and forced selling. Active fund managers are already deeply underweight TSMC relative to its index weight. HSBC called TSMC the most underweighted stock in Asian portfolios . This dynamic creates a perverse feedback loop: any further rally in AI chips forces constant rebalancing selling, while any downturn forces passive funds to sell other holdings to meet redemptions.

Reduced diversification for emerging markets. With foreign capital fleeing non-AI markets like India and rotating into a narrow set of AI-chip names, emerging markets as an asset class become less diversified and more correlated with US tech sentiment . Markets like India have been sold down disproportionately, creating valuation opportunities but also leaving them starved of foreign capital at a time when higher oil prices and weaker currencies compound the pressure .
