A Full Rundown of the 2008 Global Financial Crisis — S&P 500 -57%, 5.5 Years to Recover
When the belief that "home prices don't fall" collapsed, global finance was shaken to its core. What happened in 2008, and how far did the index fall and when did it recover?
What Collapsed — a Crisis That Began at Home
In the early-to-mid 2000s, U.S. home prices kept rising amid low rates. Banks even issued so-called "NINJA (No Income, No Job, no Assets)" loans without properly verifying income, employment, or assets, expanding mortgages (subprime) even to people with low credit.
These loans were sliced up and repackaged as mortgage-backed securities (MBS), and then as collateralized debt obligations (CDOs) bundling multiple MBS, and sold to investors worldwide. As credit rating agencies handed out top ratings (AAA) freely, the risk spread everywhere with the face of a "safe asset."
When home prices turned down and loan delinquencies rose, these securities went bad all at once, and the losses spread in a chain to banks, hedge funds, and pension funds.
How Far Did the S&P 500 Fall
The S&P 500 fell about -56.8% from its October 2007 high to its trough on March 9, 2009. It was a drop that exceeded a halving.
Recovery of principal (the 2007 high) came around March 2013, taking about 5.5 years from high back to high. Measured from the trough (March 2009), it took about 4 years to a new record.
In other words, even if you held on without selling at the worst moment, just returning to your starting point took more than 4 to 5 years. "It recovers eventually" and "can you endure the time in between" are entirely different problems.
The drop of about -57% is consistent across sources at around -56.8%. If you lose -50%, you need +100% to recover your principal.
The Lehman Bankruptcy That Became the Symbol of the Crisis
On September 15, 2008, the investment bank Lehman Brothers filed for bankruptcy protection (Chapter 11). With about 639 billion USD in assets, it is recorded as the largest bankruptcy in U.S. history.
When the government did not step in to rescue it, the market was gripped by the fear that "no one is safe," Lehman's stock crashed 93%, and the Dow also plunged -4.5% that day. Afterward, governments and central banks around the world prevented a systemic collapse with massive liquidity injections and bailouts.
The Lessons This Crisis Left
First, even an asset deemed "safe" can be dangerous if its structure is complex and hard to understand. Second, a crisis can spread through the whole system rather than an individual stock, so diversification alone cannot avoid every drawdown.
Third, the most important thing is the "time" to recovery. More than the number -57%, the fact that you had to endure that state for 4 to 5 years broke most investors. That is why it matters to know the size of the drawdown and the duration of the loss in advance and allocate assets accordingly.
Frequently Asked Questions
Q. What would have happened if I sold at the trough back then?
Anyone who cut losses near the March 2009 trough missed the recovery and new highs that followed. What past data shows is that "the drawdown recovered if you endured it," but this does not guarantee future returns. The key is to decide before investing whether "this is a weight at which I can endure a -50% stretch."
Q. Could the 2008 crisis come again?
No one can predict whether or when a specific crisis will recur. But even in different forms, large drawdowns have repeated historically. Rather than trying to predict, it is more realistic to have an asset allocation and cash buffer that can endure any drawdown.
