2006–2025 — quarterly data, all economies indexed to 100 in Q1 2016
Key observations
Italy is the single most striking long-run story: its GDP in Q1 2006 was roughly 6% larger than in Q1 2016. The 2008–09 global financial crisis hit Italy hard, then the 2011–13 eurozone sovereign debt crisis caused a second recession. By 2016, Italy had spent a decade going backwards — the textbook "lost decade" in the G7.
The 2008–09 global financial crisis caused sharp quarterly contractions across the G7: Germany fell ~8% peak-to-trough (very export-dependent), Japan ~9.5% (trade collapse), Italy ~6%, the UK ~5%. The US and Canada fell ~3%, shielded partly by fiscal stimulus and, in Canada's case, well-regulated banks.
US leads the G7 since 2016 by a wide margin — roughly +22% cumulative real growth from Q1 2016 to Q4 2025 — driven by strong consumer spending, fiscal stimulus (CARES Act, IRA), and tech-sector productivity gains.
The COVID-19 crash (Q2 2020) was even sharper than 2008–09. The UK experienced the deepest drop (~19% from Q4 2019 to Q2 2020), Italy and France also fell sharply (~12–13%), while the US showed a shorter but severe contraction before rapid recovery.
Recovery speed varied dramatically: the US regained pre-COVID levels by Q2 2021, while European economies took until late 2021 or early 2022. The quarterly view reveals different policy responses and structural flexibility.
Germany is the weakest economy post-2022: essentially flat from Q1 2022 onwards. The quarterly data shows persistent stagnation quarter after quarter, revealing structural problems beyond cyclical weakness.
Canada's strong headline growth (+15-16% since Q1 2016) is substantially driven by population expansion via high immigration — GDP per capita tells a much more sober story. See the per-capita page.
