Fastest-growing economies (2026)

By Maria Cortez · 2026-04-30

In short: By latest-year GDP growth, Guyana is the fastest-growing economy on earth at about 43.8% — an oil-fuelled surge from a small base. Other fast growers include Niger (10.3%), Georgia (9.7%), the Kyrgyz Republic (9.0%) and Rwanda (8.9%). Small or resource-driven economies dominate growth rankings because a few big projects move the percentage far more than they would in a $20-trillion economy. Figures are annual real GDP growth from World Bank Open Data.

The fastest-growing economies are rarely the household names. The growth charts are dominated by small or resource-rich countries, where one big shift moves the percentage dramatically.

Full list: fastest-growing economies. Guyana’s rate is in a class of its own — an offshore oil boom that is enormous relative to its small population, so per-person figures have rocketed too.

The small-base effect

Growth is a rate. A new mine or oilfield can add 10% to a small economy and almost nothing to a giant. That’s why you don’t see the largest economies — the US, China, Germany — anywhere near the top of growth tables. Mature economies grow steadily in the low single digits.

Growth vs wealth

Fast growth does not mean a country is rich. Several fast-growers remain low- or lower-middle-income; they are catching up from a low GDP per capita. Sustained growth over decades is what turns a poor country into a rich one — see GDP vs GDP per capita.

Bottom line

Guyana is today’s growth champion, but the list churns year to year as resource projects and recoveries come and go. To see a specific country’s latest growth rate, open its profile page or run a head-to-head comparison.

Frequently asked questions

What is the fastest-growing economy in the world?

By latest reported annual GDP growth, Guyana is the fastest-growing economy at about 43.8%, driven by a massive offshore oil boom that is huge relative to its small economy. Source: World Bank, latest available year.

Why are small countries usually the fastest-growing?

Growth is a percentage, so a country with a small base grows fast when one large project (an oilfield, a mine, post-crisis recovery) lands. The same project in a $20-trillion economy would barely register. That's why giants like the US or China rarely top growth charts.

How fast is the US or China growing?

Large economies typically grow a few percent a year — far below the double-digit rates of the fastest small economies. Check the latest figure on each country's profile page, which shows GDP growth for its most recent reported year.
