The new head of the Dutch Central Bank thinks the world’s AI spending spree is going to push prices up before it brings them down. Olaf Sleijpen, who took the helm at De Nederlandsche Bank on July 1, 2025, has been making the case that the billions pouring into artificial intelligence will create near-term inflationary pressure, but that future productivity gains should eventually offset the damage.

It’s a nuanced take from a central banker who also sits on the ECB Governing Council, and it matters because the eurozone is still trying to thread the needle between growth and price stability.

The inflation balancing act

The OECD and Bank for International Settlements estimated that global AI investments exceeded $150 billion in 2023. That figure represented a modest share of global GDP at the time, but the trajectory has been sharply upward since.

For central banks trying to manage inflation expectations, this creates an awkward timing problem. The spending hits the economy now, while the productivity gains arrive on a delayed schedule that nobody can precisely forecast.

Bubble warnings and financial stability concerns

DNB’s autumn 2025 financial stability report flagged concerns about elevated US stock valuations driven by AI optimism.

By May 27, 2026, Sleijpen had gone further, labeling generative AI as a pressing threat to financial systems. Not because the technology itself is dangerous, but because its capabilities can expose vulnerabilities in financial infrastructure and because the market dynamics around it are creating concentration risk.

As of June 2026, DNB was actively warning about potential AI-driven investment bubbles. The central bank has been monitoring these dynamics alongside other macro concerns like the energy transition and geopolitical instability.

Sleijpen also articulated concerns about cyber risks linked to AI systems in 2026.

What this means for investors

In the near term, Sleijpen’s framework suggests that central banks in the eurozone may be reluctant to cut rates aggressively if AI-related spending is adding to inflationary pressure. If the ECB holds rates higher for longer because of AI-driven demand, that creates a tighter liquidity environment for speculative assets.

The ECB has already shown willingness to regulate digital assets through MiCA. Adding AI-related risk considerations to that regulatory toolkit would not be surprising.

For traders, the actionable takeaway is to watch ECB communications closely for any indication that AI-related spending is being factored into inflation forecasts. If Sleijpen’s view gains traction among other Governing Council members, it could shape rate decisions in ways that aren’t fully priced into markets yet.
