• Post-global crisis policy area - Few had ”big picture”-perspective on financial system - Few understood scale and impact of interconnectedness - Lots of trust in market’s risk management techniques
• But hard to define - ”the absence of excessive volatility, stress or crises” Gadanecz & Jayaram (2015)
• Macroprudential regulation and supervision
- Stress tests of banks - Extra-monitoring of ”Too big to Fail”-banks - More regulation and supervision
• OBS – stability objective in conflict with market competition objective
Also ideal: Financial stability

Economic ups and downs
• The ”business” cycle • Economic Recessions

• Monetary policy
- Interest rate - Money supply - Exchange rate - Lending to banks - Lender of Last Resort - Buy assets from banks – Quantitative easing
• Financial regulation and supervision
- Charter requirements - Capital and liquidity requirements for banks - Constrain permitted businesses - Deposit guarantees - Continuous moniting of conduct and risk taking - supervision

Economic depressions • ”The Great Depression” 1920s and 1930s more or less
• Worldwide
• LOOONG economic recession = depression
• Financial crisis just the trigger – strucural problems revealed
• Traumantic and significant - for politics and economic policy - for economics discipline - for ideas about how ”not” to do in a financial/ economic crisis - the financial system revealed as ”systemic”

Financial crises
• Types of financial crises
• Causes
• Effects
![Page 19: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/19.jpg)
Financial crises • Different types and combinations
- Inflation crises
- Currency crashes and debasement
- Banking crises
- Public debt crisis
- deflation crises
- Stock market crashes • Main problems
- Problems in ”real economy”
- Problem if financial ”infrastructure” malfunction
![Page 20: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/20.jpg)
Banking crises • Historically quite frequent
• Occurs in all countries
• Problematic due to link to real economy - services - infrastructure
• Rule of thumb is to rescue illiquid but solvent banks
• Problems due to lack of info, ”too-big-to-fail”, ”capture”
![Page 21: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/21.jpg)
Bank runs and their systemic contagion
• Banks only hold fraction of deposits ready for direct withdrawal • If too many depositors withdraw
simultaneoulsy, bank is forced to sell assets at any price…
• Run + “fire sale” of assets spread to other banks
• Policy responses - Lender of last Resort - Deposit guarantee - Bank to hold buffers – liquidity & capital
![Page 22: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/22.jpg)

Inflation and deflation crises • Reinhart & Rogoff definition (2009): Inflation higher than 20%
over one year
• Problems with inflation:
- Savings and wages lose purchasing power - Loans lose in ”real” value – so banks reluctant to lend - Driven by expectations about more inflation to come, tendency for self-enforcing
• Deflation crisis – the opposite - Prices goes down, purchasing power goes up - Makes sense to wait with purchase – slows down economy
![Page 24: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/24.jpg)
Worst case: Hyperinflation • Zimbabwe • Germany during and after WW1:
1914 1923 1 $US = 4,2 Mark 1 $US = 4,2 trillion Mark
![Page 25: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/25.jpg)
Sovereign debt default:
• A country stops paying on its loans / do not repay loans
• In practice a default triggers negotiations on:
- what interest rate to pay - how much to repay - when payments are due - In what currency - Whom to pay
![Page 26: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/26.jpg)
Greek sovereign debt and repayment
![Page 27: Economic and financial crises, an overview](https://reader031.fdocuments.us/reader031/viewer/2022020622/61ebbca4cf55e7453c6e67b6/html5/thumbnails/27.jpg)
Causes • Financial globalisation itself?
• Cost and ease of borrowing
• Self-enforcing momentum via booming asset markets (housing, securities etc.)
• ”Experts” (Galbraight) saying ”This time is different” (Reinhart & Rogoff) because ”we’ve solved it” (Lucas)
• Incompetence, greed etc.
• Institutional failures – e.g. Missing macroprudential outlook
