9 Bank risk management Flashcards
Four main functions of a bank
1) accepting deposits
2) granting loans
3) providing payments
4) providing maturity transformation
What’s the aim of bank’s management?
▪ To manage a bank with the goal of maximising its value for shareholders under risk conditions
▪ Information asymmetry
▪ Appropriate risk management needed
▪ Corporate governance/principal-agent problem
Definition of risk
▪ Risk is …the degree of uncertainty of future net returns.
▪ The basic measurement tool is the volatility (standard deviation of price associated with an underlying asset).
Risk NEVER disappears!
Derivatives help create the illusion that risk can disappear!
Categorization of risks in banking
- Financial risks
- Non-financial risks
Financial risks
▪ credit risk 60-80%
▪ market risk 5-15%
(interest rate risk, FX risk, equity risk, commodity risk)
▪ liquidity risk
Non-financial risks
▪ operational
▪ legal
▪ taxes
▪ regulatory
▪ political
▪ reputational
▪ systemic
risks that are more difficult to quatify
- Market risk (the less difficult)
- Credit risk
- Liquidity risk
- Operational risk
- Political risk
- Legal and regulation risk (the most difficult)
Credit risk
▪ = risk to the bank of losses resulting from the failure of a counterparty to meet its obligations in accordance with the terms of a contract under which the bank has become a creditor of the counterparty,
▪ Credit risk represents 60-80% of all banking risks.
Market risk
▪ = risk to the bank of losses resulting from changes in prices, exchange rates and interest rates on the financial markets. This is a summary term for interest rate risk, foreign exchange risk, equity risk and other risk associated with movements in market prices,
▪ Very roughly, 5–15% of all banking risks are accounted for as market risks.
Operational risk
▪ = risk to the bank of loss resulting from inadequate or failed internal processes, people and systems, or the risk to the bank of loss resulting from external events, including the legal risk but it excludes strategic and reputational risk.
▪ Operational risk represents 5–20% of banking risks, depending also on the extent to which it overlaps with the definition of other risks (especially credit risk).

rare event with severe impact => tail events (challenging
for bank risk management)
Liquidity risk
▪ Liquidity risk is the probability of a situation when a bank cannot meet its proper (both cash and payment) obligations as they become due or the bank will not be able to fund its assets,
▪ Potential loss due to insufficient market depth
▪ Liquidity risk arises from the different timing of the cash flows of assets and liabilities, i.e. liquidity risk arises from positive maturity transformation provided by banks
▪ No capital requirement on liquidity risk is needed since liquidity is measured differently (in Basel III: Long-term Coverage Ratio (LCR), Net Stable Funding Ratio (NSFR))
▪ Banks seek liquidity (quick assets) to cover the need to withdraw deposits and to grant the loans of clients.
Systemic risk
▪ Systemic risk = the risk of widespread disruption to the provision of financial services that is caused by an impairment of all or parts of the financial system, which can cause serious negative consequences for the real economy
▪ = threat of market contagion
▪ DO NOT CONFUSE with systematic risk (undiversifiable risk, measured by beta in the CAPM model)
Risks coveredunder Basell I & II & III regulations
(global banking standards)
- Basel I (1988) - credit risk
- Market risk (1996) - credit & market risk
- Basel II (2007) - credit & market & operational risk
- Basel II.5 (2009) - credit & market & operational risk
- Basel III (2010) - credit & market & operational & liquidity risk
Why is liquidity risk important in banking?
▪ Banks seek liquidity (quick assets) to cover the need to withdraw deposits and to grant the loans of clients.
▪ Unexpected changes in the interest income from credits can result in a rise of the liquidity problem for a bank.
▪ A bank’s need for liquidity can be satisfied by creating either liquid reserves of assets or by their purchase of money or deposits markets
