Who predicted the 2008 crash and the financial crisis, and how?

What counts as predicting the 2008 financial crisis?

Predicting the 2008 financial crisis means writing down, before it happened, that a large fall in housing and credit was coming and why. Comments made after Lehman Brothers failed on 15 September 2008 and general warnings that markets might fall sit outside the test. The test for each person below is a dated, documented statement, with a reason attached.

This page applies the scorecard from the guide to stock market crash prediction: size, window, reason, and a public record. It reports only what public sources document, and it leaves motives and accusations aside. Readers who want the full scorecard method can open the page on forecaster track records.

What did Raghuram Rajan warn about before the 2008 crash?

At a 2005 event honouring Alan Greenspan, then about to retire as chairman of the US Federal Reserve, the economist Raghuram Rajan presented a paper titled Has Financial Development Made the World Riskier? It argued that managers in the financial sector were encouraged to take tail risks: small gains most of the time, and rare large losses. Wikipedia records the reception as negative at first.

Lawrence Summers called the warnings misguided and described Rajan as a luddite, according to the same source. After 2008 the ideas were seen as prescient, and by January 2009 the Wall Street Journal reported that few were dismissing them. Rajan’s route was incentives: he looked at how pay and competition shape risk, and he gave a mechanism instead of a date.

What did Nouriel Roubini forecast about the 2008 financial crisis?

Nouriel Roubini warned in 2006 that a US housing bust could lead to a global banking crisis and a deep recession within a few years, according to Wikipedia. The subprime collapse and the 2008 financial crisis followed. Because of these forecasts he became known as Dr. Doom. His route was the housing market and its link to banks.

The record also includes a careful note. As Wikipedia summarises, Justin Fox wrote in the Harvard Business Review in 2010 that Roubini had spent years predicting a different crisis and turned to warning of a housing bust and a global hard landing only in late 2006, and still left the path unclear. A fair reading credits the direction of the call and weighs the earlier misses.

How did Michael Burry act on subprime warnings before the 2008 crisis?

Michael Burry, who ran the fund Scion Capital, began to focus on the subprime market in 2005, according to Wikipedia. He studied mortgage lending from 2003 and 2004 and expected the property bubble to pop as soon as 2007. His reasoning was mechanical: subprime loans with teaser rates would lose value once rates reset, often about 2 years after origination.

He then persuaded Goldman Sachs and other firms to sell him credit default swaps on subprime deals that he saw as vulnerable. Wikipedia reports that some investors in his fund panicked and tried to withdraw their money, that his analysis proved correct, and that it earned him a personal profit of $100 million and over $700 million for his remaining investors. Scion closed in 2008.

What did public data show before the 2008 financial crisis?

According to the EQOS Asia 2008 back-test (2026), the signals sat in public sources from the SEC, the BIS, the FDIC, and Case-Shiller. The price to income ratio of US housing reached 4.6×, against an average of 3.2×. The subprime share of lending rose to 23.5% from 8% in 2003, and subprime defaults reached 14.4% at the end of 2006.

The same study lists CDS contracts of 62,000 billion dollars (BIS) against a world GDP of 54,000 billion, 80% of CDO tranches rated AAA, and banks at 30:1 leverage, where a fall of 3.3% was enough to bankrupt one. Warning events followed in 2007: HSBC announced 10.6 billion dollars of subprime losses in February. The data was visible, and each forecaster above read a different part of it.

How did the EQOS Asia score read the 2008 financial crisis?

The back-test scores the structure of the system and leaves individuals aside. On 2006-2007 data, the global financial system receives a φ(S) of 0.234, below the 0.3 critical threshold, with 6 of 9 dimensions in the critical zone, according to the EQOS Asia 2008 back-test (2026). It places the point of no return about 1.1 years after mid-2006.

The study also lists 4 corrections: transparency, leverage, integrity, and care. Applied in 2006, they would have lifted the score to 0.365, above the critical threshold, and the study estimates that the magnitude of the crisis would have been divided by 5 to 10. Read this as a retrospective, educational exercise run with hindsight, and judge it by whether each input can be recomputed.

What do the 2008 forecasters teach about the next stock market crash?

Three habits repeat across the record. Each forecaster named a mechanism, such as incentives, housing, or mortgage resets. Each relied on data that was public at the time. Each offered a direction and a rough horizon in years, and left the day open. These habits describe a method that you can reuse: study the structure, cite the data, and state the window.

Use them on today’s headlines. A 30-minute pre-diagnostic with EQOS Asia applies the scoring to your own exposure, and the page on EQOS Asia pricing lists the formats. As of October 2026 the practical lesson is to track structure each quarter. This page is general information, not investment advice.
