According to the IMF's latest World Economic Outlook report, Poland ranks 21st globally by nominal gross domestic product, estimated at USD 1.04 trillion in 2025, just behind Switzerland at a similar level.
The ranking is expected to remain unchanged in 2026, with Switzerland projected at USD 1.15 trillion and Poland at USD 1.13 trillion.
Six months earlier, in its October 2025 report, the IMF had forecast Poland would surpass Switzerland this year. The revision reflects updated historical data from Swiss authorities, Polish state news agency PAP reported.
The IMF now expects Poland’s economy to exceed Switzerland’s in 2028, when its nominal GDP is projected to reach about USD 1.25 trillion.
Saudi Arabia currently ranks 19th, with a GDP of around USD 1.28 trillion, while Taiwan, at about USD 920 billion, follows Poland.
In terms of purchasing power parity, Poland also ranks 21st globally, behind Taiwan and ahead of Australia, according to IMF data.
Polish Finance Minister Andrzej Domański said the revision to Switzerland’s data does not affect Poland’s ambitions to join the Group of 20, noting that the bloc does not strictly consist of the world’s 20 largest economies but also includes key regional players.
Current members include Argentina and South Africa, which rank lower in global GDP terms.
Poland is taking part in G20 meetings this year, including a gathering of finance ministers in Washington on Thursday and a leaders’ summit in December, effectively replacing South Africa, although South Africa remains a formal member of the group.
The shift follows a US decision not to invite South Africa amid a dispute over the treatment of white farmers.
Announcing this year’s US presidency of the G20, Secretary of State Marco Rubio said in December that Poland, "a nation that was once trapped behind the Iron Curtain but now ranks among the world's 20 largest economies, will be joining us to assume its rightful place in the G20."
He added: "Poland’s success is proof that a focus on the future is a better path than one on grievances. It shows how partnership with the United States and American companies can promote mutual prosperity and growth."
