Merz’s €500bn illusion: Where’s the promised infrastructure?

Berlin pitched the €500 billion package as the domestic pillar of a broader national revival. It was presented as the ultimate fix for Germany’s ageing bridges, railways, and broadband networks, meant to run parallel to the country’s historic defence buildup. However, one year later, experts contend that instead of triggering a significant boost in new investment, the fund has primarily resulted in a complex reshuffling of existing expenditures, raising concerns over its effectiveness and genuine economic impact.

Germany’s €500 billion “Special Fund for Infrastructure and Climate Neutrality” marked one of the most significant fiscal U-turns in modern German politics. Approved in March 2025 alongside relaxed borrowing rules for the military, it was designed to finance supplementary spending on rail, roads, hospitals, energy grids, and digital networks. Although Chancellor Friedrich Merz only took office in May 2025, his coalition oversaw the fund’s crucial first year of implementation, championing it as the essential civilian counterpart to Germany’s renewed security commitments.

So far, the numbers are underwhelming. The Cologne-based German Economic Institute (IW) reports that 86% of the fund utilized in 2025 did not generate additional investment. The ifo Institute in Munich paints an even bleaker picture, estimating that 95% of the debt raised through the fund last year failed to finance genuinely new infrastructure. According to ifo, while borrowing through the fund surged by €24.3 billion, actual federal investment increased by a mere €1.3 billion compared to 2024. This discrepancy strikes at the heart of the fund’s political justification: the promise of “additional” investment for new projects, rather than simply rebranding old expenses.

Critics are not accusing the government of losing the money, but rather of shuffling it around. The IW notes that roughly €12 billion from the fund simply replaced spending that would have otherwise come from the regular federal budget. For example, hospital “transformation costs” were logged as investments, despite acting more like routine operational expenses. Earlier budget analyses revealed a similar pattern in transport and broadband, where regular budget lines were quietly slashed as funds were shifted into the special vehicle, effectively wiping out any net gain.

The government vehemently rejects these accusations. The Finance Ministry argues the fund only became fully operational in October 2025. Nevertheless, €24 billion was disbursed by year’s end, and total federal investment still rose by 17% to roughly €87 billion. Additionally, the ministry notes that Germany’s federal states Länder) only gained access to their share after an administrative agreement in December.

Despite these defences, critics argue the fund’s legal safeguards remain flimsy. A mandated 10% investment rule is measured against the budget plan rather than actual spending. Furthermore, as the Bundestag’s own research service highlighted, the law lacks any enforcement mechanism if final investments fall short, a vulnerability underscored by the IW’s calculation that the actual investment ratio in 2025 was a mere 8.7%. For a fund touted as proof that Germany could modernise domestically while simultaneously bankrolling Chancellor Merz’s promised security buildup, Berlin is now facing a mounting credibility problem.
