Developed and Emerging Markets — How They Differ
Index providers sort the world's stock markets into groups, chiefly developed and emerging. This lesson explains where India sits, what the MSCI Emerging Markets Index held on 30 September 2026, and what its country weights show about concentration and change.
Two groups of markets
Index providers such as MSCI classify each country's stock market into a group. The two main groups are developed markets and emerging markets. The classification is the index provider's, and it decides which index a country's shares go into.
MSCI classifies India as an emerging market. Indian shares are therefore part of the MSCI Emerging Markets Index, and of MSCI ACWI, which combines both groups. They are not part of MSCI World, which covers developed markets only.
What the emerging-markets index held
On 30 September 2026 the largest country weights in the MSCI Emerging Markets Index were Taiwan 28.94%, South Korea 21.4%, China 19.8% and India 10.65% (MSCI factsheet).
The index spans the whole emerging-markets group, yet the first three countries together made up 70.14% of it. A broad-sounding index can be concentrated in a few countries, because it is weighted by market value and not spread evenly.
How far weights can move
India's weight in the same index was 18.12% on 30 June 2025. Fifteen months later it was 10.65%. India remained in the index throughout.
A weight is a share of the total. It rises or falls as a country's market value changes relative to the others. A falling weight therefore does not by itself say whether that country's market went up or down; it says the country became a smaller part of the whole.
What the labels do not tell
Neither group's returns can be predicted from its label. A fund tracking either group carries market risk, and for a rupee investor it carries currency risk in both directions. The label describes how a market has been classified, not how it will perform.
Rules at a glance
An emerging-markets fund seen from India
Omar, 42, a resident in Kolkata, already holds Indian shares and looks at an overseas fund that tracks the MSCI Emerging Markets Index.
Two things follow from the index's make-up. Part of what the fund holds is Indian shares again: India was 10.65% of the index on 30 September 2026. And most of the rest sits in three markets, Taiwan, South Korea and China, which together were 70.14%. The fund's result depends heavily on those few markets and on the exchange rate, and it can go either way.
Adding up the weights
- Weights on 30 September 2026 (MSCI factsheet): Taiwan 28.94%, South Korea 21.4%, China 19.8%, India 10.65%.
- Three largest together: 28.94 + 21.4 + 19.8 = 70.14%.
- Four largest together: 70.14 + 10.65 = 80.79%.
- All other emerging markets together: 100 − 80.79 = 19.21%.
- Change in India's weight from 30 June 2025: 18.12 − 10.65 = 7.47 percentage points lower.
Result. On that date four countries made up 80.79% of the index and every other emerging market shared 19.21%. Of every ₹100 in a fund that held the index exactly, ₹10.65 was in Indian shares, against ₹18.12 fifteen months earlier. These are snapshots and will have changed since.
Key points
- MSCI classifies country markets into groups, chiefly developed and emerging; India is classified as emerging.
- Indian shares are in MSCI Emerging Markets and MSCI ACWI, but not in MSCI World.
- MSCI Emerging Markets on 30 September 2026: Taiwan 28.94%, South Korea 21.4%, China 19.8%, India 10.65%.
- India's weight in that index was 18.12% on 30 June 2025: weights can change a great deal in a short time.
- A few countries can account for most of an index, and neither group's returns can be predicted from its label.
Common misunderstandings
- India is not in MSCI World: it is classified as an emerging market and sits in MSCI Emerging Markets and MSCI ACWI.
- An emerging-markets index is not spread evenly across emerging countries: three countries made up 70.14% of it on 30 September 2026.
- A lower index weight does not mean a country left the index or that its market fell: weights are relative shares of market value.
- The label 'emerging' or 'developed' is not a forecast: neither group's returns can be predicted from it.
Questions people ask
Who decides whether a market is developed or emerging?
The index provider. In MSCI's classification India is an emerging market.
Did India drop out of the index when its weight fell?
No. India remained in the index throughout; its weight fell from 18.12% to 10.65% as relative market values changed.
Does an emerging-markets fund hold Indian shares?
A fund tracking MSCI Emerging Markets does, since India is part of that index: 10.65% on 30 September 2026.
