2026-10-02 MSCI China v2026.02 → v2026.08 M4 Selection and constituent count Minor The updated text removes the specific provision excluding Indian securities on the NSDL/CDSL official list when the Red flag or Breach limit has been reached, while retaining the general exclusion for securities subject to foreign-ownership purchase restrictions. It also replaces “MSCI Global Investable Market Indexes” and “Investable Market Index” with “GIMI™” and “IMI™/IMI,” respectively, and moves the size-segment derivation paragraph without changing that rule.

2026-10-02 MSCI China v2026.02 → v2026.08 M9 Calculation and return variants Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M9 Calculation and return variants Editorial The footnote/reference numbers in this section are shifted by one (53–55 become 54–56). The fragmentary closing note is also changed from “Non-current IMI constituent” to “Non-current IMIT constituent.” The operative market-closure and suspended-security review rules are unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M9 Calculation and return variants Editorial The updated section makes no substantive change to the trading-suspension policy. It adds the ™ symbol to IMI and renumbers the associated footnote references from 53–55 to 54–56, including a minor spacing adjustment before a footnote marker.
2026-10-02 MSCI China v2026.02 → v2026.08 M3 Eligibility screens Minor The minimum foreign-room requirement itself is unchanged at 15%, but the updated section adds an India-specific eligibility restriction: securities on the NSDL/CDSL official list for which the Red flag or Breach limit has been reached would not be considered. In the supplied text, the inserted sentence is spliced directly into the following sentence beginning with “For a security.”
2026-10-02 MSCI China v2026.02 → v2026.08 M3 Eligibility screens Editorial The section was reworded to use the abbreviated trademarked terms "IMI™" and "GIMI™" instead of "Investable Market Indexes" and "GIMI." The liquidity thresholds, alternative-listing priority, Emerging Markets retention condition, and Liquidity Adjustment Factor rules were unchanged; footnotes were renumbered from 50–52 to 51–53.
2026-10-02 MSCI China v2026.02 → v2026.08 M4 Selection and constituent count Minor The light-rebalancing addition rule narrows the exclusion for securities with extreme price increases. Under the updated methodology, such securities are ineligible only when their FIF is less than 0.75, whereas the previous text excluded all securities exhibiting extreme price increases. The abbreviation of "Investable Market Indexes" to "IMI™," footnote renumbering, and sentence relocation are formatting changes.
2026-10-02 MSCI China v2026.02 → v2026.08 M7 Buffers and turnover control Major The light-rebalancing rule for Small Cap-to-Standard migration after an extreme price increase has been narrowed: the updated text makes ineligibility conditional on having a FIF below 0.75, whereas the previous text applied the bar to all existing IMI constituents exhibiting an extreme price increase. The explicit statement that such migrants would be retained as Small Cap constituents was removed and replaced by a cross-reference to the detailed treatment. Other edits are IMI naming/trademark changes, formatting, and footnote renumbering.
2026-10-02 MSCI China v2026.02 → v2026.08 M6 Review and rebalance schedule Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M6 Review and rebalance schedule Editorial The substantive communication-date and light-rebalancing policy is unchanged. The only update renumbers the two footnotes at the end of the section from 46 and 47 to 47 and 48.
2026-10-02 MSCI China v2026.02 → v2026.08 M6 Review and rebalance schedule Editorial Editorial change: wording only, no rule changed.

2026-10-02 MSCI China v2026.02 → v2026.08 M5 Weighting and capping Minor The FIF methodology for depository receipts whose underlying shares are not available for trading is replaced beginning with the May 2026 Index Review. New additions will use the lower of (i) the higher of adjusted 13F ownership or capital-raising float and (ii) free float under the current MSCI Free Float Data Methodology. Existing constituents will transition in phases, with a midpoint adjustment in May 2026 and full application of the new approach from November 2026 if enhanced transparency remains unavailable.

2026-10-02 MSCI China v2026.02 → v2026.08 M5 Weighting and capping Editorial The core free-float-adjusted market capitalization formula is unchanged, but the illustrative tables are revised. The non-FOL example adds a third company and changes sample FIFs and adjusted capitalizations; the FOL example now uses two companies, a "Rounded Free Float" line and 33.33% foreign ownership limits, while omitting the prior foreign-strategic-adjustment rows and the special footnote.
2026-10-02 MSCI China v2026.02 → v2026.08 M5 Weighting and capping Minor The FIF methodology replaces the prior >15% / <15% split with three free-float bands: >25%, 5–25%, and <5%. Rounding changes to 2.5%, 0.5%, and 0.1% respectively, with the upper band now rounded to the nearest increment rather than rounded up, and FOLs are rounded to 0.1%. For securities with a LIF, both adjusted free float and FOL are now rounded to 0.1%, replacing the prior tiered 5%/1% treatment.
2026-10-02 MSCI China v2026.02 → v2026.08 M5 Weighting and capping Minor For securities subject to foreign ownership limits, the methodology no longer adjusts the FOL downward for foreign non-free-float shareholdings. The foreign-investor free float is now the lower of the estimated free float and the unadjusted FOL, and the prior applicability note for countries where foreign room is not monitored was removed.

2026-10-02 MSCI China v2026.02 → v2026.08 M3 Eligibility screens Editorial The illustrative example of the two-Index-Review lag is rolled forward from February/August 2026 to August 2026/February 2027. The reported review result is updated from no additional markets qualifying in February 2026 to no additional markets qualifying in August 2026. Index names are also abbreviated with GIMI™/IMI™ trademarks; the eligibility thresholds, Frontier Markets exception, two-review lag, and country list are unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M2 Universe Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M4 Selection and constituent count Minor The list of markets subject to minimum-constituent index continuity rules has been updated from the February 2026 Index Review to the August 2026 Index Review. Within the affected frontier markets, Hungary is replaced by Peru; New Zealand and Egypt remain listed for developed and emerging markets, respectively.
2026-10-02 MSCI China v2026.02 → v2026.08 M1 Identity, objective, classification Minor The update increases the full and float market-cap thresholds used in the market classification Size and Liquidity Requirements for Frontier, Emerging, and Developed Markets, in both entry and maintenance requirements. It also updates the World Bank high-income GNI reference from USD 13,935 in 2024 to USD 14,375 in 2025, and changes the stated minimum-in-use review from February 2026 to August 2026. ATVR requirements, company counts, and market accessibility criteria are unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M3 Eligibility screens Minor The disclosed Equity Universe Minimum Size Requirement was updated from the February 2026 Index Review level to the August 2026 level. The minimum full market capitalization rose from USD 507 million to USD 585 million for Developed and Emerging Markets, and from USD 13 million to USD 14 million for Frontier Markets.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Major The surveillance-board lookback period for India ASM, Korea Investment Alert/Investment Risk, and Taiwan Disposition Board securities now starts at the current Index Review Price Cutoff Date rather than the previous one. Indonesia Watchlist Board Criteria 10 is separately retained under the previous cutoff date. The affected securities remain ineligible for IMI additions and Standard/Small Cap size-segment migrations at that review and are re-evaluated at the next review.

2026-10-02 MSCI China v2026.02 → v2026.08 M2 Universe Minor The updated Emerging Markets eligible-markets table adds "Taiwan Innovation Board" to the Taiwan market segments. The other differences are primarily line-break and table-layout reformatting.
2026-10-02 MSCI China v2026.02 → v2026.08 M2 Universe Minor The developed-markets eligible exchange table adds Texas Stock Exchange under the USA, marked with footnote (6). The new footnote states that listings on this exchange are eligible for the MSCI Indexes from July 06, 2026. Other table changes appear to be formatting or line-break adjustments.

2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Major The updated methodology adds an exception to the existing five-business-day deadline for amending Index Review changes. If new information emerges after that deadline but before the Index Review effective date, MSCI may make amendments on shorter notice to minimize turnover or avoid replicability issues.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Major The updated section abbreviates the index name to MSCI GIMI™ and adds footnote 33. The new footnote establishes a special minimum float-adjusted market capitalization requirement when a Standard Index constituent has a post-event FIF below 0.15, equal to two-thirds of 1.8 times one-half of the Standard Index Interim Size-Segment Cutoff.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Major The updated section renames MSCI Global Investable Market Indexes as “MSCI GIMI™” and inserts a line break, which are presentational changes. More importantly, it deletes former footnote 33 stating a minimum float-adjusted market capitalization requirement for Standard Index constituents with a post-event FIF below 0.15. No effective date for the change is stated in the text.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M4 Selection and constituent count Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Editorial The revised section replaces the spelled-out Global Investable Market Indexes and Investable Market Index terminology with GIMI™ and IMI™, and it adjusts paragraph/table formatting. The 50% increase and 33% decrease triggers, FIF and float-adjusted capitalization conditions, size-segment migration rules, and deletion criteria remain unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Editorial The methodology title is abbreviated from “MSCI Global Investable Market Indexes Methodology” to “MSCI GIMI™ Methodology” (and subsequently “MSCI GIMI Methodology”). The text also removes a footnote/cross-reference artifact (“30 As described in section 3.2.7”), restoring the sentence to “When subsequent public disclosure…”. No implementation thresholds, timing, deletion rules, or NOS/FIF treatment changes.
2026-10-02 MSCI China v2026.02 → v2026.08 M8 Corporate actions, IPOs, ad-hoc changes Editorial The updated text replaces "Investable Market Indexes" with the abbreviated trademark form "IMI™ Indexes," adds a space before footnote marker 30, and includes the footnote reference directing readers to section 3.2.7 for significant IPOs. The methodology for calculating and applying Interim Market Size-Segment Cutoffs is unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M6 Review and rebalance schedule Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M5 Weighting and capping Minor The FIF review replaces the prior single free-float change threshold of more than 1% for existing constituents with tiered thresholds based on the security’s free float: at least 2.5% for free float above 25%, 0.5% for free float from 5% to 25%, and 0.1% for free float below 5%. The exceptions to these thresholds are also revised to cover size-segment migrations, deletions from the IMI in connection with Micro Cap additions, and FOL-driven FIF changes, while retaining corrections.
2026-10-02 MSCI China v2026.02 → v2026.08 M3 Eligibility screens Minor A new rule excludes existing IMI constituents with an extreme price increase and FIF below 0.75 from migration into the Standard Indexes. Their treatment depends on 1.8x market-capitalization cutoff tests: smaller constituents remain Small Caps, while larger constituents are deleted from the Small Cap Index, retained in the investable universe, and reconsidered at the next Index Review.
2026-10-02 MSCI China v2026.02 → v2026.08 M5 Weighting and capping Editorial The section was renumbered and retitled as the minimum foreign-room requirement, with the general existing-constituent free-float buffer and extreme-price-increase paragraphs removed from this section as part of the split. The foreign-room adjustment factor, quarterly review, 12-month upward-adjustment waiting period, and related monitoring rules remain substantively unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M7 Buffers and turnover control Editorial Editorial change: wording only, no rule changed.
2026-10-02 MSCI China v2026.02 → v2026.08 M3 Eligibility screens Major The updated text adds a provision stating that at “light” rebalancings, size-segment buffer zones are set at one half of and 1.8 times the Market Size-Segment Cutoff. The surrounding investability-requirements sentence is unchanged but split by the inserted footnote.
2026-10-02 MSCI China v2026.02 → v2026.08 M7 Buffers and turnover control Major The update removes the footnote specifying different buffer-zone boundaries at “light” rebalancings: one half of and 1.8 times the Market Size-Segment Cutoff. The remaining changes are terminology, trademark, hyphenation, and footnote-placement edits and do not alter the standard 2/3 and 1.5 times buffer boundaries.
2026-10-02 MSCI China v2026.02 → v2026.08 M1 Identity, objective, classification Editorial Editorial change: wording only, no rule changed.

2026-10-02 MSCI China v2026.02 → v2026.08 M4 Selection and constituent count Minor The updated section adds footnote 20 defining the Interim Market Size-Segment Cutoff during an Index Review. It must use post-review Number of Shares and Foreign Inclusion factor, is not limited by the Global Minimum Size Range, and is floored at the Equity Universe Minimum Size Requirement. Other differences are formatting, line-break, diagram, and footnote-placement changes.
2026-10-02 MSCI China v2026.02 → v2026.08 M4 Selection and constituent count Minor The updated document deletes footnote 20, which defined how the Interim Market Size-Segment Cutoff is calculated during an Index Review. The removed text specified use of post-review Number of Shares and Foreign Inclusion factors, no limitation by the Global Minimum Size Range, and a floor at the Equity Universe Minimum Size Requirement. The main formula for the Initial Segment Number of Companies is otherwise unchanged.
2026-10-02 MSCI China v2026.02 → v2026.08 M7 Buffers and turnover control Editorial The updated section replaces "Investable Market Indexes" with "IMI" and adds a trademark symbol to "GIMI™," while reflowing text and relocating a footnote. All liquidity thresholds, listing-priority rules, and the 0.5 Liquidity Adjustment Factor requirements remain unchanged.

2026-10-02 MSCI ACWI v2026.02 → v2026.08 M4 Selection and constituent count Minor The light-rebalancing addition rule narrows the exclusion for securities with extreme price increases.

The exceptions to these thresholds are also revised to cover size-segment migrations, deletions from the IMI in connection with Micro Cap additions, and FOL-driven FIF changes, while retaining corrections.

Their treatment depends on 1.8x market-capitalization cutoff tests: smaller constituents remain Small Caps, while larger constituents are deleted from the Small Cap Index, retained in the investable universe, and reconsidered at the next Index Review.
