In April 2025 when the International Monetary Fund (IMF) released its World Economic Outlook, India was seen overtaking Japan to become the world’s fourth largest economy by the end of 2025-26. One year later, India has slipped to the sixth position on the largest economies rankings, with the United Kingdom reclaiming its spot as the fifth largest economy.In fact, IMF’s latest World Economic Outlook (April 2026) sees India sitting at the sixth spot this financial year too. This projection comes even as India has grown better than expected in FY26 and is seen retaining its tag of being the world’s fastest growing major economy.What has led to the sudden fall? Why has India dropped to the sixth position, falling behind the UK, instead of overtaking Japan to become the fourth largest economy? And what does this setback mean for its dream of becoming the third largest economy by the end of this decade? We decode:

Data drive: India projected as 4th largest, but fell to 6th spot

First let’s look at some IMF data to see which way the Indian economy was headed in April 2025, and what the April 2026 outlook data suggestsAs per April 2025 estimates of IMF, India’s economy would have been at $4601.225 billion at the end of FY 2025-26, overtaking Japan which was estimated at $4373.091 billion. The UK at the 6th spot was projected to have a nominal GDP of $4040.844 billion.However, as per the April 2026 estimates, India’s economy had a nominal GDP of $4,153 billion at the end of FY 2025-26, with the UK overtaking it with $4,265 billion GDP. Japan’s GDP is seen at $4,379 billion.As the above estimates show, India’s GDP estimates have seen a drop over one year, while UK’s nominal GDP has grown better than expected. Japan has been steady.So, what went wrong? Blame the rupee and GDP data itself!

Rupee Depreciation Blow & New GDP Series

The first thing to understand is that IMF’s data on the size of a country’s nominal GDP is in dollar terms. Hence, with global rankings based on dollar‑denominated GDP, they are highly sensitive to exchange rate movements. The biggest party pooper for India’s dream of becoming the fourth largest has been the rupee’s slide. The Indian currency has depreciated more than expected over the last year, dropping from 84.57 versus the US dollar in 2024 to 88.48 in 2025, as per IMF data. The IMF estimates see it at 92.59 this year.Several factors have contributed to the rupee’s decline, including capital outflows, uncertainty related to India-US trade deal up until February, and the recent Middle East conflict which has raised crude oil prices and India’s import bill. Also, the RBI while actively managing volatility in the forex market, is not targeting any particular level of the rupee.Arun Singh, Chief Economist, Dun & Bradstreet India says that India’s recent slip to sixth place in global GDP rankings does not reflect a weakening of the economy, but is largely the result of currency conversion effects and a one‑time statistical revision.The rupee’s depreciation from 2024 to 2026, has mechanically compressed India’s GDP in dollar terms, effectively halving apparent growth despite strong domestic expansion, says Arun Singh.According to Ranen Banerjee, Partner and Leader, Economic Advisory Services, PwC India, GDP in US dollar terms would shave off with rupee depreciation. “We have had almost 7-8% depreciation over the last few months owing to the conflict and portfolio outflows. Thus, in effect in US dollar terms, it is close to shaving out almost a year’s nominal GDP,” he tells TOI.And it’s not just about the Indian economy. The United Kingdom which has overtaken India to bag the 5th spot again also has economic factors working in its favour. UK’s GDP growth at 0.5% has recently beaten forecasts of 0.1% by a wide margin. Not only that, its currency – pound – has actually appreciated against the US dollar.The second factor that has impacted the rankings is India’s adoption of a new base year for its latest GDP series. As per the new data, which also makes use of a more refined methodology, the size of India’s nominal GDP in rupee terms has gone down. Sample this: As per the older base year of 2011-12, India’s GDP at the end of 2025-26 would have been Rs 35,713,886 crore. But under the new series, it is estimated to be Rs 34,547,157 crore. The new calculation methodology and base year revision presents a more accurate picture of the size of the Indian economy.Hence the currency effect has been compounded by a one‑time downward revision following India’s shift to a new GDP base year, which has lowered reported nominal levels without affecting real activity.

Does India’s drop to 6th indicate fundamental weakness?

Experts are confident that India’s growth story is intact and fundamentally strong, a fact that is reflected in projections of it continuing to be the world’s fastest growing major economy. They see technical factors behind the current slip, rather than any deterioration in economic fundamentals.It’s also interesting to note that while India will be the sixth largest economy in FY27, in the upcoming financial year, it is likely to overtake both the UK, and Japan to bag the fourth spot.Arun Singh of Dun & Bradstreet India explains this resilience with numbers:IMF World Economic Outlook (April 2026) data show that India’s GDP at current prices in domestic currency rose strongly from ₹318 trillion in 2024 to ₹346.5 trillion in 2025 and further to ₹384.5 trillion in 2026, translating into robust nominal growth of about 8.9% in 2024–25 and nearly 11% in 2025–26, among the fastest globally. In contrast, other large economies recorded more moderate domestic nominal growth – around 5% in the US, roughly 4% in China, 3–5% in the UK, 3–3.5% in Germany, and lower or volatile growth in Japan – underscoring India’s strong underlying momentum. In times of global economic turmoil, while GDP growth is expected to take some hit, most agencies and experts have pegged India’s growth to be strong. Incidentally, the IMF has even marginally raised its GDP growth forecast for FY27 to 6.5% despite the ongoing Middle East conflict.

“In India, growth for 2025 is revised upward by 1.0 percentage point relative to October, to 7.6 percent, reflecting the better-than-expected outturn in the second and third quarters of the fiscal year and sustained strong momentum in the fourth quarter,” IMF said in its latest outlook. “For 2026, growth is revised upward moderately by 0.3 percentage point (0.1 percentage point relative to January) to 6.5 percent, led by positive contributions from the carryover of the strong 2025 outturn and the decline in additional US tariffs on Indian goods from 50 to 10 percent, which outweigh the adverse impact of the Middle East conflict. Growth is projected to stay at 6.5 percent in 2027,” it added.

Will India become 3rd largest anytime soon?

The rupee depreciation and the nominal GDP revision has also pushed back India’s dream of becoming the third largest economy by the end of this decade. In the October 2025 estimates, IMF had said that India will overtake Germany to become third largest by FY30. However, the April 2026 projections see it reaching the third rank only by FY 2030-31.Experts point to the rupee’s depreciation versus the dollar to note that the road ahead is likely to be uncertain. Madan Sabnavis, Chief economist, Bank of Baroda is confident that India will continue to do well in the coming years.“We will definitely improve in terms of GDP growth which will be higher than that of other countries especially UK and Japan which are just above us. However, the rupee value will finally determine how India gets placed on the global scale,” he told TOI.Ranen Banerjee of PwC India sees rupee beginning to get support with the conflict containment, relatively lower oil prices and portfolio flow reversals with valuations getting attractive in recent times. “Thus, we should not be experiencing any further sharp depreciation of the rupee in the immediate term provided the conflict does not escalate and oil prices relatively softening from their highs and come down to a range of $85-90 a barrel,” he says.For Arun Singh of Dun & Bradstreet, looking ahead, India’s relative position in US dollar‑based GDP rankings will remain highly sensitive to currency movements rather than domestic growth dynamics. “Continued global dollar strength or capital‑flow volatility may cause periodic slippage in rankings despite robust fundamentals. Sustaining external macro stability and limiting undue rupee volatility will be crucial for India’s strong growth performance to translate more fully into higher global economic rankings,” Arun Singh told TOI.The Indian economy, largely driven by domestic fundamentals, is not immune to external shocks. High US tariffs of 50% from August 2025 to early February, and the ongoing US-Iran war have spelt back-to-back shocks for the economy. Even as experts stress on the resilience of the growth story, the vulnerability to higher crude oil prices, and other global supply chain disruptions is a reality. In such a scenario, India may well have to contend with fluctuating world rankings, while banking on its strong GDP growth to tide over disruptions.
