Remember the Global Financial Crisis?!
What is a Financial Crisis?
- Almost all wealth is embodied in long-lived assets that pay off slowly over time.
- Some fraction of that wealth is needed to back short-term safe assets used in transactions (“money”).
- Collectively, we cannot all convert our long-term assets to money at the same time.
- A “panic” happens when enough people get nervous and try to convert.
- A “financial crisis” occurs when a panic (or fear of panic) affects the functioning of the financial system.
Why Study the Global Financial Crisis?
- It is an important part of history, by far the most important economic event since the 1930s, and crucial for understanding the world that followed.
- It could happen again.
- We would like to prevent it from happening again.
- If it happens again, we need to be prepared to fight the fire together.
- “This time is different …” (Reinhart and Rogoff, 2008).
- Prior to all financial crises, there is a large increase in the price of at least one asset class. When this price later falls, we retroactively label the original increase to be a “bubble”.
- In the Global Financial Crisis, the bubble was in housing.
- Housing bubbles have been associated with every major financial crisis since WWII.
New Kinds of Money
- Through most of the history of civilization, our monetary needs were met primarily by metal-based currencies.
- The rise of the modern state has allowed for sovereign-backed “fiat” money.
- But … even stable governments have limits and the demand for money can exceed the supply of metal and sustainable fiat money.
- Additional monies are then “manufactured” by the financial system, using private debt backed by collateral.
- The history of financial crises is a tour through sad stories of new monies gone bad.
The Anatomy of a Modern Panic
- For hundreds of years, panics were easy to spot: depositors would “run” to banks to exchange their banknotes for gold, or to remove their deposits.
- The Global Financial Crisis was different, with the panics occurring out of public sight, in the non-bank part of the financial sector. This area of the financial system is often called the “shadow banking” system.
- To fully understand the Global Financial Crisis and the efforts required to fight the panic, it is important to understand the mechanics of this modern system.
Fighting the Panic
- Going into the Global Financial Crisis, governments all over the world were underprepared, with the available tools built for fighting an old-fashioned bank run, not a modern crisis.
- To fight this crisis, these tools – emergency lending, guarantees, capital injections – were extended to creative new uses.
- The evidence shows that this panic-fighting was a success, but this success came at the cost of political backlash, in some cases reduced our firefighting capabilities for the next crisis.
