Which Country Gives the Highest Stock Market Returns Over 1, 10 and 20 Years? Compare India vs US vs the World

Ask ten investors which stock market gives the best returns and you will get ten different answers — each correct for a different time period. The truth is more nuanced: the "best" market depends entirely on whether you measure one year, ten years, or twenty-five years, and whether you account for the currency your money lives in. Here is what the data actually says.

2025: The Year the US Fell Behind

In 2025, the United States stock market — long considered the default home for global capital — was outpaced by six major markets simultaneously. According to Visual Capitalist's year-end review published in January 2026 and citing Yahoo Finance and TradingView data, Japan's Nikkei 225 led all major markets with a 26% return, four percentage points ahead of the UK's FTSE 100 in second place at 22%. Germany, China, and Mexico also exceeded the S&P 500's 16.39% return.

The same Visual Capitalist report noted that the US market's underperformance came despite S&P 500 reaching record highs in 2025 — a reminder that "record high" and "best in class" are not the same thing. India's Nifty 50, by contrast, had a more muted 2025, hurt by currency pressures and global risk-off sentiment, according to Trading Economics data updated in June 2026.

One important caveat: according to Visual Capitalist, when the US announced sweeping tariffs on 2 April 2025 (Liberation Day), India experienced the lowest and shortest decline among all major markets. Only 12% of India's economy depends on goods exports, and merchandise exports to the US make up just 2.1% of India's GDP — giving it natural insulation from trade-war turbulence.

"The U.S. stock market soared in 2023 and 2024 — with returns more than twice the historical average. That trend reversed in 2025." — According to University of Wisconsin–Stevens Point blog, January 2026, citing S&P 500 index data

The 10-Year Picture: USA Takes the Crown

Zoom out to a decade, and the rankings shift. According to Visual Capitalist's April 2025 report citing HelloSafe data, the S&P 500 delivered a 17% annualised return from March 2015 to March 2025 — the highest of any major stock exchange globally over that period. A Rs 10,000 investment in the S&P 500 in 2015 would have grown to nearly Rs 50,000 by 2025. (Source: Visual Capitalist, April 2025)

India was not far behind. According to Samco's March 2026 analysis, the Nifty 50 delivered approximately 11.7% annualised returns over the last 10 years (2016–2026), while the S&P 500 returned 14.8% in the same window — giving the US a slight edge in the most recent decade. However, over 20 years (2006–2026), the same Samco analysis found India's Nifty 50 delivered ~11.5% annually versus the S&P 500's ~10.7% — meaning India outperforms on longer timelines.

The reason for the gap in the last decade is simple: the US tech supercycle. Apple, Microsoft, Nvidia, Alphabet, and Amazon collectively drove S&P 500 returns that no single country could replicate over a sustained 10-year window. (Source: Samco Knowledge Center, March 2026)

The Argentina Warning: Big Numbers, Bigger Risks

Argentina's MERVAL index returned an extraordinary 360% in 2023, according to Wikipedia's MERVAL entry, and according to lazyportfolioetf.com data, Argentina has been the best-performing market over the last five years with a +27.69% annualised return. That headline number is technically correct — and almost entirely misleading.

Argentina's annual inflation exceeded 100% in 2023 for the first time in three decades, according to Wikipedia. A 360% nominal return in a market where everything costs three times more means the real, inflation-adjusted return is sharply negative. When measured in US dollars — the currency that matters for cross-border comparison — those gains collapse further due to the peso's severe devaluation. For Indian investors, the lesson is critical: always adjust for inflation and currency before comparing emerging-market returns.

India vs USA: The Real Comparison

According to Weekend Investing's November 2025 analysis, a commonly circulated chart shows Nifty 50 returning 1,400% over 25 years versus the S&P 500's 321%. That comparison is flawed, the same analysis notes, because it compares rupee returns against dollar returns without accounting for the Indian rupee's depreciation against the US dollar. When Nifty's returns are recalculated in dollar terms, the outperformance narrows to 682% versus 321% — still a win for India, but with a much smaller margin.

The honest conclusion, according to Samco's March 2026 research: over 20 years, India and the US have delivered almost identical returns in dollar-adjusted terms, with India holding a slim edge that widened significantly only after India's post-COVID rally from 2020 onwards. For Indian residents investing in rupees, domestic markets make clear logical sense. For those with dollar exposure or NRI status, the calculus is more balanced.

What Should Indian Investors Do?

The data does not crown a single winner — it reveals a portfolio strategy. Japan outperformed in 2025; the US dominated 2023 and 2024; India outperforms over 20-year rolling periods; and Argentina shows why high nominal returns can be a trap. According to the Novel Investor's international returns tracker, no single country leads every year — the rankings rotate unpredictably across developed and emerging markets.

Rupee depreciation is also a factor working quietly in India's favour for domestic investors. Because living expenses are in rupees, Indian investors do not need dollar-denominated returns to build real wealth — a structural advantage the raw return charts do not capture.
