FTSE GEIS June 2026 rebalancing is expected to generate significant passive flows in Asia-Pacific and Emerging Markets
Goldman Sachs estimates that the June rebalancing of the FTSE Global Equity Index Series will trigger about US$34bn of two-way trading flows in Asia-Pacific and about US$23bn in Emerging Markets, resulting in net passive inflows of about US$4.1bn for Asia-Pacific and about US$0.9bn for Emerging Markets.
- FTSE Russell announced the final revision results for the Global Equity Index Series after the close on June 5, 2026, with implementation after the close on June 19; Mainland China, Hong Kong, China, and Taiwan, China will implement earlier after the close on June 18 due to holidays.
- In the FTSE Developed/Emerging All World Index large- and mid-cap universe, there are 2/15 additions and 3/2 deletions, respectively; in the All Cap universe, there are 10/17 additions and 7/6 deletions, respectively.
- The report estimates the pro forma market capitalization of the FTSE Developed All Cap ex-US Index at about US$31.7tn and the FTSE EM All Cap Index at about US$11.7tn, with index weight adjustment magnitudes of about 0.9% and 0.8%, respectively.
- Within Asia-Pacific markets, Japan is expected to see net inflows of about US$2.4bn, while Mainland China/Hong Kong, China are expected to see net inflows of about US$1.2bn; Indonesia and Thailand may face selling pressure of about US$400mn and US$300mn, respectively.
- At the sector level, technology hardware and semiconductors, capital goods, chemicals and other materials, and banks are expected to receive larger passive inflows; energy, autos, consumer staples, and transportation are expected to face larger outflows.
Report interpretation
Overview
This report tracks FTSE Russell's final revision results for the June 2026 rebalancing of the Global Equity Index Series, China Index Series, and Taiwan Index Series, and assesses their potential impact on index weights, regional markets, sectors, and stock-level passive fund flows. The report notes that the June quarterly review is typically a modest adjustment period for FTSE GEIS, mainly reflecting corporate actions such as IPOs, spin-offs, changes in shares outstanding, and changes in free float.
Core views
The core view is that although this FTSE rebalancing is only a small quarterly adjustment, it could still bring sizable two-way passive trading flows to Asia-Pacific and Emerging Markets; in net terms, Asia-Pacific and Emerging Markets are expected to see overall net inflows, with Japan and Mainland China/Hong Kong, China as the main beneficiary markets, while Indonesia and Thailand are relatively under pressure. At the sector level, technology hardware and semiconductors, capital goods, chemicals and other materials, and banks may see the largest inflows, while energy, autos, consumer staples, and transportation may see the largest outflows. Historical experience shows that FTSE GEIS additions have typically underperformed deletions after the announcement of the preliminary results, but may still modestly outperform later, though with a more volatile path.
Analysis framework
The report uses an index rebalancing event analysis framework, mapping the constituents and weight changes finally announced by FTSE Russell to pro forma index market capitalization, weight adjustments, passive fund tracking scale, and potential trading demand. Fund flow estimates combine EPFR and FactSet Ownership data, covering global funds tracking broad FTSE market benchmarks as well as local market funds; liquidity screening at the stock level uses relative ADVT thresholds together with free float factor estimates.
Methodology notes
Estimate additions, deletions, weight changes, and implementation-day trading demand based on FTSE Russell's final review results.
The report focuses on the final results for the FTSE GEIS, China, and Taiwan index series, compares current and pro forma index composition, and estimates the buying and selling demand that passive funds may generate to track the new weights.
Derive passive buying and selling amounts caused by rebalancing from the asset size of funds tracking the relevant indices.
Potential passive fund flow estimates consider global funds tracking broad FTSE market benchmarks and local market funds, with data sources including EPFR and FactSet Ownership.
Measure stock-level trading impact using potential fund flows relative to average daily trading volume.
The report highlights stocks expected to see large net passive buying or selling and that meet a threshold relative to ADVT, in order to identify names that may face more visible trading pressure.
Use free float factors to estimate changes in investable index weights.
Free float factors are compiled based on the average of estimates from Bloomberg, FactSet, and Refinitiv, with pricing benchmarked to June 5, 2026.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- FTSE Developed All Cap ex-US IndexRebalancing target for developed market equity index
- Strengths
- Pro forma index market capitalization is about US$31.7tn, with relatively moderate adjustment magnitude, mainly reflecting small quarterly changes and corporate actions.
- Weaknesses
- Weight adjustments may still lead to localized trading crowding during the implementation window.
- Comparison
- Compared with the FTSE EM All Cap, it has a larger market capitalization scale but lower pro forma market capitalization growth.
- Risks
- Passive flow estimates depend on tracked asset scale, free float factors, and prices before the implementation date.
- FTSE EM All Cap IndexRebalancing target for emerging market equity index
- Strengths
- Pro forma index market capitalization is about US$11.7tn, with expected net passive inflows and coverage across multiple regional markets.
- Weaknesses
- Liquidity and trading impact vary widely across Emerging Markets, and some local markets may face heavier selling pressure.
- Comparison
- Compared with the developed market universe, both the pro forma market capitalization increase and the number of additions are more notable.
- Risks
- Holidays, liquidity, tracking error, and fund execution timing may cause actual fund flows to deviate from estimates.
- Asia-Pacific equity marketsRegion mainly affected by fund flows
- Strengths
- Expected net passive inflows are about US$4.1bn, with Japan and Mainland China/Hong Kong, China contributing the main positive inflows.
- Weaknesses
- Indonesia and Thailand are expected to see net outflows, and some markets may come under pressure around the implementation date.
- Comparison
- Asia-Pacific is expected to see gross two-way trading flows above US$34bn, higher than the US$23bn scale shown for Emerging Markets in the report.
- Risks
- Actual trading flows are affected by fund tracking benchmarks, execution timing, market liquidity, and exchange-rate volatility.
- Technology hardware and semiconductors, capital goods, chemicals and other materials, banksSectors expected to receive larger passive inflows
- Strengths
- Each sector is expected to receive about US$500mn to US$1,600mn of passive inflows, which may support short-term trading demand.
- Weaknesses
- The flow-driven support is relatively short term and does not necessarily indicate improved sector fundamentals.
- Comparison
- Compared with energy, autos, consumer staples, and transportation, these sectors have a more favorable flow direction in this rebalancing.
- Risks
- If newly added or upweighted names lack sufficient liquidity, price volatility may intensify around the implementation date.
- Energy, autos, consumer staples, transportationSectors expected to bear larger passive outflows
- Strengths
- The flow impact provides a window to observe sector repricing and liquidity absorption capacity.
- Weaknesses
- Each sector is expected to see passive outflows of about -US$100mn to -US$350mn, which may create short-term selling pressure.
- Comparison
- Compared with the inflow sectors, passive allocation changes are less favorable for these sectors in this rebalancing.
- Risks
- If market liquidity is weak, selling pressure may be amplified; if active capital absorbs the flows strongly, actual price impact may be smaller than the estimated fund flows.

Impact & implications
The main investment implication of this rebalancing lies in short-term trading flows and relative performance rather than changes in fundamental ratings. Passive funds need to adjust holdings around the implementation window, which may amplify trading volume and price volatility for additions, deletions, and stocks with large weight changes. For regional allocation, Japan and Mainland China/Hong Kong, China benefit from net inflow support, while Indonesia and Thailand face relative selling pressure; for sector allocation, technology hardware and semiconductors, capital goods, chemicals and other materials, and banks benefit from increased passive allocation, while energy, autos, consumer staples, and transportation are relatively under pressure.
Risks
- Fund flow estimates are based on data such as EPFR, FactSet Ownership, prices, and free float factors, and actual passive fund tracking scale and execution methods may differ.
- Trading crowding, pre-positioning, or arbitrage may occur around the rebalancing implementation date, causing price action to differ from historical patterns.
- The implementation dates for Mainland China, Hong Kong, China, and Taiwan, China differ from those of other markets, which may create differences in cross-market execution timing.
- The report is an index strategy event analysis and does not constitute a standalone investment recommendation or fundamental rating on any single stock.
- Historically, the performance path of additions relative to deletions has been highly volatile, and historical patterns cannot guarantee future performance.
What to watch
- Actual trading volume, closing prices, and fund flow execution during the rebalancing implementation window after the close from June 18 to June 19, 2026.
- Whether Japan and Mainland China/Hong Kong, China receive the largest net passive inflows as estimated.
- Whether the Indonesian and Thai markets experience short-term performance pressure consistent with the expected selling pressure.
- Relative performance of inflow sectors such as technology hardware and semiconductors, capital goods, chemicals and other materials, and banks.
- Liquidity absorption in outflow sectors such as energy, autos, consumer staples, and transportation around the implementation date.
- Whether the relative performance of FTSE GEIS additions versus deletions from the final results announcement through post-implementation follows historical patterns.
