Sizing UK banking sector’s exposures to local weather coverage related sectors – Financial institution Underground


Giovanni Covi, James Brookes and Charumathi Raja

Local weather transition will undoubtedly expose UK banks to new dangers and alternatives. Therefore, we quantify the UK banking sector’s share of complete belongings allotted in direction of local weather coverage related sectors (CPRS). Utilizing The International Community information set mapping the community of UK banks’ mortgage and safety exposures, we discover that the UK banking system’s direct CPRS exposures quantity as much as 6.1% of complete belongings, or 45.7% of non-financial company (NFC) exposures. When contemplating additionally oblique CPRS exposures in direction of different monetary corporates, the share of complete belongings topic to CPRS classification will increase as much as 10%. Whereas 83% of those belongings are tied up in carbon-intensive sectors, 17% will possible profit from local weather transition plans. We don’t measure exposures topic to climate-related bodily dangers.

Local weather-related transition danger and alternatives

In its first progress report, launched in October 2018, the Community for Greening the Monetary System (NGFS) unanimously concluded that ‘climate-related dangers are a supply of monetary dangers’. Central banks and monetary regulators want to make sure that the monetary system is resilient to those dangers.

In doing so, they need to set key priorities to assemble a framework to evaluate and probably curb climate-related monetary dangers. In line with NGFS, the important thing job in attaining this goal is the disclosure of present exposures within the monetary sector – in different phrases, the creation of a danger map of climate-related monetary dangers.

Nonetheless, the transition in direction of a climate-friendly productive financial system is not going to solely cross by dangers, but in addition alternatives. Subsequently, assessing the trade-off between dangers and alternatives is essential to offering a holistic evaluation on the way forward for the monetary system’s resilience.

Local weather coverage related sectors and the Taxonomy Alignment Coefficient

We comply with Battiston et al (2017) in classifying financial actions into CPRS. This method permits us to evaluate the financial and monetary danger and alternatives that corporations might expertise given a local weather transition, that’s, an financial system reaching net-zero emissions by 2050 as specified within the Paris Settlement. CPRS have been labeled through the use of three fundamental standards: (i) their direct and oblique contribution to greenhouse fuel emissions; (ii) their relevance for local weather coverage implementation; and (iii) their position within the vitality worth chain. The place to begin for this classification is the four-digit NACE classification of financial actions, which is mapped into six fundamental local weather coverage related sectors – fossil fuels, utilities, vitality intensive, buildings, transportation and agriculture. The CPRS classification is thought to be a reference for local weather monetary danger evaluation.

However, to tell apart local weather transition dangers from local weather transition alternatives, we make use of the Taxonomy Alignment Coefficient (TAC) methodology developed by Alessi et al (2019) to quantify the share of banks’ CPRS exposures that could possibly be recognized as ‘inexperienced sectors’, ie these benefiting from the local weather transition.

Large granular information units

To calculate the UK banking system’s publicity to CPRSs, we use the International Community information set, overlaying the UK banking system’s belongings utilizing a granular method. This information set is made up of six supervisory information sources overlaying mortgage, debt and fairness safety exposures in addition to derivatives exposures. In complete, the International Community captures £9.4 trillion of gross exposures out of £10.6 trillion of complete UK belongings in 2021 This autumn, roughly 90% of UK banking system’s belongings. The information set is split into two fundamental units of exposures. The granular element accounts for 43% of complete publicity quantities (£4.1 trillion). When the granular element isn’t accessible, we add aggregated exposures by the counterparty’s nation and sector because the residual element which contributes to 57% of the whole protection (or £5.3 trillion).

For this particular train (Desk 1), we use mortgage and safety exposures to the NFC sector, to seize the dimensions of CPRS exposures. In 2021 This autumn, we now have £1,200 billion UK banks’ exposures, of which 37% of NFC exposures are mapped with granular bank-to-counterparty data. The counterparty identification by way of Authorized Entity Identifiers permits us to affiliate every counterparty with a four-digit NACE code and in flip with a CPRS classification. We additional decompose the exposures into loans and securities. The residual element (63% or £757 billion) has been mapped with aggregated exposures by nation and sector of the counterparty and this classification will likely be used to estimate complete CPRS exposures.

Direct and oblique CPRS exposures

For 2021 This autumn, we calculate that out of £444 billion of granular exposures in direction of the NFC sector, virtually £201 billion had been directed in direction of CPRSs (45%) (Desk 2). On this respect, 83% are prone to be topic to local weather transition danger (RISK CPRS), whereas 17% are prone to profit (TAC CPRS) from the local weather transition. Total, wanting on the composition of CPRS sectors, the ‘Buildings’ sector is essentially the most related CPRS element, accounting for £82.5 billion of complete CPRS granular exposures, out of which £55.5 billion is topic to transition danger, and £27 billion to transition alternatives. The second most related CPRS sector is ‘Fossil Fuels’ with £38.1 billion, adopted by ‘Transport’ with £37.7 billion, out of which £32.8 billion topic to transition danger, and £4.9 billion to transition alternatives and ‘Vitality Intensive’ with £31.3 billion.

We additionally estimate CPRS exposures for the aggregated publicity element, taking as reference the share of CPRS exposures calculated on the granular element for loans and securities. Desk 3 supplies the whole quantity of CPRS exposures (calculated and estimated) for the UK banking sector.

We discover that the UK banking system was uncovered in 2021 This autumn to £546 billion of CPRS exposures, that’s, for six.1% of complete belongings, or 45.7% of complete NFC exposures. On this respect, Desk 3 additionally supplies a comparability with different research within the literature utilizing the identical CPRS methodology, ie EU banking system, EU insurance coverage companies and Austrian banking system. So as to evaluate the outcomes with the EU banking system, we gather proof from EBA (2021) train on EU banks’ mortgage exposures and from Alessi et al (2019) for EU banks’ safety exposures. The protection of the 2 information samples isn’t an identical. The EBA (2021) train covers all EU-27 international locations plus Norway and the UK, however focuses solely on a subsample of banks which account for 50% of EU banks’ exposures. On this respect, we rescale all estimates offered by EBA (2021) by an element of two, thereby assuming that the share of CPRS exposures stays fixed as estimated for the UK banks on mixture publicity quantities. In distinction, Alessi et al (2019)’s train excludes safety exposures from UK banks. On this respect, we increase their estimates with our CPRS estimates on UK banks’ safety exposures. Total, in comparison with the UK banking sector, the EU banking sector’s share of complete belongings uncovered to CPRSs is comparatively larger, shut to eight.5%. 

Desk 3: UK banks’ complete CPRS exposures

We must always nevertheless notice that these estimates seize completely direct exposures in direction of the non-financial company sector, which solely account for 13% of complete UK banks’ exposures. The opposite £3,700 billion or 39% of complete exposures are directed in direction of different credit score establishments and non-bank monetary entities, which fall exterior the scope of the CPRS classification. Therefore, it’s crucial to know the share of CPRS exposures the monetary sector holds with a view to derive additionally an oblique measure of CPRS exposures.

On this respect, by making use of the International Community information set, we’re capable of quantify £528 billion of exposures in direction of EU banks and an extra £314 billion of exposures in direction of EU non-bank monetary companies. By weighting the previous by 8.5% and the latter by 13%, respectively the CPRS share over complete belongings of EU banks and EU insurers, we derive an extra £45 billion and £41 billion of oblique CPRS exposures for the UK banking sectors, resulting in a complete (direct CPRS plus oblique CPRS) of £632 billion or 7% of complete belongings. In the long run by assuming a ten% CPRS share for the remaining £2,858 billion of UK banks’ exposures in direction of monetary sector entities, we find yourself with a complete of £918 billion of CPRS exposures or 10% of complete belongings.

Conclusions and coverage implications

Local weather transition plans convey with it dangers and alternatives for the monetary system that central banks should be alert to. Certainly, there’s a urgent want for central banks, regulators and monetary corporations to speed up their capability to evaluate and handle these dangers as was just lately scoped out by the Financial institution of England’s CBES train.

Complementary to the CBES workout routines, we now have sized UK banks’ direct exposures in response to the CPRS classification, which sum as much as 6.1% of UK banks’ complete belongings in 2021 This autumn. Nonetheless, we now have highlighted that additionally exposures in direction of monetary corporations incorporate a carbon footprint, they usually characterize a big chunk of the UK banking sector’s belongings. On this respect, by contemplating additionally oblique CPRS exposures, UK banks’ complete belongings exposures to CPRS improve additional to 10%, an extra 40%.

The better variety of CPRS reference estimates for the monetary sector and subsectors throughout jurisdictions, the higher researchers and policymakers will have the ability to estimate oblique monetary CPRS exposures, and so assemble a world map of monetary belongings topic to climate-related monetary dangers and alternatives. We hope this research might assist to fill this hole.
