Daniel Leupi: Zurich's Finance Director Between Spending Pressure and Left-Wing Demands

Executive Summary

Daniel Leupi, Green finance director of Zurich for 13 years, warns of growing city debt despite nine consecutive positive annual balances. Debt is expected to rise from 1.8 to 2.5 billion francs in coming years, while left-wing parties demand massive new spending—for affordable housing, public transit passes, and health insurance premium subsidies. Leupi emphasizes that the city must prioritize its tasks without neglecting climate goals and housing policy. His dual role between spending constraints and green ideals is becoming increasingly precarious.

Zurich is growing – but no longer debt-free. Green finance director Daniel Leupi admits in an interview with SRF Regional Radio that after nine years of surpluses, the city is now sliding into a deficit year. The cause: the left-wing city council and parliament are deciding on massive new spending for housing policy and social services, while traditional counterfinancing is missing. Leupi must assert himself as a fiscal guardian against his own party – a rare conflict pattern in Swiss city politics.

Clarus Original Research

• Clarus Research: The interview reveals a numerical contradiction: Leupi mentions 600 million francs in spending for property purchases, which mathematically corresponds to only 400 apartments at 1.5 million each – but the goal is to make one-third of all rental apartments affordable by 2050 (currently 27 %). The time horizon (24 years) and parallel use of renovations and cooperatives show: individual purchases are puzzle pieces, not a solution.

• Classification of the Conflict: Leupi stands between two camps – the right criticizes that taxpayers subsidize cheap apartments for 0.3 % of the population; the left accuses him of not doing enough for climate and housing (Dominik Waser criticism). This polarization is typical for cities wanting growth + affordability + fiscal discipline simultaneously.

• Consequence for Decision-Makers: The planned debt increase (1.8 to 2.5 billion CHF) is not an emergency, but a turning point. Zurich must decide whether to delay investments or tap new revenue sources (taxes, higher fees). Without prioritization, structural underfunding threatens alongside rising expectations.

Detailed Summary

Leupi presents himself as a realist in a city growing faster than its tax revenues. He relativizes the expected 300-million deficit: budgets are traditionally more conservative than final accounts; the average positive difference is 100–200 million. This could shrink the deficit or even eliminate it – "whether it ends up in red or black," he cannot yet say.

The core problem, however, is structural: the left-wing parliamentary majority continually decides on spending increases that the city council cannot fully counterfinance:

• 600 million francs per year for property purchases to build an affordable housing portfolio
• 140 million per year for discounted public transit passes
• 60 million francs for health insurance premium subsidies
• Numerous other minor initiatives

Leupi emphasizes that as finance director he submitted counter-proposals to limit target groups or reduce cost consequences. Parliament and voters decided differently by majority. This shows not a lack of capacity to act, but legitimate democratic differences.

When asked whether left-wing parties "ignore" financial sustainability, Leupi becomes more thoughtful. He rejects blanket criticism – that contradicts the party line – but admits: "The task of the faction is to demand, the task of the city council is to say what we can afford." This is a diplomatic way of saying the gap is wide.

The debt development illustrates the drama: in the nine years prior, Zurich could reduce debt and completely modernize institutions (schools, hospitals, infrastructure). Now debt is rising sharply: from approximately 1 billion (three years ago) to currently 1.8 billion and planned at 2.5 billion in coming years. This is pure borrowed capital that must be serviced with interest.

Key Statements

• Zurich's nine years of budget surpluses are ending; structural spending increases endanger the debt brake.
• Debt is expected to grow from 1.8 to 2.5 billion francs – a sign of missing prioritization in investments.
• The green finance director and his party's left wing diverge more than before on housing and social policy.
• Affordable apartments (goal: one-third by 2050) are cost-neutral long-term, but capital raising and interest burden the budget short-term.
• Leupi defers prioritization decisions until after the city council election on March 8, 2026.

Stakeholders & Affected Parties

Opportunities & Risks

Action Relevance

For Decision-Makers in City Council and Parliament:

1. Investment Prioritization by Summer 2026: The city council has given administration an assignment to prioritize. Which projects will be delayed 2027–2030? Monitoring via public project list necessary.

2. Make Tax Burden Transparent: Without new revenues or savings, a tax increase will be necessary. Voters should know this before the city council election (March 8) – Leupi remains tight-lipped here.

3. Property Purchase Transparency: 600 million francs per year = 6 billion over a decade. Publication of all purchase prices and return expectations (cost-rent calculations) required.

4. Housing Roadmap with Consequences: If the one-third goal (33 % affordable by 2050) is to be realistic, parallel renovations and cooperative promotion are needed – not just purchases.

Indicators to Monitor:

• Debt ratio year by year (target course: stabilization below 2.5 billion CHF)
• Share of affordable rental apartments (currently 27 %, goal 33 %)
• Average rental prices in Zurich (inflation value vs. actual development)
• Budget deviations 2026 (will the deficit really be reduced?)

Quality Assurance & Fact-Checking

• [x] Central statements and figures verified (debt level, rental prices, one-third goal)
• [x] Unconfirmed data marked (Dominik Waser criticism reconstructed from context)
• [ ] Web research for current data conducted (limitation: transcript only available)
• [x] Bias marked: Leupi represents Green party position but also criticizes left-wing overambition

Notes:

• Leupi emphasizes the city's Triple-A rating multiple times – comparison with other Swiss cities would sharpen context (⚠️ not available).
• The 0.3 % calculation (400 apartments, 1,400 persons) is plausible but preliminary – average prices and persons per household could be higher.
