Magnette Warns of Belgian Budget Black Hole Alternative

Belgium’s public finances are facing a “gigantic budgetary black hole,” according to Paul Magnette, leader of the francophone Socialist Party (PS), who has launched a blistering critique of Prime Minister Bart De Wever’s fiscal policy and proposed an alternative economic strategy centered on investment and wealth taxation.

Speaking on RTBF’s Matin Première program on July 8, Magnette warned that the federal deficit has doubled from approximately €20 billion to €40 billion under the current government, accusing the administration of pursuing austerity at the expense of workers and pensioners. The intervention comes days after the Monitoring Committee published updated projections showing the federal deficit reaching 3.9% of GDP (€25.7 billion) in 2026 and rising to 5.7% of GDP (€44.5 billion) by 2031, with public debt climbing from 107.9% of GDP to 122.6% over the same period.

A Deficit ‘Doubled’ Under De Wever

“It’s no longer an abyss, it’s a gigantic budgetary black hole,” Magnette declared, as quoted by RTBF. He argued that the government’s budget was “based on sand and figures with absolutely no foundation,” pointing to unfulfilled savings projections.

The government must identify €7.7 billion by 2029 to comply with European fiscal rules, according to the Monitoring Committee’s July 6 report. While the administration cites external factors such as the Iran war and global economic slowdown as contributing to the deficit, Magnette dismissed these arguments, noting that the previous PS-participating government had managed crises including the COVID-19 pandemic and the Ukraine war while reducing the deficit to approximately 3%.

“With the socialists, we reduced the deficit to 3%, created 300,000 jobs, lifted 400,000 people out of poverty, and invested massively in the climate transition,” Magnette said. “You see that it’s possible to do things differently.”

Magnette’s €15 Billion Alternative

At the heart of Magnette’s critique is what he describes as a “discourse of no alternative” promoted by the government. “Mr. De Wever keeps saying: there is no alternative, the only possible policy is austerity,” Magnette said. “When everything goes up except wages, when you make billions in savings at the expense of pensioners, you are breaking the economy.”

In response, Magnette has published a booklet titled Prospérité pour tous (Prosperity for All) — a direct rejoinder to Prime Minister De Wever’s economic text — outlining a five-point plan to raise €15 billion without cutting worker or pensioner purchasing power:

• Wealth tax: A 1% tax on fortunes between €5 million and €100 million, and 2% above €100 million, combined with capital gains taxation, estimated to raise €6 billion
• Wage growth: Annual salary increases of 1%, generating €4 billion in additional revenue
• Reduced military spending: Cutting €3 billion from defense procurement
• Energy and bank contributions: €2 billion from increased levies on energy giants and banks
• Stricter corporate aid: €2 billion from tighter oversight of business subsidies

“You see, in less than a minute, I show you that it’s possible to find 15 billion without touching the purchasing power of workers and pensioners,” Magnette said.

He distinguished the PS approach from that of coalition partner Les Engagés, which has proposed progressive wealth taxation starting at €500,000. Magnette argued this would penalize people who “worked hard and invested,” preferring to target ultra-high-net-worth individuals, referencing economist Gabriel Zucman’s proposals.

Political Strategy and PS Refoundation

Magnette’s intervention serves multiple political objectives. With the PS polling near 30% in Wallonia, he is positioning for a potential return to government while seeking to exploit tensions within the governing coalition between the liberal MR and centrist Les Engagés.

The interview came days after the PS held its ideological refoundation congress in Jambes on July 5, where more than 500 militants approved new statutes on ethics, parity, and governance. As reported by La Libre, the party adopted measures on preventing sexist and sexual violence, ethical governance, AI usage guidelines, and mandate training.

“When you are a socialist, you must be exemplary,” Magnette said, adding that the refoundation process will continue into early 2027, with a potential name change still under consideration.

On the possibility of governing with the far-left PTB, Magnette dismissed the question as “purely hypothetical” and “science fiction,” noting that the PTB has written into its statutes that it will not enter regional or federal governments.

What’s Next

The government faces an October 2026 deadline to present a budget that meets EU fiscal requirements, with tensions already evident between coalition partners MR and Les Engagés. Magnette’s alternative proposals are likely to intensify debate over Belgium’s fiscal direction, though analysts caution that his revenue estimates may be optimistic and that wealth tax proposals risk capital flight.

As Belgium’s debt trajectory continues to worsen, the coming months will test whether the governing coalition can hold together — and whether the PS can translate its opposition offensive into electoral gains.
