Between 2015 and 2025, almost every country in the world raised its statutory minimum wage in nominal terms. Governments announced the increases. Workers received more units of currency per hour or per month. The headline numbers looked like progress.
The question this analysis answers is a different one: after accounting for each country’s own inflation, did minimum wage workers end up with more purchasing power — or did rising prices absorb the gains before they arrived?
The answer varies by a factor of nearly four between the best and worst performers in this dataset. Poland produced the largest documented real-wage gain among the 17 countries here: 71 percent in 10 years. The United States produced the only documented real-wage loss: 24 percent over the same period, without a single legislative increase.
Between those endpoints sits a wide middle — countries that increased their floors, watched inflation eat much of the increase, and ended up with modest real gains or, in France’s case, none at all.
01 / What the numbers measure
Before the rankings: a note on what this index measures and what it does not.
Each country’s minimum wage is indexed to 100 at the earliest year for which wage.is holds both wage history data and a Consumer Price Index time series. That base year varies by country — 2015 for most, 2016 for the United Kingdom, 2018 or 2019 for several European countries. The CPI used is from the World Bank’s FP.CPI.TOTL series (2020 = 100), rebased to each country’s own start year for comparability.
The index answers one question: did the real value of the statutory minimum wage go up or down over the measurement period? It does not capture whether the starting level was adequate — Poland’s floor in 2015 was roughly €400 per month; the United Kingdom’s was £7.20 per hour. Nor does it capture the gap between the statutory floor and where wages actually sit in each labor market, which varies substantially.
A country with a low floor that rises fast scores well here. A country with a high floor that barely moves does not. The index measures trajectory, not level.
02 / The countries that built real purchasing power
Four countries stand out for sustained real-wage growth: Poland, South Korea, Japan, and the United Kingdom. Their paths differ, but each produced documented gains in purchasing power over the measurement window.
Poland leads by a significant margin. Its monthly statutory minimum rose from PLN 1,750 in 2015 to PLN 4,666 in 2025 — a 167 percent nominal increase. Polish CPI rose roughly 56 percent over the same period. The difference between those two numbers is a 71 percent real gain, the largest in this dataset. The gain was not linear: the 2022 inflation surge temporarily compressed real wages before further nominal increases pulled them ahead again. By 2025, workers at the Polish floor had substantially more purchasing power than in 2015.
South Korea followed a different arc. The government’s decision in 2018 to raise the hourly floor from KRW 6,470 to KRW 7,530 in a single step — a 16.4 percent increase, the largest since 2001 — drove a rapid real-wage expansion between 2015 and 2019. The real index reached 143 by 2019. Since then, South Korea’s nominal increases have moderated and inflation has persisted, leaving the real index essentially flat from 2021 through 2025 at around 145. A 45 percent real gain over 10 years; most of it front-loaded in the first four.

Japan is the most consistent performer in the set. Annual increments to the national weighted-average hourly floor — set via regional Minimum Wage Councils rather than a single legislative act — have been small but uninterrupted. From JPY 798 per hour in 2015 to JPY 1,121 in 2025, a 40 percent nominal increase. Japan’s CPI has been among the most stable in the developed world for most of this period, though post-2022 energy and import cost pressures changed that. Against a cumulative CPI rise of about 13 percent over 10 years, Japan’s consistent nominal increases translated into a 24 percent real gain — no single spectacular year, no reversals.
The United Kingdom takes a different shape. When the National Living Wage replaced the previous National Minimum Wage framework in 2016 at £7.20 per hour, it set a political target: close the gap between the statutory floor and living-wage benchmarks. A series of above-inflation increases followed — small in the early years, then larger from 2019 onward. By 2025, the NLW stood at £12.21 per hour, a 69 percent nominal increase from the 2016 base. The UK also experienced its most severe inflation episode in 40 years in 2022 and 2023, with CPI averaging 9.1 percent and 6.8 percent in those years respectively (ONS Consumer Price Index, annual averages). The government’s Low Pay Commission responded with larger-than-usual recommendations. The result is a real gain of 24 percent from 2016 to 2025.
03 / France and the indexation trap
France presents a result that is arithmetically precise and practically striking: six years of minimum wage increases, and essentially no real gain.
The SMIC — the Salaire minimum de croissance — is legally indexed to inflation. When the CPI rises above 2 percent, the SMIC triggers an automatic increase to protect the purchasing power of minimum wage workers. The mechanism worked exactly as designed from 2019 to 2025: nominal increases tracked inflation closely enough that the real index ended 2025 at approximately 99.8, essentially unchanged from 2019.
That is not a failure of the mechanism — it is the mechanism. The SMIC’s indexation clause was designed to prevent a real loss, not to generate a real gain. Workers at the floor in France in 2025 have roughly the same purchasing power as workers at the floor in 2019. They were not made worse off by inflation. They were not made better off by nominal increases either.
The contrast with Poland is instructive. Poland’s increases were above-inflation by design — a political commitment to close the wage gap with Western Europe. France’s increases were indexed to inflation by law — a commitment to maintain purchasing power, not to expand it. Both systems produced their intended outcomes. The real-wage trajectory looks very different.
Germany sits in a different position: a 14 percent real gain over 10 years, but with a volatile path. The 2022 legislative jump to €12.00 — 25 percent above the previous year’s floor — generated a spike in the real index, which then fell back as post-2022 inflation ran ahead of the subsequent Commission-guided increases. The 2025 figure of approximately 114 represents a genuine real gain over 2015, but workers who earned the minimum in 2021 and again in 2023 experienced two years where their purchasing power declined despite rising nominal wages.
04 / The countries where inflation won
A second cluster of countries produced nominal increases large enough to look like progress but not large enough — or fast enough — to outpace their domestic CPI.
Israel increased its monthly national minimum from ILS 4,650 in 2015 to ILS 5,880 in 2025, a 26 percent nominal increase. Israeli CPI rose roughly 18 percent over the same period. The real gain is approximately 7 percent in 10 years — positive, but modest for a decade’s worth of legislative action.
Peru and Hong Kong show similar patterns: nominal increases that ran slightly ahead of inflation, producing real gains in the range of 7–8 percent over the full period. In Peru’s case, the increases were irregular — concentrated in 2016 and 2022 with long flat periods between — while Hong Kong’s minimum wage is adjusted every 2 years through a statutory review mechanism.

Greece occupies a particular position in this dataset. The 2015 starting point is not a normal baseline — it reflects a floor that had been cut from approximately €751 per month to €586 in 2012 as part of troika fiscal adjustment conditions. Real wages at the floor in 2015 were already below their pre-crisis level. The subsequent recovery, from €586 in 2015 to €880 in 2025 (the floor rose to €880 on April 1, 2025, per the Greek Ministry of Labour), represents a 7 percent real gain from that depressed base. In absolute terms, workers at the Greek floor in 2025 had not fully recovered to pre-crisis purchasing power; in indexed terms from 2019, the trajectory is upward.
The US federal minimum wage requires its own category. The floor has not changed since July 2009. From 2015 to 2025, US CPI rose 32 percent. The $7.25 per hour floor, unchanged across that period, lost 24 percent of its real value over 10 years, and 36 percent of its value from its 2009 introduction date. A worker earning the federal minimum in 2025 had approximately $5.48 of 2015 purchasing power — not $7.25. According to BLS Characteristics of Minimum Wage Workers (2024), approximately 843,000 workers were paid at or below $7.25/hr directly — the population for whom the federal floor is the actual operative constraint. State minimums cover more workers at higher rates. But the federal floor is the statutory floor, and it is the only one in this dataset that declined in real terms.
05 / What the league table shows
Across 17 countries with sufficient historical data for this analysis, the median real-wage change over the measurement period is approximately 17 percent — Ireland, at +16.8 percent, is the median country. Nine of the seventeen countries produced real gains above 20 percent; two (France, the US) produced near-zero or negative real outcomes.

Several structural patterns emerge from the ranked list.
Eastern Europe converged fastest. Poland, Bulgaria, and Romania all rank in the top tier of real-wage growth. These countries started from a lower base in 2015 and have run above-inflation increases as part of an explicit catch-up strategy, supported by EU minimum wage guidance and domestic political pressure. Bulgaria’s real gain from its 2020 data baseline is the steepest trajectory in that sub-period.
Indexation-linked systems held steady. France and Israel both have minimum wage systems with strong inflation-indexation components. Both produced near-zero to modest real gains over their measurement windows. Neither saw a meaningful real loss; neither saw a meaningful real advance. The indexation mechanism functioned as designed.
Large political jumps produced short-term volatility. South Korea’s 2018 jump and Germany’s 2022 jump both created sharp real-wage spikes followed by partial retrenchment as inflation absorbed the gains. The long-run real gain is real, but the path was not smooth.
Inaction compounds over time. The US case demonstrates that doing nothing to the nominal wage does not produce a neutral real outcome. It produces a declining one. The 24 percent real loss over 10 years is the direct consequence of CPI rising without any corresponding floor adjustment.
06 / The 2022–2023 inflation episode as a stress test
The 2022–2023 global inflation surge acted as a stress test of minimum wage indexation systems worldwide.
Countries with frequent or automatic adjustments handled it better. France’s indexation triggered mid-year adjustments in 2022 and 2023, limiting real losses. The UK’s Low Pay Commission recommended its largest-ever increases in 2023 and 2024 in direct response to the CPI data. Poland’s government legislated above-inflation increases in each year of the surge.
Countries with infrequent or politically driven adjustments absorbed larger real hits. Germany’s Commission-guided process was not designed to respond intra-year to sudden CPI movements, and the 2022 real gain was partially reversed in 2023. South Korea’s annual adjustment process compressed the gains of the 2018–2019 expansion.
The inflation episode also made visible something that indexation arithmetic tends to obscure: the lag between when prices rise and when wages are adjusted is not neutral. A worker whose wages are indexed annually experienced roughly 12 months of real-wage erosion between each adjustment. A worker in a country with mid-year triggers experienced roughly 6 months. Annual averages smooth over this lag. Workers living through it did not experience smooth averages.
Note on Turkey: Turkey is excluded from the ranked chart. Its five-year real-wage index from 2020 to 2025 is approximately +30 percent, but that figure depends heavily on which official CPI series is used and carries significant measurement uncertainty given the documented divergence between official TUIK inflation and independent estimates during 2021–2023. A separate analysis with source methodology disclosed is warranted before Turkey appears in a cross-country ranking.
Wage figures come from wage.is country data files, sourced from official government labor ministry publications. CPI data is from the World Bank FP.CPI.TOTL series (2020 = 100), rebased to each country’s earliest available year. Real growth = (wage_end / wage_base) ÷ (CPI_end / CPI_base) − 1. Countries with fewer than 5 years of wage history or missing CPI coverage are excluded. The UK base year is 2016 (NLW framework launch). All CPI data is annual; the index does not capture intra-year inflation lag. The US figure reflects the federal floor only. France’s SMIC indexation trigger (Code du travail, Article L3231-5) references the CPI for the lowest-income household quintile excluding tobacco; this analysis uses the World Bank all-households series for cross-country consistency.
