The Belgian state has historically been protective of institutions it considers central to the functioning of the country, and few qualify more than Belfius, the Brussels-based bank and insurer that quietly underpins much of Belgian public and civic life.
The above fact makes the government’s current plan to sell a 20% stake in Belfius, through a private transaction worth roughly 2 billion euros, all the more significant. To understand why this is happening, and what it means, it helps to go back to where Belfius came from.
Bank Born Out of Crisis
The Belfius story begins not with a founding but with a rescue. In 2011, the Franco-Belgian banking group Dexia collapsed under the weight of bad investments and a crisis of confidence that had been building since the 2008 global financial meltdown.
Dexia had grown by lending vast sums to municipalities and public bodies across Europe, borrowing cheaply on short-term markets to fund long-term loans. When those short-term funding markets froze, the entire structure came apart. The Belgian state stepped in and purchased Dexia’s Belgian banking arm for 4 billion euros, ensuring continuity of service and financial stability.
The new institution was rebranded Belfius in 2012. This was meant to be a bank that belonged to Belgium and could be relied upon. Wholly state-owned, Belfius is focused on serving domestic customers across retail, self-employed professionals, small and medium-sized enterprises, public institutions, and corporate clients.
It is Belgium’s third-largest bank by assets and holds a leading position in public sector financing, serving approximately 50% of Belgian companies through its commercial operations.
What Belfius Has Done for Belgium
In the years since its creation, Belfius has served two distinct but overlapping roles. The first is as a conventional retail bank for ordinary Belgians, handling savings, mortgages, insurance, and everyday banking. The second, and arguably more important, is as the financial backbone of Belgian public life.
With over 23.7 billion euros in outstanding loans to the public and social sector, Belfius finances hospitals, schools, swimming pools, and other public infrastructure across the country. In practical terms, this means that when a Belgian municipality needs to build a school, or a hospital needs to upgrade its facilities, Belfius is typically the institution providing the money.
This role was tested during the Covid-19 pandemic, when Belfius went beyond what its market share would ordinarily require. During the crisis, Belfius provided necessary liquidity and granted deferred payments for companies and SMEs in temporary difficulties.
Nearly 24,000 company loans worth 4.7 billion euros benefited from deferred payments, along with 13,840 lease contracts worth 870 million euros. Belfius also granted Covid credits with state guarantees totalling 509 million euros to companies and the public sector.
As a 100% Belgian bank and insurer, Belfius reinjects virtually all of its customers’ deposits back into Belgian society and the economy. In 2024 alone, it provided 23.4 billion euros in new long-term financing to support all segments of Belgian society. This includes co-financing 52,500 social housing units with solar panels in Flanders and equipping more than 1,000 schools across Wallonia and Brussels with renewable energy installations.
For the Belgian state, the investment has been a financial success beyond simply preserving stability. The state’s return was already positive thanks to dividends paid since the acquisition, with Belfius distributing 1.5 billion euros in dividends in the past two years alone.
That is a considerable return on an original purchase price of four billion euros, and does not account for the value of stability that came from avoiding a disorderly collapse of Dexia’s Belgian operations during the 2011 crisis.
Why Belgium Needs the Money Now
Belgium had a public debt-to-GDP ratio of around 105% at the end of 2024, placing it among the most indebted countries in the European Union alongside France and Italy. At the same time, the country’s budget deficit has been widening.
In 2025, Belgium’s general government deficit rose to 5.2% of GDP, up from 4.4% in 2024, driven by a sharp decline in revenues from income and wealth taxes combined with higher spending on defence and social benefits. That deficit level sits well above the 3% cap that the European Union’s fiscal rules require.
Layered on top of this is the rising cost of defence. For years, Belgium was one of NATO’s chronic underperformers on military spending, consistently falling below the alliance’s 2% of GDP target. Five years ago, Belgium spent just 1% of its GDP on defence. In 2024 this had risen to 1.27%.
The country finally met the 2% benchmark in 2025, for the first time in its history. That required an acceleration of spending. The Belgian government accelerated defence expenditure by four billion euros in the months leading to the NATO summit, taking total defence spending to 2% of GDP.
Under considerable pressure from US President Donald Trump, NATO allies agreed to raise their defence and security-related expenditure to 5% of GDP by 2035. Belgium, which only just crossed 2%, now faces a trajectory that will demand sustained and substantial spending increases for a decade. Belgium already recorded the sharpest increase in defence spending in Europe in 2025, with expenditure rising by 59% to 14.5 billion US dollars.
Spending more on defence while also trying to bring a large deficit under control creates an obvious problem. Something has to give, or new revenues have to be found. Selling a stake in Belfius is one way of finding them.
Why a Private Sale?
An initial public offering (IPO), which would involve listing Belfius shares on a stock exchange for any investor to buy, had been discussed for years. It was previously considered and then shelved during periods of market turbulence.
Finance Minister Jan Jambon told lawmakers that an IPO is a longer process that is more complex and more dependent on market conditions, and that the current period of market instability and volatility made that approach unsuitable.
The private placement route means finding one or a small number of institutional investors to take the 20% stake through direct negotiation. It is faster, more controllable, and less vulnerable to the kind of day-to-day swings in investor sentiment that can derail a public listing. The 20% stake is estimated to be worth about 2 billion euros, or around 2.3 billion US dollars, based on a total bank valuation of approximately 10 billion euros.
Amsterdam-listed private equity fund CVC, along with banks including ING, Rabobank, and Credit Agricole, have been reported as potential interested parties. A smaller stake could offer strategic bidders a lower-risk way to deepen ties in Belgium and potentially set up future cooperation. Jambon acknowledged CVC’s reported interest as a positive signal.
As per the government, the goal is to attract a private investor with the necessary experience who can actively contribute to Belfius’s strategy and business plan. This is not a pure asset disposal. Brussels wants a partner who will add operational and strategic value, not simply a passive shareholder collecting dividends.
What Belgium Gets Out of This
Two billion euros is a meaningful injection at a moment when Belgium needs to fund defence spending commitments while also demonstrating to Brussels that it is serious about fiscal discipline. It does not solve the structural deficit problem, but it buys time and demonstrates a willingness to use state assets responsibly.
The longer-term gain is strategic. By keeping 80% of Belfius in state hands, Belgium retains full control over the bank’s direction and its continued role in public sector financing. This is not privatisation in any real sense. It is the careful introduction of a minority private partner into an institution that will remain, fundamentally, a public one.
The government has been careful to signal that Belfius’s core mission, financing hospitals, local authorities, schools, and the broader fabric of Belgian civic life, will not be compromised by this transaction.
The coming months will determine the final price and the identity of the buyer, and with them, the next chapter of one of Europe’s most unusual banking institutions. A bank built from the rubble of a crisis, owned entirely by its own citizens, is now cautiously opening its doors to outside capital for the first time.
