Here is a very familiar financial bubble, in pictorial form:

And this is what it looks like, charted:

In those days, of course, tulips at least had to be able to flower. But things have changed since then.

There are three key stages in the lifecycle of a financial bubble:

  1. The "Free Lunch" period. A long, slow buildup of price distortion, during which investors convince themselves that rising prices are entirely justified by fundamentals, even though it is apparent to (rational) observers that they are buying castles built on sand.
  2. The "This is nuts, when's the crash?" period. Everyone knows prices are far out of line with fundamentals, but they carry on buying in the irrational belief they can get out before the crash they all know is coming. Speculators pile in, hoping to make a quick profit. Prices spike. 
  3. The "Every man for himself" period (sorry, FT, I couldn't find a reference for this one). Prices crash as everyone runs for the exit. This can happen a number of times, separated by brief periods of stability when everyone congratulates themselves on a lucky escape. But they are wrong. The ship is sinking. 
This is what the three stages look like, charted: 

The sharp-eyed among you will have noticed that there are no tulips in this chart. That is because financial crashes don't have to involve tulips. This one, of course, is stocks. 

So is this one, though not the same kind of stock:

This is the dot-com bubble at the turn of the century. Characteristic shape, again: long slow buildup, noticeable spike, and a crash in several waves. Classic. 

I rather like this one, too: 

This shows the unsustainable buildup of oil prices from about 2004 onwards, culminating in a simply massive spike and single dramatic crash (no waves) in July 2008. Of course this had no connection whatsoever with the failure of Lehman Brothers in September 2008, did it? 

Oh, and in case you were wondering - the second, longer-lasting spike is caused by the Fed pumping up the oil price with QE. The oil price crashed again in 2014 when the Fed ended QE. Tulip mania, central bank style. Don't anyone ever say that QE isn't inflationary. 

Now, you are no doubt wondering what all of this has to do with the crypto-title of this post. Well, it just so happens that a fine example of the asymmetric herding I have been talking about is happening right now. Cryptocurrencies are undergoing a massive sell-off. 

Here is Bitcoin's price chart, today (from Coindesk):

Here is Ethereum:

Ethereum Classic (from Coingecko):

Litecoin (this from


In fact, just about every cryptocurrency is selling off - see the list here at CoinMarketCap. And as far as I can see, they all show the characteristic shape of a financial bubble, though some coins are late to this party, so only show the speculative spike typical of the "This is nuts" stage. 

And the irrational beliefs underlying financial bubbles are also there. For months, there has been discussion in the financial press about the possibility of Bitcoin and Ethereum being in a bubble: but hardened investors dismissed it all. And are still dismissing it, despite the compelling evidence that not only is this a bubble, it is bursting.

Crypto-tulips are no more valuable than real ones. And crypto-investors are no more rational than any other sort of investor. Pride goeth before a nasty crash.

  1. Bitcoin wants to be the far west, but when it comes to publicly traded assets with "deep, liquid" markets, could we insist that sales are concluded 1 week after a seller lists a lot for sale, at whatever the market price is that day? That would remove the macho component of thinking oneself the quickest.

    Another idle thought is a stampede tax: a tobin tax whose rate would spike in the case of a run. The rate could be set by an algorithm, adjusted from minute to minute based on transaction volumes.

  2. I think you will find this article pretty interesting

  3. I've always liked tulips. I spent a good career investing in companies that needed capital (or, more precisely, were obliged to pay off the shares they issued back when they did).

    Cryptos, however, seem like a solution to a problem that only will exist in a dystopian-libertarian future when we only trust the Matrix of miners. Which so far, has shown itself not vulnerable to, but absolutely built in order to encourage/exploit the herding you mention, for the private gain of the first-to-the-Ponzi game.

  4. Like the new design too, but where has the blog roll gone? It led me to some very interesting blogs I would probably not have discovered otherwise.

    1. Click on the arrow at the top of the screen next to "Coppola Comment". That takes you to the home screen. Then click on the three dashes at the top LH side of the home screen. Scroll down until you find the "Blogs I enjoy reading" bit.

  5. This article completely fails to understand or even mention what is happening in the market right now.

    It is just lazy to overlay this with that and say they are the same, retrace and consolidation is to be expected in any asset that has seen such explosive growth.

    Also "The tulip bubble was not really a bubble it was actually a re-allocation of contracts to a swaption. By changing a contract to swaption they allowed government officials to get out of their contract and that effectively collapsed the price " - Craig Wright.

    1. I provide market charts for several different crypto-currencies, but somehow I fail to mention what is going on in the market right now?

      What is going on in the market right now is a sell-off. A major price correction. And as I explained in my post on asymmetric herding (see the link in the post), major price corrections are the inevitable consequence of explosive asset price growth that is divorced from fundamentals and in the end largely driven by speculation.

      How the final spike in a price bubble is created and collapsed is irrelevant. It is still a final spike and collapse in a price bubble.

    2. Yes, somehow you completely fail to mention anything that is going on in the market right now i.e. what is driving the charts.

      What is going on in the market right now is consolidation, not a sell off or even a correction, people are taking profits after seeing profits of over 5,000% in a very short period of time.

      Another contributing factor (for the Ethereum eco-system at-least) is EOS and Tezos dumping their investors contributions to their ICO's onto the market. Of-course BTC scaling issues are weighing heavily on the whole market too.

      The real bubble right now is in the 'real-world economy' with a replay of the sub-prime mortgage crisis, this time with cars.

    3. Whatever you want to believe. One person's "consolidation" is another person's price correction.

      I agree the ICOs are contributing to the correction, as are the scaling issues for both BTC and Ethereum and the growing evidence that there is a fundamental conflict between providing a fast efficient payments service and delivering the sort of returns on investment that crypto investors have come to expect.

      The subprime autoloan problem is indeed worrying, as is student debt. But that does not mean the crypto industry is not in a bubble. It is.

      Worth remembering that the growth and bursting of bubbles is a necessary part of the development of any new technology. It will be interesting to see what emerges from this period of Schumpeterian destruction.

  6. Jerrod Seisyll, your comment has been removed because it consisted entirely of a sustained personal attack on me. It contained no useful analysis and contributed absolutely nothing to this debate. You are welcome to post here if you have interesting things to say. But any further posts that consist largely or entirely of personal attacks will be deleted.

  7. Your market analysis consisted of nothing more than price observations . The only relevant point was that prices were moving in all markets . But far too early to call end of bubble , assuming there is one . And in your stage one , you assume immediate price distortion . Not necessarily the case . Valid points Imo . As for personal attacks , I try to keep it light hearted . But like a certain very British dude , you appear to be able to dish it out , but ... . Anyway , as you threw mud at your comment person on twitter , I assumed mud throwing = o k . Still , delete as you wish .

    1. The rules for commenting on my blog are very simple and I expect everyone to abide by them:

      - be polite and refrain from personal attacks on me or on other commenters
      - stick to the topic.

      I delete posts that violate one or both of these rules. Repeat offenders may be permanently banned from commenting. This policy is clearly stated on the "About This Blog" page.

      What I do on Twitter has nothing whatsoever to do with the rules for commenting here. This is my site, and I set the rules. Abide by them, or don't comment.

  8. This comment has been removed by the author.

  9. Thank you. I for one enjoyed the piece and think you are most likely correct!

    It's interesting to note that the August 1st deadline regarding scaling is now largely redundant, so it would seem like a time for bullish sentiment to take the fore, although there's no denying the evidence in those charts...
