The Bank of England has announced it will no longer accept bonds linked to thermal coal as collateral for key loan arrangements, marking a significant victory for climate campaigners. This policy, effective from October, targets one of the most polluting industries by restricting how commercial banks use coal-linked assets when borrowing from the central bank.
Why the Bank of England Is Cracking Down on Thermal Coal
Thermal coal, burned in power plants for electricity, has long been a focus of green activists due to its high carbon emissions. The Bank’s new stance suggests these bonds are now considered too risky for its balance sheet, as the global shift toward renewable energy could devalue them. According to Ellie McLaughlin of Positive Money, this move sends a strong signal to both central banks and financial markets.
Impact on Commercial Banks
Major banks like Barclays, Lloyds, NatWest, and HSBC regularly borrow from the Bank of England to ensure smooth transaction settlements. They must provide collateral, typically bonds, as a guarantee. With the new ban, these banks can no longer use thermal coal bonds, forcing them to reconsider their holdings in this sector. About 150 global financial firms already restrict coal-related business, per Reclaim Finance data.
