To finance an environmentally-friendly project, firms can opt to issue green bonds. This study finds that investors are willing to accept slightly lower yields on green bonds. However, this premium (or “greenium”) fluctuates over time, and varies according to euro area country, sector and the green label obtained.

As France undergoes the transition to a low-carbon economy, the financial sector must manage the associated risks and contribute to its financing. The sector's exposure to climate transition risk is far from negligible, while securities and loan portfolios are still not adequately aligned with European low-carbon transition targets.

-- Quoted by Agefi (Link 1 & 2), AFP & L'info durable (Link).
Investment funds are exposed to the risks associated with climate change, and especially to transition risks. There are two possible channels of transmission: a fall in the value of the financial assets in fund portfolios (notably “brown assets” which are those issued by companies carrying out activities that are bad for the climate); and investor outflows caused by changes in investor behaviour in response to climate challenges. French funds steadily sold off certain types of brown assets between 2011 and late 2022, and appear to be less exposed to climate risks than their European peers. However, climate risks remain significant and still pose a threat to numerous funds, as an average of 24% of portfolio assets were still brown at the end of 2022. This relatively high share of brown assets also affects the climate risk exposure of financial actors holding shares in these funds (e.g. insurers).

The Russian invasion of Ukraine led to a change in the structure of interconnections between financial markets. While the contagion effects have remained limited overall, the war has brought about new negative correlations between certain commodity indices (aluminium, oil, gold, silver, wheat) on the one hand, and equity markets, particularly in Europe, on the other.

Given the recent outperformance of those sectors best-positioned to accompany the ecological transition, some commentators have voiced fears that a bubble might be emerging in “green” equities. A systematic analysis based on the environmental scores (the “E “in ESG) of over 2,500 stocks in the Datastream Global Equity Index suggests that these fears may be overdone.
