8. Financial Crisis 2007-09: Causes, Consequences and Lessons Flashcards
What were the contributing factors to the 2007-2009 financial crisis?
- Mismanagement of financial liberalisation and innovations.
- Long term loose monetary policy (low interest rates)
- Capital inflows from emerging market economies.
- House price bubble fuelled over optimistic expectations prior to 2006.
- Burst of the housing bubble after 2006 as prices corrected towards fundamentals.
Examples of mismanagement liberalisation and innovations
- Financial innovations in the mortgage markets (subprime mortgages, securitisation, opaque CDO, CDO^2)
What is securitisation?
- The process of pooling certain types of assets and selling the related cash flows to third party investors as securities.
What are the Incentives for Mortgage Securitisation? (Banks)
- Loan Originator
- Improved risk implications from off-balance sheet activities and SPVs.
- New tool to meet risk-based capital requirements
- Focus on originate-to-distribute model
What are the incentives for mortgage securitisation (Investors)?
- Pensions Funds, Money Market Funds
- New class of liquid long-term investments
- Cheaper rates and wider pools of capital to loan originators.
- Credit rating agencies: new profiting business.
Why is securitisation not new?
- Creating “stock” or public limited company (PLC)
- Converting corporate loans/debts to tradable bonds.
- Securitisation of loans/debts - CLOs CBOs
- Securitisation of Mortgages - Mortgages-Backed Securities (MBS)
Collateral Debt Obligations
- Created by further securitisation on the junior tranches in MBS
- Can further generate safer tranches than the underlying junior tranches of MBS
- CDO^2s are created from the tranches of other CDOs
- CDO^3s are created from the tranches of other CDO^2s
- Gets more and more complex.
How are CDO’s very sensitive to correlated to defaults across underlying mortgage pools?
- Pool of junior tranches of MBS are assumed uncorrelated.
- Even senior tranches from those further descendent CDOs have nested enormous systematic risks.
- Modest default rate/decline in house prices can trigger the avalanche of values losses to many AAA-rated CDOs and market panics.
What happened with CDOs and subprime mortgages before financial crisis?
- Size of both the origination of subprime mortgages and the issuance of CDOs had become vitally substantial before the crisis.
What is the theory of how Financial System created AAA-rated Assets out of Subprime Mortgages?
- Financial institution packaged and re-packaged securities built on high-risk subprime mortgages to create AAA- rated assets.
- It worked if mortgages didn’t default at once, which it did.
- Therefore, not enough money to pay off mortgage related securities.
What is step 1 of financial crisis/creation of CDOs?
- People take out mortgages.
- Financial institutions groups 100s of SPM into mortgage backed securities (MBS)
What is step 2 of financial crisis/creation of CDOs?
- Securities grouped into tranches by levels of risk and earnings potential for bond holders.
- When people can pay their mortgage in full each month, each group of bond holders get paid.
What is step 3 of financial crisis/creation of CDOs?
- Mortgage payments collected by FI and payments distributed to bond holders.
- Higher rated tranches paid first.
- When monthly mortgage payments not made, payments may not reach holders of lower-rated tranches.
What is step 4 of financial crisis/creation of CDOs?
- Collateralised Debt Obligations (CDOs) were created by taking lower-rated tranches out of the MBS and repackaging them.
- Most of CDO is highly rated, even though built of high-risk of assets.
What is step 5 of financial crisis/creation of CDOs?
Another FI does the same thing with high risk tranches of CDOs, creating CDO^2
