We have already seen a few of these in recent weeks. German ten-year bund yields jumped from 0.01% to 0.20% in a mere two weeks, a gap once thought unimaginable. The Euro has popped from $1.08 to $1.03.
Since July, we have watched in awe as the ten-year Treasury yield ratcheted up from 1.23% to 2.40%.
The worst is yet to come.
It is a problem that has been evolving for years.
When I started on Wall Street during the early 1980s, the model was very simple. You have a few big brokers servicing millions of small individual customers at fixed, non-negotiable commissions.
The big houses made so much money they could spend some money facilitating counter cycle customers trades. This means they would step up to bid in falling markets, and make offers in rising ones.
In any case, volatility was so low then that this never cost all that much, except on those rare occasions, such as the 1987 crash (we lost $75 million in a day! Ouch!).
Competitive, meaning falling, commissions rates wiped out this business model. There were no longer the profits to subsidize losses on the trading side, so the large firms quit risking their capital to help out customers altogether.
Now you have a larger numbers of brokers selling to a greatly shrunken number of end buyers, as financial assets in the US have become concentrated at the top.
Assets have also become institutionalized as they are piled into big hedge funds, and a handful of big index mutual funds, and ETFs. These assets are managed by people who are also much smarter too.
The small, individual investor on which the industry was originally built has almost become an extinct species.
There is no more "dumb money" left in the market.
Now those placing large orders are at the complete mercy of the market, often with egregious results.
Enter volatility. Lots of it.
What is particularly disturbing is that the disappearance of liquidity is coming now, just as the 35 year bull market in bonds is ending.
An entire generation of bond fund managers, and almost two generations of investors, have only seen prices rise, save for the occasional hickey that never lasted for more than a few months. They have no idea how to manage risk on the downside whatsoever.
I am willing to bet money that you or your clients have at least some, if not a lot of your/their money tied up in precisely these funds. All I can say is, "Watch out below."
When the flash fire hits the movie theater, you are unlikely to be the one guy who finds the exit.
We're hearing a lot about when the Federal Reserve finally gets around to raising interest rates next month that it will make no difference, as rates are coming off such a low base.
You know what? It may make a difference, possibly a big one.
This is because it will signify a major trend change, the first one for fixed income in more than three decades. That's all most of these guys really understand are trends, and the next one will have a big fat "SELL" pasted on it for the fixed income world.
El-Erian has one of the best 90,000-foot views out there. A US citizen with an Egyptian father, he started out life at the old Salomon Smith Barney in London and went on to spend 15 years at the International Monetary Fund.
He joined PIMCO in 1999, and then moved on to manage the Harvard endowment fund. His book, When Markets Collide, was voted by The Economist magazine as the best business book of 2008.
He regularly makes the list of the world's top thinkers. A lightweight Mohamed is not.
His final piece of advice? Engage in "constructive paranoia" and structure your portfolio to take advantage of these changes, rather than fall victim to them.
