US 2007-2009 Financial Crisis
Use this file when: Understanding the 2008 case as a template for rapid policy response preventing an ugly deleveraging. Also for quantifying housing bubble indicators.
The Housing Bubble: 2004-2006
“From 2004 to 2006, home prices increased around 30% and had increased more than 80% since 2000, supported by increasingly liberal lending practices. That was the fastest pace of real housing price increases in a century. The price rise was classically self-reinforcing.” — a-00215
Pre-crisis diagnostics:
- Home prices: +80% over 5 years, +30% in 2 years
- Fastest appreciation since post-WWII (the only comparable period)
- Mechanism: self-reinforcing (higher prices → higher collateral → more lending → higher prices)
- Credit standards deteriorating: stated income, subprime, NINJA loans
“At its pre-crisis peak, debt service reached 68% of GDP, making the United States vulnerable to a shock — which came in the form of a housing bust.” — a-00221
The Crisis Depth: January 2009
“Virtually every economic indicator looked to be falling extremely quickly. In a single day in January 2009, reports of employment cuts across companies totaled 62,000. In addition to weak economic growth, there were still at least five major financial institutions at risk of failure: Fannie Mae, Freddie Mac, AIG, Citigroup, and Bank of America.” — a-00217
This is what systemic crisis looks like: five SIFIs simultaneously at risk of failure, 62,000 job cuts in a single day, all indicators deteriorating.
2007-2009 quantification: a-00221
- GDP: -4% (vs -26% in 1929-33)
- Stocks: -50% (vs -84% in 1929-33)
- Homes: -24%
- Debt service at peak: 68% of GDP
The milder outcome vs 1929 was entirely due to policy speed and scale.
The Policy Turnaround: March 2009
“Policy makers at the Fed and the Treasury were planning a coordinated set of ‘shock and awe’ policies designed to shore up the financial system and provide the money needed to make up for contracting credit. These policies were much more aggressive than earlier easings, and were released in a sequence of mega-announcements. How they were announced magnified the impact.” — a-00218
Key 2009 policy elements:
- QE1 (November 2008, extended March 2009): Fed purchases $1.75 trillion in MBS/Treasuries
- TARP: $700B bank recapitalization
- ARRA: $787B fiscal stimulus
- Stress tests: banks forced to raise capital or close
- PPIP: Public-Private Investment Program for toxic assets
The announcement effect was as important as the substance — “shock and awe” signals decisive intervention, which changes expectations.
The Beautiful Deleveraging Onset: H2 2009
“In the second half of 2009, the policies reduced risks and increased the buying and prices of ‘riskier’ assets, and the economy began to recover. This shift was analogous to others that produced ‘beautiful deleveragings.‘” — a-00219
The template was correctly executed:
- Nominal growth > nominal interest rates ✓
- Risk assets rallied ✓
- Debt/income began falling ✓
- No deflation spiral ✓
Stocks bottomed March 9, 2009. From that bottom, S&P 500 returned ~400% over the next decade.
Lessons for Future Crises
- Speed matters more than precision — acting decisively on imperfect information beats waiting for clarity
- Scale credibility — policy must be large enough to overshoot, not incremental
- CB + fiscal coordination — both tools required simultaneously
- Bank recapitalization (not just liquidity) is required for solvency crises
- Announcement effect amplifies the policy impact
2008 as Archetype: Sector Debt to Systemic Contagion
“In 2008, there was a big deleveraging—the global financial crisis. It was led by the mortgage/real estate sector being financed by a lot of debt, which led to big debt problems that spread quickly to affect almost everyone in all countries, like the Great Depression in the 1930s.” — a-00111
The mechanism: sector-specific debt (mortgage/real estate) → securitization spread risk across the system → contagion when the collateral collapsed. The pattern applies across asset classes and geographies — the sector doesn’t matter as much as the degree of leverage and how widely the risk was distributed. — a-00111
Liquidity vs Solvency: The Critical Distinction
“we are approaching a solvency crisis that we think is about to be the next major chapter of this deleveraging. Liquidity crises occur because of a cash shortage—which central banks can fill. Solvency crises occur because net worths are genuinely wiped out—which is much harder for central banks to manage, because they need to be recapitalized.” — a-00216
The 2008 policy error: misidentifying solvency as liquidity. The Bear Stearns rescue (March 2008) implied liquidity; Lehman’s collapse (September 2008) confirmed solvency. A CB can resolve liquidity by lending freely; solvency requires recapitalization — writing down assets, injecting equity. The failure to act fast on recapitalization (TARP initially rejected by Congress) extended the crisis. — a-00216
