Regulated financial investors, such as banks or insurers, invest into infrastructure assets for various reasons, such as diversification, stable cashflows or excess returns through illiquidity premiums. At the same time, those investor groups are subject to extensive and dynamic regulatory frameworks, such as Solvency II or CRR I/II. Recent developments in the area of sustainable finance/ESG, as well as COVID-19, are also covered by the regulations. GPs aiming to raise funds from regulated LPs need to understand how those requirements are interconnected and optimize them accordingly.
