Infrastructure Funds in Transition – New Opportunities for Institutional Investors

The expansion of transport networks, energy infrastructure, digitization, and municipal facilities requires significant investment. In addition to public funds, private capital is increasingly gaining importance. In this article, POELLATH fund experts Dr. Jens Steinmüller, Dr. Tobias Lochen, and Dr. Philipp Ahlers examine current regulatory developments that are making infrastructure investments via fund structures more attractive.

Why Infrastructure Investments Are Gaining Importance

Germany and many other European countries face enormous investment needs. Transport routes, energy supply, digital infrastructure, and municipal facilities must be modernized and expanded. Public funding alone is insufficient for this purpose. As a result, institutional investors – such as pension funds, insurance companies, banks, and corporate pension schemes – are coming into sharper focus.

Infrastructure investments are often made through fund structures, which pool capital from numerous investors, enabling access to large-scale projects. At the same time, fund managers must consider complex supervisory and tax requirements.

The Growing Appeal of the German Sondervermögen

The German Sondervermögen (separate asset pool) has gained particular attention due to recent developments in investment tax law. As a contractual fund structure, it can help better align tax and regulatory requirements for certain investors. For fund managers, it opens up new structuring opportunities, especially for cross-border investor structures and investments in infrastructure projects, which often need to reconcile diverse investor interests.

A key consideration is the tax classification. Investors expect tax neutrality – meaning that pooling capital in a fund should not trigger additional tax burdens. Additionally, foreign investors aim to avoid becoming subject to tax reporting obligations in another country solely due to their fund participation. Recent legislative adjustments have created new structuring options and increased the attractiveness of German fund structures.

Infrastructure Quota Creates New Investment Scope

A dedicated infrastructure quota has been introduced for pension funds and corporate pension schemes. It allows up to 5% of the guarantee assets to be specifically allocated to infrastructure investments. This eases pressure on other mixed quotas, which are already largely exhausted for many investors. However, some practical questions remain unresolved, such as the application of the federal infrastructure quota under the state law governing pension funds, and the allocation of individual infrastructure investments within mixed fund portfolios. Further clarification from the supervisory authorities is expected through the revised Kapitalanlagerundschreiben (Capital Investment Circular).

Beyond Equity – The Expanding Role of Infrastructure Debt

Infrastructure financing is no longer limited to traditional equity investments. Fund managers now utilize a broad spectrum of financing instruments, ranging from senior debt and mezzanine capital to hybrid capital and classic equity participations.
For investors, a wide range of options has emerged to more precisely control risk and return profiles. Hybrid structures, in particular, are gaining importance. They combine features of both equity and debt, allowing for flexible structuring of returns, collateral, and control rights. This enables tailored solutions to meet diverse investor needs.

Regulatory Relief for Insurers and Banks

New incentives for infrastructure financing are also emerging at the European level. Insurers and banks can benefit from reduced capital requirements for long-term equity investments in qualified infrastructure projects. Additionally, investments made in conjunction with government programs are gaining significance, as they can provide additional relief from capital requirements under certain conditions.

As a result, infrastructure commitments are becoming more economically attractive for institutional investors. However, this is contingent on the respective projects and fund structures meeting regulatory requirements and the necessary data being available for supervisory assessment.

Open Infrastructure Funds and Professional Liquidity Management

At the same time, demand is growing for semi-liquid funds, particularly evergreen funds and open infrastructure funds. These are designed to offer investors regular entry and exit opportunities, even though the underlying infrastructure investments are long-term and illiquid.

New liquidity management requirements strengthen the stability of such funds. Fund managers must implement appropriate tools to manage redemptions and identify liquidity risks at an early stage. As a result, investors are increasingly focusing on reviewing a fund’s liquidity concept.

Conclusion

The regulatory framework for infrastructure funds is currently undergoing significant development. New fund structures, the introduction of the infrastructure quota, more attractive capital requirements, and new liquidity rules for open funds are creating additional investment incentives. For institutional investors, these changes open up new opportunities to efficiently channel long-term capital into infrastructure projects while better meeting regulatory requirements.
