New diversity in green bonds

Road to net zero has led to expansion in green bonds opportunity set, says AXA IM’s Johann Plé

The green bonds sector is changing. Years of growth have not only brought it into the mainstream but have also delivered a richer, more varied universe for investors. As the world seeks the funds that will finance the energy transition and the road to net zero, we think this diversification will continue and evolve, rewarding those with the know-how to spot potential wrinkles as the opportunity set expands.

Green bonds emerged as a mechanism to drive capital towards projects or businesses that had at their heart the drive to improve environmental outcomes. Initially, and unsurprisingly, much of the activity was government related. In 2015, the market was dominated by quasi-sovereign issuance and stood at about $50bn. In 2022, the $1trn marketplace is now a 50/50 split between sovereign and credit issuers.

Over the last seven years a host of new players have joined the field – the number of issuers now is close to 600. Banks have played a key role and continue to do so, but we have also seen a substantial contribution from many corporate sectors such as real estate, telecoms, autos, chemicals and consumer goods. More and more sectors are seeing the sense of investing in the transition and seeking funds that can help them reduce their exposure to climate change – or maybe adapt to the effects that a transitioning economy may have on demand.

Sovereigns have continued to issue green bonds and new countries join the fray every year. After the UK, Italy and Spain in 2021, Denmark, Canada or Austria have been recent additions as the sustained momentum around net zero helps to drive investment in the sovereign and corporate sectors.

Greater breadth to the market

With the sector widening, there is now a greater breadth of risk profiles on offer. High quality issuers naturally remain a core part of the market, but on the credit side we have seen more subordination from banks and corporates that have issued Tier 2 and hybrid debt.

There have also been some high-yield (HY) players coming to the market. This was difficult for them initially. They tend to be smaller, which amplifies the effect of the additional costs attached to issuing green bonds for the first time. However, this has been a steady dynamic, and right now HY accounts for about 10% of the wider universe – made up of pure HY and subordinated debt from investment grade issuers which is rated as HY.

We have also seen an increasing appetite for green bonds in developing markets. China has clearly been a huge story, with estimates that issuance in 2022 could breach the $100bn mark. This requires us to look very carefully at the sometimes complex nature of the issuance. China has an important role to play in the transition to a net zero economy, and our general view is that major investors should promote a progressive harmonisation of global green bond standards, and in the meantime focus on close analysis of each bond on its own merits.

Much of issuance in China has been on the onshore market, perhaps discouraging to foreign investors – but there remains substantial issuance in dollars and euros. In short, not every green bond issued in China is eligible according to our framework, but there are credible instruments and initiatives that investors can support.

Growing opportunities in emerging markets

And the emerging markets story is not just about China, with India, Indonesia, Chile and others are getting in on the act at both a sovereign and corporate level. We firmly expect this to gather momentum over the years to come. We also think this constitutes an opportunity for investors committed to an environmental strategy as it helps drive the transition in markets that may be playing catch-up, spreading financing for lower-carbon projects and companies to places where the net impact can be greater than in more developed markets.

Transition-related benefits aside, we believe exposure to green bonds in emerging markets can help diversify portfolios. That is the case in terms of risk profiles and potential yield pick-up compared to similarly rated European issuance, underpinning the case for pursuing a more dynamic strategy in green bonds.

The China example is a good warning for green bond investors that can be applied more widely – not all issuance is created equal. There are risks in this market that may not be visible elsewhere. Is a project actually green, is it aligned with the wider corporate strategy, and how much of capital could be used for ‘other’ purposes?

As the market expands, and breaks new ground, we think we have a responsibility to maintain the integrity of our strategies. Caution is crucial. There is no guarantee that every new issue is genuinely and verifiably ‘green’, and part of the role of a truly responsible and active investor is to carefully interrogate prospective holdings.

Investors need to be diligent

The growth of green bonds is a healthy development, and it is funnelling money to initiatives that will help drive the energy transition, but it also opens up the prospect of companies or countries attempting to come to market with proposals that are not green.

It is therefore vital that a framework is applied when building portfolios. As we diversify holdings into the green bonds space, there has also been an increase in how much issuance we view as falling short of our standards, in both credit and sovereigns.

With diversification comes the need for diligence. The development of the now $1trn green bond market into a truly expansive universe should bring great benefits to the planet – and to active, responsible investors with the wherewithal to understand and navigate the new landscape.
