And then there is the opportunity presented by the environment, with more government money going towards funding clean energy or renewables.
A recent Standard & Poor’s Market Intelligence report focused on how governments and industry could - or should be - focusing on bringing green infrastructure financing to the fore, working out how to align green bonds and infrastructure loans so investors can “move more of their money into capital stocks that are liquid and observable”.
A slice, not a panacea
While infrastructure funds or individual stocks can fit well into a portfolio, depending on the investors' risk tolerance and income or growth needs, it is worth remembering this is only a slice of an overall portfolio, not the portfolio itself.
Mr Argent is clear about the risks inherent in any investment, and when it comes to infrastructure, he says: "Of course, the vehicles investors can purchase to gain exposure to the infrastructure theme are typically traded on a secondary market.
"This means market prices may be driven by sentiment rather than underlying fundamentals, and may not be reflective of the true value of the infrastructure assets themselves."
He adds it is generally true, at times of great stress, asset classes trend together regardless of the underlying fundamentals - a glance back 10 years at the financial crisis proves this point.
Therefore, according to Mr Argent: "Investors should be mindful infrastructure is not a panacea in the event of extreme market downturns.
"Nevertheless, an allocation can help reduce overall portfolio volatility and provide an attractive dividend stream for investors seeking relatively high, regular income."
