Summary
Stichting Pensioenfonds Mars, a €1.5 billion Dutch pension fund serving approximately 4,500 members, has nearly doubled its hedge fund allocation to 21% from 11% during 2025, according to its latest annual report cited by IPE.com. The increased exposure was achieved through expanded investments in two existing funds-of-funds, reflecting a deliberate portfolio shift designed to enhance downside protection and stabilize the scheme ahead of its transition to a defined contribution system.
The hedge fund increase formed part of a comprehensive de-risking strategy that significantly reduced the fund's exposure to volatile public markets. Listed equity allocations fell to 5% from 14%, while high-yield bond exposure contracted to 4% from 7%, and emerging market debt dropped to 4% from 11%. These reductions underscore Mars' move away from traditional growth assets toward more defensive positioning. Complementing this shift, the fund established a new passive mandate focused on investment-grade government and corporate bonds, selected specifically for their relative insensitivity to equity and credit market fluctuations.
The strategic reallocation was driven primarily by the fund's objective to protect its funding position ahead of its planned transition to DC status, originally scheduled for an earlier date but now postponed to January 1, 2028. Investment manager and board member Rianne Steenbergen stated that the portfolio had been deliberately structured to withstand financial-market shocks and preserve the funding ratio during this transition period. At end-July, Mars' funding ratio stood at a healthy 138%, providing a cushion for the conversion process.
The portfolio changes reflect Mars' longstanding conviction that alternative investments, including hedge funds and private equity, provide valuable diversification benefits and access to illiquidity premiums. By increasing hedge fund exposure while reducing public market volatility, the fund is pursuing a more balanced risk profile designed to navigate both market uncertainty and the administrative requirements of converting to a DC framework.
