Climate Risk Measurement & Management Flashcards
Understanding transition risk requires sold data on…
- GHGs attributable to an asset / firm
- Understanding of the policy landscape
- Understanding of technological changes
- Understanding of consumer and broader societal preferences
Risk metrics for Operational Risk
Proportion of facilities exposed to climate risks
Level of preparedness / resilience
Micro level operational risks
Macro level operational risks
Micro:
- physical - weather events disrupt premises / supply chains
- transition - abrupt policy changes cause shutdowns
Macro:
Only in specific circumstances i.e. geographic concentrations
Credit Risk Metrics
PD, LGD, EAD
Credit Risk Micro and Macro level
Micro:
- physical - property damage and business interruption impacts revenue and profits
- transition - asset stranding can worsen firms position (increasing PD & LGD)
Macro:
Significant, sector wide asset stranding potential
Liquidity Risk Climate Metrics
Loan to Deposit Ratio
Liquidity Ratios
Bid Ask Spread
Liquidity Risk Micro & Macro
Micro:
Abrupt events can prompt sharp repricing and evaluation of firm viability
Macro:
Significant, Climate ‘Minsky Moment’ could cause widespread repricing
Underwriting / Insurance Climate Metrics
Change in insurance premiums
Availability
Underwriting / Insurance Micro & Macro
Micro:
- physical - higher in vulnerable areas, many may no longer afford
- transition - less availability & some areas may be refused underwriting
Macro:
Significant - number of insurers withdraw or refuse coverage, some firms will be left without
Market Risk Climate Metrics
Weighted Average Carbon Intensity
Carbon VaR
Portfolio Risk Scores
Market Climate Risk - Micro & Macro
Micro:
Incorporated through asset prices, shifts in asset prices increase risk on FI portfolios.
Macro:
Mixed - countries have diversified economies and geographies.
Impacts to LGDs are likely to be…
High sector specific
Explain how asset stranding impacts credit risk
Company’s core assets fall in value or become worthless
With less valuable assets, a company’s liabilities weigh heavier on balance sheets
More likely that company will default on future debts given company has less collateral
Explain pricing effects
Markets for inputs (raw materials) and outputs (products) may be impacted if raw materials become more $$$ or makes products less valuable
Industry is internalising the link between credit risk and sustainability performance…this can be evidenced through
The risk in sustainability linked bonds and loans
How does a loan to deposit ratio increase due to climate?
Climate drivers may prompt depositors to draw down deposits
& debtors to draw down credit lines at the same time
I.e. post natural disasters
Liquidity risk only manifests as a consequence of climate risk under specific circumstances -
An acute climate related event or imposed authority fines for non-compliance
Which is more gradual credit or liquidity
Credit more gradual
Liquidity more abrupt
Whom does underwriting risk directly impact?
Only the insurance sector
However many corporations and FIs rely on insurance coverage
Insurance coverage works best when
Large pool of participants have small and close to equal change of being stuck by misfortune, when these accidents follow predictable patterns
An 18% probability of occurrence is the same as a return period of ___
5.5 years
Hurricane Harvey’s annual probability of occurrence
1980s vs 2010s
1% vs 6%
Difference between larger insurers and smaller regional insurers
Larger insurers have more diversified exposure and can cross-subsidise to an extent
Smaller, regional insurers without geographic diversity don’t have this luxury
The REPRICING effect occurs through market risk transmission channels…
Define the repricing effect and how it occurs
Repricing effects occur where climate risks are anticipated to impact prices, but these risks have not yet been baked into asset prices. Repricing effect have a quicker impact on asset prices.
What is the main concern within market risk?
How is this reflected?
Increased volatility -
Reflected in Climate VaR
How is standard VaR calculated?
Estimated P&L probability density curve of an investment / portfolio
Then look at the lowest 5% of the distribution to estimate tail risk
+ / - of VaR
+ useful due to cross comparability across different types of investments
- sensitive to the data used to construct it (i.e. if constructed from low volatility period, distribution may be optimistic)
Which sectors are those most exposed to a combination of physical and transition risk according to Climate VaR?
Construction
Coal
Electrical Utilities
It is possible that climate risk can lead to a breakdown of typical correlation patterns between assets.
What does this mean?
That the effectiveness of hedges and banks abilities to actively manage their risk may be reduced
What does empirical evidence suggest about climate risk and asset prices?
Majority suggests that climate risk is yet to be priced into many asset classes yet
What is a reason why repricing due to climate risk has been limited thus far?
Inefficiency and insufficiency of governments and companies in reaching commitments such as the 2*c PCA
What does the PRI’s ‘Inevitable Policy Response’ assume?
As the realities of climate become more urgent, governments and others will be forced to act more decidedly in quite a rapid, abrupt and disorderly way
