Green bonds trade less often than corporate bonds in general and tend to yield about 0.04 percentage point less. If many investors decide to liquidate their holdings, they may be disappointed by demand in the secondary market. Bank of England will likely cut its target for corporate bond purchases in the energy sector as it implements measures to greenify QE.

Energy analysts argue that the European Union moved too quickly away from fossil-fueled power, before ensuring that sufficient renewable sources could take up the slack in an emergency. Caught halfway in a transition that should take decades, they say, Europe is now scrambling to find coal and gas to burn in its remaining traditional power stations.

Spain has called for a change to the EU’s marginal pricing system and for a common EU approach, including natural gas purchases and strategic reserves. It has pushed back against electricity companies’ challenge to Madrid’s €3bn levy on their “windfall profits”. Some EU leaders are calling for the bloc to reconsider decarbonisation plans.

“The short-term prices are the only price signals for long-term investment and this has to change,” said the CEO of nuclear power giant Electricite de France SA. He also urged EU nations to overcome their divisions concerning nuclear power when setting the financial rules, otherwise, only non-European banks will be able to finance new atomic plants.

The EU wants to become the first climate-neutral continent by 2050. That will not work without massive government investments and subsidies. The EU's “Green Deal” is the conceptual basis for this change. Indirectly, the state's policy will also trigger price inflation in “green” stocks. Green price bubbles could emerge at some point in the 2020s.

Banks have earned about $3.6 billion in fees in 2021 from arranging sales of ESG bonds for companies and governments. That is more than double the $1.6 billion banks pocketed so far this year from issuing debt for fossil-fuel companies. About $750 billion of ESG bonds have been issued this year, compared with $468 billion during all of 2020.

Institutional investors rushed to buy the UK’s first green sovereign bond with a 0.87% yield. The government will launch Green Savings Bonds through the national savings scheme. If it offered the “market-leading rate” for retail savings of 1.8%, the scheme would cost taxpayers £210m per year. Setting the rates lower could look unattractive to customers.

Wind farms were paid £1.85 million to shut down this week – at a time when consumers face huge rises in energy bills because of the spiralling cost of natural gas. The turbines were switched off, because the electricity they would have produced could not have reached the regions that needed it. Instead, electricity from gas-fired power stations was used.

On-demand power from storage is critical for preventing blackouts in Australia, which is increasingly dependent on wind and solar farms, from which energy is not always available. Hornsdale Power Reserve was called on to dispatch power in July to November 2019 during frequency disturbances, but that the energy was not supplied as needed.

Europe’s gas prices have more than tripled this year as top supplier Russia has been curbing the additional deliveries the continent needs to refill its depleted storage. Higher gas prices boosted the cost of producing electricity. Europe is short of gas and coal and if the wind doesn’t blow, the worst-case scenario could play out: widespread blackouts.

Global debt rose to a new record high of nearly $300 trillion in the second quarter of 2021. China has seen a steeper rise in its debt levels compared with other countries, while emerging-market debt excluding China rose to a fresh record high at $36 trillion. Debt among developed economies, especially the euro area, rose again in the second quarter.

Italy’s power prices are set to increase by 40% in the third quarter as a global natural gas supply crunch starts to impact the country ahead of the cold season. The increase is part of a rally across Europe that’s set to boost bills for consumers all over the continent. Coal reserves in European ports are also at the lowest level for this time of year since 2016.
