European CFOs must adjust as the region’s biggest pension buyer of long-dated debt cuts back.

The Netherlands pension system is beginning to reduce one of Europe’s most reliable sources of demand for long-dated debt as a broad regulatory shift changes how Dutch pension funds manage their assets and liabilities. ING Groep NV estimates that nearly €600 billion ($699 billion) of assets have already been affected by the change, with more than €900 billion expected to follow early next year.
Under the old defined-benefit pension system, Dutch funds were required to hedge the interest-rate sensitivity of long-term pension liabilities by using long-dated bonds and swaps to match assets with payments extending decades into the future. Under the new defined-contribution model, which became law in 2023, that liability matching requirement has been significantly reduced, allowing funds to carry less duration and scale back their long-term hedges, resulting in less structural demand for the longest-dated debt and swaps.
For European CFOs, this could mean a higher premium for 20-, 30- and 50-year borrowing as companies and governments compete for a smaller pool of long-duration investors.
The change “should reduce structural demand for long-end duration assets and support curve steepeners over the long-term horizon,” wrote Sara Adjir, senior vice president and portfolio manager, and Jeroen van Bezooijen, account manager, at Pacific Investment Management Co., in a research note . They expect the impact will be mostly concentrated in 50-year swaps, but will also be felt in the demand for 20- and 30-year euro swaps and government bonds, including German and Dutch debt.
The Netherlands runs Europe’s largest pension system, with roughly €1.6 trillion in assets, and every fund must complete the switch by January 2028. Dutch pensions have long dominated the market for European long-dated debt, holding around €88 billion of interest-rate swaps maturing beyond 25 years at the end of last year, roughly a quarter of the total.
The first major wave of the transition came on Jan. 1, when 24 funds converted, among them the healthcare scheme PFZW and the metals scheme PMT, with an estimated €550 billion to €600 billion of pension assets between them. Analysis by the Netherlands central bank shows that Dutch pensions bought almost €34 billion net of swaps maturing inside 25 years while selling more than €12 billion of longer-dated ones.
The bigger test, however, comes when more than €900 billion of pension assets is scheduled to convert on Jan. 1, with the Dutch civil service scheme ABP accounting for about €530 billion of that.
The shift does not mean long-dated Dutch debt is suddenly becoming illiquid or even hard to sell: “Overall, we still see strong demand for our 30-year bond. Remember, we are AAA,” said Saskia van Dun, director of the Dutch State Treasury Agency.
Data indicates that sovereign borrowers are already adjusting to the change.
The share of Netherlands government bonds sold at maturities beyond 10 years fell from 42% at the start of 2025 to 31% by the third quarter, according to the Organization for Economic Co-operation and Development (OECD), which calls the constraint on long tenors structural. The OECD expects euroz…
