Why Luxembourg's output is divided by the wrong population

Where the workers sleep and where they work

The Luxembourg economy held 522,200 jobs in 2025 on the International Monetary Fund's count, and 299,200 of them were filled by residents. The remaining 223,000 posts were worked by people who crossed a national border to reach them and went home to France, Belgium or Germany at the end of the shift. A widely quoted breakdown of the same labour market puts it at 445,000 jobs held by 120,000 Luxembourgers, 120,000 foreign residents and 205,000 cross-border commuters. The two counts are taken on different bases, and they agree on the same finding: Luxembourgers are a minority of the people working in Luxembourg.

None of the commuters sit in the population figure. Luxembourg had 690,959 residents on 1 January 2026, and dividing the output of 2025 by a resident population of that size is what produces 147,252 United States dollars a head, or 156,542 at purchasing power parity. Output was made by 522,200 workers and divided among 690,959 residents. The arithmetic is correct and it describes a country whose shop floor is larger than its dormitory.

The balance of payments shows the same shape from the other side. Luxembourg ran a surplus on services worth 33.8% of gross domestic product in 2025 against a deficit on net factor income worth 29.9%, which is money earned inside the country leaving it again, to the foreign owners of the firms and to the households of the people who staffed them. What stays behind is the tax. Commuters pay income tax in Luxembourg while their schooling was partly financed by the state they live in, and the government has never shared those receipts with local authorities on the French border, an arrangement read by some as one of the keys to Luxembourg's growth and by the border regions as growth taken at their expense.

Transport policy follows from the same fact. Luxembourg became the first country to abolish fares on public transport on 29 February 2020, funded almost entirely from taxation, and the capital's tram line reached the airport in 2025, which lets a business traveller land and work without a car. Ridership has grown consistently since, and operating costs had nearly doubled by 2025.

What Luxembourg sells when it owns nothing

Britannica's account of the national endowment is blunt. The once copious iron ore deposits were worked out by the 1980s, there are no energy resources beyond water and timber, and the country has almost nothing that predisposes it to agricultural or industrial development, so the roots of its growth lie in the use of capital and in the adaptability of its workforce. Hydroelectric dams on the rivers meet about a fifth of energy needs on the same account, and imports cover the rest. Agriculture occupies 1 to 3% of the workforce, was 2.1% in 2010 across 2,200 holdings averaging 60 hectares, and the Moselle vineyards press about 15 million litres of dry white wine a year, most of it drunk inside the country.

What the country has manufactured for a century instead is legal form. The Holding Act of 1929 arrived a year after the founding of the Luxembourg Stock Exchange, and it let a company hold financial assets without being taxed twice on them. Within three years the capital registered in holding companies had passed 2 billion Luxembourg francs. The Ford Investment Company, set up early in 1930, used the regime to avoid United Kingdom tax on the dividends of its European subsidiaries and to buy factories for them. Around the statute grew a standing network of lawyers, banks, notaries and the political elite, maintaining regulatory codes, legal expertise and shell companies, and in 1963 the first Eurobonds were listed on the Luxembourg exchange.

The method has been run again since, on new subjects. SES was created with government backing in 1986 to install and operate a satellite television system for Europe, and its first Astra satellite went up on an Ariane rocket in December 1988; the company now sits at Betzdorf as the largest satellite services operator in the world by revenue. In February 2016 the government announced that it would try to start an asteroid mining industry, chiefly by writing a legal framework and regulatory incentives for it. By June 2016 it had committed more than 200 million United States dollars in research, demonstration and equity, by April 2017 three space mining corporations had established headquarters in the country, and in August 2017 a law took effect giving private operators title to whatever they extract in space, whether or not they are Luxembourgish. The contribution to the European Space Agency in 2015 was 23 million euros.

How steel built the south and then left

The event that made industrial Luxembourg was the introduction of English metallurgy in 1876, followed by the basic Bessemer process in 1879, which finally allowed the high-phosphorus ore of the Lorraine field to be turned into steel. That field runs into the south-western corner of the grand duchy, and the deposits under the red rocks are described in Luxembourg: geography. ARBED was founded in 1911. By the 1960s iron and steel were as much as 80% of the value of everything Luxembourg exported, which is the monolithic dominance the country's own histories blame for what happened next.

Then world demand for steel slumped. The crisis in metallurgy ran from the mid-1970s to the late 1980s and came close to pushing the country into recession, precisely because the sector dominated everything else. The state took a 31% holding in ARBED from 1974 and began restructuring. A Tripartite Coordination Committee of ministers, management and union leaders managed the contraction without major social unrest, which is the origin of the Luxembourg model of social peace, described in the country's own histories as a myth as much as a mechanism. By the late 1970s ARBED was the only steelmaker left standing, and the ore itself was exhausted by the 1980s.

The company outlived the ore. ARBED merged with Aceralia and Usinor to form Arcelor, dated to 2001 by Britannica and to 2002 in the Wikipedia account, and Arcelor later merged with Mittal Steel to create ArcelorMittal, the largest steel company in the world at its formation. Industry survived in a different form, diversifying into chemicals, rubber, motor-vehicle tyres and fabricated metals, mostly in foreign-owned plants. Esch-sur-Alzette, Pétange, Differdange and Dudelange grew on iron, and their growth slowed with it. Meanwhile the financial sector, which had begun gaining weight at the end of the 1960s, was supplying a third of all tax receipts thirty-five years later.

Why the fund business chose this address

The fund business is what the country is now for, alongside private banking and reinsurance. Assets under management in Luxembourg-domiciled funds passed 8 trillion euros for the first time in 2025 and stood at 8.2 trillion euros at the end of the year, more than 50% above where they were at the end of 2020. Alternative funds are now 35% of the total. The domestic market is relatively small and the centre is international by design, specialising in cross-border fund administration for promoters based somewhere else.

The detail underneath the headline is what a servicing industry looks like. Exchange-traded fund assets domiciled in the country reached 531.8 billion euros at the end of 2025, growing 19.5% over the year. Of the 272 European long-term investment funds established anywhere in the European Union at that date, 150 were domiciled in Luxembourg, and of those genuinely distributed across borders the country accounted for 77%. More than 2,400 green, social, sustainable and sustainability-linked bonds were listed on the Luxembourg Green Exchange, 43% of the world market, with over 1.3 trillion euros issued through them. The stock exchange passed 50,000 listings, and every third new bond issue anywhere in the world is listed there.

The register kept growing in 2025. More than 58 new entities were licensed, among them the banks Cecabank, Fundbank and Rothschild and Co Wealth Management, four crypto asset service providers including Coinbase, Bitstamp, Zodia Custody and Clearstream, Alipay as an electronic money token issuer, and Ripple and dtcpay as electronic money institutions. Life insurance premiums reached a record 31.1 billion euros in 2025, up 16.2% on a year that was itself a record, with non-life at 19.8 billion. In 2013 services produced 86% of output and the financial sector alone 36%, against 13.3% for industry and 0.3% for agriculture, and in 2022 the largest company category on the register was finance, insurance and real estate, with 89,748 firms against 31,658 in services.

Why the tax question never quite closes

Nearly 90% of the companies operating in Luxembourg are foreign, and about 40% of them carry on no meaningful economic activity in the country at all: they hold assets there. That is the intended output of a legal industry, and it is also the reason the country's reputation has been argued about for a century. The Holding Act of 1929 has been described by its historians as the foundation of the financial centre rather than a footnote to it, and the same infrastructure of codes, expertise and shell companies that attracted the Ford Investment Company in 1930 attracted a great deal else afterwards.

The pressure has been external and it has worked in stages. The G20 put Luxembourg on a grey list of jurisdictions with questionable banking arrangements in April 2009, and the country was removed from it the same year after adopting the OECD standards on exchange of information. The classic tax-exempt 1929 holding company was outlawed on 31 December 2010 after the European Commission judged it illegal state aid. In 2011 the Tax Justice Network placed Luxembourg third on its Financial Secrecy Index, behind the Cayman Islands by a small margin. In November 2014, days after Jean-Claude Juncker took over the European Commission, the LuxLeaks disclosures reported that Luxembourg had become a major European centre of corporate tax avoidance during his premiership.

Two readings of the same facts are on the table and both are held seriously. The industry's own account, given by Luxembourg for Finance, credits regulatory expertise, political stability, cross-border experience, multilingual staff and a government competitiveness agenda. The critical account, argued by tax researchers and by the historians of the Holding Act, describes a network of lawyers, bankers and political elites that has maintained a tax avoidance infrastructure inside the European market for the better part of a hundred years. The listed factors in the growth of the sector include a tradition of banking secrecy alongside good communications and easy access to other European centres, which is the awkward part of the record for the first reading and the whole of the case for the second.

How a surplus turned into a deficit

Public finances reversed inside a single year. Luxembourg ran a general government surplus of 0.9% of gross domestic product in 2024 and a deficit of 2.0% in 2025, a swing the IMF called sharper than expected. Expenditure rose 8.8% over the year, driven by capital transfers to special funds, higher social benefits and a public wage bill that grew beyond automatic indexation. Revenue rose 2.5%, after annual increases close to 10% in 2023 and 2024. Corporate and personal income tax receipts fell outright, and value added tax was held back by slower consumption.

The stock is still small and the direction is the concern. Gross public debt was 26.5% of gross domestic product in 2025, low by any international comparison, and IMF projections carry it to 28.2% in 2026, 29.8% in 2027 and 32.0% in 2028, without stabilising over the medium term. The deficit is expected to sit near 2% of output in both 2026 and 2027, and to approach 3% if the conflict in the Middle East runs long.

Two reforms account for much of the pressure ahead. The pension reform of 2026 was welcomed by the IMF as timely, with the caveat that more will be needed. The planned move to individual income taxation would reduce the disincentive facing second earners and lift take-home pay, and it is expected to cost around 1% of gross domestic product a year from 2028; taken together with enhanced family and child allowances and the reform of the childcare voucher system, the package adds roughly 1.5% of output to the spending bill. Fund staff recommended containing current spending, broadening the base through property and environmental taxation, and rebuilding a national fiscal rule around a debt anchor. The underlying problem is that the tax base is concentrated: the financial sector's outperformance and a rising labour income share carried recent revenue, and neither is expected to keep doing so.

Why unemployment rose while employment was growing

Employment in Luxembourg grew 1.2% in 2025 and unemployment rose anyway. The number of people out of work went from 18,000 in 2024 to 19,000 in 2025, 6.0% of the labour force on the IMF's measure, and STATEC recorded 6.3% in March 2026. At the start of 2026 the Luxembourg unemployment rate passed the euro area average for the first time on record, in a country whose unemployment is traditionally low and had reached 6.1% by May 2012 after the Great Recession.

The mechanism is the border again. The labour force grew faster than employment because participation rose, and the hiring that did happen was disproportionately of cross-border workers, which adds jobs without subtracting from the resident jobless count. The rebound in cross-border employment reflects a recovery in the non-financial market sector, which had been badly hurt by the crisis in construction. Three quarters of the total employment growth in 2025 came from non-market activities, and STATEC expects the market sector to take over as the main creator of jobs, at 1.7% growth in 2026 and 1.9% in 2027, with unemployment easing only to 6.2% on average in 2027.

What sits underneath is a matching problem rather than a shortage of jobs. The IMF describes persistent skill mismatches in a small economy with rising demand for new skills and a limited domestic supply of people who have them, and recommends prioritising science, technology, engineering, mathematics and information technology in curricula, alongside the reskilling programme introduced by the Skills-Plang bill in 2025. Housing is the other constraint, and it is a labour market constraint as much as a social one: persistently high housing costs weigh on real incomes, on labour supply and on competitiveness, which is why the Fund pushes land taxation to discourage hoarding and a proposed land mobilisation tax rather than more demand-side support. The politics of all this is covered in Luxembourg: politics.

How a war in Iran reaches Luxembourg

The war in Iran began on 28 February 2026 and closed the Strait of Hormuz, and a country that imports oil and gas for most of its energy felt it through prices before anything else. STATEC's central scenario assumed a short conflict and a reopening of the strait in June, and on that basis put growth at 1.2% in 2026 and 1.9% in 2027, with inflation at 2.5% then 1.7%. The IMF, working the same way, projected 1.2% growth in 2026 and 1.7% in 2027, with inflation at 2.6% in 2026. Growth of 0.6% in 2025 was the fourth consecutive year below both the historical average and the euro area result.

The unfavourable scenario is worth stating because the gap between the two is wide. If the war and the blockage run three months longer, STATEC has output falling about 1% in 2026 before rebounding 1.8% in 2027, inflation reaching roughly 4% in 2026 and 2.4% in 2027, an additional wage indexation tranche triggered as early as the third quarter of 2026, and the public deficit approaching 3% of output. Average wage costs already grew 4.4% in 2025 on the back of the May index tranche, and automatic indexation is the channel through which an oil price becomes a domestic cost base.

Energy exposure here has an odd geography. Luxembourg tried to build a 1,200 MW nuclear reactor in 1978 and abandoned it under the threat of mass protest, and the Cattenom plant just over the French border produces more electricity than the whole country consumes, yet direct imports from it are limited by missing infrastructure and by the strength of the domestic anti-nuclear movement. The consolation is that Europe entered this shock in better shape than the one of 2022, having cut gas consumption, diversified supply and built renewable capacity, and that only petroleum product prices have moved so far. STATEC expects greenhouse gas emissions to fall 2% in 2026 and a further 5% in 2027, which would put the country almost exactly on the reduction path its climate law sets, against targets of a 55% emissions cut by 2030 and 49% of cars electric by the same date.
