Infrastructure is stronger than ever amid the current macroeconomic risks, and investors will see greater opportunities in the asset class amid the world's population growth and rapid urbanization, said Irene Mavroyannis, real asset advisory firm Sera Global's global head of the private capital advisory, practice for infrastructure, renewables and sustainable investing.In ASK 2022, The Korea Economic Daily's biannual forum on alternative investment, Mavroyannis introduced the reasons why infrastructure stands out now more than other asset classes. She explained the characteristics of infrastructure as three “R”s: Resilience; long-Run investing horizon; and attractive risk-adjusted Returns.Firstly, infrastructure has low elasticity of demand and high barriers to market entry, which protect pricing power and makes the asset class resilient during COVID-19. Also, infrastructure can generate stable cash flows based on long-term contracts and is more resistant to short-term market volatility. In addition, infrastructure has provided better absolute and risk-adjusted returns than traditional assets across varying market conditions and regions, the global head of private capital advisory said.She also picked some key takeaways from the infrastructure investment amid rate hikes, inflation, climate change and demographic trends.Rising interest rates place pressure on asset valuations, especially for long-duration assets such as infrastructure. However, historical data demonstrates that infrastructure outperforms amid interest rate hikes. Despite the higher discount rate due to rate hikes, rising inflation and earnings benefit from gross domestic product (GDP) growth increase asset price and cash flows. This indicates the earnings benefit is a greater positive for asset prices than a higher discount rate is negative, Mavroyannis said. Also, infrastructure has shown great performances amid higher inflations, generating positive absolute returns as well as high profits in equities and bonds, as the asset class' cash flow is linked to inflation. Even in a high inflationary environment when growth is below average, infrastructure still outperforms due to its defensive qualities, she added.In addition, decarbonization provides greater infrastructure investment opportunities. The global net-zero activities require radical reform of infrastructure frameworks, including decarbonization of existing assets and the creation of carbon-neutral replacements. Hence, global momentum to adapt and respond to climate change will create significant investment opportunities in infrastructure, she said.Lastly, the world's growing middle class is accelerating urbanization and technological innovations which drive expansion in global infrastructure. World Bank has reported that 4.2 billion people, more than half of the global population, are living in urban areas and the number will rise to 6.6 billion by 2050. The speed and scale of urbanization need huge expansion of infrastructure, with approximately $3.7 trillion of injection in the asset class every year. There will be also a need for digital infrastructure frameworks with increasing investment opportunities, Mavroyannis added.
