GDP growth by country to 2030: the IMF's October 2026 forecasts put Suriname first at 15.4% a year as its offshore oil comes on stream, while Italy and Japan grow less than 0.7%.

Which country has the fastest growing economy?

Suriname leads all 189 economies in the IMF's rankings, projected to grow 15.4% a year on average from 2026 to 2030, driven almost entirely by two oil years: 28.2% in 2028 and 43.0% in 2029. Guyana, already an established offshore oil producer, ranks second at 10.8% a year. India is the fastest growing large economy at 6.9% a year, ninth of 189, with 6.9% projected for 2026 rising to 7.0% that same year.

China averages 3.9% a year over the period, ranking 58th, while the United States averages 2.1%, ranking 137th. In all, 33 economies are projected to grow 5% a year or more through 2030.

Why is Suriname projected to grow so fast after 2027?

Suriname's projected surge rests almost entirely on the GranMorgu offshore oil field in Block 58, operated by TotalEnergies with a 40% stake, alongside APA Corporation at 40% and the state company Staatsolie at 20%. The partners took a final investment decision in October 2024 on a project of around $12 billion. A floating production vessel with capacity for 220,000 barrels a day is due to start producing in mid-2028, which is why the IMF projects growth of 28.2% in 2028 and 43.0% in 2029.^{3, 4}

In a September 2026 update, TotalEnergies said construction of the production vessel and manufacturing of subsea equipment were progressing, with drilling and offshore installation activities scheduled to begin in early 2027.⁴ The World Bank's October 2026 Latin America and the Caribbean Economic Update also projects Suriname's economy will grow 21.5% in 2028, the year GranMorgu starts producing, compared with 3.9% in 2026 and 4.6% in 2027.³ Because Guyana's economy entered 2026 roughly six times larger in dollar terms, Suriname's faster percentage rate in 2028 does not mean it overtakes its neighbour in output.^{3, 4}

Why do Germany, France, Italy and Japan grow so slowly?

Germany averages 1.0% a year to 2030, France 0.9%, Italy 0.7% and Japan 0.6%, all well below the global median of 2.9%. Japan's position reflects several overlapping pressures. The IMF projects Japan's nominal GDP at $4.34 trillion in 2026, and the country is expected to slip to sixth place in global GDP rankings by 2027 as India and the United Kingdom overtake it.⁶

According to reporting by AFP cited in TradingView, Japan grapples with structural challenges including an ageing population and rising import costs.² The Bank of Japan has raised interest rates to their highest levels in three decades in response to sustained consumer price increases, and higher energy prices linked to the Iran war have added to inflationary pressures, while yen weakness has increased the cost of imports.² Qazinform, citing Jiji Press, notes that the decline in Japan's GDP ranking is largely attributed to the depreciation of the yen against the US dollar, although slower economic growth has also contributed.⁶ The eurozone as a whole is estimated to grow 1.1% in 2026.¹

What do economists say about India overtaking China in growth?

India's chief economic adviser, V. Anantha Nageswaran, said in an interview published Oct 8 that India is expected to overtake Japan to become the fourth-largest economy in nominal terms by the end of March 2027, ranking behind the United States, China and Germany.⁵ The IMF's October 2026 World Economic Outlook raised its forecast for India's economic growth in 2026 to 7%, and projects India's nominal GDP at $4.52 trillion in 2027, ahead of Japan's projected $4.47 trillion.^{2, 6}

Speaking at the release of the IMF's regional economic outlook for Asia-Pacific, the IMF's Asia Director Krishna Srinivasan said India entered the current energy price shock with strong economic fundamentals, citing robust growth, fiscal prudence and substantial foreign exchange reserves as factors that helped the country respond to the shock.² Nageswaran acknowledged that youth unemployment, particularly among women in urban areas, remains a problem, and that progress in addressing it has been slow.⁵ He also said India must focus more on agriculture as a driver of future growth.⁵

How might the Middle East war reshape these growth forecasts?

The Middle East war's energy shock has already reshaped the 2026 numbers sharply. Al Jazeera reports that the IMF cited prolonged disruption to shipping in the Strait of Hormuz, a conduit for one-fifth of global oil supplies in peacetime, as the reason for its downgraded regional outlook.¹ The Middle East and Central Asia region is the only one expected to experience negative growth in 2026, with GDP forecast to contract 0.3%, a sharp downgrade from the 1.9% expansion projected in April.¹

Saudi Arabia, which has partially offset the hit to its energy sector by boosting oil exports through the East-West pipeline, is still projected to record negative growth of 3.3% in 2026.¹ The IMF projects rebounds of 17.1% to 19.0% for Kuwait, Iraq and Qatar in 2027, so the five-year averages recover, but the path depends on how the conflict develops. The IMF warned that further escalation in conflicts could weaken growth, while a sustained easing of geopolitical and trade tensions could strengthen it.¹
