Didier Sornette: The Quest for Predicting the Next Financial Crisis
In the ever-evolving landscape of global finance, the specter of financial crises looms large, often catching investors and policymakers off-guard. Amidst this uncertainty, Dr. Didier Sornette, a prominent physicist, and economist, has emerged as a leading voice advocating for the scientific prediction of financial crises. His interdisciplinary approach, which merges concepts from physics and finance, offers insightful tools to anticipate market downturns and mitigate their impacts.
A Brief Background on Didier Sornette
Born in 1951 in Paris, Didier Sornette is a professor at the Swiss Federal Institute of Technology in Zurich (ETH Zurich) and has held various prestigious academic positions throughout his career. With a unique background in both physics and economics, Sornette has turned his scientific lens toward the complexities of financial markets. He is renowned for his work on complex systems, critical phenomena, and the use of mathematical models to understand and predict abrupt changes in financial markets.
Sornette has authored numerous influential papers and books, including "Why Stock Markets Crash: Critical Events in Complex Financial Systems," where he explores the mechanics of market crashes through the lens of physical science. His aim is not merely to understand past crises but to develop tools that can hint at when the next one might occur.
The Science of Predicting Financial Crises
Sornette’s core theory revolves around the concept of "super bubbles" and the "log-periodic power law.” A super bubble, according to Sornette, forms when asset prices deviate significantly from their fundamental values over an extended period, leading to an unsustainable speculative frenzy. He identifies key indicators that signal the possible formation of such bubbles, examining fluctuations, investor behavior, and broader economic trends.
Log-Periodic Power Law
One of Sornette’s groundbreaking contributions is the log-periodic power law, which describes how asset prices may exhibit oscillations before a catastrophic decline. This mathematical framework allows researchers to analyze historical price data for signs of impending market corrections. By understanding the periodic patterns that arise during bubble phases, Sornette believes it is possible to predict when these bubbles may burst.
Data-Driven Analysis
Sornette emphasizes the importance of large-scale data analysis in his predictions. By utilizing vast datasets from stock markets, housing markets, and other financial instruments, he has developed sophisticated algorithms capable of identifying precursors to crises. This data-driven approach stands in stark contrast to traditional economic models, which often rely on historical norms and behavioral assumptions.
The Challenges of Prediction
While Sornette’s methodologies have gained traction, predicting financial crises remains fraught with challenges. Market dynamics are influenced by a myriad of factors including geopolitical events, regulatory changes, and shifting investor sentiments, which can introduce unquantifiable variables into models. Additionally, financial markets often operate under the influence of irrational behaviors, making them difficult to predict using purely mathematical models.
Despite these hurdles, Sornette’s work offers valuable insights. He argues that understanding the mechanisms behind financial bubbles—not merely relying on gut feeling or historical trends—can provide a foundation for risk mitigation strategies.
Policy Implications
The ability to predict financial crises presents significant implications for policymakers. Armed with early warning signals, governments and regulatory bodies could implement safeguards, adjust monetary policy, or introduce regulatory measures to buffer the economy against potential shocks. Sornette’s work aims to shift the discussion from crisis management to proactive risk management, offering a flicker of hope in the face of financial uncertainty.
Conclusion
Didier Sornette’s contributions to the field of financial crisis prediction represent a paradigm shift in how we approach market instability. Combining scientific rigor with economic insight, he challenges conventional wisdom and provides tools for anticipating crises. While the complexities of the financial world harbor uncertainties, Sornette’s innovative methods empower us not just to react, but to prepare adequately for the tumultuous rollercoaster of market fluctuations. As we look to the future, embracing a scientific approach to economic forecasting might just be the key to navigating the next financial storm.

Le diapo de la présentation est-il disponible quelque part ou au moins les sources ? merci bien
What an amazing person he is. He is very knowledgeable in his field and on other fields as well. He is very fluent even though english isn't his native language. He is smart, confident and athletic. Seeing him makes me believe there are many great people in this world.
I think the great professor describes characteristics in the market that are manifesting themselves in real-time in 2021. I wonder what 2022 will look like if there is a crash and pension funds cannot make the total monthly payouts to pensioners? Derivatives are so massive that a margin call on a full-scale market collapse would bring down the entire global system. I think this is the impetus of why Russia and China have continued increasing their physical gold and silver holdings. Cryptocurrency is an interesting thought experiment but can be hacked by sovereign nations or priced fixed by central banks. Cryptocurrency currency can be manipulated to strip many of their wealth when bad intentions are the primary goal of bad actors. Excellent short talk by a fascinating professor.
The entire global economic system is a two stroke engine consisting of greed and fear. Greed pushes and creates bubbles, bubbles everywhere, and fear eventually pops these bubbles. Since there no legal consequences to run away greed-speculation, bubbles will continue, our current stock market bubble will eventually or soon pop. The recent tax breaks given to large corporations to reshore their assets from overseas tax shelters were simply used to buy up their own stock to increase price per share; something for nothing. No new products, markets or growth in existing markets were or have been developed with these reshored tax sheltered funds, simply playing with supply and demand. Another dynamic is mergers and acquisitions which provide for economies of scale and subsequent massive job loss. Add to this volatile mix the idea of profit maximization where every penny is squeezed out of supply chains to optimize the profits of large multinationals. What is the consequence, growing numbers of people, families with limited discretionary money. Finally, the trigger is fear where stocks are dumped sometimes by computer algorithms.
and did it predict the current crisis?
Seriously not worth your time to watch this guy. The accent is NOT the problem. Here's the gist: "We have this "'observatory' full of really smart people. We can predict the future of statistical outlier events. I'm not going to tell you how we do it. 'But you should all be VERY afraid that if government doesn't intervene, you'll be sorry."
RE-TAR-DED
I was searching for a method to identify the problem signs at the end of a credit expansion ( which BTW are always fueled by the government that this jack@ss says will save us). I got no such satisfaction.
waste of time
Are global imbalances a result of a world savings glut and manipulation by Chinese authorities or a U.S. mortgage market so awash with cash that you could get a 100 percent mortgage with no income, no job and no assets?
Why is it on planet with millions of Youtube users this lecture has only been watched 140K times ??
Trash. The 2008 economic collapse was not surprising.
I've been familiar with Prof Sornette's work for many years. He is one of few geniuses working in academia today. What a pleasure it was hearing him speak.
he tells us nothing. I would advise Didier Sornette in the video to read the works of Dr. Steve Keen concerning the build up of excessive private debt and excessive growth rates in this in relation to speculation and bubbles. And read New World Disorder at https://www.amazon.com/New-World-Disorder-Terrorism-Democracy-ebook/dp/B076Z7HLR9 to educate himself about bubbles and crashes.
lol Bitcoin bubble 2013.
You can tell a bubble is a bubble by the composition and psychology of the participating investors. When an investment becomes viewed as a popular and easy way to make money, and a broad portion of the investment community is throwing money at it, you have a good idea that a bubble is brewing. I invite anybody interested in investment, economics, philosophy, books or movies to subscribe to my channel. Leave some questions or comments about topics you would like to hear about, if you want.
so practicaly you can't predict the future
a lot of bla bla bla , what a waste of my time
Dragon bullshit
if he was betting on a bubble popping 4 years ago, he lost money

This video is a bit hard to follow due to the accents, sound quality, and the level of sophistication of the conversation. It is worth checking out, however. Nassim Taleb (Black Swan) and Didier Sornette (the speaker of the video above) debating these rare events and their predictability.
The factors that determine a crash are 2 things. Supply & demand.
2008 mortgage brokers giving record number of "NINJA" loans.
Next……
Interest only loans… reaching over 51% of all mortgages will be the tipping point. At this rate it will be 2020! People buying houses they cannot afford…..SIMPLE. impressing other people will cost you dearly!
Cutting a 17 min TED talk about bubbles short: Bubble Genisis = Low Interest rates. Bubble maturity/ pop = Interest Rates rise. 17 min of tedious research compacted. Thank me later.
Can you predict randomness? Are we god yet? Can we predict herd behavior? Can we predict the weather? Answer is no. It's wishfull thinking, and this ted title is the kind of talks you look at when your bored af and seek "dumbening" entertainment. Btw, the best you can do is statistical prediction. Good luck with that – James Simons bought up all geniuses in science areas.
Very thought-provoking…..would love to see what he suggests for the emergent increase of general interest rates in the world's largest mrkets.
Good extrapolation is not a stright line, but a curved one, at 3:44.
With the end of an era, and a 90 million dollar funeral….
I have made a detailed explanation on the financial crisis.
I hope this video is good.
https://youtu.be/3o0LTJaM4D8
no mention of leading economic indicators like the ISM index.
where did all that money go?
Explain where the losses went. Was it cash or simply paper? Why does it trickle down? Is the bettor using money that if lost, effects others? Should that be legal then…as it wouldn't be his money?
LOL… well some-one needed to show this to the Goldman Sacs /JP Morgan cartel..
So relevant right now
any prediction about bitcoin bubble?
he was dead wrong. bubble still hasn't popped.
Wow, so how was that big bubble burst of 2013, Prof Sornette? Another self-important quack claiming to predict the markets.
It's ridiculous how many ignorant people come here not to dialogue with knowledge but to nitpick a respectable academic of his accent, which is not even that strong.
not convinced he was telling the whole truth
Another one is coming if few years & the biggest will be after the electronic money that will shake up down the world societies, wars & planed terror attack will be among those years !! Enjoy the Joy muy soy heheho
Ask Rockefeller family, they are planing those ahead
Sustained growth. How? First of all, without democracy a few tend to take it all. With corporate capitalism, the ultimate goal is to take more than is given. That's called profit. With the increased efficiency of profit maximization, those in control make the decision when to water the garden, how much to water the garden and if to apply fertilizer, how often or when? With greed and no checks and balances, those in control of the economic garden, kill it. To this day in spite of his back peddling rambles soon after the economic downturn, Alan Greenspan has not learned one damn thing. There are too many more just like him.
Didier Sornette is a professor from ETH Zurich, one of the best universities in Europe.
All those dislikes because the cowards/sheeple can't handle the truth xD
Interesting talk but very hard to follow the strong accent.
babon?
Trying to analyze the 07 08 crisis by looking at stocks is incoherent. It was in extremely complicated derivatives and the perverse incentives surrounding the speculative frenzy in those illiquid markets.
This is another out-of-touch academic selling us theories that do not have solid real life experiment. Myself as a scientist/engineer always rely on tests to confirm any analysis even though past analytical results were confirmed by experiment. The problem with these predictions are many parameters interact nonlinearly and you never know when and how a crash would occur. for example Hurricane prediction and modeling is based on allot of measurements, past history and nonlinear dynamics. You can see it is coming but not accurately know where it is going to hit and what time it will hit. The financial market is random event which is heavily influenced by consumer psychology, government policies and a host of other unpredictable factors. I guess Professor Didier should invest all his assets in the financial market since he can predict the outcome. He will be extremely rich !!!
It has been a year since this guy bragged about his predictions. He said the Nasdaq was in a bubble in May of 2013. It was around 3530 at that point. It is currently at 4300.
He sounds ridiculous. Learn to pronounce BUBBLE.
promises more than he delivers
13:38 – Why does the graph of the Chinese bubble stop at 2009? This talk was in 2013 and data is pretty easy to get. That makes me suspicious that this is a bit of a curve-fitting exercise. Though he does say this is 'just the third or fourth act' so maybe the financial bubble indeed goes in pockets of predictability. These so-called non-linear transitions are interesting.
I still have Sornette's book on stock market crashes and power laws, it motivated me to take up finance in the first place.
at time 9:29 no index (readable) of left side of graph….what…trillions of USD? also I came here to see a circuit diagram of the hardware he uses…..where is that?
Slow down Pepe Le Pew… its all scare tactics. Nothing is going happen. It amazes me that all this talk about crap but CRAP never changes. Same thing day after day…. no changes other than the amount of money they will slowly drain for the world population until we are all taxed 100% and giving only what the world governments think we need to live. Oh, and don't forget they will do everything to divide us all and keep CRAP going. Its a promise.
He said that the dragon king should eat the black swan, but the definition is of a black swan is that it is unpredictable, unlike the dragon king. How can one predict the fact that the Greece played around with the numbers?
