Mass Foreign Withdrawal from Emerging Markets: $17 Billion Weekly Outflow

Overview

This Goldman Sachs weekly fund flow monitoring report focuses on capital dynamics across emerging markets for the week ended May 15, 2026. Its central finding is that Asia ex-China emerging markets experienced the second-largest weekly foreign institutional investor (FII) outflow on record—approximately $17 billion. South Korea was the largest source of this outflow, with $13.2 billion in net foreign selling during the week. In sharp contrast, domestic South Korean retail investors aggressively entered the market, purchasing $14.1 billion net during the same period. The report also details global equity fund flows, institutional investor (DII) activity, and forecasts the impact of the upcoming MSCI index rebalancing at the end of May—projected to generate over $76 billion in two-way fund flows.

Core views

**Record Foreign Outflows, with South Korea as Primary Source of Selling Pressure** For the week ended May 15, foreign institutional investors (FIIs) withdrew approximately $17 billion from Asia ex-China emerging markets—the second-largest weekly outflow on record, surpassed only by a week in early March 2026. Although FIIs had net purchased $19 billion since the April 2025 low, they have since cumulatively net sold $29 billion. South Korea was the dominant contributor to this outflow, with $13.2 billion in net foreign selling; Taiwan (-$2.5 billion) and India (-$1.3 billion) also registered notable outflows. **Retail Capital Provides Significant Offsetting Support** Across Asian markets, South Korean retail investors bought $14.1 billion net this week—substantially offsetting foreign outflows and contributing to South Korea’s year-to-date (YTD) retail net purchases of $26.2 billion. By contrast, Taiwanese retail investors modestly net sold $800 million. Overall, Asian markets recorded $27 billion in YTD retail net inflows. **Global and Emerging Market Fund Flow Landscape** Global equity funds recorded $21 billion in net inflows this week—well above last week’s $3 billion. Among developed markets, U.S. equity funds attracted $21.9 billion in net inflows, Japanese equity funds saw $4.6 billion in net inflows, while European equity funds experienced $1.5 billion in net outflows. Global emerging market (GEM) equity funds posted $2.6 billion in net outflows this week—still higher than prior levels. Regionally, China-focused funds were the main drag, while Taiwan-focused funds were a bright spot for inflows. **MSCI Index Rebalancing: Expected to Trigger Large-Scale Portfolio Turnover** The report emphasizes that the MSCI index rebalancing—effective after market close on May 29—is projected to drive over $76 billion in total two-way trading volume across Asia-Pacific markets. On a net basis, Taiwan, South Korea, South Africa, and Saudi Arabia are expected to receive the largest passive fund inflows; conversely, India, China, Indonesia, Mexico, and Turkey may face outflows. At the sector level, technology hardware and semiconductors, as well as metals and mining, are projected to attract the largest passive fund inflows.

Analysis framework

This report adopts a **fund flow tracking and analysis methodology**, primarily using high-frequency (weekly) data on capital movements by foreign institutional investors (FII), domestic institutional investors (DII), and retail investors to monitor capital flows into emerging markets. Its core analytical logic is: 1. **First Layer: Macroeconomic Fund Flow Monitoring**: Focuses first on the aggregate FII outflow from EM Asia ex-China, directly highlighting its historically anomalous scale. 2. **Second Layer: Country- and Regional-Level Decomposition**: Breaks down total outflows by major economies (e.g., South Korea, Taiwan, India), comparing both magnitude and timing to identify the dominant drivers. 3. **Third Layer: Investor-Type Comparison**: Contrasts foreign outflows against domestic retail inflows to reveal intra-market capital dynamics and offsetting forces. 4. **Fourth Layer: Mainstream Fund Tracking**: Uses EPFR and similar data sources to analyze subscription/redemption patterns across global equity funds (GEM, U.S., Europe, Japan, etc.) and regional funds—providing context for broader global capital allocation trends. 5. **Fifth Layer: Event-Driven Analysis**: Finally, integrates the imminent MSCI index rebalancing to quantify the anticipated passive fund-driven trading volumes (inflows/outflows)—a highly predictable near-term driver of fund flows. Overall, the report employs a **top-down framework (macro → country → investor type → event-driven)**, supported by extensive data charts (numerous Exhibit references cited in-text) to substantiate its conclusions.

Methodology notes

• Industry/sector analysis frameworkSupply-demand framework

  Supply-demand analysis of emerging market fund flows

  The report treats capital as a commodity, analyzing the relative strength of supply-side forces (e.g., foreign selling, fund redemptions) versus demand-side forces (e.g., domestic retail buying, passive fund inflows) to assess short-term market funding pressure. For example, South Korea’s massive foreign selling (supply) is partially offset by strong domestic retail buying (demand), thereby mitigating the absolute impact of net selling pressure.

• Event-driven analysis & behavioral financeEvent-driven analysis

  Quantifying the impact of MSCI index rebalancing on passive fund flows

  This method forecasts how much passive index-tracking funds must buy or sell when a stock or market is added to or removed from a major index. The report estimates that the end-of-May MSCI rebalancing will trigger over $76 billion in trading volume—calculated by multiplying changes in constituent market-cap weights by the assets under management (AUM) of funds tracking the index—making it the most certain near-term driver of fund flows.

• Finance industry-specific terminologyNet Interest Margin (NIM) Analysis

  Analysis of net effect of fund flows (Net vs Gross)

  The report emphasizes net flows—not just gross volumes. For instance, although the MSCI rebalancing is estimated to generate $76 billion in gross trading, the net market-level impact is projected to be minimal (-$400 million), meaning that while individual stocks may experience sharp price swings, broad market-level capital positions remain largely unchanged. This highlights a key insight: gross totals overstate impact; distinguishing gross from net flows is essential.

Impact & implications

The data presented indicate that emerging markets—especially Asia ex-China—are undergoing rapid foreign capital withdrawal, exerting significant short-term pressure on market liquidity and equity valuations. However, the report also reveals internal divergence: South Korea exhibits both the largest outflow and the largest offsetting inflow, rendering its risk relatively contained; in contrast, markets such as Taiwan and India face foreign outflows without commensurate domestic counterbalancing, implying greater vulnerability. The robust inflows into developed-market funds—versus outflows from emerging markets—suggest capital reallocation rather than systemic withdrawal. The MSCI rebalancing will likely amplify stock-level volatility, particularly for illiquid names or those with high passive-fund ownership.

Risks

• Sustained, larger-than-expected foreign outflows triggering liquidity crises in select markets (e.g., South Korea, Taiwan)
• Declining domestic retail buying momentum, undermining its ability to continue offsetting foreign selling
• A sharp deterioration in global risk sentiment prompting further withdrawals from emerging markets by global funds
• Post-MSCI-rebalancing, stocks sold passively facing sharp near-term price declines
• Geopolitical uncertainties (e.g., involving South Korea or Taiwan) exacerbating the persistence of foreign outflows

What to watch

• Monitor whether foreign outflows moderate or accelerate in coming weeks to assess whether a trend inflection point has formed
• Track actual fund flows and price reactions across markets and individual stocks following the May 29 MSCI rebalancing
• Assess sustainability of South Korean retail buying—this will determine the market impact of foreign outflows
• Monitor subscription/redemption data for GEM and regional funds to gauge evolving global investor appetite for emerging markets
